ABSTRACT:
There is disclosed a method for designing an electrical filter comprising the steps of: a) selecting at least one determined function called seed function; b) determining the product of all these seed functions to define a transfer function generating function of the electrical filter; c) translating the electrical filter transfer function into transmission zeroes and poles; d) and synthesizing those electrical filter dimensions that achieve the required zeroes and poles. A particular application is aimed at a Chebycheff filter comprised of serially arranged resonant cavities and couplers, operating in the microwave range.
