Claim 7:
8. A spatial power-combining device comprising:
a center waveguide section comprising a plurality of amplifier assemblies, wherein the plurality of amplifier assemblies form a first end and a second end;
a first coaxial waveguide section attached to the first end, the first coaxial waveguide section comprising a first outer conductor and a first inner conductor that form a first channel therebetween, the first inner conductor comprising a first portion and a second portion that are separate elements and the second portion is attached to the first portion;
a second coaxial waveguide section attached to the second end, the second coaxial waveguide section comprising a second outer conductor and a second inner conductor that form a second channel therebetween; and
a mechanical fastener at least partially arranged within the center waveguide section such that the plurality of amplifier assemblies are arranged radially around the mechanical fastener, wherein a threaded portion of the mechanical fastener is threaded into and secured to the first portion of the first inner conductor and a head of the mechanical fastener is fixed and enclosed within the second inner conductor of the second coaxial waveguide section.
