Abstract:
In a linear beam tube having an operating frequency band, a load network comprising:an output waveguide for transmitting an output signal generated by said linear beam tube, said output waveguide having a first respective end coupled to an output section of said linear beam tube and a second respective end adapted for coupling to a load; andat least one resonant cavity electrically coupled with said output waveguide through an inductance whose component of series susceptance is substantially greater than the corresponding component of shunt susceptance, said at least one resonant cavity producing a reflection of power within said output waveguide and having a resonant frequency tuned outside of an edge of said operating frequency band of said linear beam tube, said resonant frequency being of such a value so as to provide an impedance mismatch in certain portions of said operating band.
