ANADIGICS Delivers 3.5 GHz Full Band Power Amplifier for Growing Mobile WiMAX Market
Responding to growing global demand for mobile WiMAX services, ANADIGICS, Inc. today introduced a new, feature-rich power amplifier (PA), the AWT6283R, designed to significantly boost the performance and efficiency of WiMAX transceivers. The AWT6283R is the industry’s first PA to deliver high linear output power, exceptional efficiency, and consistent RF performance over the full 3.3 to 3.8 GHz WiMAX frequency band. Ideal for mobile applications, the AWT6283R includes a step attenuator, a power detector and a reference voltage regulator in a small, easy-to-use package which simplifies design and saves board space.
The WiMAX market continues to gain momentum, with mobile devices all but displacing fixed-point equipment in new deployments. Commercial WiMAX networks, trial networks, and networks in development are increasing monthly. According to In-Stat, new devices drive the market, with USB dongles and mobile PCs embedding WiMAX capability available today, and WiMAX-enabled cellular handsets just around the corner.
“With the introduction of the AWT6283R, we’re expanding our product portfolio in the fast-growing WiMAX space to deliver the most efficient, high-performance components that ultimately improve the end-user experience,” said Joe Cozzarelli, director, Broadband RF Product Line for ANADIGICS. “The AWT6283R complements our existing line of WiMAX devices and offers the linearity, reliability, temperature stability and ruggedness that our customers demand.”
Key Facts and Highlights:
* ANADIGICS is a leading supplier of WiMAX power amplifiers, having
entered the market early to enable leaders like Intel who saw the
potential of WiMAX.
* The AWT6283R is optimized for operation over a 500 MHz bandwidth,
ensuring exceptional linearity and efficiency, and consistent RF
performance, across the entire 3.5 GHz WiMAX frequency band.
* Today the WiMAX Forum currently tracks 523 WiMAX deployments in
147 countries, compared to 408 deployments at the end of 2008.
* Brazil is potentially one of the world’s most dynamic WiMAX
markets, according to Infonetics. The number of WiMAX subscribers
is forecast to skyrocket from 184,000 in 2008 to almost 8 million
in 2013.
* Industry analysts also expect steady growth in WiMAX handset
sales over the next five years, particularly in emerging markets
such as South America, Russia, Eastern Europe, the Middle East
and parts of Asia where the majority of deployments are already
taking place.
* WiMAX is complementary to LTE and provides a true mobile Internet
solution. WiMAX chipset technology has moved beyond multiple
chips to single chip solutions integrating the baseband
functionality with the RF radio.
* The AWT6283R is the first 3.5 GHz device which incorporates an
impedance match on both the input and output RF ports, a
reference voltage regulator, a power detector and a step
attenuator.
* The built-in reference voltage regulator eliminates the need for
an external precision reference voltage; the built-in attenuator
allows the device to be used with any OEM’s chipset
Additional product features include:
* +25 dBm linear output power
* 21% power efficiency at +25 dBm output power
* Low quiescent current to increase transmit time and overall
efficiency
* Low leakage current in shutdown mode to increase standby time and
battery life
* Low profile 4 x 4 x 1 mm miniature surface mount package for
space-constrained applications
* RoHS Compliant Package (MSL-3, 260 degrees Celsius)
* Advanced InGaP HBT MMIC technology
Samples for ANADIGICS’ AWT6283R are available now. The device meets all industry requirements and supports mobile WiMAX systems using the IEEE 802.16e standard.
