This letter presents a 140-GHz frequency-modulated continuous-wave (FMCW) radar sensor for automotive applications. The monolithic microwave integrated circuit (MMIC) inside of the sensor features one transmit (TX) and one receive (RX) channel as well as the possibility to apply binary phase shift keying (BPSK) modulation to the transmitted signal. The chip is bonded on a printed circuit board (PCB) that features substrate integrated waveguides (SIWs) to minimize losses in the signal distribution. It provides rectangular waveguide (RWG) outputs for the <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$D$ </tex-math></inline-formula> -band to facilitate the connection of measurement equipment and antennas. The complete sensor system is controlled by a backend board that is connected via pin headers on top of the RF board with the bonded chip.
