Abstract

In this paper, a low cost and compact K-band radar front-end, which can output FMCW signals in 23.76~24GHz with phase noise about -80dBc/Hz@10KHz and spurious suppression higher than 60dBc is designed. The frequency source part achieves the purposes of low power consumption and miniaturization with 2.8W DC power consumption and 58×53×19mm³ dimension. The results of close loop experiments (3m, 4m, 5m, 7m, 8m, 9m) indicate the system can realize the function of measuring distance, and the measurement accuracy reaches the design goal.
