US 12,525,696 B2 · Structural arrangements for spatial power-combining devices

Abstract

Power-combining devices and more particularly spatial power-combining and related structural arrangements are disclosed. Such structural arrangements involve mechanical connections between center waveguide sections and input and/or output coaxial waveguide sections that provide scalable structures for different operating frequency bands, improved mechanical connections, and/or improved assembly. Exemplary structural arrangements include structures that extend through center waveguide sections and into input and/or output coaxial waveguide sections, integrated mechanical structures within the center waveguide section, compression fit arrangements, dielectric inserts arranged within channels of coaxial waveguide sections, and/or various combinations thereof.

Dependent claims

A spatial power-combining device comprising:

a center waveguide section comprising a plurality of amplifier assemblies, wherein the plurality of amplifier assemblies forms a first end and a second end, and wherein each amplifier assembly of the plurality of amplifier assemblies comprises:
an input antenna structure, an amplifier, and an output antenna structure;
and
a body that supports the input antenna structure, the amplifier, and the output antenna structure, wherein a portion of the body that is proximate the first end forms a first slot that is entirely spaced from the first end, and wherein the first slot of each amplifier assembly of the plurality of amplifier assemblies forms a first radial cavity that is spaced from the first end;
a first coaxial waveguide section attached to the first end by a first mechanical fastener;
and
a first nut that is arranged within the first radial cavity, wherein the first nut receives a portion of the first mechanical fastener.
