Low RMS-error and broadband phase shifters are essential building blocks for beamforming. This session features four broadband phase shifters spanning 8–110GHz, 91–125GHz, 8–28GHz, and 24–30GHz, all implemented in silicon (22nm and 65nm CMOS/FD-SOI). Highlights include a 10-bit distributed vector-summing PS with <0.22dB RMS gain error and <1.99° RMS phase error, a 91–125GHz beamforming receive channel with sub-dB gain and sub-few-degree phase error, a wideband all-passive variable gain phase shifter with calibration-free gain control, and a compact 7-bit passive hybrid achieving <1.1°/<0.61dB RMS errors. Also included is a bi-directional reflection-amplifier phase shifter for ultra-low-power RIS enabling large-scale beyond-5G deployments.
