Skyworks Solutions unveiled a highly integrated 2.5-GHz WiMAX front-end module (FEM), model SKY77258, at the recent CTIA show. The FEM is designed for WiMAX handsets and terminals. It incorporates a reliable InGaP HBT power amplifier, pHEMT switch, coupler, detector, controller, baluns, low-noise amplifiers (LNAs), and matching components in a 36-pin, 8 x 10 mm RoHS-compliant multichip module (MCM). The FEM provides +24 dBm linear output power at the switch output with output power at 1-dB compression of more than +35 dBm to support the high peak-to-average ratio (crest factor) needed in multicarrier WiMAX systems.
