Design of a novel microstrip multiplexer with extendable channel
摘要
Abstract
A novel microstrip multiplexer with arbitrary number of channels and small size was proposed,which overcome the conventional multiplexer's disadvantage of not being able to combine too many channels.The multiplexer consisted of a common input feeder and multiple bandpass filters.Bandpass filters were combined together by coupling with the input feeder.The interaction between channel filters could be compensated by adjusting the parameters of the channel filters.Therefore,no additional compensation circuit was needed for the proposed multiplexer,which led to a lower volume or smaller size than conventional multiplexers.In addition,the length of the input feeder was extensible,making it feasible to design a multiplexer consisting of arbitrary number of channels.With the novel structure,the improved synthesis approach and the improved space mapping technique,a six-channel microstrip multiplexer was designed and fabricated.Its center frequency is 3.97 GHz.And its each channel is a three-order Chebyshev bandpass filter with a bandwidth of 80 MHz.The guard band is 100 MHz.Measurement results show that the return loss is about 14 dB and the insertion loss is about 3.6 dB.The experimental results verify the validity of the proposed method.关键词
