대역통과 필터의 롤오프 응답의 선명도는 무선 통신 시스템의 주요 관심사입니다. 감쇠극이 있는 대역통과 필터는 날카로운 롤오프를 제공합니다. 본 논문에서는 감쇠극 공진기(APR)를 갖춘 세라믹 콤라인 필터의 성능을 조사하고 감쇠극 공진기가 필터 응답에 미치는 영향을 연구합니다. 제시된 APR은 이전 APR의 개선된 버전이며 여기에 모델링되었습니다. 얻은 결과는 APR의 길이가 로딩 커패시턴스를 통해 소형화될 수 있음을 보여줍니다. 결과 부피는 약 400mm입니다.3이는 저지대역에서 동일한 감쇠율을 갖는 동축형 필터에 비해 매우 작습니다. 감쇠 폴 공진기를 추가하면 스커트 감쇠가 크게 향상됩니다. 저지대역에 감쇠 극이 있는 협대역 대역통과 필터가 설계되고 테스트되었습니다. 두 가지 설계 예는 필터 구성에서 감쇠 극 공진기의 유연성을 보여줍니다. 실험은 시뮬레이션 결과와 잘 일치함을 보여줍니다.

Abstract: The sharpness of the roll-off response of bandpass filters is a major concern for wireless communication systems. Bandpass filters with attenuation poles provide sharp roll-off. This paper investigates the performance of a ceramic comb-line filter with attenuation pole resonators (APRs), and studies the effects of the attenuation pole resonators on the filter response. The presented APRs are improved versions of previous ones and they are modeled here. The obtained results show that the length of APRs can be miniaturized via the loading capacitance. The resultant volume is about 400 mm3, which is very small comparing to coaxial type filters with the same attenuation rate in the stopband. With attenuation pole resonators added, skirt attenuation is greatly improved. Narrow bandwidth bandpass filters with attenuation poles in the stopband are designed and tested. Two designed examples demonstrate the flexibility of the attenuation pole resonator in the filter configuration. Experiments show good agreement with simulation results.
