SKY77518-21 Overview
The SKY77518-21 is a transmit and receive front-end module (FEM) with Integrated Power Amplifier Control (iPAC™) for dual-band cellular handsets prising GSM900 and DCS1800 operation. Designed in a low profile, pact form factor, the SKY77518-21 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 operation.
