FX5566B

FX5566B power amplifier module (PAM) is designed for quad-band GSM/GPRS/EDGE (GSM850/EGSM900/DCS1800/PCS1900) application. The PAM consists of a GaAs HBT power amplifier and a CMOS controller chip. The CMOS controller provides PA bias and product identification read-back capability and is fully programmable through the RF Front-End Mobile Industry Processor Interface (RFFE MIPI). The PAM works in saturated mode for GMSK, as well as in linear mode for GMSK & EDGE 8PSK opera-tions. With the delicately designed internal low-pass filters, this module provides excel-lent harmonic suppressions in all operating frequencies.
