Abstract

This paper presents a high dividing ratio unequal dualband divider using coplanar waveguide (CPW) and shunt connected open stub transmission lines. In order to implement transmission lines for a dualband divider using design equations, the low impedance lines of divider can be realized a shunt connected open stub transmission line. Also, the high impedance lines are realized by CPW transmission lines. To certify the validity of an unequal dualband divider using CPW and shunt connected open stub transmission lines, the 10:1 unequal dualband divider is implemented at operating frequency of 1 and 2 GHz. Good experimental performance at each frequency are obtained, which are in good agreement with the simulated results.

본 논문은 CPW와 개방 스터브가 병렬 연결된 전송선로를 사용하여 높은 분배 비율의 비대칭 이중대역 분배기를 나타내었다. 이중대역 설계 방정식에 의하여 계산된 전송선로의 구현은 낮은 임피던스의 전송선로는 짧은 선로와 병렬로 개방 스터브가 주기적으로 연결된 형태로 그리고, 높은 임피던스 전송선로는 CPW 선로 형태로 구현하였다. 이러한 두 종류 전송선로를 이용한 이중대역 분배기의 설계방법의 타당성을 확인하기 위해서 중심 주파수가 1 GHz와 2 GHz인 10:1 비대칭 이중대역 전력분배기를 제작하였고, 이것의 측정 결과 특성이 시뮬레이션과 동일함을 확인하였다.
