An energy supply unit for a traveling wave tube is configured to transform a first voltage present at a low voltage interface into a second voltage providable at a high voltage interface. The second voltage is greater than the first voltage and corresponds to a required operating voltage of the traveling wave tube. The energy supply unit is configured to receive a signal pattern via a signal input interface and to output a control signal via a control interface to the traveling wave tube for operating the traveling wave tube based on the signal pattern and to gradually and/or iteratively align or adapt the control signal to the signal pattern being present at the signal input interface when changing an operating mode of the traveling wave tube. A power draw at the beginning of the switched-on state may increase slowly and voltage drops at the high voltage supply may be minimized.

Energy supply unit for a traveling wave tube

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.

Method for operating a traveling-wave tube module

A control apparatus for an earth-distant-platform includes a control unit, which includes with a control input and a control output, and a memory element. The memory element contains a plurality of operating value parameter sets for an RF transmit amplifier unit. The control input receives a control signal and, dependent on the control signal, the control unit selects an operating value parameter set from the memory element. The control output controls an energy supply unit and/or a preamplifier/linearization element using the selected operating value parameter set such that the RF transmit amplifier unit is operable in a defined operating state.

Control apparatus for a transmit amplifier unit

A method for operating an amplifier module of a communication satellite involves establishing an undesired state of the amplifier module, storing state data, which indicate the undesired state, in a nonvolatile memory of the amplifier module, after the undesired state has been established, and deactivating the amplifier module after the storage of the state data.

Method for operating an amplifier module of a satellite

A method for operating an amplifier module of a communication satellite involves saving at least one configuration parameter of the amplifier module in a non-volatile memory designed to store the configuration parameter when the amplifier module is not energized. The configuration parameter can be loaded from the non-volatile memory and used to configure the amplifier module.

A power-supply device and amplifier are joined by way of a mechanical/thermal interface to form a unit. Electrical connections between the power-supply device and the amplifier chamber are run within this shared unit. A shared electrical interface is provided for external control- and supply signals, respectively.
