Abstract: By using an EIP source lock counter, a frequency of a Gunn oscillator is stabilized. This increases the frequency stability of a circuit. An oscillation output of the Gunn Oscillator is supplied to the EIP source lock counter, and a phase lock signal indicative of a phase shift of the oscillation frequency from the EIP source lock counter relative to a preset reference frequency is supplied to a driver circuit. The driver circuit includes level shift circuit which level-shifts the phase lock signal thereof. A phase compensation circuit in the driver circuit boosts a gain as well as advances a phase at a high frequency region. The current amplifier circuit amplifies a current amplitude of the output of the level shift circuit, and the amplified output therefrom controls an oscillation frequency of the Gunn oscillator using negative feedback.
