具有两个传输零点的高温陶瓷梳型带状线滤波器
High temperature ceramic comb-stripline bandpass filter with two transmission zeros
摘要
Abstract
In this paper,a novel high temperature ceramic comb-stripline bandpass filter (BPF) with two transmission zeros is proposed.The novelty of this design lies in constructing a rectangular metalized hollow instead of the traditional rectangular-bar stripline structure.Its unloaded quality factor can be effectively improved by increasing the thickness of the quarter-wavelength resonator using the proposed structure,resulting in a reduced insertion loss.Investigation shows that rectangular metalized hollow filter owns lower insertion loss than the traditional stripline filters.Two transmission zeros in the upper stopband are produced to improve stopband rejection and passband selectivity.For demonstration,a second-order BPF is designed.Good agreement can be obtained between simulated and measured results,showcasing the advantages of low loss and compact size.关键词
