Abstract

This paper presents a three-stage 2-W Ka-band power amplifier (PA) operating from 24 to 28 GHz. The PA is designed using a commercially available 0.15 μ m GaAs pHEMT technology. It employs various matching network types, including cluster, bus-bar, and T-type networks. Under a 4 V supply voltage, the simulated PA exhibits a large-signal gain of more than 16 dB and achieves a saturated output power exceeding 2 W, with a power-added efficiency (PAE) exceeding 24% at the 3 -dB compression point. The small-signal gain has a flat response with less than ± 1 ripple. The input and output return losses are lower than -6 dB and -12 dB, respectively. The occupied chip area is 7.3
