(Prior art) As shown in Figure 6, the operating principle of a traveling wave tube is that the electron flow (B) emitted from an electron gun (A) in a vacuum moves in the same direction as the electron flow (C). ) Microwaves are amplified by utilizing the interaction that occurs between the electric field on the axis and electrons when the velocity of the radio wave on the axis is approximately equal to the velocity of the radio wave on the axis. The electron stream is finally collected at a collector (D). The features of this traveling wave tube are that the slow wave circuit (C) has a large number of waves on the axis, which increases the interaction with electrons and provides high gain, and that there are few places where energy accumulates in the circuit.
The amplification bandwidth is wide. Therefore, an attenuator (E) is used to prevent unnecessary reflected waves occurring anywhere in the wide bandwidth.
