This session highlights recent advances in scalable mm-Wave to sub-THz phased-array transceivers and front-end architectures targeting high-data-rate communications and high-resolution sensing. The presented works span E-band, D-band, and frequencies beyond 200 GHz, demonstrating CMOS/SiGe and III-V HEMT implementations that push efficiency, output power density, bandwidth, and integration scalability. Key themes include wideband beam-steering transmitters, compact and reconfigurable T/R switching for TDD operation, die-to-die stitching approaches enabling wafer-scale phased arrays, and multi-channel beamforming.
