摘要：

针对Ka频段卫星通信系统中对阻收滤波器的工程应用需求,提出一种低损耗波导高通滤波器的设计方法。利用波导低频截止特性及阶梯阻抗变换法,在软件中进行建模仿真优化后,通过参数扫描得到一个合理的设计方案。实物测试结果表明通带25～28 GHz插入损耗＜0.4 dB;阻带22～23 GHz抑制＞40 dB,是一款可应用于实际工程的高性能滤波器。

Abstract:

This paper presents a method of designing low loss waveguide filter for Ka band satellite communication system.After constructing simulation models based on the theory of cut-off waveguide and step impedance conversion,we get a proper result by optimization and variable sweeping in the software.The test results shows that is a high performance filter can be applied to practical engineering,the insertion loss is less than 0.4 dB in pass band (25~28 GHz),and greater than 40 dB in stop band (22~23 GHz).

Key words: Ka band;step impedance conversion;variable sweep;high pass filter
