Abstract

직육면체 형상의 세라믹 공진기의 내부에 분리형 입, 출력 공진기의 길이방향을 따라 한쌍의 입, 출력 공진홀을 형성하고, 상기 세라믹 공진기의 상면 및 양측벽에는 금속막을 형성한 유전체 필터에 있어서, 상기 세라믹 공진기의 개방단 입, 출력 공진홀 둘레에 입, 출력 금속전극을 형성하고, 상기 입, 출력 금속전극을 상향연장시켜 세라믹 공진기의 상면 일부에 입, 출력 접속단자를 형성하는 것으로, 유전체 필터의 공전저항값 증가에 따른 삽입손실 최소화 및 사이즈 축소와 PCB 장착이 용이하게 된다.A dielectric filter in which a pair of input and output resonance holes are formed in a rectangular parallelepiped ceramic resonator in a longitudinal direction of a separate input and output resonator, and metal films are formed on upper and side walls of the ceramic resonator. The input and output metal electrodes are formed around the open end input and output resonant holes of the terminal, and the input and output metal electrodes are extended upward to form input and output connection terminals on a part of the upper surface of the ceramic resonator. Minimizing insertion loss, size reduction, and PCB mounting are easy with increasing value.
