SKY77590-51 Datasheet Tx-Rx FEM

Manufacturer: Skyworks Solutions

General Description

SKY77590-51 is a transmit and receive Front End Module (FEM) designed in a very low profile (0.9 mm) and compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation and dual-band TD-SCDMA bands 34 and 39 operation — a complete transmit VCO-to-Antenna and Antenna-to-receive SAW filter solution.

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

3G switch-through support is provided by six dedicated high-linearity ports.
