Abstract

This paper presents the analysis and the design methods of the crossover junctions including the output phase. The general solutions were derived analytically through an even-odd analysis of the reflection coefficients and the impedance parameters for the crossover junction with arbitrary output phase. The general solutions were applied to a real crossover junction structure to derive the exact design formula for the arbitrary output phase. The results agreed well with the existing studies. The designed circuit satisfied the crossover junction operation with the exact output phase.

본 논문에서는 크로스오버 접합에서 출력 위상을 고려한 회로해석 및 설계 방법을 제시한다. 먼저 even-odd 분석을 통해 임의의 위상을 가지는 크로스오버 접합이 만족시켜야 할 반사계수 및 임피던스 파라미터에 대한 일반해를 해석적으로 유도하였다. 또한 주어진 일반해를 실제적인 크로스오버 접합회로 구조에 적용하여 임의의 츨력 위상값을 가지는 크로스오버 접합의 정확한 설계 공식을 도출하였으며 그 결과가 기존의 연구에서 제시된 결과와 부합함을 확인하였다. 이를 이용하여 설계된 회로가 설계목표와 일치하는 정확한 출력 위상을 가지는 크로스오버 접합으로서의 성능을 만족하는 것을 입증하였다.
