In this paper, a VCDRO(Voltage Control Dielectric Resonator Oscillator) applied to FMCW(Frequency Modulated Continuous Wave)Radar as stable source is implemented and constructed with a MESFET(Metal-semiconductor Field-Effect Transistor) for low noise, a dielectric resonate. of high frequency selectivity, and high Q varator diode to obtain a good phase noise performance and stable sweep characteristics. The designed circuits is simulated thrash harmonic balance simulation technique to provide the optimum performance. The measured result of a fabricated VCDRO shows that output is 2.22§¼m at 12.05GHz, harmonic suppression -30§¼c, phase noise -130§¼c at 100KHz offset, and sweep range of varator diode ¡¾18.7MHz, respectively. This oscillator will be available to FMCW Radar.
