20.7 An Ultra-Compact D-Band Transceiver Front-End Based on a Common-Gate Bidirectional Amplifier Achieving 11.2dBm TX $P_{\text{sat }}$ and 8.2dB RX Average NF for an Area-Constrained 2D Beamformer AiP
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$P_{\text{sat }}$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$0.08 \text{mm}^{2}$.
