An unstable magnetron RF source for driving an accelerator cavity at high power is stabilized using ferroelectric fast reactive tuning. The magnetron output is converted to a selected reference frequency with negligible insertion loss. The conversion is achieved by modulating the magnetron's frequency, such that the modulation converts the magnetron's output to the exact reference frequency. The method also allows simultaneous amplitude and phase control.

Comments
The high voltage driver of the ferroelectric tuner is impossible to realize in the scheme which is described in the paper. A modified scheme with a realizable driver will be studied.
