임피던스 인버터와 고조파 발진기를 이용한 VCO 설계 및 제작
Design and Implementation of a VCO Employing Harmonic Oscillators and a Impedance Inverter
Abstract
In this paper, improved VCO(voltage controlled oscillator) with push-push structure and high impedance-inverter is designed and implemented. Two harmonic oscillators are combined into push-push structure. As a result, the fundamental suppression and the output power have been progressed. For the improved coupling characteristics between hair-pin resonator and two parallel microstrip line using high impedance inverter, the phase noise has been suppressed.
