Abstract

A Ga As FET oscillator includes an FET having gate-drain and source connections. A tuned circuit is connected to the FET gate. Bias voltage is supplied to the FET. A parallel-connected resistor and capacitor is connected to the FET source. A Schottky diode is connected across the FET gate-source junction and the parallel connected resistor and capacitor, with its anode connected to the FET gate and its cathode connected to the resistor and capacitor. The Schottky diode limits the positive voltage across the gate-source junction of the Ga As FET to prevent gate-source current flow.
