Abstract: With the rapid development of microwave communication technology, the high performance microwave filters have played important roles in the microwave and wireless communication system. A synthesis procedure, using optimization, for multiple coupled resonators filters having general topology and general response was described. The cost function for the optimization was based on the values of the characteristic function at its zeros and poles. The procedure deduced the coupling matrix of filters by using gradient-based Optimization technique, and also researched the relationship between filter parameters and physical structure. A high performance six cavities band-pass filter worked in 2.3GHz which was designed by this way had the response coincided with the theory response. The example is reported which validates the proposed synthesis procedure.
