Manufacturer's part number :


Manufacturer Skyworks


Description :

SKY77549 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-to receive 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 four dedicated high-linearity ports.
