Abstract
고주파 전력 결합기가 개시된다. 2-way 방식의 고주파 전력 결합기는 고주파 신호가 입력되는 제1 입력단 및 제2 입력단; 제1 입력단 및 제2 입력단을 통해 입력된 고주파 신호들이 동일한 위상을 가지는 경우, 상기 고주파 신호들 간의 합 신호가 출력되는 제1 출력단; 및 제1 입력단 및 제2 입력단을 통해 입력된 고주파 신호들이 서로 다른 위상을 가지는 경우, 상기 고주파 신호들 간의 차 신호가 출력되는 제2 출력단을 포함하고, 상기 제1 입력단, 제2 입력단, 제1 출력단, 제2 출력단은, 공기층 사이에 배치된 유전체층에 위치한 도체 선로를 포함하는 서스펜디드 선로(Suspended Line) 전송 선로로 연결되며, 상기 서스펜디드 선로는, 마이크로스트립(Microstrip) 전송 선로와 연결되는 구간의 상기 도체 선로에서 광대역 천이로 연결될 수 있다. 고주파 신호들 간의 차 신호가 출력되는 제2 출력단은 반원 형태의 고주파 종단기로 연결될 수 있다.
