ABSTRACT:
A high-frequency oscillator including an oscillation circuit (1) having a quartz crystal (X) and an amplifying element (Q.sub.2), a power amplifying circuit (3) for amplifying the output of the oscillation circuit, and a control system (Q.sub.7, 6) for varying a bias voltage of the amplifying element to thereby control the output power of the power amplification circuit. The control system comprises an FET (Q.sub.7) connected at the drain thereof to the amplifying element, and a control circuit (6) for applying a control signal to the gate of the FET.
