Abstract

This paper describes an unequal Bagley divider using uniform transmission lines with adjustment electrical lengths between output ports. To obtain an arbitrary dividing ratio of Bagley divider, we have only adjusted the electrical lengths of the transmission line between output ports. All the transmission lines have the same characteristic impedance value. This design method does not require an impedance transformer for port matching. For verification, we simulated and fabricated a 3-way, 1:2:1 and 5-way, 2:3:4:3:2 ratio Bagley divider with an operating frequency of 2 GHz. The experimental results are in agreement with the simulated results.

본 논문은 균일한 임피던스를 갖는 출력 포트사이 전송선로의 전기적 길이를 다르게 함으로서 비대칭 Bagley 분배기 설계에 대한 내용을 서술하였다. 이 분배기는 입력 포트와 연결된 출력 포트의 전기적 길이만을 조정하여 출력 포트에 원하는 임의의 출력 비율을 얻을 수 있고, 모든 전송선로의 특성 임피던스는 균일한 것이 특징이다. 이러한 설계 방법을 사용하면 비대칭 출력을 얻을 수 있음에도 출력포트에는 임피던스 변환기를 사용하지 않는다. 이것을 증명하기 위해서 동작주파수 2 GHz에서 1:2:1 비율의 3차와 2:3:4:3:2 비율의 5차 비대칭 Bagley 분배기를 시뮬레이션과 제작하였다. 측정 결과는 시뮬레이션과 동일함을 확인하였다.
