SKY77531 - TX-RX IPAC FEM Quad-Band GSM/GPRS

General Description

The SKY77531 is a transmit and receive front-end module (FEM) with Integrated Power Amplifier Control (iPAC™) for quad-band cellular handsets comprising GSM850/900 and DCS1800/PCS1900 operation.

Key Features

  • High efficiency - 48% (GSM850/900) - 41% (DCS1800/PCS1900).
  • Low transmit supply current - 1.26 A (GSM850/900) - 0.90 A (DCS1800/PCS1900).
  • Internal ICC sense resistor for iPAC.
  • Closed loop iPAC.
  • 50 Ω matched Input/Output.
  • TX.
  • VCO-to-antenna and antenna-to-RX-SAW filter RF interface.
  • TX harmonics below.
  • 33 dBm.
  • PHEMT RF switch affords high linearity, low insertion loss, and less than 20 μA supply current in rec.
