摘 要: | 提出了一种基于模式匹配法的窄带Iris波导滤波器设计方法,通过引入Matlab优化使滤波器设计周期缩短了约1/3。设计的窄带滤波器相对带宽小于3%,且较好的克服了毫米波频段滤波器高频端带外抑制较差的难题。测试结果表明,该带通滤波器插入损耗小于0.8 dB,驻波比小于1.2,中心频率34.86 GHz,带外抑制52 dB@36.5 GHz,已被成功应用于某毫米波雷达通信系统中。

Design of a Narrow-band Iris Waveguide Filter Based on Mode-matching Method |
| |
Abstract: | A design method of narrow-band Iris waveguide filter based on Mode-matching is proposed, the design cycle of the filter is shortened a third by the help of Matlab optimization. The relative bandwidth of narrow-band filter is less than 3% .This filter overcomes the problem that high frequency out of band suppression is poor in the millimeter-wave band. The test results show that the filter of insertion loss is less than 0.8 dB, voltage standing-wave ratio (VSWR) is better than 1.2, center frequency is 34.86 GHz, the out-of-band rejection is 52 dB at 36.5 GHz and it has been successfully used in a millimeter wave radar communication system. |
