Anadigics Intros Linear Power Amplifier for WiMAX CPE, Small-Cell Infrastructure Markets

Anadigics, Inc. has introduced a new power amplifier (PA) for use in WiMAX (News - Alert) customer premises equipment (CPE) and small cell infrastructure solutions. Anadigics' AWB7221 is the power efficient PA available for WiMAX CPEs, and is also said to enable cost efficient femtocells for 3G and 4G networks.

The high linear transmit power of the AWB7221 enables CPEs with a powerful uplink that supports wide, high data rate network coverage. In addition, the device's power efficiency reduces the overall power consumption of a CPE or femtocell, leading to a reduction in system cooling requirements and less costly designs. The AWB7221 PA enhances network performance in key global WiMAX markets such as North America, Japan and Korea, and also supports new LTE (News - Alert) or TD-LTE networks in the 2.30 GHz to 2.70 GHz frequency bands.

"A growing consumer appetite for enhanced wireless broadband applications is creating more demand for customer premises and small cell infrastructure equipment that delivers faster data speeds over greater distances," said Joe Cozzarelli, senior director, Broadband RF Product Line, Anadigics (News - Alert). "Our AWB7221 PA provides a practical and effective way for service providers to answer this demand, and to continue to roll out 4G to a broader market."

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 (News - Alert), nearly 600 WiMAX (fixed and mobile) networks have been deployed in 149 countries, with network coverage forecasted to be available to 800 million potential subscribers worldwide by the end of this year.

As WiMAX and other 4G networks continue to deploy worldwide, and 3G service providers seek to enhance their network coverage, the demands for small cell base stations such as femtocells and picocells will grow tremendously. Industry analyst In-Stat (News - Alert) asserts that that small cell base stations are "vital to 4G deployment," forecasting that femtocell revenue will grow at an 83 percent compounded annual rate over the next four years, and that the number of carrier-installed metropolitan picocells will increase at a 378% compounded annual rate over the same period.
