Abstract
A travelling wave tube has an output lead passing through a tubular output arm to a cap provided at the end of the arm. The cap has a cylindrical wall of ceramic material and is completed by a flanged plate of metal, to which said output lead is attached. When coupled to a waveguide, the travelling wave tube output arm enters an entry hole in one wall of the waveguide while the cap thereof abuts a matching ridge provided on the interior of the opposite wall of the waveguide. A small recess in the ridge locates the cap, the cylindrical wall of which acts as a window through which travelling wave tube output may pass into the interior of said waveguide.
