On the possibility of increasing the automodulation threshold in a gyro-oscillator with backward-wave and coupled electrodynamic systems

摘要

We have studied the possibility of increasing the onset threshold for automodulation caused by a growth in the beam current in gyro-backward-wave tubes. It is shown that, by using a coupled electrodynamic system, it is possible to significantly shift the region of threshold currents for the automodulation onset so as to increase the output power in a singe-frequency generation regime.
