ABSTRACT:
A microwave radial power divider/combiner device having desirably broad bandwidth response over a selected frequency range. The device includes a radial waveguide that has a number of adjoining annular sections, each of selected radial length and axial height, to provide lumped circuit parameters closely euqivalent to those of an ideal filter with the desired passband characteristics. The ideal filter is first designed using conventional synthesis techniques, then modified, if necessary, to allow its realization in radial waveguide form. The waveguide sections are selected to have lengths and uniform heights to approximate the lumped circuit parameters of the filter, and the dimensions are then optimized to provide the closest approach to the desired performance characteristics.
