IMS2011 First Impressions
The Baltimore inner harbor area is a beautiful setting for the IMS2011 and certainly convenient for us on the east coast. The sessions are in full swing with some very interesting topics being presented. I see trends in very high efficiency amplifiers with better modeling/measurement techniques, new packaging techniques from LCP to fusion bonded laminates, very wideband active devices to cover multiple frequency bands, highly integrated modules that solve co-existence problems, new signal generators that provide real life signal replication and storage and more.
Yesterday we attended the Women in Microwaves reception at the Hilton which is growing each year and then made our way down to the inner harbor for the MWJ customer appreciation party at the Tir Na Nog. It has a nice deck overlooking the harbor with great beers and a nice buffet. I hope everyone who attended had a good time.Friday, June 3, 2011
Heading Off to IMS2011 in Baltimore
The biggest surprise leading up the show for me was all the acquisitions (Skyworks acquired SiGe and Advanced Analogic Tech plus NI acquired AWR and Phase Matrix). In addition, the abundance of news items and new product releases has already been at the highest level that I can remember which should make for an interesting show.
Microwave Journal will host the MicroApps Nonlinear Characterization Forum on Wed at noon which will be webcast live from the event. After the experts from Agilent, Anritsu, R&S (NMDG) and Tektronix (Cardiff Univ) speak, there will be a Q&A session with both the live and virtual audiences, a first for IMS.
The Plenary Session will be given by Dr. Rhodes, "Migration of WCDMA and 4G LTE Into Existing Cellular Bands". Our May Cover Story was about the history of filter companies in the Maryland area and mentions Dr. Rhodes' accomplishments in this area. The closing keynote session is given by Dr. Guerci who is an expert on Cognitive Radar and was the author of our Cover Story in Jan this year.
It should be an exciting show this year and it is a nice short flight for us from the Boston area. Let us know how you are making out at the show and if you have any exciting news.

New TASC Report Defines Cyber Vulnerabilities
“The integration of the Internet into critical operational structures of all levels of the government, the military and the nation’s economy has created a collective reliance on information technology that will only increase in the coming years,” says Steve Winterfeld, cyber technical lead at TASC. “Today the growing dangers of cyber warfare present a new national threat—one that demands a national commitment.”
The report, “Understanding Today’s Cyber Challenges,” groups the nation’s primary cyber threats into three categories: psychologically driven cyber challenges, process-driven challenges and technologically driven cyber challenges. These challenges range in severity from those that can be quickly and easily addressed to those that require sustained, long-term investment.
“Daily security breaches threaten everyone who operates in cyberspace,” says Winterfeld. “We face more devastating attacks as cyber thieves, nation-states and others become increasingly sophisticated in their knowledge of today’s networks.”
Government agencies and businesses can use the TASC report as a tool to categorize risks and mitigation practices most relevant and appropriate to their organizations. The study was produced in collaboration with the University of Virginia.
“Before 9/11, no one imagined an attack of such magnitude could happen anywhere, especially on U.S. soil,” says Winterfeld. “The threat of a cyber calamity of similar proportions is real, and such an attack would have far-reaching impacts at every level of our society. We urgently need to reach a common understanding of what those threats are and do what we can to mitigate them.”

Advice for IMS2011?
Unmanned US Military Expenditures to Total $64 billion by 2021
While the global economic crisis has led to a reexamination of defense budgets, there remains concern for improved battle space integration, leading to support for the development of UCAV (Unmanned Combat Aerial Vehicles) platforms. This, in turn, will drive growth in the demand for EO-IR (electro-optic/infrared), radar, communications and EW (electronic warfare) systems and other associated electronics.
“Strategy Analytics analysis indicates that the UAS segment will maintain a growth trajectory, accounting for 31 percent of US DoD budget expenditure on aircraft platforms by 2021,” noted Asif Anwar, Director, Advanced Defense Systems. “The US military market for UAS platforms will grow at a compound annual growth rate of 3 percent over 2011 – 2021.”
Eric Higham, ADS Service Director, North America, added, “EO-IR payloads for intelligence, surveillance and reconnaissance (ISR), as well as radar and communications, represented 75 percent of military electronics demand in 2010, which Strategy Analytics projects will grow to 80 percent by 2021. This will create a cumulative market opportunity approaching $21 billion.”
One example is the Boeing Phantom Ray UAS which successfully completed its first flight April 27 at NASA's

Comparing Active and Passive Mixers with Besser Associates

Post-webinar response from Allen Podell -
First of all, I must admit that it is true that the ADL5801 and the LT5557 mixers mentioned were quite comparable in performance to the combination of the passive mixer and IF amplifier given as an example. Let me point out that the power consumed by the amplifier in the example was about 10% of the example HDR mixers. My statement was that Gilbert Cell active mixers were inferior in dynamic range, based on their figure of merit. Even 10 of the Avago mixers would not have been as good as the course example, at a much high dc power consumption. Are the ADL and LT active HDR mixers truly Gilbert Cell mixers, as the Avago part is?
I tried to research the Analog Devices and Linear Technology recent patents to determine the design used in these mixers, but could not find an answer. Eliminating the common emitter amplifier stages and replacing them with a transformer would improve the performance of the active mixer, but it would no longer be a Gilbert Cell mixer. Had I used in my example a feedback IF amplifier running 80 mA and a Peregrine FET mixer together, we could have built an HDR mixer about 10 dB better than that of the example.
We could then re-start the mixer war.

JSF Makes First Public Fly Over Appearance
The F-35C is a 5th generation strike fighter with stealth capability and has larger wing surfaces and reinforced landing gear for the demanding carrier environment for the Navy. The Lockheed Martin F-35 Lightning II Joint Strike Fighter program is in the system development and demonstration phase, focusing on delivering three different and new aircraft variants to the US Marine Corps, Navy and Air Force and NATO.
This is an important program for RF/microwave companies as many of them are involved in the radar and EW systems development and production. It is one of the few programs that has some potential for a large number of units as the F-22 production quantities have been cut many times of recent years.

Anritsu Techtime Tour Visits Boston Area
I attended the Anritsu Techtime Tour this week (co-sponsored by AWR) since it was in our neighborhood in Chelmsford, MA. The Techtime Tour is a complimentary full-day educational seminar focused on the applications of Vector Network Analyzers (VNAs). Presentations included both lecture and live demonstrations presented by industry experts and allowed everyone to ask questions.The topics covered were:
- VNA Fundamentals
- Advanced Amplifier Design and Test Including Nonlinear Measurements
- Advanced Time Domain Techniques
- Co-Simulation with Real-Time Channel Measurements
The session covered everything from the basics to the more advanced subjects in the afternoon so there was something for everyone. This was the last stop of the 6 city tour which included 2 stops in CA, 2 in TX, NJ and the Greater Boston. There are typically around 50 people who attend these sessions and if this tour is successful, they will try to continue having them from time to time.
I met one very interesting guy there who had his own personal VNA in his backpack. I was curious to see what he was using and he told me it was a VNWA which can be purchased as an assembled kit online for about 400 pounds from SDR-kits.net in the UK. It works up to about 1.3 GHz and he showed me the unit in action by measured a homemade filter he had rigged up. It is only 10.4 x 8 x 4.6 cm weighing 0.2 kg. A far cry from the VNAs sold by Anritsu but it is an interesting product.
Anritsu does have a big announcement for its VNA product line being released for IMS MTT-S so catch the news on the MWJ Online Show Daily.

MWJ Article Forecasts Technology used to Report Bin Laden Operation
our August Military Microwave supplement. While the Journal and its staff has no obvious connection to the administration, military and intelligence community behind this successful covert operation, we do have a connection to this story by way of an article we were about to publish that month. The previous fall at the Milcom show in Boston, I had read an article by Dr. Simon et. al. of Queen’s University in Belfast on millimeter-wave ad hoc personal communication system for war fighters. I had invited Dr. Cotton to author the cover story for our Military supplement and he along with William Scanlon (Queen's University of Belfast), Efstratios Skafidas (University of Melbourne) and Bhopinder Madahar (Ministry of Defence, UK) graciously accepted our offer. The article was entitled, “Millimeter-wave Stealth Radio for Special Operations Forces”.The Abstract read as follows:
For Special Operations Forces, an important attribute of any future radio will be the ability to conceal transmissions from the enemy while transmitting large amounts of data for situational awareness and communications. These requirements will mean that military wireless systems designers will need to consider operating frequencies in the mm-wave bands. The high data rates that are achievable at these frequencies and the propagation characteristics at this wavelength will provide many benefits for the implementation of ëstealth radioí. This article discusses some of the recent advances in RF front-end technology, alongside physical layer transmission schemes that could be employed for millimeter-wave soldier-mounted radio. The operation of a hypothetical millimeter-wave soldier-to-soldier communications system that makes use of smart antenna technology is also described.
I thought of these high speed data communication networks when I heard that the White House and operation leaders were watching the action in Pakistan unfold in real-time. After years of developing microwaves for weapon systems created and used during the Cold War, perhaps older Microwave Journal readers are well accustomed to knowing the technology story behind the headlines, but it still gives me the chills when it happens. I invite everyone to go back and read Dr. Cotton’s article now that it has moved from science fiction to forecast to fact.

Stealth Technology is Being Applied Everywhere
We learned last week that Navy SEALs probably used advanced technology on the Sikorsky choppers used in the raid on Osama bin Laden's compound in Pakistan. Military aviation experts have been poring over photographs of the debris (photo courtesy of Reuters), particularly the tail section, of the Black Hawk that had a hard landing and was purposely destroyed to protect its technology.Exactly how the Black Hawk helicopters were modified is not completely known, but the photographs of the wreckage offer new clues to the military's cutting-edge methods. Several analysts agreed the aircraft used technology that appeared to stem from the Comanche, a $39 billion, joint project between Sikorsky and Boeing until it was scrapped in 2004 due to high costs. The tail rotor was modified with a dish covering part of the rotor to suppress noise and the tail section was modified to reduce it radar cross section. In addition, there was evidence of radar absorbing materials being used on the Black Hawks.
Also last week, Boeing announced that its Phantom Ray unmanned airborne system (UAS) successfully completed its first flight April 27 at NASA's Dryden Flight Research Center at Edwards Air Force Base, Calif. This is a stealth unmanned platform which is obvious from its shape. The 17-minute flight took place following a series of high-speed taxi tests in March that validated ground guidance, navigation and control and verified mission planning, pilot interface and operational procedures. Phantom Ray flew to 7,500 feet and reached a speed of 178 knots.
The flight demonstrated Phantom Ray's basic airworthiness, setting the stage for additional flights in the next few weeks. These company-funded flights will prepare Phantom Ray to support potential missions that may include intelligence, surveillance and reconnaissance; suppression of enemy air defenses; electronic attack; strike; and autonomous air refueling.
Stealth technology is being applied to most combat aircraft built in the US these days, so it is a pretty safe prediction that all future US combat aircraft will be built using stealth technology and might even be all unmanned going forward.

Can RF Benefit from 3D Transistor Technology?
If you have not already seen it, the Tri-Gate transistor is really a FinFET which was invented about 10 years ago. The gate metal wraps around the active channel on three sides of the fin like structure of Si allowing it to better control the current. It has less leakage in the off state and allows better current flow in the on state making the FET more efficient. Here is the nice video Intel released showing how it works.
FinFET transistors suffer from stronger device parasitics compared to planar bulk transistors and tend to have lower cutoff frequencies. However, the improved performance of FinFET transistors is motivation for more work in this area, especially for reducing power consumption. There have been some papers on RF FinFETs - many of them on dual gate structures instead of Tri-Gate but the results seem limited. Has anyone seen some more recent work with RF FinFETs/Tri-Gate devices?

Weather Radar Technology Captures Tornado Activity
One NASA platform that provided vital information is the Tropical Rainfall Measuring Mission (TRMM). The TRMM has several instruments including a Precipitation Radar that was the first space borne instrument designed to provide 3D maps of storm structure. These measurements yield information on the intensity and distribution of the rain, on the rain type, on the storm depth and on the height at which the snow melts into rain. It can provide vertical profiles up to 12 miles and detect fairly light rain rates down to about .027 inches per hour. The Precipitation Radar uses a frequency 3 times higher than similar ground based systems in order to obtain high resolution images. It uses 128 solid state power amplifiers to provide a robust design and minimize power consumption (it only uses 224 W). As the beam size is small, it also utilizes scanning phased array technology to steer the beam over the target area.
The TRMM also has a Microwave Imager (TMI) whichi is a passive microwave sensor designed to provide quantitative rainfall information over a wide swath under the TRMM satellite. By carefully measuring the minute amounts of microwave energy emitted by the Earth and its atmosphere, TMI is able to quantify the water vapor, the cloud water, and the rainfall intensity in the atmosphere. The TMI measures the intensity of radiation at five separate frequencies: 10.7, 19.4, 21.3, 37 and 85.5 GHz. Calculating rainfall rates from TMI requires fairly complicated calculations using Planck’s radiation law, which describes how much energy a body radiates given its temperature.
The primary instruments for measuring precipitation are the Precipitation Radar, the TMI, and the Visible and Infrared Scanner. Additionally, TRMM carries the Lightning Imaging Sensor and the Clouds and the Earth’s Radiant Energy System Instrument. These instruments can all function individually or in combination with one another. TRMM is part of NASA’s

The TRMM satellite saw severe weather over the eastern
Ground radar systems have added the capability to create very detailed 3D images of severe weather. One reason for this is the use of dual polarization radar. The images and descriptions below were taken from an article written by Jason Samenow in the Washington Post:

These newer tools should help scientists learn more about these storms and improve our warning systems. All these images and capabilities enabled by RF engineering!

M2M App Developers Projected to See Lower Module Prices
According to ABI Research, Mobile operators AT&T and Sprint have recently struck deals with cellular embedded module vendors to provide modules for M2M (machine-to-machine) application developer partners at discounted rates. Their goal is to encourage app developers to embrace 3G – and now 4G – M2M modules.
The M2M market largely consists of low data rate, low data consumption applications where 2G technology is perfectly adequate. Given a choice, M2M application developers would prefer to stay with older technology that is not only adequate from a connectivity standpoint, but more optimized from a cost component standpoint. In 2010, a 2G GSM/GPRS cellular embedded module cost approximately $18, while a 3G WCDMA module was roughly $65.
ABI Research forecasts that as WCDMA module shipments grow from less than four million last year to more than 62 million in 2016, ASPs will fall by more than half, approaching $30 in 2016. According to ABI Research practice director Sam Lucero, “The operator-module vendor deals we are seeing today may cause that ASP to be reached much sooner for the overall WCDMA market.”
The operators, in contrast, want all data devices on the network to use the most spectrally efficient technology – 3G or even 4G rather than 2G. “It makes sense for the mobile operators to do whatever they can to facilitate adoption of 3G/4G technology by the M2M ecosystem,” notes Lucero. “The AT&T/Sprint deals are examples of just such symbiosis: large mobile operators using their size to benefit typically much smaller M2M application developers.”
AT&T is working with Ericsson, Huawei and ZTE (the latter two being leading China-based module vendors) while Sprint has selected Fusion Wireless, an innovative new CDMA-focused module vendor based in
I still think companies deploying these systems will be very cost driven so it will be a hard sell for the operators to force companies to use newer technology where the module cost will always be higher. The incentives will have to be substantial for them to adopt 3G/4G technology.

FCC Decision Could Lead to Interference Among GPS Receivers
Coalition Warns Recent FCC Decision Could Harm U.S. Economy and Exports. Threat of GPS Interference Could Have Unintended Consequences
As the House Energy and Commerce Subcommittee on Communications and Technology begins its in-depth examination of spectrum issues, the Coalition to Save Our GPS submitted a detailed statement warning that a recent FCC decision that may disrupt the Global Positioning System(GPS) could have the unintended consequence of giving the Chinese, Russians, and Europeans competitive and economic advantage over the United States.
The “Coalition to Save Our GPS” is working to resolve a serious threat to the Global Positioning System. The threat stems from a recent decision by the FCC to grant a conditional waiver allowing the dramatic expansion of terrestrial use of the satellite spectrum immediately neighboring that of GPS, potentially causing interference to millions of GPS receivers. The FCC granted the conditional waiver for a proposal to build 40,000 ground stations to a company called LightSquared.
A portion of the Coalition’s statement follows:
“The Global Positioning System has stimulated a multi-billion dollar global industry that contributes both to the domestic economy and to U.S. exports. However, the Chinese, Russians, and Europeans are all developing their own GPS systems. If the rest of the world concludes that the U.S. system is compromised by interference, those other powers are ready to step forward to assume global leadership in this critical and highly sensitive area.
“LightSquared's proposal to build 40,000 terrestrial base stations operating at 1 billion times the power levels of GPS signals as received on Earth represents a tectonic change in the use of the L- Band. While the GPS community supports efforts to add new broadband competition and free up spectrum for mobile uses, this must be done in the context of rational, long term spectrum planning, rather than the rushed, ad hoc waiver process followed by the FCC to date. Spectrum is a public asset and it should not lightly be handed over at the behest of a private party. More fundamentally, the laws of physics cannot be waived by the FCC. The placement of LightSquared’s high-powered ground-based network in the middle of a satellite band full of weak and distant signals is a recipe for massive interference.”
Members of the Coalition include the Aeronautical Repair Station Association (ARSA), Air Transport Association (ATA), Aircraft Electronics Association (AEA), Aircraft Owners and Pilots Association (AOPA), American Association of State Highway and Transportation Officials (AASHTO), American Car Rental Association (ACRA),American Congress on Surveying and Mapping (ACSM), American Council of Engineering Companies/Council of Professional Surveyors (ACEC/COPS), American Rental Association (ARA),Associated Equipment Distributors (AED), Association of Equipment Manufacturers (AEM), Avidyne Corporation, Case New Holland, Caterpillar, Deere & Company, Edison Electric Institute (EEI), Equipped to Survive Foundation, Inc.

Assessing Japanese Quake Impact on GaAs Industry
Strategy Analytics issued a report today that the impact of the March 11 earthquake and ensuing tsunami, as well as the on-going issues with the nuclear reactors at Fukushima, are affecting the equipment and materials suppliers, consumer electronics companies, automotive, test and measurement companies in Japan. The Strategy Analytics' GaAs and Compound Semiconductor Technologies (GaAs) service report, “Japanese Quake Impact on the GaAs Industry,” contains a preliminary assessment of the impact of the tragedy on the global GaAs industry in Japan and throughout the world.
Strategy Analytics assessment of the situation indicates that there is no danger of immediate disruption to the supply of gallium and arsenide raw materials. The supply of SI (semi-insulating) bulk substrates will also be sustained. GaAs device manufacturing facilities were also largely unaffected. They state that the Japanese materials supplier were running at full capacity when the quake hit so if there was a surge in demand, shortages could result.
Japan is a leading player in the GaAs RF/microelectronics industry, accounting for 50 percent of bulk substrate supply, 18-20 percent of global SI GaAs epitaxial substrate production and up to one-fifth of the global GaAs device market. Japanese companies involved in the GaAs industry include Hitachi Cable, Renesas and Sumitomo Chemical.

TI to Acquire National Semiconductor
TI announced late yesterday that it is acquiring National Semiconductor. The purchase was for $25 per share in an all-cash transaction of about $6.5 billion and creates a combined product portfolio of 42,000 products.
Here is a letter Templeton wrote to stakeholders:
I am excited to let you know that TI has signed a definitive agreement to purchase National Semiconductor, uniting two industry leaders that have a common commitment to solving your analog needs. I want to reinforce TI's commitment to you, our customer, as we merge our two companies.
This acquisition will allow us to address your analog needs with a product portfolio of unmatched breadth and depth. National's 12,000 products plus TI's 30,000 means more performance, power and packaging options when selecting the right ICs for your application. And we'll provide a common set of best-in-class online tools to make the selection and design process easier.
Our combined sales and applications team of 2,500 will be larger than any in the industry so we can provide more customers with greater face-to-face support than ever before.
Our manufacturing operations will offer more capacity to support your growth. TI's fabs and National's available capacity can enable higher production levels.
While both companies will operate independently pending the close, our goal thereafter is to make the integration process as seamless as possible. No requalification of products will be necessary since National's manufacturing sites will continue to be utilized. Part numbers from both companies will remain the same. There will be no obsolescence of products.
I'm excited about what the integration of our two companies will mean for you: an unmatched portfolio to meet your analog needs, an extensive sales and applications network to ease the design process, and manufacturing capacity to support your growth.
You can learn more about the acquisition at www.ti.com/acquire, including answers to frequently asked questions and video messages from TI leaders regarding the acquisition.
Thank you for choosing TI. I look forward to a great future together.
Best regards,

Active Antenna Markets Projected to Exceed $2 B by 2016
ABI Research released a new report last week that looked interesting to me. They stated that the global market for antennas for wireless infrastructure, including base station, fixed and active types, is set to reach almost $2.0 billion in 2016. So-called “active” antennas are the hot segment of this market. Widespread installations of active antennas, which combine the base station’s RF electronics in the antenna housing mounted at the top of the tower, have only begun quite recently.
According to research director Lance Wilson, “Active antennas offer a solution to the problem of rapidly growing wireless data traffic. Conventional designs are not as efficient; active antennas offer much greater efficiency and versatility when handling large quantities of signals, including wireless data.” Apart from the “active” segment, the antenna market can be described as stable and mature. “Market growth is gradual and steady,” says Wilson. ”That, along with the huge size of the market (from a component or subassembly standpoint), is precisely part of its appeal for vendors.”
The antenna vendor ecosystem is slightly unusual in that there are multiple tiers and many participants. The bulk of these vendors are small companies that command only fractional percentages of the total available market (why is that?). ABI Research believes that some market consolidation is likely. The scenario for active antennas is a bit different, with antenna manufacturers normally partnering with equipment builders.
Will 4G provide much stimulus to the antenna market? “Some upside is present with LTE/4G,” says Wilson, “but this will be moderated by the eventual decline in the GSM family of technologies. With the exception of still-developing regions, GSM infrastructure is largely built-out already. 4G won’t replace the millions of existing GSM base stations with similar quantities.”
I think antenna hardware and technology are overlooked in the most wireless markets as one of the more vital components of the system. Antenna articles are one of the most submitted types of articles we receive at Microwave Journal but few antenna manufacturers advertise or seem to be active at shows with the exception of the Satellite show.

Strategy Analytics: Compound Semiconductor Market Cools Down
Strategy Analytics reported that after a strong rebound in the first part of 2010, revenue growth in the microelectronics segment of the compound semiconductor industry flattened in the final quarter. The recently published Strategy Analytics GaAs and Compound Semiconductors Service (GaAs) viewpoint, “Compound Semiconductor Industry Review January 2011: Microelectronics,” captures product, financial, contract and technology announcements for microelectronic companies such as RFMD, Skyworks Solutions, Hittite Microwave, ANADIGICS, Freescale Semiconductor, Microsemi and Cree for January 2010.
“Overall, the compound semiconductor industry rebounded strongly in 2010, thus slowing growth at some of the major suppliers in the fourth quarter should not be viewed with concern,” noted Eric Higham, Director of the Strategy Analytics GaAs and Compound Semiconductor Technologies Service. “The January announcements show significant product development activity that will serve to strengthen growth in 2011.”
Asif Anwar, Director in the Strategy Analytics Strategic Technologies Practice, added, “Results from some of the wafer suppliers were very strong and this also bodes well for growth throughout 2011.” Their viewpoint summarizes January 2011 financial, product, contract and employment developments from major GaAs and silicon suppliers addressing a variety of commercial and military applications using GaAs, GaN, SiC, and CMOS technologies.
