摘要
本文介绍了一种新型电容与电感加载相结合的腔体滤波器。利用对这种加载方式设计出了一款X波段六腔滤波器,其长度比普通直接耦合腔滤波器减少40%-50%,并且结构简单、加工容易,带内插损小,通过测试其插损小于0.55dB,带内反射小于-20的dB。
This paper introduces a capacitive and inductance loaded waveguide band-pass filter.An order-6 X-band waveguide filter is designed.Simulations show that the length can be reduced by 40% and 50% respectively,compared with a conventional directly-coupled waveguide filter,The tested results confirmed from 8.0GHz to 13GHz,the insertion loss is lower than 0.55dB and reflection lower than -20dB.
