A 223–276-GHz Cascadable FMCW Transceiver in 130-nm SiGe BiCMOS for Scalable MIMO Radar Arrays

Abstract
https://ieeexplore.ieee.org/document/10147390
Device
Monostatic frequency modulated continuous wave (FMCW) radar transceiver front end on a 2.7 mm2 130 nM SiGe BiCMOS chip.
Spectrum
223 – 276 GHz
Novelty
The cascadable injection-locking feedthrough technique makes the TRX suitable for massive MIMO antenna arrays in a daisy-chain topology.
Performance
Range profile > 100 m, 3 mm range resolution at 53 GHz modulation BW; 3.1 dBm TX out with 41 GHz 3 dB bandwidth at 240 GHz; 27dBm EIRP at 240 GHz with the on-chip antenna coupled with a Si lens; 18.7 dB RX SSB NF at 255 GHz, 20.7 dB NF average; 504.1 mA at 3.3 VDC power consumption.
