A Low-Power D-Band Radar Transceiver with TL-MCR Matching Technique and Output Phase Shifting

This paper proposes a D-band frequencymodulated continuous-wave (FMCW) radar transceiver with two transmitters (TX) and two receivers (RX) fabricated in 28 nm CMOS. Transmission-line magnetic-coupled resonator (TLMCR) matching technique in local-oscillator (LO) distributor enhances the gain and reduces power consumption. D-band phase shifters are integrated into transmitters to support precise output phase shifting. The transceiver achieves a 7.6 dB noise figure, 67 dB conversion gain (CG), 13.3 dB output saturation power and $14.3 \%$ drain efficiency with 360° phase shifting. Power consumption per one transmitter and one receiver operation is 285 mW.
