RF3228 Quad-Band GMSK Polar EDGE TxM, 2 Rx AND 3 UMTS Switch Ports 

The RF3228 is a high-power, high-efficiency transmit module with integrated power control, an integrated pHEMT front end switch, and harmonic filtering functionality. This device is self-contained with 50Ω input and output terminals with no external matching circuits required. The device is designed for use as the last portion of the transmit chain in GMSK Polar EDGE architectures in GSM850, EGSM900, DCS, and PCS handheld digital cellular equipment where UMTS pass-through ports are needed. The RF3228 high performance transmit module offers mobile handset designers a compact, easy-to-use, front end solution for multimode, multi-band systems.
