Coaxial units are disclosed for conducting microwaves to and from amplifying apparatus with splitter and combiner cavities. Each coaxial unit comprises an outer conductor, a dielectric sleeve having an unsheathed portion extending forward of the front end of the outer conductor, and an inner conductor pin projecting forward of the sleeve, the pin having a forward portion which is resiliently compressible radially inward. The coaxial unit is coupled to an associated cavity by having its sleeve and pin forward portions, respectively, received in large and small bores respectively formed in metallic plates on opposite sides of the associated cavity. The forward portion of the pin makes direct yieldable-pressure electrical contact with metallic regions around the wall of the small bore at a location adjacent the opening of such bore into the cavity.
