Abstract

In this paper, a compact (8×8 mm² package size) short-range, bistatic radar sensor operating at 122 GHz is presented. The goal is to show the feasibility of a SiP solution in a low-cost Surface-Mounted-Device (SMD) package. The millimeter-wave integrated circuit is based on a SiGe-BiCMOS technology which offers an f_T of 280 GHz and f_max of 300 GHz. The setup of the radar sensor is introduced and measurement results for frequency-modulated-continuous-wave (FMCW) modulation demonstrate the performance of the radar front end. The targeted application areas are short range distance and speed measurements, which especially gain an advantage for high resolution distance measurements because of the short wavelength at mm-wave frequency. The chip occupies an area of 940 μm × 1450 μm, and dissipates a DC power of 450 mW.
