Abstract

In this paper, a Ka‐Band 24‐dBm AlGaAs/InGaAs/GaAs PHEMT MMIC power amplifier is demonstrated. This three‐stage amplifier is designed to fully match for 50Ω input and output impedances. With 4 V and 250‐mA DC bias, we achieve 15‐dB small‐signal gain, 24 dBm P~−1dB~, 24.3% PAE, and better than 10‐dB input return loss from 31 to 37 GHz. © 2004 Wiley Periodicals, Inc.
