Hello,
I have designed a composite band pass filter, BPF (LPF+HPF) using short and open stubs. I need to do mathematical analysis for this design using even/odd analysis and also ABCD parameters ...Can someone help me in this or refer a paper which has already done such analysis for similar kind of design.
Thanking in advance!!!
Best Regards

Odd-even mode analysis is a powerful tool for the analysis of composite bandpass filters. The basic idea behind odd-even mode analysis is to decompose the filter into two separate filters, one for the odd modes and one for the even modes. The odd mode filter consists of all the resonators that are excited by odd-mode signals, while the even mode filter consists of all the resonators that are excited by even-mode signals.
Once the filter has been decomposed into odd and even mode filters, the two filters can be analyzed independently. The odd mode filter is typically analyzed using a transmission line model, while the even mode filter is typically analyzed using a coupled resonator model.
Odd-even mode analysis has several advantages over traditional analysis methods. First, it is a very intuitive method that can be easily understood by engineers. Second, it is a very powerful method that can be used to analyze a wide variety of composite bandpass filters. Third, it is a very versatile method that can be used to design filters with a wide variety of specifications.
Here are some of the key steps in odd-even mode analysis:
Dear Prof. Murtadha,
Thank you so much for your kind reply and guidance. I got some idea about it but since i am completely new to it, i will be thankful, if you can suggest some specific even/odd mathematical analysis as per my design of composite BPF using stubs. also if possible some light on ABCD or coupling matrix analysis....Thanking you in advance!
Best Regards
