Abstract

An ultra-wideband and narrow-band bandpass frequency quintplexer is presented in this paper. The quintplexer was fabricated in microstrip technology, which consists of a long distributed coupling feeding line, an ultra-wideband bandpass channel filter and four narrow-band bandpass channel filters. The ultra-wideband bandpass filter was developed with an extended upper stopband to accommodate the other four narrow-band bandpass channels. To validate the design concept, the quintplexer was designed, fabricated, and tested, where simulation results agree well with measurement results. The center frequencies and fractional bandwidths for each channels are 0.7 GHz (100%), 1.5 GHz (10.6%), 2.0 GHz (7%), 2.5 GHz (6.5%), and 3.0 GHz (6.7%).
