EDGE RF Subsystem

Skyworks offers a highly integrated radio subsystem for quad-band EDGE handset, base stations and cellular repeaters. The subsystem supports GSM850, EGSM900, DCS1800, and PCS1900 applications, and combines a fully programmable quad-band transceiver with a transmit/receive FEM. The FEM integrates pHEMT switches, GaAs-based power amplifiers, couplers, and other discrete matching components into a single multi-chip module.

The dual-chip RF subsystem solutions save significant space, cost, and design cycle time. The subsystems provide excellent linearity, blocker performance, dynamic range, and output power required by handset manufactures, cellular operators, carriers, and equipment manufacturers of global femtocell base stations and cellular repeaters.

The EDGE RF Subsystem features:
  • Quad-band transceiver that supports the GSM850, EGSM900, DCS1800, and PCS1900 bands
  • FEM providing a complete transmit path from transceiver to antenna with 50 Ohms input/output matching
  • Excellent linearity, blocker performance, noise figure, and dynamic range
  • Lower BOM cost and compact design

The EDGE RF Subsystem consists of:
  • SKY65330 Transmit/Receive FEM (For infrastructure applications) - highly integrated FEM with two PA blocks, one for the GSM/EGSM bands and the other for the DCS/PCS bands.
  • SKY74218 RF Transceiver – Highly integrated, quad-band RF transceiver with DigRF interface.
  • SKY77524 T/R Front-End Module (For handset applications) – Quad-band Front-End Module with integrated coupler, pHEMT RF switch, and separate GSM850/EGSM900 and DCS1800/PCS1900 PA blocks provides a complete DigRF interface transmit path from transceiver output to antenna.
