A Hybrid Ring Coupled Varactor Reflection-type Analog Phase Shifter using an Inductor for Extending a Change in the Phase
위상확장용 인턱터를 사용한 하이브리드 링 결합 바랙터 반사형 아나로그 이상기
Abstract
An analog phase shifter is designed at the operating frequency 10GHz that is coupled with a hybrid ring and the network connecting an inductor series with a varactor to extend a continuous chage in the phase of the reflected output wave to be produced from a variation in the terminated varactor reactance as a variation in the reverse bias voltage. It is manufactured in a microstripline in consideration of an effect of the dispersion characteristics and discontinuities. As a resuls of an experiment, a change in the phase is achieved over 180 degree from
逆바이어스 電壓變化에 따라 終端된 바랙터 리액턴스 變化로부터 發生되는 反射波의 連續的인 位相變化를 擴張시키기 위하여 인덕터와 바랙터를 直列로 連結시킨 回路와 하이브리드 링이 結合된 아나로그 移相器를 動作周波數 10GHz에서 設計하였으며, 分散特性 및 不連續 影響을 考慮하여 마이크로 스트립線路로 製作하였다. 實驗結果, 逆바이어스電壓을 20V가지 變化시킴에 따라 位相은
