FX5196 is a transmit and receive Front-End Module (FEM) with integrated power amplifier control designed in a low profile, compact form factor for quad-band cellular handsets comprising GSM850/GSM900 and DCS1800/PCS1900 operation. FX5196 supports quad-band GSM/GPRS/EDGE, with matched 50-Ohm RF input and output ports. The FEM also supports UMTS applications through 14 high linearity TRx ports.

The FX5196 consists of a CMOS power amplifier, a SOI SP16T antenna switch, and a CMOS controller chip. The CMOS power amplifier can work in saturated mode for GMSK, as well as in linear mode for EDGE 8PSK operations. With delicately designed internal low-pass filters, this module provides excellent harmonic suppressions in all operating frequencies. The embedded SP16T switch enables up to 14 TRx ports with low insertion loss and high linearity, including 1 ultra-low insertion loss ports. The FX5196 also guarantees robust 8kV high ESD protection for the antenna port. The integrated multi-functional CMOS controller regulates the supply voltage to ramp the output RF power in saturated GSM/GPRS operation, flattens the power variation under battery voltage, ambient temperature, mismatch circumstances, optimize bias voltage for multi-mode operations, and powers up the SOI switch with internal voltage regulators.

Housed in a compact 5.5mmx5.3mmx0.74mm package, the FX5196 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
