Abstract :
A synthesis procedure, using an improved analytical gradient-based optimization technique, for cross-coupled resonator bandpass filters with given response and given topology is described. Weights are introduced in the cost function in order to generate transmission zeros more easily and improve the convergence of the optimization technique. Examples of the design of fifth-order filters with symmetric or asymmetric response are presented.
