초록

본 논문은 단락 또는 단선 스터브가 연결된 전송선로를 이용하여 높은 분배 비율을 갖는 비대칭 전력 분배기를 구현하는 방법을 제안하였다. 제안된 방법은 2포트 전송선로 중앙에 임의의 임피던스로 변환할 수 있도록 별도의 포트를 추가한 3포트 전송선로와 단선 또는 단락 스터브가 각 포트에 병렬로 연결된 3포트 전송선로를 등가회로로 보고 회로를 해석한 것이다. 이러한 방법의 타당성을 증명하기 위해서, 분배 비율 k2 = 20 dB를 갖는 윌킨슨 전력분배기와 k2 = 17 dB를 갖는 Gysel 전력분배기를 3포트 전송선로 등가회로를 이용하여 중심주파수 1 GHz에서 설계하였으며, 전기적 특성의 실험 결과는 시뮬레이션과 잘 일치함을 확인하였다.

This paper proposes a method of implementing an unequal power divider for high splitting ratios by using transmission lines connected with open and short stubs. The proposed method is an equivalent circuit analysis of a transmission line with an additional port so that it can be converted to an arbitrary impedance in the center of a 2-port transmission line and a 3-port transmission line with an open or short stub connected in parallel to each port. To prove the validity of this method, a Wilkinson power divider with k2 = 20 dB splitting ratio and a Gysel power divider with k2 = 17 dB splitting ratio were designed at a center frequency of 1 GHz using a 3-port transmission line equivalent circuit. The experimental results of the electrical characteristics are in good agreement with the simulation.
