Analysis of an Impedance‐Adaptive W‐Band GaN MMIC Power Amplifier
IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.This paper presents a W‐band GaN MMIC power amplifier with an integrated reconfigurable matching network implemented in a 40‐nm GaN‐on‐SiC process. The three‐stage PA achieves 18.1 dB gain and 25.3 dBm output power at 77 GHz, demonstrating the feasibility of embedding reconfigurable elements in millimetre‐wave PAs.
