Abstract: This paper presents a 0.32 THz high-resolution radar system for short-range applications. It utilizes a homodyne FMCW radar architecture based on a low-cost SiGe HBT chip-set. It is implemented in a 0.13-μm SiGe engineering technology version with cutoff frequencies fT /fmax of 300/350 GHz and offers lens-integrated on-chip antennas. The measured maximum radiated power of the packaged transmitter is -5 dBm (14 dBm EIRP) at 0.311 THz. The 6-dB operational bandwidth of the chip-set is 27 GHz around the center frequency of 0.325 THz. The conversion gain of the receiver including antenna efficiency is -16 to -8 dB and its noise figure is 30-37 dB over the operational bandwidth. The FMCW radar functionality is demonstrated in a face-to-face chip-set configuration.
