摘要
A circuit arrangement protects against thermal overload as a consequence of impermissible operating conditions in traveling wave tube amplifiers having multi-collector traveling wave tubes. At least one measuring device is provided for measuring the collector current at at least one collector of the traveling wave tube and, in response to measuring a prescribed current threshold, the cathode current of the traveling wave tube is regulated back by way of a control device or is disconnected by way of a control logic circuit.
