Abstract

본 발명은 마이크로 스트립 평행결합선 방식의 고온초전도 6-극 대역통과 필터에 관한 것으로서, 마이크로파 특성이 우수한 단결정 기관과, 상기 단결정기판 상부의 일측에 형성된 신호 전송용 입력단과, 상기 단결정기판 상부의 상기 신호 전송용 입력단의 타측에 형성된 출력단과, 상기 단결정기판 상부에 입력단과 출력단과 연결되도록 형성된 ㄱ자형의 정합망과, 상기 다결정기판 상부의 정합망 사이에 갯수에 의해 극수를 결정하는 6개의 마이크로 스트립이 평행결합선 방식으로 형성된 필터 패턴과, 상기 다결정기판 하부에 형성된 접지판을 포함한다. 따라서, 손실 특성을 저하시키지 않으면서 스커트 특성을 향상시킬 수 있다.The present invention relates to a high-temperature superconducting 6-pole bandpass filter of a microstrip parallel coupling line method, comprising: a single crystal engine having excellent microwave characteristics, an input terminal for signal transmission formed on one side of the single crystal substrate, and the signal on the single crystal substrate. There are six microstrips that determine the number of poles by the number between an output terminal formed on the other side of the transmission input terminal, an L-shaped matching network formed to be connected to an input terminal and an output terminal on the single crystal substrate, and a matching network on the upper portion of the polycrystalline substrate. It includes a filter pattern formed in a parallel coupling line method, and a ground plate formed under the polycrystalline substrate. Therefore, the skirt characteristic can be improved without lowering the loss characteristic.
