A platform approach to phased-array architecture was investigated. The platform consists of reusable 15-32GHz transceiver cores in 45nm SOI CMOS and 15-100GHz beamforming extenders in SiGe. The receiver core was realized as a four-phase passive mixer-first receiver, operating across 6-33GHz, achieving a measured 5-9dB noise figure, 20dB conversion gain, -12 to -3dBm input-referred compression point, and consuming 110-220mW. This meets program goals and is the highest and broadest operating frequency for a passive mixer-first receiver. The transmitter core was realized as an active Gilbert-cell mixer and balanced power amplifier. In simulation, the transmitter core achieves 17-19dBm output compression and operates across 20-33GHz. This hardware is still in fabrication. Three extenders were realized, including a measured 28GHz four-element transceiver array, a measured 60GHz four-element receiver array, and a simulated 80GHz single-element transmitter, still in fabrication. Full platform demonstrations including the core plus the extenders are in progress.
