Abstract
Abstract The power divider/combiner includes an impedance transformer arrangement coaxial of and within an outer conductor, an input/output coaxial transmission line coupled to the transformer arrangement and the outer conductor and first N-discrete, spaced transmission lines supported by a dielectric cylinder disposed coaxial of and within the outer conductor, each of the first transmission lines being coupled to the transformer means, where N is an integer greater than one. Second N-discrete, spaced transmission lines are disposed coaxial of and transverse to the outer conductor remote from the transformer arrangement, each of the second transmission lines being coupled to a different one of the first transmission lines and terminating in a common metallic disc coaxial of and adjacent the axis of the outer conductor. N-output/input ports are each coupled to a different one of the first transmission lines adjacent the transformer arrangement and N-load ports are each coupled to a different one of the first transmission lines adjacent the second transmission lines.
