Abstract This work presents a balanced power amplifier (PA) featuring a time-varying output matching network designed to suppress unwanted reflections and couplings in phased array and MIMO systems. By leveraging lossy non-reciprocal phase shifters in an indirect infinite loop, the architecture minimizes transmission loss while maintaining perfect isolation. Fabricated using a 22nm CMOS SOI process, the proposed PA achieves IP1dB variation within ±0.43dB across 3:1/2:1 VSWR contours and bandwidth (BW). The rapid adoption of cm-wave and mm-wave wireless technologies, including satellite communications (SATCOM) and emerging 5G/6G systems, drives the demand for highly reliable, large-scale phased arrays and massive-MIMO systems. PAs play a crucial role in determining key system figures of merit (FoMs) such as output power, efficiency, signal quality, and spectral purity. Large arrays exhibit two inherent challenges: voltage standing
