Abstract: The inventive microwave filter is based upon the utilization of a prototype filter of known type, and a recognition of the properties of microwave C-sections, and parallel coupled line capacitance arrays. A prior art filter is chosen as a prototype filter and is partitioned into a general equivalent circuit derived by applying electrical constraints to the standard equivalent circuits for microwave C-sections and parallel coupled line capacitance arrays. A set of general equations is then written for the equivalent circuit, and by using the equations it is possible to design filters having a wide range of desired filter characteristics simply by substituting the values from the prototype filter into the equations. It is therefore possible to construct a wide variety of filters from a few standard parts. Strip line filters can also be made utilizing the general equations.
