Abstract An ultra-compact D-band transceiver based on a common-gate bi-directional amplifier is presented in a 45nm RFSOI process for an area-constrained 2D beamformer antenna-inpackage. By employing a switchless symmetric inter-stage matching network and compact, low-loss reconfigurable input/output networks, the transceiver front-end achieves a TX peak Psat of 11.2dBm at 135GHz and an average RX NF of 8.2dB over 129 to 145GHz. The active chip area, excluding pads, is only 0.08mm2. The continuous growth in demand for wireless data necessitates the utilization of the Dband spectrum (110 to 170GHz). However, the limited transistor performance of silicon-based RFICs and the severe path loss at such high frequencies require the development of large-scale D-band phased arrays. For a compact phased-array transceiver module, the transmitter (TX) and receiver (RX) circuits can share an antenna, typically
