Abstract :
A monolithic 2.5 GHz linear power amplifier for W-LAN IEEE 802.11g applications was integrated using a low cost 22 GHz fT silicon bipolar process. The three-stage power amplifier exhibits a 26 dBm output 1 dB compression point, 30 dB power gain, and 52% maximum power-added efficiency, while using a low quiescent current, of 40 mA. Thanks to an optimized linearization technique, the power amplifier is able to comply with the stringent error vector magnitude requirement of the standard up to a 21.5 dBm output power level, with a 32% power-added efficiency. The power amplifier includes advanced bias functionalities and a fully integrated average channel power detector.
