Device
Joint Radar – Communication (JRC) Transceiver Utilizing Reconfigurable Dual-Mode Gilbert Cells in 65 nm CMOS Technology
Spectrum
60 GHz
Novelty
Dual-mode Gilbert cells are applied in a highly reused architecture to amplify the LO in radar mode for a wideband chirp directly from the LO chain to improve range resolution, and applied as conventional upconversion mixers in communication mode to modulate the baseband (BB) communication data.
Application
Integrated sensing and communications (ISAC) applications in 6G networks.
Performance
16 dBm saturated output power (OP); 11 dBm OP1dB; 5.8 dB minimum RX noise figure (NF) . >4GHz transmitted chirp bandwidth; <3.75 cm range resolution; 1 µm vibration displacement detected in radar mode. >7 Gb/s (16 QAM) over the air demonstrated in comunication mode.
