提高级联滤波模块带外抑制的方法
Method of improving out-band rejection of cascaded filter module
摘要
Abstract
Cascade filter plays an important role in short-wave communication. To improve out-band rejection, through studying the relationship between the out-band rejection and the reflection coefficient, the mismatch loss formula of cascaded network is proposed. The means of using attenuation network and isolator to improve the out-band rejection are analyzed. The possibility of inserting a general network to improve the out-band rejection is proposed, and the method is proved to be efficient and feasible.关键词
