Abstract

This paper deals with a millimeter wave source which is utilizing sub-harmonic injection-synchronization technique. A 8.7GHz oscillator with MES-FET is fabricated, and is driven as a harmonic output oscillator at 17.4GHz by means of sub-harmonic injection-synchronization. The oscillator operates as a multiplier as well as oscillator in this system. Adopting this technique, we can obtain a high stable, high frequency millimeter wave source even though self-oscillating frequency of an oscillator is relatively low. In the experiments, the range of injection-synchronization is about 26MHz and is proportional to the input sub-harmonic power. From the spectrum analysis of the 2nd harmonic output. we blow that the phase noise of the harmonic oscillator is remarkably decreased.

서브하모닉파 주입동기에 의한 밀리미터파 대역 고주파원의 고성능화에 대하여 다루었다. MES-FET로 8.7GHz의 발진기를 구성하고 서브하모닉파의 주입동기 방식으로 구동하여 17.4GHz의 고조파를 발생시켰다. 이러한 시스템에서 발진기는 발진과 동시에 체배기의 기능을 수행하여 안정된 고조파 발생시킬 수 있다. 이 기술을 채택하면 자려발진주파수가 비교적 낮은 발진기로도 고안정, 고출력 고주파를 발생시키는 고조파출력 발진기를 실현할 수 있다. 실험의 결과, 주입 동기의 범위 26MHz 내에서 고출력 고조파가 관측되었으며, 서브하모닉파 주입전력에 비례하였다. 스펙트럼 분석기로 고조파 출력의 파형을 관측한 결과, 제2고조파 출력의 위상 안정성이 현저히 향상되었음이 확인되었다.
