PROBLEM TO BE SOLVED: To provide a small/thin traveling-wave tube capable of reducing the weight and cost of an array antenna. SOLUTION: Multiple-stage iris coupling is formed in a waveguide of an output circuit 123 to provide functions of a band-pass filter and a band-reject filter for the output circuit 123, whereby spuriousness generated by nonlinear distortion of this small/thin traveling-wave tube 1 is removed, and the need of a filter conventionally installed in a subsequent stage of the small/thin traveling-wave tube 1 for removing the spuriousness is obviated.
