Abstract

A standard-compliant integrated quad-band GSM/EDGE radio frequency power amplifier for 824-915MHz and 1710-1910MHz has been realized in a 0.35-mum SiGe-Bipolar technology. The chip integrates two single-ended 3-stage power amplifiers and a bias-control circuit for power control, band select and mode dependent quiescent currents. At 3.3 V a saturated output power of 35.9 dBm is achieved at 830 MHz and 32.3 dBm at 1710 MHz. The respective peak PAE is 56 % for low-band and 44 % for high-band.
