This technical session highlights state-of-the-art power amplifier (PA) architectures for D-band and mmWave applications in bulk CMOS and FD-SOI. Key innovations include a D-band variable-gain PA using Guanella transformers for 36% fractional bandwidth (FBW) and 20 Gb/s 16-QAM signaling, alongside ultra-compact 145 GHz PAs featuring adaptive back-gate biasing and diode-based linearization. Ultra-broadband performance is showcased through a 9.5–40 GHz linear PA utilizing compensated coupled-line transformers (126.5% FBW) and a 15.5–46.0 GHz PA with high-efficiency matching networks. Finally, a 40 GHz load-isolated Doherty PA is presented, offering enhanced VSWR resiliency and high efficiency for robust, high-speed wireless communication.
