摘要
该文提出一种矩形和三角形结合的新型耦合环配合矩形耦合孔作为可调滤波器腔间耦合结构的耦合方式。分析了这种结构的耦合环平衡可调滤波器高低端带宽的机制,并且设计、制作了相应的同轴腔可调滤波器。实验结果表明该耦合环结构不仅能够平衡同轴腔可调滤波器的高低端带宽,而且可以提高可调滤波器的整机带宽指标和插入损耗。
In this paper,a novel coupling hoops of rectangle combine with triangle in coordination with coupling rectangle hole as inter-cavity coupling structure of tunable filter are brought forward.Analyze the reason why the structure of coupling hoops can balance the bandwidth in frequency range of a tunable filter.A corresponding coaxial tunable filter is designed and produced.The results of experiments indicate that the structure of coupling hoops not only can balance the bandwidth in frequency range of the coax...
