Full MMIC millimeter-wave front end for a 76.5 GHz adaptive cruise control car radar

This paper describes the development for volume production of a millimeter-wave front-end for a 76.5 GHz Adaptive Cruise Control (ACC) car radar. The ACC radar is based on a Frequency Shift Keying (FSK) concept. The millimeter-wave module is fabricated using a chip-set composed of only 3 MMICs: a local oscillator chip, a power transmitter chip and a down-converter receiver chip.
