ABSTRACT:
A broad-band, low-reflection energy coupling or decoupling with a coupled cavity line in a traveling wave tube, particularly high-efficiency traveling field tubes, in which a rectangular hollow conductor is not loaded, and has the opposed walls thereof, of minimum spacing and greatest width, tapering in a direction toward the delay line, with the spacing between such walls at the delay line being approximately that between adjacent transverse walls defining respective cells of the delay line, an inductive shield being provided within the hollow conductor and spaced from the line axis, the coupling opening at the hollow conductor having an open angle larger than the corresponding angle of the coupling openings in the transverse walls of adjacent line cells.
