ABSTRACT:
A traveling wave tube employing a coupled-cavity type slow-wave circuit and having high gain and efficiency over a wide operating frequency band as a result of a design in which the slow-wave circuits are separated into first and second (i.e. fore) and output slow-wave circuits connected to one another by sever sections containing nonreflectivity terminated waveguides. The synchronizing frequency of one of the fore slow-wave circuits is selected to be different from that of the other fore slow-wave circuit and the output slow-wave circuit. The aforesaid slow-wave circuits incorporate coupler cavities at the opposite ends thereof and a plurality of main unit cavities positioned between the coupler cavities. The desired synchronizing frequencies are obtained by controlling the dimensions of the cavities, interaction gaps, apertures and coupling irises.
