SKY77554-21
Overview
SKY77554-21 is a transmit and receive Front-End Module (FEM) with Integrated Power Amplifier Control (iPAC™) for Dual-band cellular handsets comprising GSM850/900 and DCS1800/PCS1900 operation. Designed in a low profile, compact form factor, the SKY77554-21 offers a complete Transmit VCO-to-Antenna and Antenna-to-Receive SAW filter solution.
- High efficiency - 42% (GSM850) - 42% (GSM900) - 42% (DCS1800) - 41% (PCS1900)
- Low transmit supply current - 1.36 A (GSM850) - 1.36 A (GSM900) - 0.86 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
- RF switch affords high linearity, low insertion loss, and 0 V DC on Rx ports
- Small, low profile package - 6 mm x 6 mm x 0.9 mm - 28-pad configuration
