ANADIGICS, Inc., a company specializing in radio frequency integrated circuit (RFIC) solutions, has launched a new power amplifier module, AWB7230, designed for use in WiMAX Customer Premises Equipments and femtocells.

"As WiMAX (News - Alert) 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," Joe Cozzarelli, senior director, Broadband RF Products, ANADIGICS said in a statement.

"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," Cozzarelli added.

ANADIGICS' new device is said to be a fully-matched, multi-chip-module that can enable network performance across all the 3.5 GHz WiMAX bands.

The company revealed that the new AWB7230 is designed to meet WiMAX spectrum mask requirements and is capable of serving as the final stage amplifier in the transmit chain of either a CPE or femtocell. 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. Covering the full 3.3 GHz to 3.8 GHz band, this device is said to support 3.5 GHz WiMAX networks worldwide, and also provide the highest level of power efficiency available for such applications.

The AWB7230 is believed to complement ANADIGICS' AWB7221 PA, which was released last year to enable CPEs and femtocells operating in the 2.5 GHz WiMAX bands.

Key facts noted by the company about AWB7230 is that it is manufactured using an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. It delivers up to +29 dBm (News - Alert) of WiMAX power with exceptionally low EVM and provides more than 30 dB of RF gain. Moreover, it can operate with 16 percent power-added-efficiency at rated output power and support all the 3.5 GHz WiMAX bands, from 3.3 GHz to 3.8 GHz. Above all, it is said to incorporate RF matching networks optimized for output power, efficiency, and linearity in a 50 Ω system.

In related news, TMCnet reported plans of ANADIGICS to exhibit at the 2011 Mobile World Congress (News - Alert), Feb. 14-17, in Barcelona, Spain. At the booth, ANADIGICS said it will demonstrate why advanced reference designs and leaders in mobile communication equipment are specifying ANADIGICS solutions in their 3G and 4G designs.
