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.
Claims13
An electronic tube having an output lead which is required to provide input to a waveguide, said tube comprising a hollow output arm through which said output lead passes, and an end cap provided at the end of said hollow output arm and to which said output lead passes, said end cap including a tubular wall which provides a window for communication with said waveguide and a metal plate affixed to the tubular wall, and the arrangement being such that, when entered through an entry hole in one wall of said waveguide, said metal plate of said end cap abuts the inner surface of said waveguide opposite said entry hole.
