Quad-band GSM/GPRS/EDGE PA Module

The FX5566A power amplifier module (PAM) is designed for quad-band GSM/GPRS/EDGE (GSM850/EGSM900/DCS1800/PCS1900) application. The FX5566A 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 operations. With delicately designed internal low-pass filters, this module provides excellent harmonic suppressions in all operating frequencies.


Housed in a compact 3.5mmx3.5mmx0.75mm package, the FX5566A greatly lowers the front-end complexity of multi-mode GSM/GPRS/EDGE solution,facilitates the customer’s implementation, and saves board room and cost significantly.
