FMCW Radar Transceiver with Dual Lens Packaging in 65-nm CMOS

140 GHz (D-Band)

Dual lens improves beam alignment by placing the TX and RX antennas at the opposite ends of the integrated TRX chip to maximize antenna separation to minimize TX-RX interference. The hyper-hemispherical lens that the chip is mounted on minimizes the excitation of undesirable substrate modes and enhances radiation efficiency and directivity.

Automotive radars, vital sign monitoring, level monitoring, occupancy detection, and gesture recognition.

9.5 dBm TX Pout, 14 dBm EIRP; 9.9 dB NF, 65 dB Conversion Gain; 32 GHz chirp BW (128-160 GHz), 6 µs chirp duration; 10 mm range resolution at 5m; 350 mW DC power consumption.
