A complete circularly polarized 210-270-GHz frequency-modulated continuous-wave radar with a monostatic homodyne architecture is presented. It consists of a highly integrated radio-frequency transceiver module, an in-house developed linear-frequency chirp generator, and a data acquisition chain. The radar front end featuring a fundamentally operated ×16 multiplier-chain architecture is realized as a single chip in 0.13-μm SiGe heterojunction bipolar transistor technology with a lens-coupled… CONTINUE READING
