Abstract

In this paper, a 26-31 GHz power amplifier (PA) is presented using a 0.15-μm GaAs pHEMT process for millimeter-wave communication applications. To extend the bandwidth, the output matching of the presented PA is designed using pre-matching technique. The chip size of the PA is 2×1.8 mm2. The measured maximum small-signal gain is 11.5 dB with a 3-dB bandwidth from 26 to 31 GHz. When the frequency is 29 GHz, the measured output 1-dB compression point (P1dB) and saturation power (Psat) are higher than 26 and 28 dBm, respectively, and the measured maximum power added efficiency is 10%.
