SKY77531 Overview
The SKY77531 is a transmit and receive front-end module (FEM) with Integrated Power Amplifier Control (iPAC™) for quad-band cellular handsets prising GSM850/900 and DCS1800/PCS1900 operation. Designed in a low profile, pact form factor, the SKY77531 offers a plete Transmit VCO-to-Antenna and Antenna-to-Receive SAW filter solution. The FEM also supports Class 12 General Packet Radio Service (GPRS) multi-slot...
