In this paper, a voltage controlled oscillator(VCO) of core components for wireless subscriber network is designed. The type of oscillator is colpits method and the oscillator device uses a LC resonator. The product is made on FR-4 substrate with dielectric constant of 4.6. The designed VCO is operated at 3.2V, 10mA and has output value of 0.67dB. The VCO¡¯s phase noise property is -102dBc/Hz at offset frequence of 100kHz. The fabricated VCO is the same as target value and can be used for wireless subscriber network.
