Abstract
According to this invention, a traveling-wave tube amplifier includes a traveling-wave tube having a multistage depressed collector and a power supply for applying operation voltages to the traveling-wave tube. A body voltage (Vb) for a cathode of the traveling-wave tube is set to be lower than a small-signal synchronous voltage (Vbs) at which a small-signal gain of the traveling-wave tube is maximized. As a result, a tube efficiency (.eta.t) of the traveling-wave tube can be increased and an efficiency of the traveling-wave tube amplifier can be increased as compared with a conventional device.
