GaN Heading Commercial?
The gallium nitride (GaN) device market will grow at an annual rate of nearly 29% to $178 million in 2015, according to the “GaN Microelectronics Market Update 2010-2015” report from Strategy Analytics. The percentage of GaN revenue derived from its primary customer (the defense industry) will shrink from 98% in 2010 to 67% in 2015, and revenue growth rates for GaN devices in wireless infrastructure, high-power electronics, and CATV/VSAT will exceed 100%.
LTE’s Growing Fast, But…
LTE is expected to constitute a small percentage of the overall cellular subscriptions in the coming years, according to a report from Pyramid Research. The company forecasts that LTE will have 592 million subscriptions in 2016, 7.3% of all cellular subscriptions. Thirty-five wireless carriers have thus far introduced LTE networks and about 200 LTE devices are now available.
InStat’s 2011 “Top Mobile Developments”
Market research firm In-Stat includes in its top mobile stories of 2011 Nvidia’s rollout of formidable mobile processors, Intel’s dramatic reorganization focusing on mobile technology, Google's introduction of Google Wallet (based on Near -Field Communications technology), Windows 8, Amazon’s Kindle Fire, AT&T’s failed acquisition of T-Mobile from Deutsche Telekom, the close partnership of Nokia and Microsoft, and Google's $12.5 billion cash acquisition of Motorola Mobility.
Weak LTE? Try This
To make LTE live up to its high speeds, you need decent signal strength. The Sleek 4G from Wilson Electronics covers Verizon's 2G and 3G networks at 1800 to 1900 MHz as well as its 700 MHz LTE network. The company claims the device delivers 20 times the signal strength of antennas installed in smartphones and tablets. It can be attached to the roof of a car, in an office, and there will be an outdoor antenna kit for mounting anywhere. When available in the second quarter, projected cost is $150.
A Message from
The RF and microwave industry owes a debt of thanks to LightSquared for getting filters mentioned in news
stories in print and online. Fighting to save its life, the company accused GPS receiver manufacturers of being
too cheap to add a “five cent filter” to their designs that would eliminate interference from its proposed (and
likely doomed) satellite/terrestrial LTE network. The argument was of course ridiculous since GPS has never
faced a threat in its spectral region since it was first deployed. Nevertheless, it grabbed headlines.
Where We’ll Be Exhibiting in 2012
Our experience at both the International Microwave Symposium and MILCOM has always been positive and 2011 was no exception. Both of these shows continue to draw attendees from throughout the world – and Anatech will be there in 2012!
The International Microwave Symposium heads to Montréal in 2012 and Anatech Electronics will be exhibiting there, at the Palais des Congrès de Montréal from June 19 to 21. Our booth is 315.
New Products of Interest
Satcom Ku-band Duplexer/Low-Noise Amplifier
The compact Model AE14625-15250DB5370-LNA for satcom terminals combines a duplexer and low-noise amplifier, reducing the size required to house both components. The duplexer’s transmit frequency is 14.4 to 14.83 GHz, its receive frequency is 15.15 to 15.35 GHz, and it will handle 150 W CW. The LNA has a noise figure of 3.5 dB, gain of 20 dB, and P1dB RF output of 15 dBm. Insertion loss of the entire unit is less than 2.5 dB, it operates from -20° to +85° at altitudes to 30,000 ft., and meets shock and vibration requirements of MIL-STD-810F.
Multiband Combiners for Wireless Systems
Our family of band combiners and dividers allow a single antenna to serve multiple bands and radios, reducing cost and complexity. They can combine or divide 2 to 6 wireless bands in any combination including GSM, PCS, WiMAX, LTE, and other custom combinations by request. Check them out here.
