SKY77544 Datasheet Tx-rx Fem

Manufacturer: Skyworks Solutions

Overview: PRODUCT SUMMARY SKY77544 Tx-Rx FEM for Quad-Band GSM / GPRS / EDGE – Triple-Band WCDMA Antenna Switch Support Applications • Quad-band cellular handsets encompassing - Class 4 GSM850/900 - Class 1 DCS1800 PCS1900 -.

General Description

SKY77544 is a transmit and receive Front End Module (FEM) designed in a very low profile (0.9 mm), compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation — a complete transmit VCO-to-Antenna and Antenna-toreceive SAW filter solution.

The FEM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation and EDGE Polar Modulation.

WCDMA switch-through support is provided by three dedicated high-linearity ports.
