Mechanical fastener arrangements in spatial power-combining devices and related methods

Abstract

Power-combining devices and, more particularly, mechanical fastener arrangements in spatial power-combining devices and related methods are disclosed. Mechanical fastener arrangements promote 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 mechanical fastener arrangements attach conductors of input and/or output coaxial waveguide sections to center waveguide sections with mechanical fasteners. Heads of mechanical fasteners are positioned within center waveguide sections and nuts secured to the mechanical fasteners are in positions that are outside center waveguide sections.
