Abstract
A device for distributing and combining microwave electric power which is used, for example, in a high power microwave amplifier and combines or distributes microwave electric power between a first microwave path such as a standard waveguide and a plurality of second microwave paths such as a plurality of waveguides or MIC transmission lines. The device comprises a horn whose throat portion is coupled to the first microwave path, a oversized waveguide coupled to the opening portion of the horn at one end and coupled to the plurality of the second microwave paths, and, for example, a dielectric lens, or one or more reflectors, for uniformalizing the phases of the microwave signals distributed by the horn or for adjusting the phases of the microwave signals output from the second microwave paths.
