Abstract
A traveling wave tube is coupled to an output waveguide by an output coupler. The output coupler includes a single integral hollow termination body having an inner surface and an outer surface. The slow-wave propagation structure of the traveling wave tube is joined to the inner surface of the hollow termination body such that the electron beam of the traveling wave tube passes through the interior of the single integral hollow termination body. The output waveguide contacts the outer surface of the opposite end of the single integral hollow termination body with an interference fit.
