ABSTRACT:
A radio frequency power divider/combiner having a pair of conductive plates between which the dominant E-type mode is produced by symmetrical excitation at a central point preferably by means of a coaxial line having its outer conductor attached to the first of these plates, and its inner (center) conductor passing freely therethrough and attaching to the second of these parallel plates in an impedance matching flareout. A plurality of uniformly distributed collectors each in the form of a loop feeding the coaxial branch port provides for low loss. The entire assembly is in the form of a thick disc with radially extended branch ports about its perimeter and a common excitation feed extending normally from the surface of the first plate. Resistors are provided between adjacent portions of the end-on loops for the suppression of circumferential current components corresponding to undesired modes.
