Abstract:

In recent years, a great deal of effort has been made on computer-aided design and tuning for microwave filters. However, there is little literature on the triplexer. The rational model of the triplexer is the key condition for computer-aided design and tuning. A new method based on the improved Cauchy method to extract the rational model of the triplexer is presented in this paper. A triplexer's rational model is extracted by the new method. The extracted rational model response agrees with the simulated response well, which shows the validity of the new method well.

Key words: computer-aided design, Cauchy method, triplexer, rational model
