Abstract :
A D-band push-push voltage-controlled oscillator (VCO) with a constant output power is presented in this paper. A tunable quarter-wave (λ/4) line is proposed to minimize the output power degradation by the mismatch between λ/4 line and the output frequency. The proposed VCO has an oscillation frequency of 120 GHz and a power consumption of 11.0 mW at a supply voltage e of 1.2 V. And it has a minimum output power of -26.0 dBm and the maximum deviation of output power of 1.6 dBm when the tuning range is changed from 115.8 GHz to 126.8 GHz.
