  Abstract

In this paper, we reported on a high performance waveguide VCO(voltage controlled oscillator) for FMCW applications. The waveguide VCO consists of a GaAs Gunn diode, a varactor diode, and two bias posts with low pass filter(LPF). The cavity is designed for fundamental mode at 47 ㎓ and operated at second harmonic of 94 ㎓ center frequency. The developed waveguide VCO has 1.095 ㎓ bandwidth, 590 ㎒ linearity with 1.69% and output power from 14.86 to 15.93 ㏈m. The phase noise is under -95 ㏈c/㎐ at 1 ㎒ offset.
