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.

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.
