RFMD RF7161
The RF7161 is a quad-band (GSM850/EGSM900/DCS1800/PCS1900) GSM/GPRS, Class 12 compliant tr ansmit m odule wit h four interchangeable receive ports. The device is designed for use as the final portion of the transmitter section in a GSM8 50/EGSM900/DCS1800/PCS1900 hands et an d eli minates the n eed f or a P A-toantenna switch module matching network. The R F7161 f eatures R FMD’s l atest i ntegrated power-flattening c ircuit which s ignificantly reduces current and power variation into load mismatch.FEATURES
