Abstract
A method for operating a traveling-wave tube module of a communication satellite involves receiving of a high-frequency signal from an antenna of the satellite and determining that the high-frequency signal is to be amplified. The cathode current of a traveling-wave tube is increased to a predetermined operating value if the high-frequency signal is to be amplified and the high-frequency signal is amplified by the traveling-wave tube.
