Anadigics adds PA for 3.5GHz WiMAX in CPE and femtocells

Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has launched the AWB7230 power amplifier (PA) module, a fully matched, multi-chip-module (MCM) that enables network performance across all the 3.5GHz WiMAX bands for use in Customer Premises Equipment (CPE) and femtocells.

Manufactured using InGaP HBT MMIC technology, the AWB7230 meets WiMAX spectrum mask requirements while delivering what is claimed to be exceptional linear RF power, and can serve as the final-stage amplifier in the transmit chain of either a CPE or femtocell. Covering the full 3.3–3.8GHz band, the device supports 3.5GHz WiMAX networks worldwide, and provides what is claimed to be the highest power efficiency available for such applications (16% power-added efficiency at rated output power, delivering up to +29dBm of WiMAX power with low EVM, and providing more than 30dB of RF gain). The AWB7230 also incorporates RF matching networks optimized for output power, efficiency and linearity in a 50Ω system.

The AWB7230 complements Anadigics’ AWB7221 PA, which was launched last October to enable CPEs and femtocells operating in the 2.5GHz WiMAX bands. With the new PA, Anadigics now supports the two predominant sets of WiMAX frequency bands used around the globe.

“As WiMAX and other 4G technologies continue to emerge, Anadigics is responding to customer demands for high-performance PA modules that enable exceptional consumer and infrastructure solutions,” says Joe Cozzarelli, senior director, Broadband RF Products. “With the AWB7230, Anadigics continues to expand its product portfolio and demonstrate industry-leading performance by providing wideband coverage at high linear power levels, and with best-in-class power efficiency,” he claims.

WiMAX CPEs provide an alternative to DSL and cable modems, and also play a key role in the transition to 4G, by offering consumers high-speed wireless connectivity for their homes, shops or businesses. According to industry organization WiMAX Forum, nearly 600 WiMAX (fixed and mobile) networks have been deployed in 149 countries, with network coverage forecasted to be available to more than 1 billion potential subscribers worldwide this year.

Anadigics claims that the AWB7230 is an optimal solution for current and next-generation WiMAX CPEs and small-cell base-stations. Engineering samples are available now for qualified opportunities.
