RF7161

QUAD-BAND GSM850/EGSM900/DCS1800/

PCS1900 TRANSMIT MODULE

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. T his tra nsmit mo dule

builds upon RFMD’s leading power amplifier with PowerStar® integrated power control technol-

ogy, pHEMT switch technology, and integrated transmit filtering for best-in-class harmonic per-

formance. T he re sults ar e hi gh p erformance, re duced so lution si ze, an d ea se of

implementation. 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-to-

antenna 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. Additionally, a VBATT tracking feature is

incorporated to maintain switching performance as supply voltage decreases. The RF7161 also

integrates an ESD filter to provide excellent ESD protection at the antenna port. The RF7161 is

designed to provide maximum efficiency at rated POUT.
