Modulation of the output power of semiconductor microwave oscillators by changing the voltage in bias circuit

The use of the scheme of coherent signals subtraction (the synchrosignal and the synchronized oscillator output signal) for realization of the simple method of control of the output power of semiconductor microwave oscillators on the example of Gunn oscillator by the changing the bias of an active element has been proved theoretically and experimentally. The change up to 40 dB of the oscillator output power at the constant output frequency, when bias changes on 2.7%, has been achieved.
