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.
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.
