A Study on $90^{\cire}$ Constant Phase Shifter

전송선형 $90^{\cire}$ 정위상기에 관한 연구

This paper presents the realization method of 90$^{\circ}$ constant phase shifter in the VHF band, constructed by the entirely differens idea from the conventional method of the realization of constant phase shifter in the audio frequency range. The construction of 90$^{\circ}$ constant phase shifter is. simple and can be easily realized by using the distributed constant element, transmission line, and the lumped constant elements, R,C,L.

본논문은 현재 AF주파수변역에서 90° 정위상기를 실현하고 있는 방법과는 전혀 다른 착상으로 VHF 고파수대에서 90° 정위상기를 실현하는 새로운 방법을 제시하였다. 이 90° 정위상기의 구조는 간단하며 분포정수소자인 전송선과 집중정수소자인 R.L.C로 용이하게 실현된다.
