Abstract

본 발명은 입출력단자, 로딩 및 커플링 캐패시터가 구현된 유전체기판을 세라믹 유전체블럭에 부착 생성하여 가격을 절감시키고 소형화를 꾀한 유전체 필터에 관한 것이다.The present invention relates to a dielectric filter for reducing the cost and miniaturization by attaching and generating a dielectric substrate on which an input / output terminal, a loading capacitor, and a coupling capacitor are implemented.

본 발명은 일측에 형성된 접지패턴(21)과, 중앙에 스로우홀(22a)(23a)(24a) 이 천공된 3개의 전극패턴(22,23,24)과, 양측에 형성되는 입력패턴(25) 및 출력패턴(26)과, 배면에 스로우홀(22a)(23a)(24a)을 중심으로 형성된 솔더링부(27,28,29)로 구성된 유전체기판(20): 및 사각형성의 세라믹 재질의 몸체(34)와, 상기 유전체기판(20)의 스로우홀(22a~24a)과 일치되도록 상기 몸체(34)에 형성된 홀(31~33)로 구성된 유전체블럭(35);을 포함하여 된 것이다.The present invention provides a ground pattern 21 formed at one side, three electrode patterns 22, 23, 24 having perforated through holes 22a, 23a, and 24a at the center, and input patterns 25 formed at both sides. ) And an output pattern 26, and a dielectric substrate 20 composed of soldering portions 27, 28, and 29 formed on the back of the through holes 22a, 23a, and 24a. And a dielectric block 35 formed of a body 34 and holes 31 to 33 formed in the body 34 to coincide with the throw holes 22a to 24a of the dielectric substrate 20.

따라서, 본 발명은 2개 이상의 공진기를 사용하여 구현하는 고주파 유전체 필터를 유전체기판과 유전체블럭만으로 구현하게 됨으로서, 소형화 및 저가의 유전체필터를 구현할 수 있는 효과가 있다.Therefore, the present invention implements a high frequency dielectric filter using only two or more resonators using only a dielectric substrate and a dielectric block, thereby achieving a miniaturized and inexpensive dielectric filter.
