Method for operating a travelling-wave tube module

摘要

The method involves receiving a radio frequency signal (22) from an antenna (12) of a satellite (10). A determination is made whether the radio frequency signal is amplified. The cathode current of a traveling wave tube (30) is increased to a predetermined value, if the radio frequency signal is amplified. The radio frequency signal is amplified with the traveling wave tube. The cathode current is reduced to a predetermined rest value, if the radio frequency signal is not amplified. An independent claim is included for a traveling wave tube module.
