Abstract

본 발명 유전체 필터는 일측 단부면으로부터 타측으로 연장된 통공과 하측면에서 인접한 통공사이에 배열된 요구를 갖는 유전체 블럭으로 구성되고, 상기 유전체 필터의 상측면이 편면상으로 요구가 없어 유료흡인영역이 넓은 흡인패드에 의하여 유전체 블럭이 효과적으로 인상되고 이동되어 쉽게 인쇄회로기판에 취부될 수 있다.

Description

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제4도는 본 발명에 따른 유전체 필터의 실시형태를 보인 사시도.

Claims (2)

  1. 내주면에 내부전도체가 배열된 다수의 통공, 측면의 외부전도체, 일측면의 입력/출력단자와, 단간결합도를 조절하기 위하여 두 인접한 통공사이에서 하측면에 배열된 평행한 요구를 갖는 유전체 블럭으로 구성되고, 상기 유전체 블럭이 그 입력/출력단자가 입력/출력회로에 연결되게 이들 회로가 형성된 인쇄회로기판상에 고정되는 유전체 필터에 있어서, 입력/출력단자가 형성된 하측면에 대향된 상기 유전제 블럭의 상측면에 평면형으로 단간 결합도 조절용 요구가 없음을 특징으로 하는 유전체 필터.
  2. 청구범위 1항에 있어서, 유전체 블럭의 하측면에 배열된 단간결합도 조절용의 각 요구가 유전체 블력의 높이에 대하여 4/5 이하의 깊이를 가짐을 특징으로 하는 유전체 필터.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
