세라믹 필터를 제조함에 있어서, 분극 방향이 압전기판의 주평면과 평행하게 되는 상태에서 분극방향과 평행한 진동부 특면의 무전극부를 제거시킨 다음, 상기 진동부에 있는 전극의 폭과 음차형으로 만들어진 압전기판의 폭을 서로 동일하게 형성시켜, 그 전면부에는 2중 모드형 전극을 음차형 압전기판에 서로 대칭으로 설치시키는 한편 그 이면주에는 전면부와 동일한 폭으로 접지용 전극단자를 설치시켜서 됨을 특징으로 하는 2중 모드형 세라믹 필터의 제조방법.In manufacturing the ceramic filter, the electrodeless part of the vibrating part surface parallel to the polarization direction is removed in a state where the polarization direction is parallel to the main plane of the piezoelectric plate, and then the width and the tuning fork of the electrode in the vibration part are made. The width of the piezoelectric plate is formed to be equal to each other, and the dual mode electrode is symmetrically installed on the tuning-fork piezoelectric plate on the front part thereof, and the grounding electrode terminal is provided on the back side of the same width as the front part. A method of manufacturing a dual mode ceramic filter, characterized in that. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
