Abstract

In this paper, we derived the design equation and implemented the unequal Gysel power divider that is one external resistors using the ABCD parameters analysis. Conventional unequal Gysel divider is difficult to obtain the characteristics of isolation and return loss at between output ports because it can't select a theoretical value of external resistor. To solve those problems, we design the new unequal Gysel power divider with transmission lines and one external resistor that has the characteristics of conventional unequal Gysel divider. To validate this design method, we simulated and measured an 4: 1 unequal Gysel power divider at the center frequency 1 GHz. The measured performances agreed well with the simulation results.

본 논문은 비균등 Gysel 전력 분배기에서 사용되는 두 개의 외부저항을 ABCD 파라미터 해석을 통하여 한 개의 저항으로 변환하는 식을 유도하고, 구현한 내용이다. 기존의 비균등 Gysel 전력 분배기는 두 개의 외부 저항을 이론적인 값으로 구현하기 어렵기 때문에 출력포트 사이의 격리도 및 반사 손실을 얻기가 어렵다. 이러한 문제를 해결하기 위해서 새롭게 설계한 비균등 Gysel 전력분배기는 전송선로와 한 개의 저항을 사용하여 기존 전력 분배기와 동일한 전기적 특성을 얻었다. 이러한 설계방법의 타당성을 보기위해 중심 주파수 1 GHz에서 4:1 비균등 Gysel 전력분배기를 제작하였고, 이것의 특성이 시뮬레이션과 동일함을 확인하였다.
