Anadigics launches 4G power amplifier for mobile WiMAX

GaAs-based wireless and broadband communications component maker Anadigics Inc of Warren, NJ, USA has made available samples of a 4G power amplifier (PA) that delivers typical error vector magnitude (EVM) of 2.5% at +25dBm linear output power and typical power-added efficiency of 24% for mobile WiMAX applications in the 2.3-2.7GHz spectrum. RF gain is 30dB.

Developed for use in handsets, PC cards/dongles and embedded WiMAX modules, the AWT6264 enables high-performance mobile devices that conform to the IEEE802.16e standard and maximizes battery life for mobile WiMAX applications.

As the first mobile broadband wireless standard to be made available commercially, WiMAX technology is currently the cornerstone of networks serving mobile subscribers worldwide, says Anadigics. In a recent research report, Maravedis Inc estimated that the number of WiMAX subscribers will exceed 75 million by 2014, when more than 100 million mobile WiMAX-enabled devices will be shipped.

“Global WiMAX roll-outs will dramatically increase the demand for broadband wireless subscriber products, with battery life being a key differentiator,” says Glenn Eswein, Anadigics’ director of product marketing.

The AWT6264’s wide 2.3-2.7GHz operating bandwidth enables OEMs to serve multiple geographies [USA, Russia, Taiwan, Japan, South Korea and Malaysia] with a single device. In addition, the 4mm x 4mm x 1mm device - which incorporates fully matched RF ports, an output power detector and a step attenuator - supports faster product development cycles and requires less PC board space than more discrete solutions.

“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,” says Joe Cozzarelli, director of Wireless Infrastructure and WiMAX product development. “The performance of the AWT6264 enables a class of mobile devices that will provide the consumer with a rich wireless broadband experience,” he adds.
