%C Montreal, QC %A S. Khalid %A W.P. Wen %A L.Y. Cheong %T Synthesis and design of four pole ultra-wide band (UWB) bandpass filter (BPF) employing multi-mode resonators (MMR) %X A complete synthesis and design of fourth order UWB BPF has been presented in this paper. Based on MMR, equivalent circuit is used to derive transfer function which is then used to extract the filtering function. For optimal solution, mathematical formulation is used to calculate characteristic impedance of filter in order to have chebyshev type frequency response. To validate the synthesis a prototype is designed and fabricated. Experimental results show good agreement with proposed synthesis. © 2012 IEEE. %K Characteristic impedance; Chebyshev; Filtering functions; Fourth order; Mathematical formulation; Multimode resonators; Optimal solutions, Frequency response; Ultra-wideband (UWB), Bandpass filters %R 10.1109/MWSYM.2012.6257764 %D 2012 %L scholars2875 %J IEEE MTT-S International Microwave Symposium Digest %O cited By 7; Conference of 2012 IEEE MTT-S International Microwave Symposium, IMS 2012 ; Conference Date: 17 June 2012 Through 22 June 2012; Conference Code:92871
