A broadband MMIC power amplifier operating from 17 to 36 GHz is developed for point-to-multipoint applications using 0.25 μm AlGaAs/InGaAs/GaAs pseudomorphic high electron mobility transistor (PHEMT). The amplifier is fully monolithic, with all matching, biasing, and DC block circuitry included on the chip. Operated under 5 V power supply, the two-stage balanced power amplifier has 11 dB small-signal gain with a 3 dB bandwidth from 17 to 36 GHz. The output powers at 1 dB compression are 20 dBm at 26 and 28 GHz and greater than 23 dBm at 30.5 GHz.
