Phase and amplitude control blocks are central to scalable phased-array beamforming, but pushing bandwidth, accuracy, bidirectionality, and integration density simultaneously remains challenging. This session highlights recent circuit innovations that deliver phase-invariant gain control, wideband vector-modulation phase shifting, and switchless bidirectional operation. The papers span ultracompact reciprocal phase-inverting architectures, broadband bidirectional amplitude–phase control for multibeam transceivers, and phase-compensated VGA designs over wide tuning ranges.
