Research on the Non-Linear Response Characteristic of Magnetron to Anode Voltage Ripple

This paper proves that a 2.45 GHz band continuous-wave magnetron has the non-linear response characteristic to the frequency of anode voltage ripple. We deduce the output voltage and frequency expression of a free oscillating magnetron under the influence of high-frequency anode voltage ripple. The output reveals that a magnetron can realize frequency shifting of high-frequency ripple. Sidebands will appear on the both sides of the central frequency of free oscillating magnetron. The frequency difference between sideband and the center is the ripple frequency. Finally, an experimental system is accomplished to testify the theoretical derivation. This research is promised to apply to the simultaneous information and power transfer system based on magnetron.
