Femtocells promise to 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. To serve such emerging applications, the AWB7127 and AWB7123 power amplifiers (PAs) have been designed for use in femtocells, picocells, and in-home customer premises equipment (CPE). These PAs support complex modulation schemes, such as those used in WCDMA, HSDPA, and LTE air interfaces, by providing margin to the adjacent-channelpower (ACPR) requirements at rated output-power levels. They deliver WCDMA power to +24.5 dBm with an ACPR of -50 dBc. Operating in the most popular third-generation (3G) frequency bands, the AWB7123 supports UMTS band 2 in North America. In contrast, the AWB7127 supports band 1 in Europe, Asia, and parts of South America. The AWB7123 and AWB7127 are manufactured using an advanced indium-gallium-phosphide (InGaP), heterojunction-bipolar-transistor HBT), monolithic-microwave-integratedcircuit (MMIC) process technology that promises to deliver reliability, temperature stability, ruggedness. They incorporate RF matching networks optimized for output power, efficiency, and linearity in a 50-Ohm system. P&A: sampling now.
