An efficient design procedure for HTS coupled microstrip resonator filters is presented in this paper. Based on the relationship between the coupling matrix M and the frequency response of a filter, we made a program to get a response from a known M matrix and to achieve a better result by optimization of the M matrix. Using its optimization recursively, we can easily find the optimal filter configuration with a desired filter performance. A design example is given to demonstrate its feasibility. This computer-aided design method is very useful for HTS filter design and tuning.
