摘要：

In this paper, We have designed and fabricated the waveguide voltage controlled oscillator (VCO) at 94 GHz, which consists of a GaAs Gunn diode, a varactor diode, and two bias posts with low pass filter (LPF), and a Magic Tee for FMCW radar. The cavity is designed for a fundamental mode at 47 GHz and operated at second harmonic of 94GHz center frequency. The fabricated VCO has 640 MHz bandwidth, 505MHz linearity with 2%. The VCO operates at 93.9 GHz with phase noise of -102.79 dBc/Hz at I MHz offset and power of 11.34 dBm. The W-band VCO has phase noise better than -100 dBc/Hz.
