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 형성하고, 상기 입, 출력 금속전극에는 입, 출력공진기를 결합시키기 위한 결합 커패시턴스를 발생하는 빗살형 입, 출력 커플링 전극을 각각 전기적으로 접속시켜 형성하는 것으로 유전체 필터의 공진저항값 증가에 따른 삽입손실 최소와, 사이즈 축소, PCB 장착 용이화 및 기계적 강도의 증가 효과를 얻을 수 있게 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. An input and an output metal electrode are formed around the open end and output resonance holes of the open end, and the input and output metal electrodes are extended upward to form input and output connection terminals on a portion of the upper surface of the ceramic resonator. Is formed by electrically connecting the comb-shaped input and output coupling electrodes that generate coupling capacitances for coupling the input and output resonators. The effect of facilitating and increasing the mechanical strength can be obtained.
