AWT6264 power amp

Anadigics Inc. unveils a 4G power amplifier (PA) that delivers high output power, exceptional linearity and extremely high efficiency for mobile WiMAX applications in the 2.3-2.7GHz spectrum. The AWT6264 suits handsets, PC cards/dongles and embedded WiMAX modules, enabling them to conform to the IEEE802.16e standard. It also maximizes battery life for mobile WiMAX applications.

As the first mobile broadband wireless standard to be made available commercially, WiMAX technology is the cornerstone of networks serving mobile subscribers around the world today. In a recent research report, Maravedis Inc. estimates that the number of WiMAX subscribers will exceed 75 million by 2014. The report projects that more than 100 million mobile WiMAX enabled devices will ship in that same year.

Glenn Eswein, director of product marketing for Anadigics reports that "Global WiMAX roll-outs will dramatically increase the demand for broadband wireless subscriber products, with battery life being a key differentiator in the market. Our AWT6264 delivers industry-leading levels of power efficiency to manufacturers without compromising RF performance or operating bandwidth."

The wide 2.3-2.7GHz operating bandwidth of the AWT6264 enables OEMs to serve multiple geographies with a single device. In addition, the 4mm x 4mm x 1mm device, which includes fully-matched RF ports, an integrated output power detector and an integrated step attenuator, supports faster product development cycles and requires less PCB space than more discrete solutions.

Joe Cozzarelli, director of Anadigics' wireless infrastructure and WiMAX product development, adds, "This new power amplifier module offers +25dBm output power, together with the linearity and spectrum mask performance required by service providers operating in the 2.5GHz spectrum. The performance of the AWT6264 enables a class of mobile devices that will provide the consumer with a rich wireless broadband experience."

Other features of the AWT6264 include that it typically contributes 2.5 percent EVM; it provides 30dB of RF gain; operates with a typical power-added efficiency of 24 percent; and integrates a step attenuator and an output power detector.

The AWT6264 is sampling now.
