GaN and Si Based Technologies Invading GaAs Territory
Since writing this article, additional news items have been released to support this story as we will continue to follow it. About a week ago, Skyworks announced a cost-effective CMOS front-end module (FEM) for GPRS handsets. Skyworks’ new device offers handset OEMs architectures and high-performance solutions for entry-level phones in a small 5 x 6 mm package. By eliminating the need to optimize matching between the amplifier and the switch, this module helps accelerate customers’ time-to-market relative to other more traditional architectures, and simplifies the supply chain for high-volume, cost-sensitive phones. I believe this device is a continuation of the work done by Axiom Microdevices that they acquired about a year ago. This keeps them in the cellular handset market with both technologies.
And now Engalco has released a new report on how GaN and SiGe are making in roads into traditional GaAs markets. According to their market report – MMICs2 – the compound semiconductor MMIC market to 2015 – GaAs MMICs will remain important, while GaN and SiGe MMICs will progressively invade these markets. Although the overall worldwide total markets are forecasted to reach $6.26 B in 2015, this total continues to be dominated by the commodity markets of cell phones (over $3 B) and both intelligent cruise control and mobile WiMAX ($1.2 B each). After these end-users have been considered, the remaining market segments of defense, ISM, microwave radio, millimeter-wave radio, SATCOM and SATNAV all come in with much lower market shares. Of these, microwave radio accounts for a market worth around $280 M in 2015; millimeter-wave radio exhibits exceptionally high (double-digit) growth to reach $420 M in the same year. The latter market is driven by the exploding capacity requirements of multi-Gbit links.
In the defense segment the report says North America (principally the US) leads, but both Europe and Asia (especially) are increasingly important. The report indicates how both GaN- and SiGe-based MMICs will progressively invade many market segments. The utility of GaN MMICs for high-power/high-efficiency RF amplification is becoming well known; the application will also be extended to other functions in RF modules. SiGe-based MMICs are already being implemented in low-power signal processing roles, mainly in receivers and switches.

Anadigics Stock Price Jumps as Trading Opens
Newton said he expects the company to be taking a bigger share of the market as the year goes on. He said that should help the company's earnings outstrip Wall Street forecasts in the near term. Further out, the company's quarterly revenue of about $80 million to $90 million should pick up to $160 million to $200 million, Newton said. Anadigics shares rose 25 cents, or 6.2 percent, to $4.25 in premarket trading.

Low Cost 2.4 GHz Weatherproof Antennas Targets M2M Apps

Since Pat has brought up the topic of antennas with his blog about this component's "five minutes of fame" sharing the stage with Steve Jobs as the Apple founder introduced the new 4G iPhone, I thought I would share the following product release that came across my desk today as well. After all, any RF/microwave device targeting Smart grid applications has as much of a cool factor as any in the latest smartphone. Well, maybe not. But helping to save the planet by being green gets my seal of approval.
Pulse, a Technitrol Company (NYSE: TNL), a manufacturer of electronic components and subassembly design and manufacturing, introduces its new low cost, weatherproof antennas for 2.4 GHz devices used in industrial, smart grid metering, security, broadband access, and other machine-to-machine(M2M) applications. These robust, high-efficiency, compact antennas meet Bluetooth, WLAN, WiFi, IEEE 802.11b/g, ZigBee IEEE 802.15.4, and 2.4 GHz ISM band system standards.
Pulse's W5001, W5010, and W5011 antennas function in ruggedized conditions, offering IP65 water ingress protection in accordance with international standard IEC 60529, UV protection, and the ability to withstand 100 mph wind loading. They have a maximum gain of 1.5 dBi in the 2,400 to 2,500 MHz range, an efficiency of 70%, and an operating temperature range of -40°C to 85°C. The antennas have a small footprint and low profile, measuring only 128mm x 18mm.
Pulse's W5001, W5010, and W5011 antennas are available in three SMA connector configurations: fixed right angle, straight SMA, and RP-SMA. They are packaged in quantities of 20 pieces per bag.

Cell Phone Market Forecast by Forward Concepts
Forward Concepts has published an in-depth study of the worldwide cellphone market and the associated ecosystem of subscribers, operators and technologies. Some of the key findings from the study are:
- Worldwide unit cellphone shipments fell by 0.5% in 2009, as the entire electronics market was muted by global economic conditions. They are forecasting a much healthier 11% growth in 2010 to 1.4 billion units.
- Unit growth varies markedly by region, with China's market forecast to grow by 23% in 2010, while Western Europe's will grow by a more sedate 4%.
- India will lead in subscriber growth this year, growing an estimated 30% compared to China's 7%.
- Apple exhibited the greatest unit growth of all cellphone vendors in 2009, with an 83% growth. Following Apple was Tianyu with 68%, NEC with 46%, RIM with 44%, Inventec with 23%, LGE with 21%, TCL and Huawei each with 17%, Samsung with 16% and HTC with 10%. Of course, the lesser-known companies began with smaller shipment bases.
- In smartphones, ZTE had the highest 2009 unit growth, at 160%, with revenues of $400 million in that category, followed by Apple's 83% growth, but with much higher revenues of $13.8 billion.
- Smartphones, such as those by RIM, Apple and HTC get the most press, but they only constitute 13% of the unit cellphone market, while so-called feature phones make up 25%.
- Budget cellphones, popular in India, China and Africa presently make up 23% of the market, while mid-range units account for the largest market, at 39%. We forecast that the budget market will flatten as their replacements will lead to better growth of mid-range models.

TriQuint and Avago Supply RF FEMs for New HTC Evo

These components are the typical RF platform for HTC designs of this type but new here is the 4G capability supplied by the Sequans SQN210 WiMAX chip that supports mobile WiMAX baseband and three frequency bands: 2.3-2.4, 2.5-2.7, 3.3-3.8 GHz. This includes a low-complexity MIMO algorithm on the downlink and 2Tx on the uplink for 2Tx diversity and optional full 2×2 uplink MIMO. This type of integration is impressive and they will offer LTE solutions also.
Is it too early for a 4G phone with such limited infrastructure in place? What do you think??Friday, June 4, 2010
Surprises on the MTTS 2010 IMS Show Floor
You never know what type of products or companies you will run into at the IMS show. I came across Phillip Jobson who has developed the "pocket radar." It is a palm sized speed radar unit that provide accurate real-time speed measurements of moving objects using 24 GHz radar. It is suitable for things like baseball, racing soccer, tennis, track, etc. It is accurate to +/- 1 mph and measures speeds from 7 to 375 mph. It sells for about $200.What did you see at the show that was unique or surprising?

MTTS 2010 IMS Attendance Up Over Last Year
- The exhibit floor showcased a total of 556 companies & 892 booths representing 40 countries
- Technical registration numbers totaled 2,793 participants
- Exhibit-only registration numbers indicate 2,687 participants
- A total of 858 technical papers were submitted at this year’s conference, representing countries from around the world
The exhibition seems very lively and positive according to most people on the floor. What did you think?
MTTS 2010 IMS Exhibition Opens
The MTTS 2010 IMS exhibition was very lively as it opened yesterday in Anaheim. The traffic was robust and the was mood upbeat as the industry seems to have shaken off the recession. There seemed to be a wide variety of new amplifiers available with very high linearity and efficiency. The improvements in modeling and matching have resulted in some really nice designs. There were also several suppliers with cellular band LNAs that have less than .5 dB noise figures. The larger component manufacturers seem to be filling out their portfolios to meet a wider variety of needs to satisfy as much of the block diagram as they can with their products. Several of the component manufacturers are also offering SMT filters as the frequency bands of many applications are now inferring with each other in smart device applications.There is certainly high interest in smart grid/metering market along with the wireless consumer applications which are projected to grow rapidly. Also the higher frequency backhaul point to point radio market seems to be a prime target for component offerings. Strategy Analytics today released a report that shipments of short range gigabit radios for display links, HDMI cable replacement, streaming multimedia and last hundred meter Internet access will reach tens of millions of units per year in 2014 (short-range 60 GHz radio, 802.11n 4 x n / 802.11ac, inductive coupling, and proprietary ISM-band approaches such as WHDI).

Mike Cobb - Friend, Mentor
Mike was my manager for a brief period of two years, in which time he supported me in my job with solid technical guidance, sage advice, and good humor. I am sure that my experience with Mike was far from unique. Most everyone who worked with Mike remember his unwavering skills as an engineer, common sense approach to problem solving and positive attitude. Born in North Carolina in 1951, Mike’s southern accent was a rarity among the Boston natives at Raytheon and yet he addressed any and all northeast elitist attitudes with a firm engineering grasp and a touch of southern charm.
Mike received the B.S. degree in physics from East Carolina University in 1978 and the M.S. degree in microwave engineering from the University of Massachusetts under the UMASS/Raytheon MSEE Degree program. He began working at Raytheon in 1980, where he performed dc and RF characterization measurements of pulsed X-band GaAs IMPATT diodes and circuits, transitioning into a MMIC design and simulation role.
I’ll remember consulting with Mike many times in his office. I can remember looking past him and up toward the family picture he kept tacked to the cork board over his desk. In it, Mike stands on a dock with his young son and daughter, hooking bait onto their fishing lines. I always found it reassuring to be working for someone with such a strong and loving connection to those in his care.
Last summer Mike learned that he had a lung cancer that had spread to his nervous system with no hope for a cure. Mike was 58. His goal was to live long enough to see his 1st grand kid. He made it, but just barely. His cancer spread aggressively to his meninges, and he went downhill very fast, within days. He passed away peacefully this Monday at his daughter's house in Providence. Mike got to hold his brand new granddaughter, Clara Michelle, before he passed.
Mike – your passing truly saddens all of us who knew you and had the pleasure to work with you.
Services will be in Providence, on Sunday at 3pm, with visitation from 1-3pm, at Monahan, Drabble, and Sherman Funeral Home, 230 Waterman St., Providence, RI. A private burial for family will take place on Monday morning.
Instead of flowers, we are asking for donations in memory of Mike towards thoracic oncology research:

Raytheon Microwave System to Prevent Frost in Vineyards
Tempwave’s Microwave Approach
Tempwave is Raytheon’s patent-pending system that uses low-level microwave radiant heat to prevent frost damage to crops. The system directly transmits microwave energy from towers located in an orchard or vineyard to crops without heating the intervening air. Among the system’s many advantages, Tempwave uses no water; emits no smoke, unlike fuel heaters; and operates silently, unlike noisy wind machines used for frost protection.
Mission Innovation is charged with exploring and applying Raytheon technical expertise to address global challenges outside Raytheon’s traditional core business interests in defense, homeland security and other government markets.
Do you see any other potential uses for this technology?

Big M&A Activity as MTTS 2010 IMS Nears
Next Comtech Telecommunications acquired CPI International for about $475 M. Fred Kornberg, President and CEO of Comtech said the acquisition is a significant step in their strategy of developing a one-stop shopping approach for RF microwave products. The transition is expected to be seamless as they will keep all of CPI's agreements and executive staff in place.
Finally on the merger front, M/A-COM and Mimix agreed to merge last week which was not unexpected as they were both owned by John Ocampo/GaAs labs. I blogged about this previously so I wont' go into any details here.
With 3 big mergers there were also 3 big partnerships/market entries announced recently in the microwave world. The first partnership was IBM teamed up with Peregrine to run their UltraCMOS SOS process on their 8 inch, 180 nm line giving Peregrine a large capacity, low cost chip fab. They plan to utilize future processes using 130 and 90 nm processes for higher performance.
Next Freescale surprised me by announcing they are entering the GaAs MMIC market with 4 new devices. They have always been such a force in the high power LDMOS market that I never envisioned them entering into the GaAs market but I think it is a good move. These products include both PHEMT and HBT products and seem to mostly target the base station market so it expands their portfolio of products in that area.
And finally, EADS and Alcatel announced they are teaming up develop a mobile solution designed specifically to address the public safety market in the United States. The solution, based on LTE and on the public safety Project 25 (P25) standards and will provide mission-critical communications to state and local public safety organizations (fire, police and ambulance departments). The solution is an IP based system that will be interoperable with other communication systems.
This is the busiest pre-MTTS/IMS show news year I have ever seen with a lot of business activity and products announcements. Visit our show news page for up to date information prior to, during and after the show and here is a sneak peak at a May online article on Microwave M&A from a business stand point.

ABI Handset Market Estimates for 1Q-2010
According to ABI Research, handset shipments globally for 1Q-2010 powered ahead to 303 million, up 19% Year-on-Year. This bodes well for 2010 as a whole as shipments could reach 1.3 billion. It is also notable that 3G handset shipments eclipsed 2G handset shipments. The strongest handset shipment growth was seen in the Middle East and Africa (20% YoY) followed by the Americas, particularly the US (11%). Europe, on the other hand, is languishing with single-digit growth.Nokia’s market-share stood at 34%. New smartphones such as the N8 are helping the manufacturer to shore up its handset portfolio, as its loss of traction in the smartphone sector hit sales hard. In response, revamped efforts with Symbian ^3 and ^4, are intended to help Nokia regain momentum. Samsung had a strong quarter, securing 21%, and has been cultivating deeper relationships with US and European carriers which helped the firm grow its shipments 40.2% YoY.
M/A-COM Merges with Mimix
I think this will strengthen both companies as Mimix brings some very good pt. to pt. radio and other MMIC products into the M/A-COM family that complement M/A-COM's existing portfolio. After Tyco Electronics divided M/A-COM up and sold them off several years ago, this gives the remaining entity that will carry on the name and heritage some more size and broadens the portfolio as the regain their market presence.
The original M/A-COM now resides in 5 different companies:
- M/A-COM Technology Solutions has the commercial product lines
- Cobham has the aerospace/defense product lines
- Harris has the wireless systems (LMR) product lines
- Autoliv (Sweden) has the automotive radar product lines
- Micronetics has the RFID product lines
I believe M/A-COM Technology Solutions will be the company that carries on the name and the others will transition away from the brand. It looks like the company will leverage a hybrid fab model as they continue to operate the M/A-COM wafer fabs but also use external foundries for chip production. Mimix is a fabless company and M/A-COM was already transitioning to the hybird model to improve flexibility and reduce capital investments from what I could tell.
For a short history of M/A-COM, read our April special report "M/A-COM is Reborn on Its 60th Birthday". What do you think of the merger and implications on the industry?

Stranded Microwaver in Europe

[from Brian's e-mail]
David,
I don’t know much about blogging but I always have stories to tell.
One week in Europe including Sweden, Rome and Italy. After a few days in Stockholm at the S.E.E. (Scandinavian electronics event) my flight arrived in Rome on Thursday last week. Upon landing I checked my blackberry and saw several messages – from my mom, girlfriend and boss – concerning the volcano eruption which I had not heard about yet. I may have been one of the last flights out of Sweden since this was big news by the time I landed. Somewhere between baggage claim and customs I found the VP of Amplifier Design of Integra who had just arrived from Los Angeles and we made our way to Rome. We had meetings on Friday and were not planning on leaving until Sunday so the volcano seemed like a temporary disruption that would clear up soon surely by the weekend.
On Friday we visited Selex Systemi Integrati a big customer for high power RF transistors globally. The cancellations started expanding across Europe but we weren’t leaving until Sunday and that seemed far away. Saturday was site-seeing (St. Peters/Vatican City/Pantheon/Trevi Fountain) in Rome with plans to leave the next day if the skies opened up. Sunday morning the news seemed hopeful as the no-fly zones were intended to be removed that night. However it soon became apparent that the European agencies were being extremely cautious and the delays kept coming. The stress of the situation mounted quickly – another hotel night accommodation – same hotel, same room, a little over double the price! New tickets purchased through US travel agency that showed flights leaving EARLY Monday morning i.e. 6:30AM. This meant ordering taxi for 3:30AM and 2:30AM wake up calls.
A quick check of the Internet near midnight brought bad news – additional delays over all of Europe. Although we booked on a US domestic carry the flight was routed through Amsterdam. KLM of the Netherlands wished to start flying on Monday but the government would not allow it. This meant cancelled flight and cancelled taxi, however, my Italian must not be so good since the wake-up call still came! The problem is that the airspace has not been cancelled for a few days…no what they are doing is saying everything will open in 12 hours and that has been repeated for the last five days. So every time you check it seems ok but as the 12 hours get closer it moves another 12 hours. It reminds me of the bar back in NY with a sign saying “Special: Free Beer Tomorrow” and when you return the next day of course the same sign in place.
For clothing first you use your casual dress which soon runs out, then back to your business clothes which eventually run out, so today I am wearing a soccer jersey with the name of the local team captain on the back. With decent Internet connections work can still be done as hot ash does not stop emails from piling up. All and all I don’t expect much sympathy from friends, family and colleagues with being stranded in Rome for a week: history at every turn, great fashion, food and wine. Wednesday is Italy’s National Birthday and all museums were free. Thursday is my birthday and Friday we have flights back to US via Chicago via Chicago. Maybe.
Good luck Brian, we hope you make it home in time for your birthday.
Engineer leaves his work behind in a bar
Last month in Silicon Valley a very important cell phone was left behind at a bar -- what is widely believed to be a prototype of the new iPhone that Apple's officially going to release in a couple of months. The phone wound up in the hands of Jason Chen, the editor of the technology website Gizmodo.com.
In the news report, this phone was described at one point as Apple’s new 4G phone. Which initially grabbed my attention since I immediately thought they were talking LTE (whoa, that’s news), but I have since come to realize, that they were talking 4th generation iphone operating system. Oh well, it was still worth visiting the Gizmodo site and getting the skinny on the whole story and what the web site reporter’s investigation of the phone revealed before they returned it to Apple.
http://gizmodo.com/5520164/this-is-apples-next-iphone
Turning back to RF/microwave related concerns, I reviewed the gizmodo story with an eye out for relevant information. Here are some snippets about the new iPhone that relate to its radio. Among the most visible changes, is one of functionality over looks. The back is entirely flat, made of either glass (more likely) or ceramic or shiny plastic. Why the plastic back?
"The plastic back is the most obvious of the design choices. The iPad, with its all aluminum back, has seen its Wi-Fi reception radius reduced. The iPhone 3G version comes with a large patch on the top, probably big enough to provide with good reception. But the new tiny iPhone doesn't have the luxury of space: It needs to provide as much signal as possible using a very small surface. Industrial designers and fashionistas might be dying to get rid of the plastic back, and go iPad-style all the way, but the wireless reception is the most important thing in a cellphone. A necessary aesthetical-functional trade-off."
The “editors” then took apart the phone. Once open, they noticed that the battery takes up around 50% of the phone, give or take. Diving deeper became much trickier. There are a total of around 40-50 screws inside the phone, positioned at various angles that were almost frustratingly impossible to get to. The main logic board is one very weird piece of this puzzle. Unlike the iPhone 3GS teardown, which revealed a large logic board along with another part down by the dock connector, this design only has something maybe 1/3 of the size, along with one or two extraneous parts. Basically, the guts have shrunk drastically. The board was encased in metal all around so nothing could get through. EMI or IP protection?

Unfortunately, the editors failed to report on the front-end technology, changes to the antennas, power amps, switch modules and other RF components, etc. Oh, well, that’s information for a different audience than they were writing for, I suppose. We need a microwave editor for that. I'll have to ask my publisher for the new iPhone when it's available legally. The chances of me getting one are about as great as me being able to rip it apart.
Perhaps the bigger lesson is not to leave your work behind at the bar.

AT&T Leans on Femto-cells to Support iPhone Coverage
The Times reported the story of Christina Zachariades, 28, a Manhattan resident who already pays $130 a month for iPhone service but cannot receive or make calls in her fifth-floor apartment on the Upper East Side. Despite the additional cost to consumers, the technology is poised for big sales, thanks to price drops but also because of the entrance into the market by AT&T. Other companies — Verizon, for example — have already marketed their mini-towers for niche use to customers in places with limited cellphone signals, like basements or homes with particularly thick walls.
The article went on to describe how industry analysts stated that "mini-towers, known as femtocells, are poised for spectacular growth. Shipments should grow from 571,000 this year, to 1.9 million next year, to 40 million by 2013, according to iSuppli, a market research firm. Falling prices are helping propel sales. Two years ago, for example, consumers would have paid $500 or more. "
Cisco, Samsung and Netgear are among the companies that make the towers; Qualcomm and Texas Instruments, which make chips for phones, have also developed products. Francis Sideco, an analyst at iSuppli, said there were still bugs to be worked out before femtocells become a mass-market product like wireless routers or storage devices, which were once hard to market.
Over the long term, basic economics favors mini-towers in homes over big towers, said Pasquale Romano, chief executive of 2Wire Inc., a company in San Jose, Calif., that is developing one of the devices. Ramano claimed that it didn't make sense for carriers to spend money building large towers in residential areas because most people are not home during the day; as it is, AT&T already plans to spend $8 billion this year on improving its wireless coverage, including on big towers, according to public filings.
The price for the AT&T device could fall to $49 if consumers buy a broadband or in-home calling plan, and could be free to customers who buy both. Still, marketing mini-towers has its risks for AT&T. Even though it expects the towers to improve signal quality and take pressure off its network, they could displace landline telephones because wireless consumers will not need a second phone number.
At Microwave Journal, we’ve been following the Pico- and Femto-cell markets for a number of years now with news, articles and application notes from a variety of sources. Earlier this month we reported on the completion of the Femto Forum’s first Femtocell plugfest (Femto Forum Completes First Femtocell Plugfest ). GaAs power amplifier supplier, Anadigics has been targeting this market since 2008 (ANADIGICS Enters Femtocell Market ) and provided us with a white paper that same year
Last May we reported that femtocells, which were virtually non-existent in 2006, and deployed by one operator in 2007, would make up 61 percent of small cellular base station revenue by 2013, according to reports In-Stat.
Highlight's from last year’s In-Stat report included:
- Femtocells, picocells and microcells are expected to surpass 15 million units by 2013.
- Worldwide annual femtocell semiconductor revenue will approach $400 M by 2013.
- Sprint was the first to market with a femtocell-based service in 2007, while others entered the market in 2008.
- In mid-2009, Airwalk introduced a new enterprise femtocell. These products have the capacity of a traditional picocell and the ease-of-use of a femtocell.

Satellite LTE Network Planned by PE Firm
The network could help ensure competition among the major wireless carriers because of the conditions the FCC has placed on the spectrum that the private equity firm plans to use as part an agreement to let Harbinger take control of SkyTerra. SkyTerra would be a wholesaler, and that traffic from the wireless carriers in the U.S. cannot comprise more than 25 percent of the traffic over the SkyTerra/Harbinger network. This means AT&T and Verizon could not buy up huge chunks of the network or spectrum to keep others off of it.
The planned network would launch before the end of 2011 and cover 9 million people (trials initially planned for Denver and Phoenix). Then cover 100 million people by the end of 2012, 145 million by the end of 2013 and at least 260 million people in the United States by the end of 2015. Harbinger said in its statements to the FCC that all major markets will be installed by the end of the second quarter of 2013.
However, the 36,000 base stations that Harbinger plans to use, along with the tower sites, backhaul, etc. with a terrestrial network will require billions of dollars. Verizon and Clearwire have already started building out their networks and are investing billions. It is hard to see how Harbinher could afford to do this. According to SkyTerra, the network will have no less than 23 MHz of spectrum, consisting of 8 MHz of 1.4 GHz terrestrial spectrum, access to 5 MHz of 1.6 GHz terrestrial spectrum and 10 MHz of MSS/ATC L-band spectrum. Through a cooperation agreement with Inmarsat and associated waivers of the Commission’s ATC rules, by 2013 Harbinger will have access to an additional 30 MHz of ATC spectrum.
It will be interesting to see how this turns out.
Wireless Wee Wee
The main component is a remotely monitored disposable continence aid – the SIMpad®. It is fitted with a sensor strip (SIM™strip) that is completely safe for the wearer. A reusable SIM™box fitted to the front of the SIMpad transmits sensor readings wirelessly to a central monitoring station (SIM™server). A key component of the system is the SIMsystem™ Manager, software running on the SIMserver that incorporates an algorithm to analyse the sensor readings and provide an assessment of the continence event in real time; alerting the carer if required.
The SIMbox and SIMnetwork have been built for ZigBee® for low-power and low-range wireless applications. The SIMbox can operate continuously for at least 100 hours before the batteries need charging. The SIMnetwork platform consists of SIMboxes, SIMchargers, SIM repeaters which can extend the network, and a SIMgateway for connection to the central SIMserver. The SIMboxes are specially designed to be of minimal size and maximum battery life, to be flexible and compatible with a range of clinical applications.The SIMnetwork meets the essential requirements of the Australian1 & European2 standards and therefore is deemed EMC compliant so it is approved for use in healthcare facilities.

Updates and a Brief History of Aeroflex's PXI 3030
Applications include automated measurement of parametric performance of terminal transmitter and receiver characteristics, terminal TX and RX alignment and performance characterization for manufacturing, and research and development.
PXI OverviewPXI derives its name from the PCI eXtensions for Instrumentation specificationthat defines a rugged personal computer-based bus as the basis for a commonplatform for measurement and automation systems. PXI uses the high-speedPeripheral Component Interconnect (PCI) bus combined with the rugged, modular Eurocard mechanical packaging of CompactPCI and adds mechanical, electrical and software features that define complete systems for test and measurement, data acquisition and manufacturing applications. These extensions make it easy for end users and integrators to quickly build open, multi-vendor measurement and automation systems. The PXI was designed to bridge the gap between desktop PC systems and high-end VXI and GPIB bus systems.
In order to exploit the benefits of PXI, RF test system developers required first to have their needs met for performance and functionality, particularly in the areas of RF signal stimulus and RF signal analysis. The RF synthesizer has been used by Aeroflex since its inception as the underlying module for using PXI for RF instrumentation based upon the patented Fractional-N synthesizer. The 3020 Series RF signal generator modules are used in conjunction with the 3010 RF synthesizer to provide modulation and waveform generation, RF leveling and frequency tuning from 100 kHz to 6 GHz.The platform provides high yield and throughput, achieving dramatic improvements in test time using speed-optimizing techniques such as multi-thread processing, pipelined capture, and fast-sequence tuning (FST).

Capacity Constraints and LTE - Hot Topics at CTIA 2010
The keynote session kicked off the CTIA 2010 show with Ralph de la Vega, president and CEO AT&T Mobility and Consumer Markets, presenting the case that the US is the world leader in mobile broadband no matter how you measure it. The US has the most 3G subscribers (117 million), most WiFi hotspots (70,000), spends the most of wireless capital expenditures on mobile broadband (80%), the highest investment in LTE (30% in 2009), the most smart phones (53 million according to Strategy Analytics) and estimated 412 million M2M devices deployed by 2014. But he emphasized that the US must continue to innovate or this lead could evaporate quickly.He stressed that we are at a threshold now, so we must address the looming capacity issues as this expansion continues. The US is freeing up quite a bit more of spectrum to use for mobile broadband but we must also find more efficient ways to use the spectrum. LTE could be as much as 2.5 times more efficient than HSPA and the industry needs to work together to develop efficient apps. We also need to use other methods to supplement capacity such as WiFi and femtocells.
Steve Largent, president and CEO of CTIA, went on to say this is the 25th year of CTIA and showed the new "Freedom is Wireless" commercial being released. He stated that connected devices grew from 270 to 285 million from last year to this year and MMS grew 130% in 2009.
A video from the FCC chairman addressed the US Broadband plan spurring business and addressed the plan to free up spectrum. Then other CEOs went on to address their markets and businesses.The exhibition floor was very busy most of the day and many new phone announcements were made along with various apps. Yahoo was demonstrating their app where you could just draw a line or circle on Google maps and it would automatically list the restaurants within the immediate area.
The RF/Microwave Zone was busy with exhibitors from Freescale, JFW, Spinner, Times, Atrium, RF Electro Rent, Innertron, Trilithic, Park Electrochemical, RF Window, ACC, Rojone and Microwave Journal.
A full show wrap up will be coming in a few days covering the RF and Microwave companies and products.

Satellite 2010 - Brighter Days Ahead
The opening session on Tues with the CEOs from the big four (Romain Bausch, SES; Daniel Goldberg, Telsat; David McGlade, Intelsat; and Michel de Rosen, Eutelsat) showed that the companies are more optimistic about the market than they were last year. The needs to expand bandwidth and provide communication services to less populated areas are opportunities for satellite providers. The desire for countries to provide Internet access to more of those without access today is another area where satellite can be a solution. While satellite does not have data rates as high as fiber, it can provide coverage much easier to remote areas. But some want to push higher data rates (like 100 Mb/s) over more access. It was said, "Should we get 100% access at 10 Mb/s for everyone or get 100 Mb/s access but not 100% coverage." The cost to do both is probably too high so it would make sense to give everyone access first but people love to talk about very high speed access.There is concern about interference issues so coordination is a key issue to tackle especially with new bands and applications involving LTE, WiMAX, etc. Also concerning is that many view satellite solutions as too expensive and low in data rates when it should be an economic trade off depending on the service needs, coverage area, etc. It would not be fair to subsidize other technologies which could threaten higher data rate Ka-band implementations for satellite. But a combination of bands is the best solution depending on the needs of the service and area to be covered. Higher order modulation schemes, higher frequencies, etc. will eventually enable even higher data rates that satellite could deliver 100 Mb/s service for some needs.

The hot topics are comms on the move, security, lower power consumption (green tech), M2M/SCADA, video standards, hosted payloads, among others. There are forums on various subjects including the MSUA Conference co-located. They moved the event to the Gaylord outside of DC and found it was not large enough to accommodate all the exhibitors this year so it probably will move back to the convention center next year. That is good news for the industry.
I will have a full wrap up article covering all the RF/microwave companies we visited in the exhibition including the new products they were featuring at the show.

Hybrid Car EM Radiation Concerns
I find it hard to believe that the current levels in hybrids would be high enough to cause harm to someone in the car from EM radiation but it does not seem like anyone knows for sure. It has been suspected that EM radiation from power lines can be harmful if you live close to them but I don't think that has been proven either. It is also like cell phone radiation exposure - there is no conclusive data that it is harmful. If the current level in hybrids is dangerous, then the higher currents produced in pure plug-in electric cars would be even worse as there motors are larger than those in hydrid models. It also should be possible to shield the wires if there are concerns about their safety.
Has anyone seen data on actual measured EM field values and how it compares to the allowed standards? I have also seen reports that such EM fields can be beneficial to our health so who knows how they truly affect our bodies overall. Please chime in with your opinions as this might be a topic we cover in a future article.

ADI Poised for Growth – RF and Converters Emphasized
I was surprised to learn that the Barry Gilbert who invented the Gilbert Cell mixer works at ADI and still leads their development efforts in that area. The also emphasized their expertise in fast hoping PLL synthesizers and RMS detectors along with variable gain amplifiers. They recently released (ADRF670x and ADRF660x) a transmit modulator and receiver down converter that integrate many functions onto a single chip for high performance infrastructure applications. They expect strong RF growth in the medical, wireless infrastructure and building automation (smart grids, security, etc.) markets and they expect to grow at over 15% in the RF market going forward. It is good to see companies expecting large growth this year in the RF market.

First Junctionless Transistor Fabricated
A team of scientists at the Tyndall National Institute have designed and fabricated the world's first junctionless transistor that could revolutionize IC chip manufacturing. Existing ICs are based on junctions which turn the current off and on to control the device but in the junctionless Tyndall device, the current flows in a very thin silicon wire and the flow of current is controlled by a ring structure that electrically squeezes the silicon wire to control the current. These devices are easier to fabricate and can be made on a smaller scale than current junction devices which seem to be nearing their limit for miniaturization. The junctionless devices also act more like a perfect transistor so they have less leakage current and could reduce power consumption.I wonder how a RF junctionless transistor would behave. Any insights or thoughts?

Potential GPS Security and Reliability Risks
They reported that experts met in the UK at the National Physical Laboratory in Teddington on Feb 23 and professor David Last, a past president of the Royal Institute of Navigation and now a GPS consultant stated, “A portable jammer in a tall building could cover most of London and aircraft approaching its airports. GPS gives us transportation, distribution industry, 'just-in-time' manufacturing, emergency services operations - even mining, road building and farming, all these and a zillion more. But what few people outside this community recognize is the high-precision timing that GPS provides to keep our telephone networks, the internet, banking transactions and even our power grid online.”
They said that jamming devices that can disrupt GPS signals are sold on the Internet for around $100. Last was also quoted as saying “GPS now is like computers before viruses. But there are no big security companies working to protect GPS.” He explained that the gadget could be used to "spoof" a location -- useful to evade GPS based tolls or worse to set others off course. "You can now buy a low-cost simulator and link it to Google Earth, put on a route and it will simulate that route to the timing that you specify," said professor Last.
I am sure the military portion is a better protected but how about personal navigation and public safety applications. Even if jamming is defeated, spoofing would be difficult to stop since it would be localized to a specific area.
There were also previous reports that the US GPS system was aging and nearly its design life for many of the satellites. It was stated that satellites would reach their end of life much faster than they could be replaced weakening the network to the point where accuracy and coverage could be decreased. The reliability and security issues of the US system are concerning. How dangerous do you think it really is? Any insights from technical people involved in such systems??

Short Range Wireless Taking Off
Bluetooth took more than 55%, following by WiFi at around 35%; the rest of the shipments were made up of NFC, UWB and 802.15.4 ICs. Mobile handsets maintain the highest adoption rate for Bluetooth ICs. In addition to data transmission between mobile handset and Bluetooth headset, the application of Bluetooth technology is gradually moving into computers and consumer electronics products such as laptops, UMDs, and the wireless remote pole of game consoles.
Low power consumption and short range transmission are two key technical features of Bluetooth technology. Furthermore, in December 2009 the Bluetooth Special Interest Group (SIG) announced the adoption of Bluetooth low energy (BLE) which opens an absolutely new market for products and devices needing low cost and low power wireless connectivity. Likely vertical markets include healthcare, security, and home entertainment. Chip manufacturing technology migration is driving down chip cost too, and as Bluetooth chip ASPs continue to decline, new business opportunities will be created.
Combination chips, integrating two or more short range wireless technologies to deliver further cost reduction and chip size decreases, are paving the way for another trend in short range wireless IC market development. The three major integration solutions — Bluetooth+FM radio, Bluetooth+WiFi+FM, and Bluetooth+FM+GPS — are forecast to account for more than 30% of all Bluetooth combination chip shipments in 2010. The combination chip using BLE is expected to make up 50% of total Bluetooth combo IC shipments in 2014.
TriQuint has plans to release a combination WiFi + Bluetooth front end module soon and others are probably working on similar architectures for future products. These are becoming ubiquitous functions in all of our electronics from cameras and mp3 players to printers and phones. The best option on my car is the handsfree Bluetooth option for my radio.

Mobile Commerce Gets Attention at Mobile World Congress 2010
ABI Research projects that in 2015, shoppers around the world are expected to spend about $119 billion on goods and services purchased via mobile phones. That number represents about 8% of the total e-commerce market. “Mobile online shopping is reaching critical mass,” says senior analyst Mark Beccue. “In the United States, mobile online shopping rose from $396 million in 2008 to $1.2 billion in 2009. While definitions of ‘mass market adoption’ vary, a more than threefold increase in one year indicates significant consumer interest." Noteworthy is that even that $1+ billion turnover in the US is dwarfed by the size of the mobile online shopping market in Japan, which exceeded $10 billion in 2009 alone. This market is growing solidly in Europe too, and is expected to outpace the US by the end of 2010.
In another ABI report, they project that in 2015 about 407 million people worldwide will carry out financial transactions with their banks using their mobile phones. Of those, some 66 million will be in North America. Beccue commented, “It’s not the North American market that is moving fastest to mobile banking: that crown goes to the Asia-Pacific region, which accounted for the lion’s share of the world’s 52.2 million mobile banking subscribers in 2009. The global number of subscribers more than doubled between 2008 and 2009, and is expected to almost double again in 2010. This growth can be seen everywhere, but Asia – led by India – is pushing it particularly hard.”
Do you feel comfortable using your phone to purchase goods? Microwave Journal editors David Vye and Richard Mumford were on site and will report their findings next week.

Forecast for Smartphone Market and Chips
Some of the key findings are:
· Smartphone shipments worldwide grew 18% in 2009 to 171 million units at a $67 billion level, providing bright market opportunities for both handset and chip vendors in the current economy. The Smartphone semiconductor and display revenue also covered in the report reached $11.7 billion.
· With the economy expected to continue improving, they forecast a compound annual growth rate of 24% for Smartphones to the 496 million unit level in 2014.
· Nokia continues to be the leader in Smartphone shipments, with an estimated 2009 market share of 36.4%, followed by RIM at 19.4%, Apple at 14.9% and HTC at 6.3%. Sharp follows with a 3.5% market share, then Samsung at 3.4%. 18 other Smartphone vendors constitute the remaining 20% share.
· Western Europe has overtaken Japan to be the leader in Smartphone consumption, with a 23% 2009 market share. However, thanks to the iPhone and the introduction of Android phones, North America is forecast to become the leading Smartphone market in 2010, with a forecasted 22% share, closely followed by Western Europe at 21.6%, and fast-growing China at 17%.
· Symbian continues to be the leading Smartphone operating system, with an estimated 43% unit market share in 2009, while RIM's Blackberry O/S and Apple's O/S X has supplanted Microsoft Windows Mobile for the #2 and #3 positions; RIM with an estimated 19% share and O/S X with 15%. Windows Mobile had a 13% share while Linux variants, including Android, reached 8%, followed by, Palm’s WebOS with 2%. Although Symbian is expected to remain dominant, we predict that Android will grow to the #2 position, followed by O/S X in 2014.
On author said that 2009 was the year of Smartphone applications, with Apple’s leading App Store having reached 140,000 applications. All major O/S vendors have followed suit, especially Nokia with its own Ovi initiative. Mobile Internet uptake also remained strong during the year, posting a 29% YoY growth, reaching 500 million subscribers.
This forecast is a good follow on to the previous post on ABI's handset shipments report for last quarter. You would never know if in the US but Nokia and their platform still dominate the world of handsets. It will be interesting to see how fast Andriod based smartphones are adopted by the market and how that affects the iPhone market share.

ABI Reports Handsets Shipments Up in Q4
The US stimulus package certainly helped save the mobile handset industry according to Saunders. “Renewed consumer confidence in the second half of 2009 meant that shipments for the whole year only shrank 4.5% to 1.153 billion. Dire scenarios were mooted in early 2009. There is cautious optimism about 2010 despite the fragile nature of the global recovery. ABI Research forecasts shipments to expand to 1.2 billion handsets in 2010.”

Despite Nokia’s weakened position in the smartphone segment, it still managed to maintain 37.7% of the overall handset market. Samsung seems unstoppable - between June 2008 and December 2009, they increased its market share from 15.2% to 20.5%. Samsung has benefited from a strong line-up of feature phones as well as a strong reputation for innovative smartphones. Korea’s level of influence over the handset market is further underscored by LG, the third-largest handset vendor (10.1%). LG has been counting on its S-Class smartphone series to help it secure a bridgehead in the market.
“In 3Q-2009, Motorola, under the direction of Sanjay Jha, has come out of its corner fighting with a refreshed portfolio,” adds practice director Kevin Burden. “The Droid has received critical acclaim. However Motorola’s market-share continued to contract to 3.6%.” Sony-Ericsson also experienced a contraction to 4.3% but has high hopes that its Android-based handsets will generate renewed interest. It only seems like a few years ago that Motorola was approaching Nokia for the market leading position but they have really suffered over the years.
HTC’s market share did not fare well early last year. but its circumstances improved slightly in 4Q, to 1.0% share. Notably, HTC announced a revamped handset portfolio strategy, not just targeting high-end smartphones but also launching smartphones that appeal to purchasers with smaller wallets. These low cost “HTC Smart” devices will rely on BREW.

“Smart” Electric Meter Market to Exceed $200B by 2014
Practice director Sam Lucero says, “As momentum for infrastructure renewal grows, a number of factors are driving the process. High on the list are government regulators. In the US, $3.4 billion in federal economic stimulus funding was directed to smart grid development in November 2009. The Energy Independence and Security Act of 2007 (EISA 2007) directly encourages smart grid technology adoption by the states, and funds NIST’s efforts to develop a standards-based technology framework to facilitate smart grid adoption.”
For its part, the EU recently enacted a “Third Energy Package” in September 2009 which aims to see every European electricity meter “smart” by 2022.
There are also tantalizing hints of a massive upgrade in China. “Although nothing is confirmed,” notes Lucero, “it has been suggested that China will replace 300 million electricity meters over the next five or so years.”
Other drivers include:
· Efficiency and reliability gains
· Environmental concerns
· Improved customer service
· Energy theft reduction
· Increasing energy market competition
However the path to smart metering is not always smooth. PG&E in California has been one of the early utilities to deploy smart meters, but the rollout has led to claims by consumers that they have been overcharged. PG&E stands by the accuracy of its meters, but the controversy has created a public relations headache – which Lucero terms a “temporary hiccup” – for the firm.
Several microwave companies are designing devices and solutions specifically for this market such as Skyworks, Analog Devices, etc. We will be covering this market as its emerges into the mainstream.

Driving around in my Infotainment-mobile
Much of the responsibility for the quality of the infotainment system rests with the designers of in-car radio. Thanks to technological breakthroughs in integrated circuits, filters, amplifiers, and antenna designs, sound quality has improved with each new generation of receiver. Broadcasting technology itself has also been upgraded through the Radio Data System (RDS) extension, which offers specialized features for mobile receivers.
Terrestrial digital broadcasting systems, such as digital audio broadcasting (DAB), HD-Radio, Digital Radio Mondiale (DRM), and satellite radio, offer a suite of attractive advantages, although they are still striving to achieve mainstream customer awareness and high-volume market success.
Since more radio functions generally requires additional hardware, available space within the automotive radio-head unit is hard to come by. The compact nature of the electronics also leads to power consumption and heat dissipation problems which must be addressed. The close proximity of electronic systems within the radio-head unit can cause interference and electromagnetic compatibility (EMC) issues, which can result in serious performance problems. This is especially true for sensitive analog building blocks such as the receiver front end and signal lines. Designers must work carefully, using shielding and rigorous testing, to verify that the effects of EMC and interference can be controlled.
Developing next-generation automotive radio platforms that are cost-effective and robust enough to meet customer demands will be a challenge for both OEMs and suppliers. The rapidly accelerating technologies of these systems will require robust product design followed by thorough product qualification. These challenges along with the growing market demand spell potential job opportunities for system designers and engineers with a good handle on EMI issues. We just need to keep our eyes on the road.

Shape Shifting Liquid Antennas
I am a little late in catching this story from Dec, but it is too interesting to pass up. Researchers at NC State published a potentially revolutionary technology for antenna design, liquid antennas. The antenna consists of liquid metal injected into elastomeric microchannels. The antennas can be deformed (twisted and bent) since the mechanical properties are dictated by the elastomer and not the metal. Creating shape-shifting antennas could open the door to a host of new uses in fields ranging from public safety to military applications.The new antennas are made by injecting a eutectic alloy of Ga and In, which remains in liquid form at room temperature, into very small channels the width of a human hair. The channels are hollow with openings at either end but can be any shape. Once the alloy has filled the channel, the surface of the alloy oxidizes, creating a “skin” that holds the alloy in place while allowing it to retain its liquid properties.
