Design and synthesis of microwave filters.

Design and synthesis of microwave filters presented in this paper consist of three classes of filters. They are the short circuit stubs bandpass filter based on the conventional Chebyshev rational function, the lowpass filter and combline bandpass filter are based on the Generalized Chebyshev rational function. The design technique for the short circuit stub filter is based on an approximate design method, using close form equations, whereas for the lowpass filters and the combline bandpass filters, they are based on an exact synthesis technique, which involves the solving for roots, forming Hurwitz polynomial and element extraction. All the design and synthesis procedure were implemented using Mathcad version 8.
