Abstract

The phase locked oscillator having a low phase noise and high output in Ku-band was designed. To obtain the low phase noise and high output characteristics of oscillator, the nonlinear equivalent circuits of p-HEMT was analyzed by TOM method and we have decided the trade-off bias point between the low phase noise and the output power of oscillator. The designed phase locked oscillator with prescaler for stable operation, experiment results exhibits output power of 1003m with phase noise in the phase locked state of -824BC/HB at 10mz offset from 13.250Hz, and simulation result of 1003m output power in the phase noise -840Bc/Hz at 10KHz offset frequency respectively. a good agreement has been obtained between simulations and experiments results.

본 논문에서는 저 위상잡음과 고출력 특성을 나타내는 Ku-대역 위상동기발진기를 설계하였다. 발진기소자의 비 선형 파라메터를 분석하여 위상잡음과 발진기출력에 영향을 주는 파라메터의 관계를 최적화시켜 저 위상잡음과 고 출력 특성을 절충되는 바이어스를 구하였다. 위상동기 발진기의 고 안정 특성을 위하여 전치분주형으로 설계하였으며 실험한 결과 위상동기된 상태에서 발진기출력은 10.17dBm이었으며 위상잡음은 13.25GHz에서 10KHz 떨어진 주파수에서 -82d3c/Hz을 보여 10dBm의 출력과 -84dBc/Hz@10KHz에 매우 근접함을 알 수 있었다.
