一种电控可调双工器的研究与设计
The Study and Design of an Active Switch Tunable Duplexer
摘要
Abstract
Aiming at the high-reliability and high-selectivity requirement for RF front-end duplexer,based on the composition principle of duplexer,the solving schemes are brought forward to active switch duplexer.Commercial relay switches are used to select the working frequency.The duplexer is composed of the circulator and the filters,thus seamless coverage is achieved in the whole frequency band.Fixed filters are designed by the coupled bandwidth in order to use a set of data for all filter implementation,with the advantages of high-reliability and modularization.In the end,an example is given,with good application effect.关键词
