Abstract:

This paper illustrates a method for the synthesis of microwave multiplexer with characteristic polynomial.Using iterative algorithm,the characteristic polynomial of multiplexer and arm filter can be optimized in a law-pass frequency domain.By this method,the coupling coefficient can be calculated for each branch.With the impact of the remaining branches of the multiplexer in consideration,the filter optimization time is shorter than before.The transmission zeros of each branch filter can be given any value.The method is also applicable to the synthesis of duplexer and multiplexer.Finally,using software Ansoft Designer,a multiplexer is designed.The simulation curve is consistent with the expected one.
