20.4 An Ultra-Compact, Inherently Resilient FR3 Source-Follower Power Amplifier with 4:1 VSWR Resilience and RIMD Immunity for Large-Scale SATCOM and 6G Phased Arrays
Abstract
This paper presents a source-follower power amplifier (PA) designed to combat high VSWR and reverse intermodulation distortion (RIMD) in phased arrays. Its inherently low output impedance enables conjugate matching and robust resilience to load variations, mitigating degradation from antenna mismatches up to 4:1 VSWR. The design maintains strong largesignal performance without compromise, proving its suitability for compact, calibration-free integration in large-scale SATCOM and 6G systems.
