The RF3140 represents the second generation of RF Micro Devices' PowerStar family of PA modules, all of which feature power control functionality based on collector control - the leading integrated method of power control for GSM PAs. the RF3140 is a high-efficiency quad-band power amplifier (PA) module. The device eliminates the need for directional couplers, detector diodes, power control ASICs and other power control circuitry while providing customers the benefits of reduced component count, improved production yield, simplified phone calibration and faster time-to-market.
The RF3140 is designed for use as the final RF amplifier in single- and multiband GSM 850, EGSM, DCS and PCS handheld digital cellular equipment and other applications in the 824 to 849 MHz, 880 to 915 MHz, 1710 to 1785 MHz and 1850 to 1910 MHz bands. The module is available in a small 10 x 10 mm leadless chip carrier.
