一种大功率超宽带螺旋双工器设计

摘要

设计并实现了一种超宽带（Extra －Wideband，EWB）螺旋双工器，通过它能把多信道邻接型收、发信机组合起来，实现了多通道通带邻接频段的无缝全覆盖。符合目前“低插损、小型化、通带比邻”的收发信机拓扑结构设计新理念，为应对目前频谱资源持续紧张问题提供了一种新的解决方案，设计实例进一步验证了该方法的可行性与实用性。%This paper presents and realizes an extra -wideband helical duplexer which is able to combine multi-channel adjacent transmitters and receivers and achieves full cover of multi -channel pass -band adjacent frequency band.It caters to new ideas of the design of connecting structure for transmitters and receivers featu-ring low insertion loss,small -sized,and adjacent pass -band.This paper provides a new solution for insuffi-cient frequency spectrum resources.The feasibility and practicability of this method are verified by the de-signed examples as well.
