SKY77518-21
Description
The SKY77518-21 is a transmit and receive front-end module (FEM) with Integrated Power Amplifier Control (iPAC™) for dual-band cellular handsets comprising GSM900 and DCS1800 operation. Designed in a low profile, compact form factor, the SKY77518-21 offers a complete Transmit VCO-to-Antenna and Antenna-to-Receive SAW filter solution.
Key Features
- High efficiency - GSM900 48% - DCS 41%
- Low transmit supply current - GSM900 1.26 A - DCS1800 0.9 A
- Internal ICC sense resistor for iPAC
- Closed loop iPAC
- 50 Ω matched Input/Output
- TX-VCO-to-antenna and antennato-RX-SAW filter RF interface
- TX harmonics below -33 dBm
- PHEMT RF switches afford high linearity, low insertion loss, and less than 20 μA supply current in receive modes
- Small outline: 6 mm x 8 mm
- Low profile: 1.2 mm
