Abstract(in English) | We investigate the design method for a duplexer consisting of bandpass filters(BPFs) using various half-wavelength resonators. The duplexer is designed based on the general filter theory with narrow band approximation and tap-coupling technique. We use lumped-element loaded resonators such as capacitor( C)-loaded type, inductor(L)-loaded type and LC-loaded type for filter structure. The results of this study lead us to the conclusion that the design of the proposed duplexers is of use for realizing high performance characteristics without increasing the number of elements. |
