Abstract
A two-stage InGaP/GaAs heterojunction bipolar transistor (HBT) power amplifier is developed for WLAN 802.11b application. This is integrated with power detector that senses input power of power stage in order to decrease output power loss of detecting. The power amplifier delivers up to 26dBm output power with the maximum power-added efficiency (PAE) of 31% including consumption of the power detector under the supply voltage of 3.3V
