Title: Synthesis of Microwave Filters by Coupling Matrix Optimization
Keywords: Microwave filter, Chebyshev filter, Nelder-Mead
Abstract: This paper presents optimization method for synthesis of generalized microwave filters with arbitrary topology. The method utilizes Nelder-Mead local optimizer for coupling matrix determination. The synthesis procedure converges very fast as for a initial point is used a vector based on the Chebyshev all pole filter for the same degree of the filter. To validate the proposed synthesis method two numerical examples for resonant filters are computed. The frequency responses from the synthesis procedure and the theoretical responses show excellent agreement.
