            Abstract : 
In this paper, a Ku band voltage controlled oscillator with a frequency range of 220MHz is presented. By changing the traditional structure, combining the resonance with the active component through direct coupling, the oscillator becomes easier to oscillate; therefore the performance of the oscillator has been improved. The output power is 4.79dBm and 7.02dBm at 12.24GHz and 12.49GHz, respectively. The control voltage ranges from 1V to 12V. The phase noise is -66.73dBc/Hz@100KHz at 12.49GHz.
