ANADIGICS, a provider of integrated radio frequency (RF) solutions, has designed a new highly efficient and linear power amplifier for use in WiMAX (News - Alert) customer premises equipment (CPE) and small cell infrastructure solutions.

According to the company, the ANADIGICS' AWB7221 is the most power-efficient PA available for WiMAX CPEs, and also enables 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. The device's excellent 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 is designed for WiMAX and LTE interfaces operating in the 2.30 GHz to 2.70 GHz band, the AWB7221R delivers up to +28 dBm (News - Alert) of WiMAX power with exceptionally low EVM. It operates from a convenient +4.0 V supply and provides more than 30 dB of gain with a P1dB of +35 dBm.  

The AWB7221R is a highly isolated, fully matched, Multi-Chip-Module (MCM) designed for picocell, femtocell, and customer premises equipment (CPE) applications where stringent linearity and high power requirements are necessary to meet the extremely demanding needs of small cell infrastructure architectures. 

The device is manufactured using an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability and ruggedness. The self-contained 7mm x 7mm x 1mm surface mount package incorporates advanced matching networks optimized for output power, efficiency, and linearity in a 50 ohm system. 

Joe Cozzarelli, senior director of broadband RF product line at ANADIGICS, stated that 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. Its 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. 

ANADIGICS' AWB7221 power amplifier has been an optimal solution for current and next-generation CPEs and small cell base stations for 3G and 4G networks. Engineering samples are available upon request.
