Anadigics' high linearity power amplifiers for femtocells and picocells

Anadigics has introduced two new power amplifiers (PAs), AWB7127 and AWB7123, designed for use in femtocells, picocells and in-home customer premises equipment (CPE).

Femtocells and picocells solve the problem of weak wireless broadband signals in homes and offices by allowing mobile devices to connect to their carrier's network through a high-speed Internet backhaul link.

The AWB7127 and AWB7123 supports complex modulation schemes, such as those used in WCDMA, HSDPA and LTE air interfaces, by providing margin to the adjacent channel power (ACPR) requirements at rated output power. The AWB7123 supports UMTS band 2 in North America and the AWB7127 supports band 1 in Europe, Asia and parts of South America. These PA modules manufactured using InGaP HBT MMIC technology can deliver up to +24.5 dBm of WCDMA power with an ACPR of -50 dBc and it also incorporates RF matching networks to optimize its output power, efficiency, and linearity in a 50 ohms system. These highly integrated PA modules have been designed for incorporation into small-cell base station platform. The high performance designs are standards-flexible, and support products developed for networks in which an evolution to LTE will occur.

"Femtocells are a fundamentally new approach to mobile network architecture, and offer an attractive option for upgrading the existing network infrastructure as well as deploying the latest 4G technologies," said Joe Cozzarelli, Senior Director, Broadband RF Product Line, Anadigics. "We've drawn on our extensive experience in the design and development of power amplifiers for both mobile handsets and broadband cable infrastructure to balance the appropriate level of integration, performance and reliability in a cost-effective way. Our design approach provides the flexibility to support multiple standards with one device, making the job of the femtocell designer easier."
