Abstract
Apparatus is disclosed in which a ring of microwave amplifiers are spaced around the top of a cavity closure structure containing upper and lower splitter and combiner cavities. The inputs and outputs of the amplifiers are connected by, respectively, input and output coaxial couplers to points in, respectively, the splitter and combiner cavities which are spaced radially outward of, and equiangularly around the centers of these cavities. In operation, input microwaves are distributed by the splitter cavity and input couplers to the amplifiers to be amplified by them in parallel, and the several microwave outputs of the amplifies are merged together by the output couplers and combiner cavity to provide a single amplified output. On the upper and lower sides of the splitter and combiner cavities are rigid metal plates with flat surfaces facing towards these cavities, and on the lower and upper sides of the splitter and combiner cavities are sheet metal dishes. Fixed on the lower plate are concentric annular sheet metal bosses, forming together with that plate a composite metallic wall surface bounding the combiner cavity by an alternation of concentric ridges and valleys. Various of …
