摘要

提出了一种具有远杂散阻带的带阻滤波器。首先提出了一种具有远杂散阻带的同轴腔。然后将几个这样的同轴腔串联起来，形成一个带阻滤波器。为了说明设计过程，设计了一个同轴带阻滤波器，其中心阻带为5 GHz，带宽为2 GHz，其第一个杂散阻带高于18 GHz。制作并测试了样品过滤器。试验结果与模拟结果吻合较好。带阻滤波器的参数由标准滤波器的参数明确推导而来，并假定标准滤波器为参考。仿真和实测结果都证明了这一点。

A Band-Stop Filter with Far Spurious Stop Bands

This paper presents a band-stop filters with far spurious stop bands. At first, a coaxial cavity with far spurious stop band is proposed. Then several such coaxial cavities are connected in series to form a band-stop filter. To illustrate the design process, a coaxial band-stop filter has been designed, with a stop-band centered at 5 GHz, a bandwidth of 2 GHz, and its first spurious stop-band higher than 18 GHz. The sample filter has been fabricated and tested. Tested results show good agreement with simulated results. The parameters of the band-stop filter are explicitly derived from those of a standard filter, which is assumed as a reference. It has been proved in both the simulation and the measurement.
