Skyworks Revenue Down for Q2

RF/microwave integrated device manufacturer, Skyworks Solutions, Inc. (NASDAQ: SWKS) announced their second fiscal quarter 2009 results on Thursday. Revenue for the quarter was $173.0 million, a 14 percent decrease from $201.7 million in the year-ago period and versus guidance of $168.0 million.

Non-GAAP operating income was $21.2 million in the second fiscal quarter with diluted earnings per share of $0.12, $0.02 better than consensus estimates. On a GAAP basis, operating loss for the second fiscal quarter was $3.7 million and diluted loss per share was $0.03, including $19.4 million of previously disclosed charges relating to the Company’s operating expense reduction initiatives.

“Despite the challenging economic backdrop, Skyworks delivered solid financial results in the second fiscal quarter of 2009 driven by our diversification, scale advantages, fab-lite strategy and improved cost structure,” said David J. Aldrich, president and chief executive officer of Skyworks. “Offsetting general market weakness, our performance was highlighted by strength in energy management and smart grid technologies, China 3G base stations, smart phones and push-to-talk applications. At a higher level, we believe our results demonstrate that Skyworks is gaining share in the broader analog semiconductor market and is creating a highly differentiated business model.”

Business Highlights

* Maintained non-GAAP gross margin of 40 percent (38 percent on a GAAP basis)
* Reduced operating expenses by more than $25 million on an annualized basis
* Partnered with Itron, a leading energy technology provider, to meet increasing demand for smart meter technology
* Captured key design wins at Huawei and ZTE for 3G and 4G base station solutions
* Unveiled a suite of low noise amplifiers targeting ultra-high performance infrastructure, GPS and satellite radio applications
* Supported an increasingly popular e-book reading platform developed by one of the world’s largest online retailers
* Expanded Qualcomm baseband partnership leveraging higher value front-end modules and encompassing a growing number of 2G, 3G and HSDPA reference designs
* Named Supplier of the Year for the second consecutive time by LG Electronics

Third Fiscal Quarter 2009 Outlook

“Although we remain cautious on the macro-economy, Skyworks intends to resume top and bottom line growth in the current quarter through share gains and participation in new markets,” said Donald W. Palette, vice president and chief financial officer of Skyworks. “Specifically, we expect June quarterly revenue to be up 5 percent sequentially with expanding margins driving non-GAAP diluted earnings per share of $0.14 - - - a 15 percent sequential improvement in profitability.”

TriQuint Reports Q1 2009 earnings

As expected, Q1 2009 revenue was seasonally down, compared to Q4, in a challenging economic environment of inventory correction and reduced short term demand. Still, total revenue was up 7% as compared to Q1 2008. These results were led by Handset growth of 24% and Defense / Aerospace growth of 23%. The reduction of both channel and TriQuint inventory drove Oregon fab’s utilization to 35% and pushed gross margin down, resulting in a Non-GAAP net loss of ($0.07) per share on revenue of $118.9 million, both on the favorable end of our expectations. Fortunately, an inflection point of increasing demand occurred late in the quarter as Handset inventory normalized.

Highlights from the quarter included:

* Revenue for the first quarter was $118.9 million, up 7% from Q1’08
* Inventory was reduced $19.8 million from the fourth quarter of 2008
* Book to bill ratio for the quarter was 1.14
* Honored by Intel Corporation with its 2008 Preferred Quality Supplier award
* Achieved cumulative shipments of more than a half billion total RF modules
* Introduced the market’s first SMT device for 40Gb/s optical communications
* Unveiled TRIUMF™, 3G/4G converged mobile solution
* First design win for TriPower™ – Next generation infrastructure RF power solution
* Fulfilled initial production orders of GaAs and BAW devices for multi-nation F-35 Joint Strike Fighter

Commenting on the results for the quarter ended March 31, 2009, Ralph Quinsey, President and Chief Executive Officer, stated “The global economic downturn prompted lower inventory at our customers and very low factory utilization in Q1. We are now seeing signs of inventory normalization in some of our markets which should translate into stronger demand in the coming months."

Quinsey also commented that, "Market strength in smart-phones, the acquisition of WJ Communications and positive momentum in major military programs contributed to our year over year growth.”

AWR Reports Good Results

On Monday (April 20th) high-frequency EDA supplier AWR® announced record annual revenues for its 2009 fiscal year that ended March 31, as well as for the year’s fourth quarter, and record backlog as it enters the 2010 fiscal year. This achievement marks the twelfth consecutive year of revenue growth for the company and was broad-based, with strong bookings throughout Europe, North America and the Asia Pacific region from both new and existing customers. It is an impressive streak for the software innovator - especially in light of the worldwide recession.

AWR executives attribute the performance to several factors. The company acknowledged that it had received two of its largest orders in company history, both from top-tier manufacturers of third-generation (3G) wireless transceiver modules for smart phones. The company also claimed to have experienced strong growth within existing aerospace and defense accounts as well as from new customers that switched to AWR products from competing tools.

I’ve always believed that tough times calls for digging in and doubling your efforts to do what has made one successful in the past. This effort needs to also be balanced with flexibility in order to change to changing times. Based on this latest fiscal report, AWR seems to being doing both of these quite well. How is your company weathering the storm? Is the performance of your company better than expected? Are we turning a corner in this recession? Tell us about your success.

Oracle to Acquire Sun Microsystems

Back in the mid-80s, do you remember sign-up sheets for workstations, which were extremely expensive and in short supply. Design software such as MDS (HP), Libra (EEsof) and Harmonica (Compact Software) required the high performance computing only available on these machines and EM simulation software such as HFSS was not yet widely available. Many of us (junior) engineers had to work later in the evening waiting for a workstation to became available. Do you remember the Unix wars between the proponents of BSD from Univerity of California, Berkeley and System V from AT&T? BSD Unix vendor Sun Microsytems and AT&T would start working together on a unified system in 1987. Eventually a workstation for every design engineer would become a reality. Workstations and PCs have certainly come a long way since then, and today's simulators often utilize compute farms to address ever-larger problems, broad parameteric sweeps and optimization, yet hearing that Oracle Corp. plans to acquire Sun Microsystems Inc. for $7.4billion, brought back memories of those days many years ago.

In the deal, Oracle trumped IBM by picking up what might prove to be a software treasure trove that includes the popular MySQL open-source database as well as Java.
Oracle said it will pay $9.50 per share in cash for Sun, or $5.6 billion net of Sun's cash and debt. The move follows Oracle's purchases of a raft of companies in the past few years, including Siebel Systems, PeopleSoft and BEA Systems.

Sun shares rose by $2.41 to $9.10 in trading about an hour after the market opened, while Oracle shares declined by $1.03 to $18.03. Shares of the buying company in big mergers and acquisitions often sink at first as investors debate the relative merits of laying out large amounts of cash for the acquisition.

On a conference call Monday, Oracle CEO Larry Ellison said Java and Solaris were the two main reasons Oracle purchased Sun, a move that is in line with Oracle's acquisition strategy to buy companies with "market-leading products."

Calling Java "the single most important software asset we have ever acquired," he said Oracle's Java-based middleware business, bolstered first by the BEA acquisition and now by the purchase of Sun, is on track to become as large as Oracle's flagship database business. Oracle's Fusion middleware is based on Java.

Oracle also considers Solaris "by far the best Unix technology available in the market," which is why more Oracle databases run on that OS than any other, Ellison said. He said Oracle's enterprise customers running both products will be able to experience new benefits by technical integration of the products.

Anyone else care to share some old Sun Solaris SPARC memories?

WCAI Wireless Policy Summit is Approaching

It was announced this week that Sean Maloney, executive vice president and chief sales and marketing officer at Intel Corporation will give the opening keynote address at the WCAI’s Wireless Policy Summit on May 5 in Washington, DC. The Summit, being held at the Grand Hyatt Hotel, will gather key officials from government and industry in an open forum for the exchange of ideas between attendees. This event is an ideal opportunity to meet face-to-face with top decision-makers who are shaping the future of the industry in 2009 and beyond. As the new Administration is acting on its commitment to bring broadband access to all Americans, the Summit will examine the role of wireless in the broadband stimulus package, universal service, open access, net neutrality, and more. WCAI web site

In light of the current economy, the summit seems well timed. On April 8th, the FCC adopted a notice of inquiry seeking public comment on the national broadband plan that the Commission is required to prepare under the American Recovery and Reinvestment Act of 2009 (ARRA). Fred Campbell of the WCAI commmented on his blog stating - "Wireless broadband platforms should play a leading role in the Commission’s plan to ensure that every American has access to broadband capability. Wireless technology is the most cost-effective way to provide affordable broadband both to sparsely populated rural areas and urban centers. Moreover, as the only broadband platform that is capable of providing access everywhere, all the time, wireless broadband offers mobility – a connection to every person whether at home or on the go. These capabilities make wireless broadband essential to achieving the FCC’s goal of universal broadband connectivity.”

Microwave Journal and its sister publication Telecommunications will be keeping a close eye on the lobbying efforts to develop wireless broadband platforms to address the ARRA of 2009. Stay tuned as we will be working with all parties with a stake in this area. Meanwhile - are you heading to this forum? We'd love to hear from you.

MWJ April Issue is Out - Let the Battle Begin

Our April issue themed "Amplifiers and Oscillators" just came out with the lead story about the advantages and disadvantages of Si versus GaAs based semiconductor technologies for power amplifier applications (the discussion is contained to lower power levels, <1 W where they both have good performance). It discusses how Si has made many strides in this arena and could be the preferred technology for many applications.

There is no doubt that GaAs is usually better suited for higher power applications but in the high power realm, LDMOS (at lower frequencies) and GaN have made significant inroads into the market. So it seems GaAs is always getting squeezed in the market with competition on both ends. We will address this high power market in our June issue lead story as LDMOS and GaN face off. Please read the article and let us know your feedback - I am sure the GaAs proponents will have something to say!

GaAs Downturn Predicted to Not Be as Severe as 2001

Strategy Analytics issued a report “GaAs Industry Downturns 2001 vs. 2009," where the Strategy Analytics GaAs and Compound Technologies service reiterated previous projections of a 5% - 6% drop in GaAs industry revenues for 2009, and explains why the current downturn will not be as extreme for the GaAs industry as in 2001.

As SA said previously, the GaAs industry hit a wall in the last quarter of 2008. The effects of a global economic slowdown finally caught up with the handset market—and other end markets—in which GaAs technology is used. However, Strategy Analytics believes that the expanding demand for bandwidth coupled with better managed inventory corrections will save the industry from seeing the precipitous 25% drop suffered in 2001.

Broadband Stimulus Funds

One hot topic at CTIA and certainly in the broadband market is the pending stimulus money that will become available from the federal government by Sept 2010. The amount to be allocated to broadband projects is $7.2 billion which is a large sum but after it is broken down in projects, it might not look so large. There has to be at least one grant per state (plus DC and some territories) and 75% must go to rural projects so that is where the emphasis will be for providers. They are encouraging people to team up to take a more holistic view of projects but there will certainly be barriers to doing this. There are also incentives for providing services to unserved and underserved areas.

The legislation is still being worked and public inputs are still being taken but it could be very good for the wireless market providing the funds make it into the hands of the manufacturers. Does anyone has any insights or additional information about the stimulus funding?

CTIA Keynote Close Out

Steve Largent kicked off the final keynote with some highlights of the show such as Blackberry launching their apps store, the merging of wireless and medical applications and a few new product launches from the big carriers. He showed a video of how the industry is recycling and leading in "green" efforts. Largent then introduced the final speaker, the honorable Al Gore.

Gore reviewed the history of information distribution and how it has affected the balance of power from the few to the many. He stated there were only 50 web sites online about the time Clinton and he took office compared to today where there are billions. He drove the concept that we have a climate change, security and economic crisis. The common thread in these is our reliance on carbon based energy so we must act quickly to move away from that situation. He stated that wireless is a key tool to solving these problems and challenged everyone to contribute and lead the effort. He said we should have more than a financial incentive as it will improve mankind!

Many people at the show enjoyed the previous day's keynote on how advanced wireless medical applications were being developed. They showed how you could monitor your vital signs on your smart phone and send them to your doctor.

The other subject that was discussed on the floor was the government incentives for the expansion of broadband services around the country. It seems like the funding is still not completely defined but everyone is looking forward to them being released. However, if it is like most government programs, it could be some time before we see any release of those funds.

Did you see anything interesting at the show or have any comments?

Having Some Fun at CTIA

The PowerWave booth is always huge stretching across the middle of the main exhibition hall. This year they have a formula one race car simulator that is very realistic. You provide them with a little information and then get your ride. I have not come across any other interactive displays yet other than presentations and music.

After a long day at the show, we decided to stay in the Mirage and have a "little" sandwich at Carnegie's. Then came the turkey club that was about a foot high and the pastrami that has a full 2 pounds of meat. We did our best to finish them but we were not very successful. Our publisher, Carl, always poses for the food pictures.

A-GPS Big at CTIA

GPS is being commonly added to smart phones for location based information and services. However, GPS in these phones is not always that accurate and can have slow response times. Assisted GPS (A-GPS) will solve these problems with help from the cell towers to complement the internal GPS information being gathered by the phone. It is a hot topic at CTIA and companies are releasing test solutions to meet the needs of deploying them.


Agilent Technologies Inc. introduced GS-9000 A-GPS Design Verification Test systems designed around the 8960 wireless communications test set's new A-GPS assistance data messaging test capabilities. The capabilities support A-GPS validation, Total Isotropic Sensitivity testing and A-GPS pre-conformance testing for mobile devices. With this introduction, Agilent's 8960 test set offers the industry's best price/performance one-box tester for use in A-GPS base station emulation applications across the entire R&D lifecycle.


Spirent Communications, a mobile device, application, and wireless network testing company, has partnered with ETS-Lindgen, a provider of RF chambers and antenna measurement solutions, to integrate Spirent's UMTS Location Test System (ULTS) with ETS-Lindgren's EMQuest Antenna Measurement Software. This will enable the ability to test product in compliance with the upcoming 3.0 release of the CTIA's Test Plan for Mobile Station Over the Air Performance, which will become mandatory on all CTIA authorized test labs.

CTIA Central Hall

So each year I like to give out my own best booth award to the glamorous handset companies that go all out for CTIA. I think it usually comes down to LG and Samsung. Last year I liked the LG booth the best and although it was great this year, Samsung gets the award for the intriguing display pictured here. It is made up of individual cell phone images which constantly change.

The central hall was very busy in the afternoon and I enjoy going to the Asian country pavilions which each have several microwave component companies. They typically make some very good isolators, diplexers, duplexers and integrated assemblies. One that stood out was Admotech which makes components and was featuring their integrated front end WiMAX assembly.

I will be spending more time in this hall later since it is so large.

RF/Microwave Pavilion Opens at CTIA

The RF and Microwave Pavilion opened at CTIA today and the reception was strong. The Pavilion is located in the South hall toward the front on the main isle so traffic was good.

I visited all of the booths today in the pavilion and will have a complete wrap up in a few days after I return. But the most interesting product so far is the Peregrine UltraCMOS products. They are making products that are solving many of the high power, high linearity and fast switching times needed for multi-throw switches, digital attenuators and tunable circuits. Included is a photo of one of their patterned Si on Sapphire wafers. See the previous entry describing their release of new digital step attenuators and they have more products coming.

Another very interesting meeting I had was with Spirent who I was not very familiar with until today. They make testing solutions for real world testing of more types of wireless systems and announced that ETS-Lindgren now supports Spirent's UMTS Location Test System. This will allow wireless device manufacturers to quickly and easily add Spirent's A-GPS instrumentation to ETS-Lindgren's over the air wireless test solutions.

The Testing Solutions Pavilion is right beside the RF and microwave Pavilion so I was able to visit Anritsu and others there. Anritsu has some new USB power meters available that I will also describe in the wrap up after the show. The central hall has all of the large booths and country pavilions. I will have follow up on details about my visits to central hall next.

CTIA Kicks Off

I got in last night and Vegas seems as busy as ever - there are several trade shows in town besides CTIA which by itself is very large. I will be going over to the exhibition soon as it opens at 11 but the news is already pouring in. It looks like femtocells are hot while high capacity microwave backhaul and LTE continue to get a lot of attention.

Peregrine Semiconductor Corporation released three new UltraCMOS(TM) Digital Step Attenuators (DSAs) in the expansion of its popular 50 Ohm DSA line. Building on their high-performance predecessors, along with flexible serial and parallel interface logic these new HaRP(TM)- enhanced devices also offer highly flexible attenuation options by covering a 31.5dB attenuation range in 0.5 dB or 1.0 dB steps. They have really expanded their portfolio from basic switches a while back.

Agilent Technologies introduced its Signaling Analyzer Real Time (SART) for Femto. This first-to-market technology extends the test industry's most complete, end-to-end wireless analysis and troubleshooting solution to femtocells, which access wireless networks via consumer broadband connections. The platform supports both standards-based and proprietary femtocell implementations.

ETS-Lindgren announced an integrated solution that lets wireless device manufacturers test their products for compliance with the CTIA – The Wireless Association®’s new requirement for over the air performance testing of Assisted-GPS (A-GPS) enabled mobile devices. With the upcoming release of the Version 3.0 of the CTIA’s Test Plan for Mobile Station Over the Air Performance, this requirement will become mandatory for certification testing at all CTIA authorized test laboratories (CATLs).

Rogers Corporation is featuring a variety of its high-performance materials and is participating for the first time as part of the RF Zone. Visitors can discuss their design challenges with Rogers' applications engineers, and learn more about Rogers' state-of-the-art circuit-board materials.

Cobham sells M/A-COM Technology Solutions

It must have been very difficult in this market but Cobham pulled it off and sold the commercial components portion of M/A-COM, M/A-COM Technology Solutions (MTS), to John Ocampo for $30 million in cash, $30 million in senior loan notes secured on the MTS assets and $30 million dependent on future revenue in the period 2010 to 2012. John is a very experienced RF/microwave person in the industry having been on the board at Sirenza and started Vari-L many years ago. MTS is exhibiting in the RF/microwave Pavilion at CTIA.

At the time of the acquisition of M/A-COM on May 13, 2008, Cobham said it planned to divest the commercial business segment MTS, as it was not core to the Group's strategy (Excluded from the sale are cash and the freehold of the Walker Building in Lowell, Massachusetts valued at $10 million). MTS recorded revenue of some $275 million and operating profit of less than $10 million.

I think this is a good transaction for MTS and its employees to be purchased by an experienced entrepreneur and leader like John Ocampo. This leaves the original M/A-COM in 5 places (see if you can get all of the correct). Tyco Electronics maintains the private radio group, Cobham has the defense products, Micronetics has the RFID products, John Ocampo has the commercial products and Autoliv has the automotive products!

R&S Demos Femtocell Design Verification

At CTIA Wireless 2009, Rohde & Schwarz is demonstrating their LTE frequency division duplexing (FDD) testing capabilities based on the newest femtocell design from mimoOn. The compact test setup features the R&S® SMBV100A vector signal generator and the R&S® FSV signal analyzer to generate and analyze LTE signals that meet the newest specification.

The test setup on display at Rohde & Schwarz booth 6033 verifies that the femtocell reference design from mimoOn correctly operates according to the LTE specification that is about to be finalized. Accurate validation of the generated downlink signal of the mimoOn reference design is carried out with the R&S® FSV signal analyzer and the R&S® FSV-K100 downlink analysis option. The R&S® FSV’s innovative touch screen interface simplifies testing from the reference design to the final application of enhanced Node B (eNB) and Home eNB infrastructure.

Closing out Satellite 2009

Satellite 2009 was dubbed Solutions Start Here and lived up to its billing of offering a glimpse into the future of the satellite-enabled communications market and the solutions new technology will provide. The sessions covered enterprise, military, commercial, broadcast, government, and others. The conference and panel sessions covered many topics like Satellite broadband, WiMAX, IP networking, SatCom, hybrid networks, financial impacts, military applications, HD, Mobile TV, backhaul, etc.

I was impressed with the new RF/microwave technologies on display at the exhibition. Many companies were offering very high power, light weight amplifier and upconverter solutions from TWTs to SSPA. The filtering technology was just as impressive as the airways are getting more and more crowded with signals that need to be blocked out. And we cannot forget the antennas, feeds and motion controls at the end of the communication line that are also critical for optimal performance.

I am heading off to CTIA next week as we will put on the first ever RF/microwave Pavilion at CTIA Wireless 2009 in Las Vegas. Hope to see you there!

Satellite 2009

I attended the exhibition and one of the panel sessions yesterday. The show seems relatively busy which is a good sign these days. There were 2 interesting panel discussions I wanted to attend yesterday. One was on the capacity crunch and debated the different frequency bands as C-band seems to be slowing, Ku-band is growing and Ka-band is on the horizon. I was not able to make this one but made the one on the WiMAX and Satellite broadband debate - are they direct competition or complementary.

The panel was moderated by Claude Rousseau (NSR) and made up of Drew Caplan (SkyTerra), Amiee Chan (Norsat), Gary Hale (Cisco Systems), Laurent Thomasson (EADS) and Greg Wyler (O3b). They had done some polling of the industry and 59% thought WiMAX was a long term solution with only 11% thinking WiMAX was a direct threat to Satellite Broadband (but 69% thought is was an opportunity and threat). WiMAX seems to be a good solution for places that have no infrastructure for wireless backhaul and may not necessarily be a good mobile solution at this point. It seems like WiMAX and Satellite broadband hybrid systems that utilize the best one for each situation might be the answer in the long term.

The exhibition was fairly well attended and we visited many of the RF/microwave companies. We stopped by Cobham, Teledyne, Locus, Diamond, NEC, Actox, Wavecom, Tampa, FilTel, Microphase, K&L and Millitech. I saw some impressive amplifiers and upconverters that are very compact and high power. There are still some good TWT solutions but it seems like SSPAs with proprietary combining solutions are taking a big part of the business. Today we will finish off our visits and I will be doing a show wrap up of the whole event in the next couple of days.

Greenray Industries Debuts New TCXO

Stop by booth #1607 for more details.

CPI Satcom Showcases 100 watt Ku-band outdoor SSPA

CPI Satcom Division is featuring its 100 watt Ku-band outdoor SSPA at the SATELLITE 2009 Conference and Exhibition. This outdoor SSPA is the latest addition to the company’s extensive range of solid state amplifiers and is being touted by the company for its flexibility and easy maintainance. Frequency bands can be changed among X-, C- and Ku-band very quickly without rewiring and using only minor hand tools. Swapping out fans typically takes less time than it does to simply remove the cover on competing products. The ease of owning a CPI SSPA is enhanced by the company’s fifteen worldwide service centers and 24-hour telephone support.

Reliability is built-in to the CPI outdoor SSPA. In addition to the soft-fail RF feature found in most SSPAs, the CPI SSPA also provides redundant power supply modules and a microprocessor-controlled fault reporting system.

CPI’s satellite communications products are on display in booth 301 at the SATELLITE 2009 Conference and Exhibition.

At Satellite 09 Aeroflex Unveils Latest Payload Tester

At Satellite 2009 in Washington DC, Aeroflex announced the commercial availability of their Synthetic Multifunction Adaptable Reconfigurable Test Environment (SMART^E™) 5200 Series. This new hybrid synthetic Satellite Payload Test Environment includes hardware, software, test practices and support provides standard and customizable test programs tailored to the specific problems of testing (standard and customizable) high performance payloads, which consist of multiple channels, each with up to hundreds of connections between the test system and payload under test.

“The SMART^E 5200 replaces the STI1000C Satellite Payload Test System currently installed and in operation at customer sites worldwide,” according to Dr. Francesco Lupinetti, vice president and general manager, Aeroflex High Speed Test Solutions.

SMART^E 5200 is a highly integrated and reliable COTS-based solution. The core modules utilized in the SMART^E 5200 have been shipping in other SMART^E applications for approximately two years. Like the software and user interface, the core modules are production-grade and operationally proven in the field. When combined with proven accessories such as the Remote Calibration Unit (RCU), which allows TVAC testing of payloads with as many as 384 ports at an extended frequency of 40 GHz.

Aeroflex has more than ten years of experience in fielding synthetic test systems specifically configured for testing satellite payloads. Customers utilize the same systems for all stages of payload integration and test, including panel testing, reference performance testing of the full payload, testing in a thermal vacuum chamber and antenna-range testing in anechoic chambers.

Different satellite payloads may have many similarities, no two payloads are exactly alike and no two manufacturers have exactly the same test strategies and methodologies. When designing the SMART^E 5200, Aeroflex’s objective was to create a test environment solution with core capabilities that addresses the common aspects of satellite payload test and still remain flexible enough so that it can be easily customized to match the unique requirements of any given payload and associated customer. Each of the Satellite Payload Test Systems from Aeroflex share common core elements, but are customized with unique test aspects for each customer implementation.

The latest SMART^E Test Environments implement the core RF/microwave functions to be more modular in terms of the frequency ranges and power characteristics for the various applications. Satellite payloads operate at different frequencies and power levels depending upon the system application/mission to which they are applied. Frequency and power are two of the most basic cost drivers for microwave equipment, so the most cost-efficient solution is a test system that optimally and dynamically matches the range of frequency and power characteristics of the modules to be tested.

Together with full diagnostic capabilities, calibration and NIST traceable standards, Aeroflex supplies a standard library of common tests with each Satellite Payload Test Environment, including: Payload Control, Multi Carrier, Gain Transfer/ALC, Noise Power Ratio, Noise Figure, Frequency Conversion, Amplitude Linearity, Group Delay/Phase vs. Frequency, Passive Intermodulation, and many more.

Satellite 2009 in DC

I am heading out to the Satellite 2009 show in Washington DC tomorrow morning to meet with the RF/microwave companies there. I hope to recruit some good material for our August Satellite and mmWave issue and perhaps our October Gov't and Military issue. It should be an interesting trip before heading out next week to Vegas for CTIA.

If anyone else is attending and wants to meet for coffee (or a drink), drop me a line.

Super Broadband Devices

There seems to be a trend these days in designing very broadband devices that will operate over many communications bands so a single device can be used in many applications. Triquint recently developed their PowerBand family of amplifiers that feature high power (10-50 W) and good efficiency (typically 45-50%) over a wide band from 500 MHz to 3 GHz with a single device. They state that 2 to 4 Powerband devices can replace a typical line up of 6 to 12 devices. The have plans to extend the range of these devices to 6 GHz and improve the power levels by leveraging LDMOS and GaN technology (I believe the current devices are GaAs based).


Yesterday Analog Devices released a 14 bit RF digital to analog converter (DAC) that uses direct digital synthesis to convert signals from DC to 3.6 GHz. One device can handle up to 72 QAM channels with sample rates up to 2500 MPSP which is very impressive performance. It will enable wireless communications designers to use a single transmit-DAC architecture for multiple communications standards while eliminating an off-chip mixer and low-pass filter.


These 2 devices can pretty much make up a complete transmit chain that operates at about any frequency currently used for communications systems (maybe they can partner up). What other very broadband devices have you seen recently developed?

Treating Tumors with Microwave Ablation

More news from the "microwaves in applied science" front. A new minimally-invasive option for treating liver tumors, called microwave ablation, is now available at UC San Diego Medical Center and Moores UCSD Cancer Center, the only hospitals in the region to offer this technology to patients. “Microwave ablation causes the tumor to be quickly and precisely removed. If necessary, multiple tumors can be treated at the same time,” said Marquis Hart, MD, transplant surgeon at UC San Diego Medical Center. “This method appears to be more efficient than other ablation techniques which translates to better tumor destruction and less time for the patient under general anesthesia.”

To perform the procedure, Hart accesses the tumor through the skin, or through a small laparoscopic port or open incision. With ultrasound guidance or a computed tomography (CT) scan, the tumor is located and then pierced with a thin antenna which emits microwaves. This energy spins the water molecules in the tumor producing friction which causes heat. Temperatures above 60 degrees Celsius (140 degrees Fahrenheit) cause cellular death, usually within 10 minutes.

In addition to liver disease, microwave ablation has promising potential in the treatment of lung, kidney, and bone cancer. Studies using microwave or radio frequency ablation for the treatment of cancer has been in the works for several years. Apparently the studies were sucessful and the technology is going mainstream.

The Nano Radio

This is not totally new news but a recent article in Scientific American has called some attention to it as researchers have built the world's tiniest radio out of a carbon nanotube. The tiny nanotube is placed between two electrodes and combines the roles of the major electrical components in a radio, including the tuner and amplifier. It can tune in to a radio signal and play the audio through an external speaker.

The nanotube radio works differently than a conventional radio that has an antenna, tuner, amplifier, and demodulator. A single carbon nanotube can tune in to a radio signal, amplify it, and demodulate it to get the audio encoded on the carrier radio wave. The nanotube starts vibrating in tune with a radio signal if the signal is at the same frequency as the nanotube’s natural resonance frequency. This can be controlled by the electric field that is placed on the nanotube so it can be tuned to the proper frequency. The first song played was appropriately Good Vibrations by the Beach Boys.

At the AMTA conference last year I saw some research on using nanotubes as antennas for miniature radios but the initial work showed they were not able to make them work very well at RF frequencies.

ADS 2009 Targets HF/HS Co-Design

Agilent has just recently announced the release of ADS 2009, targeting the high-frequency & high speed front end co-design (IC/Package/Board) challenges discussed in February's MWJ lead story - "The Dawn of Nano-scale Technology". The complexity of these designs require tight integration between the the front-end (simulation & verification) and back-end (Cadence or Mentor Graphics)tools. For example, 4G LTE phones must also have Bluetooth, Wifi and MIMO capabilities which means multi-antennas operating over multi-frequency bands while remaining backward compatible with 3G and 2G modes. In turn, high frequency and high speed components will need to fit into smaller volumes and closer proximity with greater undesired interactions. With smart phones be among the few markets in commercial electronics expected to grow in 2009, the pressure to acheive design success is great. Since costs & delays must be kept low, multiple available technologies are being integrated onto the PCB instead of designing all onto an IC.


One of the key components in ADS 2009 to address IC/Package/Board co-design is the new interoperability with Cadence and Mentor backend design platforms, allowing engineers and designers to import:

• Cadence Allegro PCB, Advanced Package Designer (APD) and SIP physical
design data for co-designing with active components
• Design Rule Check (DRC) results from Cadence Assura, Mentor Calibre or
Triquint MailDRC for viewing and correcting within ADS cost-effective
layout environment.

Agilent has also extended ADS 2009 model support to include X-parameters, a form of "black-box" component representation based on non-linear measurements (using the Agilent PNA, non-linear network analyzer). Measured x-parameters can now be used directly in ADS simulation to accurately represent off-the-shelf components.New support for 3D electromagnetic parameterized components representing metal shields,
antenna radomes, absorbers, packages, interconnects, finite dielectric
substrates and wire bonds has also been added.

World’s Smallest Bluetooth and Wi-Fi Solution

I came across this recently launched product from World Mobile Congress as CSR has worked with Murata and released the CSR9000 which they claim is the world’s smallest Bluetooth and Wi-Fi solution and supports a long list of connectivity technologies: Bluetooth, Bluetooth low energy, Wi-Fi (IEEE 802.11abgn) and FM receive and transmit.

This is achieved by a combination of CSR’s ‘Smart Integration’ approach to silicon design as well as being as Wafer Level Chip Scale Packaging (WLCSP) technology. WLCSP achieves the smallest PCB footprint and is the packaging technology of choice for high volume, small form factor devices such as mobile handsets.

This is another example of our Feb. theme as we trend towards nano-scale SoP technology and the industry drives down size and cost. This product supports Bluetooth low energy which seems to be opening up new applications such as embedding Bluetooth in shoes, watches, etc. What applications do you envision for this new version of Bluetooth?

Fifth Annual Device Packaging Conference

The Fifth Annual Device Packaging Conference (DPC2009) will be held in Scottsdale, Arizona, on March 9-12, 2009. It is an international event organized by the International Microelectronics And Packaging Society (IMAPS). The conference provides a focused forum on the latest technological developments in 6 topic areas related to microelectronic packaging: 3D Packaging; Flip Chip; Wafer Level Packaging; MEMS; BioMedical Devices; and Power LED Devices. While the majority of technical sessions seem to be focused on fabrication, reliability and thermal issues (i.e. Impact of Underfill Design on Package Reliability), advanced packaging technology certainly impacts multi-chip manufacturers. A couple of talks from the technical sessions caught my eye, including:

Tunable Millimeter-Wave Device Based on Waveguide-Packaged MEMS

Compact Square Patch Antenna for Mobile Application

In the poster sessions, look for:

RF and Thermal Analysis of Packaged TGA4046 Q Band Amplifier

Design of Tunable Filter Structures using Multilayer Low Temperature Cofired Ceramics (LTCC)

A Unique Process for Hermetic Wafer Level Packaging

RF SoP Co-design

This month's lead story in Microwave Journal looks at the state of System on Package technology as package device features move to the nano-scale. With such high density, the co-design of RF System on Package (SoP) is an evolving concern among multi-chip module manufacturers and the EDA companies that support this complex technology. Our editors posed a number of related questions to AWR, Agilent and Mentor Graphics on co-design, simulation and design flows for multi-chip modules and advanced packaging. The following MWJ exclusives take a look at this evolution.

RFMD, Skyworks and TriQuint Continue to Control GaAs Market

Growing up in the GaAs market in the 80's, I like to follow how the market is doing. In its latest GaAs report, Strategy Analytics states that RFMD, Skyworks and TriQuint lead the overall GaAs device market which grew 9% year-on-year in 2008, with early estimates showing that RFMD, Skyworks and TriQuint further consolidated their leadership of the GaAs device industry, accounting for up to 59% of total GaAs industry revenues. Merchant demand for GaAs devices continues to be centered upon MMIC-based products targeted at the wireless sector and this drove GaAs device industry revenues up to $3.9 billion in 2008.

Asif Anwar at Strategy Analytics noted that 2008 was a very good year, but growth in the GaAs industry hit a wall in the fourth quarter of 2008 and 2009 will see industry revenues decline by five to six percent. However, he believes 2009 also presents an opportunity for the market leaders to squeeze out their competition, provided they can successfully leverage existing relationships while continuing to tap into adjacent markets and emerging opportunities.

Other conclusions include:

While TriQuint and Skyworks closed the gap, RFMD maintained its standing as the world’s largest supplier of GaAs-based RF components

Collectively the top ten GaAs device manufacturers—including Avago Technologies, M/A-COM and Mitsubishi Electric—accounted for up to 82% of the overall market.

2009 GSMA Mobile World Congress: Gauging the Market

Our international editor, Richard Mumford, attended Mobile World Congress last week. According to the official figures, the organisers claim more than 47,000 visitors (including delegates, exhibitors, contractors and media) from 189 countries attended the four-day conference and exhibition at the Fira de Barcelona from 16 to 19 February, which compares with 55,000 visitors in 2008. The number of exhibiting companies remained the same at 1,300.

The event has a longstanding reputation for being a dynamic showcase for the mobile industry, a hotspot for innovation and a springboard for new technologies, but was that still the case at a time when market confidence and perception are key factors? Richard's perception was that although the event may have lacked the flamboyance of previous years and that the mood was more subdued there was no denying the continued determination to innovate and benefit from a market where the potential to profit from the right product at the right time remains substantial.

ZigBee and Now RuBee!

The Institute of Electrical and Electronics Engineers (IEEE) has approved RuBee®, a long-wavelength, packet-based, magnetic transceiver protocol, as a new international standard designated IEEE 1902.1. RuBee overcomes many of the problems seen with RFID and other wireless asset visibility solutions in harsh environments through its ability to work on steel and in liquids. RuBee tags and antennas are volumetric in harsh environments, not line-of-sight as is typically the case with other wireless technologies (and bar codes). RuBee tags work over a range of 1 to 50 feet depending on antenna configuration, and can be powered by a single coin-size lithium battery with battery life from 5 to 15 years. RuBee tags and systems can easily be combined with sensors, buttons, displays, and LEDs.

IEEE 1902.1 has been used to ensure the visibility and safety of government owned firearms, high valued evidence, military weapons, patient visibility and optimal patient flow in hospitals, hospital disposable and implantable inventories, livestock, disaster recovery equipment and safety systems, mission-critical tools, aircraft maintenance tools, and many other categories of highly valued goods and services. RuBee wireless asset visibility networks seem to be cost-competitive with other wireless networking solutions, including RFID so they could have a good future for these harsh environment applications.

GSMA Mobile World Congress Serves Up Latest Technology

You will get to digest fully what was on the menu at the GSMA Mobile World Congress in Barcelona this week in my Wrap-up article that will be posted when the show comes to a close. For now though I can give you a tapas selection of the technology that has been whetting the appetites of the attendees this week.

To start, building on the past few years LTE is the key technology being discussed and although opinions vary as to the timescale for deployment it is a focus of activity and investment. The buzz though surrounds 4G TD-LTE, a time division duplex (TDD) version of LTE, which is the next evolution for TD-SCDMA. Although driven by the Chinese market this technology is envisaged as having global applications.

Femtocells came under the spotlight too in a special Femtozone featuring a programme highlighting research, business cases etc. If this tapas has given you food for thought, look out for my full report soon.

Verizon 4G LTE Service Coming Soon!

Speed, speed and more speed -that is what I want. Verizon has answered this demand by announcing it will begin testing 4G wireless service using LTE this year and launch it in at least 25 to 30 markets in the U.S. in 2010. This is based on their roll-out of EV-DO, assuming they will get to about the same level in the first year of deploying LTE. Verizon will continue to build out the 4G wireless network and expects to blanket the continental U.S. and Hawaii with the new wireless network by 2015.

The new network will use the 700 MHz wireless spectrum that Verizon acquired in the Federal Communications Commission's auction last year. The company announced in 2007 that it had planned to use LTE for this market which will be available after the US broadcasters finish transitioning to digital TV signals. Several GSM operators around the world have also announced plans to use LTE which means that Verizon 4G wireless subscribers might eventually be able to roam globally.

Verizon has been testing the service in several areas in the U.S. including Minneapolis, Columbus, Ohio, and northern New Jersey. It's also been working with Vodafone (their co-parent) and China Mobile to test deployments in other parts of the world, including Budapest, Hungary, Dusseldorf, Germany, and Madrid. In its initial trials, Verizon says it has demonstrated peak download speeds of around 50- 60 Mbps. But average download speeds are likely to be lower since the wireless spectrum is a shared. The network will certainly be much faster than the average speed of Verizon's 3G EV-DO service which typically gets up to 400-700 Kbps.

Moblie World Congress 2009 Kicks Off!

So what's hot this year at Mobile World Congress. It seems a little subdued because of the projections for handsets to decline by about 10% this year but there is always the next big thing coming down the road in technology. There seems to be a fair amount of green technology - mostly solar powered devices, etc. Android has picked up some support from a few applications providers and RFID/payment technologies are taking hold in handsets.

WiMAX was hot last year but this is the year of LTE (even as WiMAX is actually rolling out some implementations). With such a large installed base of infrastructure, LTE will come on strong even though WiMAX has a lead as far as timing is concerned. And Agilent came out strong at the show yesterday with some 9 or 10 news releases. Several of them surrounded LTE test solutions such as a complete end-to-end analysis and troubleshooting solution for LTE networks. The Signaling Analyzer Real Time (SART) for LTE provides comprehensive monitoring and network diagnostics by interpreting, correlating and analyzing protocol signaling messages produced by multiple network technologies at mobile network interfaces. They also announced the first LTE real-time signal generation and channel emulation solution for base station test, new commercial test products for TD-LTE: PC-based software for creating standards-based TD-LTE signals and vector signal analysis (VSA) software with TD-LTE modulation analysis capability plus a MIMO connectivity option and network conformance testing system for mobile WiMAX.

Agilent and Anite plc also announced they will demonstrate 3GPP LTE interoperability showing end-to-end streaming video with LTE UE devices from Signalion and Blue Wonder Communications plus Agilent will demonstrate LTE EVM, Tx power measurements and downlink transmit diversity for mobile device test using the E6620 wireless communications test set at Mobile World Congress so drop by to see them.

That is a large dose of test equipment! What have you seen at Mobile World Congress???

mmWave Scanners make the News

Doing a little business traveling this week and so I'm being treated to a copy of USA Today outside my hotel room door and I have to say it's nice to see microwave (in this case millimeter-wave) technology making the front page of a mainstream newspaper. The article in mention "Scanners replace detectors in tryout" refers to a new scanning technology being tested out by the Transportation Security Administration at the Tulsa International Airport.

An experimental program that begins today will test whether the $170,000 body scanners could replace $10,000 metal detectors that have screened airline passengers since 1973. The scanners should be capable of detecting non-metallic weapons such as plastic and liquid explosives, which the TSA considers a major threat. The scanners bounce harmless "millimeter waves" off passengers' bodies and use no radiation. The Journal had reported such technology several times over the past 2 years (see our cover story from October 2007 (A Radar-based Concealed Threat Detector) and our Executive Interview with Mark Hebeisen from Endwave Corp. (Endwave supplies the millimter-wave front-end that is part of the system from L3 Communications)


Airline passengers will skip metal detectors and instead be screened by body scanning machines that look through clothing for hidden weapons. Critics of the technology raise privacy concerns because the passenger's images reveal outlines of private body parts (these will be blurred for machine operators).Security analyst Bruce Schneier, a frequent critic of the TSA, said the scanners should improve security but warned that they take longer than metal detectors — 30 seconds vs. about 15 seconds per passenger. "There will be pressure to do the screening faster, which will be sloppier," Schneier said.


Airports in San Francisco, Las Vegas, Miami, Albuquerque and Salt Lake City will join the test in the next two months, TSA spokesman Christopher White said. Hopefully, the trials will be a great succuss. I would love to be able to travel again without having to undress for security.

Stimulus Package Opens Grant Funding for Wireless Broadband

The final passing of the American Recovery and Reinvestment Bill by Congress last week calls for over $6 billion in grants for the expansion of broadband areas across America. This funding will provide continued progress in the deployment and adoption of broadband technology that is vital to ensuring that the United States will remain competitive worldwide. As a platform capable of providing access everywhere, wireless broadband will be essential in bringing innovation and helping reach the Obama Administration’s goal of achieving universal broadband connectivity.

Commercial entities are clearly eligible for direct grants from the National Telecommunications and Information Administration (NTIA), go to http://www.ntia.doc.gov/. Commercial wireless hardware vendors and network providers stand ready to move forward with plans to bring wireless broadband to rural and underserved areas. Having direct access to grant funding will allow them to do so in a timely manner, helping create jobs fast, enable productivity, and should help jump-start our economy.

U of C, Berkeley Research Leads to Radio in Bug

Last month (January 28th), The University of California, Berkeley succeeded in controlling a live rhinoceros beetle by radio. A video of the experiment was previewed at the MEMS 2009 academic conference taking place in Sorrento, Italy. In the experiment, radio signals were sent to six electrodes attached to various locations of the beetles brain and muscles, thus allowing university researchers to control the movement of the beetle’s wings and some other parts. They equipped the beetle with a module incorporating a circuit to send signals to the electrodes, wireless circuit, microcontroller and battery. Controlling the movements of an insect is not a first for the university. This was the first time using a radio control system.



Rhinoceros beetles with a weight of up to 3g were used in this experiment because they can carry the controlling module (weighing about 1.3g) on their backs. And another reason is that they look cool, according to the university.

So what’s the point of this exercise? Considering that the Defense Advanced Research Projects Agency (DARPA) is funding the research, military purposes are a likely contender. Commenting on this point, the university said that the technology can also be utilized for peaceful purposes. For instance, the radio-controlled beetle can be useful in places that are too narrow or dangerous for a human to enter and for many other purposes.

For that use, the university is planning to mount sensors including a camera on a beetle in the future. With the sensors, rhinoceros beetles will be able to work as surveillance robots in place of humans. As they can carry a weight of 3g, 1.7g of sensors, in addition to the 1.3g of the current module, can be mounted.

However, the ultimate goal of this research goes beyond just incorporating sensors. Beetles are already equipped with "sensors," such as their own eyes. In addition, they have a system to derive energy from food. So, the university is aiming to make the most of insects' own sensors while using their energy system as batteries.

I think we are on a slippery slope with this one. Attack of the Rhino Beetle? I might have trouble sleeping tonight.

COMSYS Mobile Demonstrates Multimode Data Handover

by MWJ European Editor, Richard Mumford

Comsys Communication & Signal Processing Ltd will be demonstrating multimode data handover between Mobile WiMAX and cellular networks as well as a customer commercial handset running the company’s Mobile WiMAX/EDGE solution in Hall 2, Stand B73. The multimode data handover between Mobile WiMAX and GSM-EDGE networks will demonstrate how service continuity is achieved over Comsys Mobile’s ComMAX™ CM1100 mobile WiMAX baseband processor in conjunction with any third-party legacy cellular baseband, or independently with the CM1125 WiMAX/EDGE processor, thus providing a multimode solution that enables the user to always be connected.

“Our booth at Mobile World Congress will be a must-see attraction for industry stakeholders in the WiMAX community,” commented Ehud Reshef, director WiMAX product marketing at Comsys Mobile. “Visitors will be able to see a range of mobile WiMAX devices, supporting WiMAX and GSM/EDGE and incorporating Comsys Mobile’s unique baseband processors. Integrating them in customer devices highlights the maturity and uniqueness of our product offering, and demonstrates in an extremely tangible way the viability of WiMAX/EDGE service continuity.”

SA Predicts Rapid WiMAX Growth in Asia

Strategy Analytics said the predict that consumer WiMAX subscriptions in the developing countries of Asia will grow from a few thousand now to almost 27 million by 2013. Their research predicts that the strongest growth will come outside the major cities of Asia. Subscriptions in villages and small towns are forecast to grow at almost 300% per year, three times the rate of major cities. Government policies aimed at closing the rural-urban “digital divide” are one reason for this rapid growth, but historic lack of broadband alternatives is at least as strong a factor.

“Big cities are the obvious place to start,” says Tom Elliott, Director of EMCS and the report’s principal author. “They have high concentrations of Internet-savvy young people. But they also have a lot of competition. The real WiMAX opportunity is outside of large cities.” Packet One, a WiMAX provider in Malaysia, appears to be following such a strategy. Its first deployments in were in Kuala Lumpur, but it has moved rapidly to launch in Johor and Penang, two less densely populated states outside the capital region.


“Incumbent broadband suppliers and cellular operators offering High-Speed Packet Access, HSPA, alternatives are formidable competitors in the big cities,” notes David Kerr, head of Strategy Analytics Global Wireless Practice. “There’s simply a lot more un-served demand in market towns and provincial business centers.”

WiMAX seems to be really catching on in areas that currently don't have much infrastructure and deployments are growing. LTE better hurry up!

Google Starts "White Spaces" Group

It was recently announced that Google is teaming up with several technology companies, including Comsearch, Dell, HP, Microsoft, Motorola and Neustar, to form a new coalition called the White Spaces Database Group, which will provide and compile into a database technical specifications for devices that will use white space spectrum.

White spaces are unused slivers of spectrum in the 700 MHz band that sit between broadcast TV channels. Google and others successfully lobbied the FCC last year to open up that spectrum for unlicensed use so that new wireless devices could access that spectrum. In its ruling in November, the FCC said that devices using a combination of geolocation technology and spectrum-sensing technology could be approved for unlicensed white space use. Before sending or receiving data, devices will be required to access this database to determine available channels. And the device will not transmit in channels that are already known to be in use.

TV broadcasters and wireless microphone companies have long opposed the use of this spectrum fearing it will interfere with their services but Google believes that using geolocation technology used along with spectrum sensing technologies will offer complete protection to licensed signals from harmful interference. Do you think the TV broadcasters and wireless microphone companies have a legitimate complaint?

Garmin Gets into the Smartphone Game

Building up to Mobile World Congress (MWC) in Barcelona next week, several well known companies have been hinting about new smartphones offerings, each with a specific use case and no shortage of challenges to overcome.

Taiwanese PDA and computer-maker AsusTek Computer and personal navigation device (PND) company Garmin formally announced that the two companies will introduce a jointly branded line of smartphones, called Garmin-Asus nuvifone, the first of which will debut at MWC. Jonney Shih Chairmen of Asustek said that the Garmin-Asus phone will likely launch worldwide by next year and that the G60 will be announced at the Mobile World Congress in Barcelona. The MWC is already pegged to be the launch pad for both Dell and Acer’s additions to the smartphone family. Garmin-Asus will also compete against popular devices such as the iPhone and T-Mobile's G1 Android-based handset by specializing in location-based services (LBS), executives from both companies said.

The location-centric smartphone could hypothetically take the place of a traditional PND and is optimized for communication and navigation. The first nuvifone also will feature Ciao, a social networking application that combines location-based social networks in the device and the same turn-by-turn, voice-prompted navigation as Garmin’s PNDs. It comes preloaded with maps and points of interest that are searchable by category, establishment name or destination.

In expanding beyond its core competency, Garmin will be hard-pressed to find distribution channels or carrier partners, said Neil Mawston, director of global wireless practice for Strategy Analytics. The brand is not associated with mobile devices, and it already attempted its first nuvifone device back in early 2008 with very little uptake. Teaming with Asus is a step in the right direction, but Mawston said they are far from success.

“Garmin is one of the world’s biggest players in [PND] and has a good reputation,” Mawston said. “If they were to come along with a good set of apps and a store that goes with it and prove to carriers there is a potential to grow revenue through new services like social location — if they could prove there is potential to raise ARPU — there is definitely potential to work with big players. But at the present time, you struggle to see how they are standing apart from the competition. They don’t have the brand strength, the brand isn’t exciting, and the services don’t stand out — they are good rather than great.”

Personal navigation, along with gaming devices, is a segment that many analysts believe would make prime candidates for app-specific mobile Internet devices (MIDs), pocketable computers optimized around mobile Web browsing. But the segment is still a few years off as vendors focus on the netbook and smartphone category.

College Students Chat with Space Station Using Their Radio

Four Toronto college students from The Humber College have accomplished a technological feat by making contact with the International Space Station last week using a radio system they designed and built themselves. It was a scheduled event so they did not just call them out of the blue.

The project got off the ground about a year ago as the students looked for a way to apply knowledge gained from their radio communication courses. The first message got no response, but a second attempt reached astronaut Sandra Magnus. They had a 10-minute window to talk to her, during which they asked some technical questions and passed on a few other questions from contest winners at the school. One student asked how well the International Space Station is protected from debris, while another wanted to know how it feels to see Earth from space.

While school contacts with the space station are routinely made through the Amateur Radio on the International Space Station program, many of those contacts are made using a traditional ham radio. “It's an incredible feat of undertaking and technology, and I'd just like to say I'm really, really proud of this team,” said Humber instructor Mark Rector.

So on the next revolution around the Earth, dial up the power on your ham radio and see if you can reach them!
