Book Description: Focusing on generalized filter design by computer optimization, this text shows how to employ sophisticated, optimization-based approaches to filter design. It provides ready-made CAD filtre design algorithms aimed to help in the development of a wide variety of filter configurations. The book presents: proven optimization oriented techniques for designing filter structures that have equal ripple insertion or return loss in the passband; an effective filter design procedure based on equal ripple optimization; details on designing lumped element, E-plane, ridged waveguide and coplanar waveguide filters; and a numerically efficient method for calculating the insertion and return losses of a cascade of lossless symmetrical two-ports. Over 200 equations and dozens of real-world examples are included.
