Abstract

Double-heterojunction InGaAs pseudomorphic HEMTs (high electron mobility transistors) with a 0.25 mu m gate-length have been integrated into a three-stage power amplifier MMIC (monolithic microwave integrated circuit) designed for the 34-36 GHz band. This first pass design exhibited a peak small-signal gain of 30 dB, a minimum output power of 200 mW with 20 dB associated gain, a power-added efficiency of greater than 18%, and a return loss of greater than 14 dB over the entire band. This performance was measured with the MMIC operating from a single 6 V DC supply.<>
