Abstract

A method of locking IMPATT oscillators by illuminating the IMPATT diode with a low-power laser beam, amplitude modulated at microwave frequency, is described. A large-signal theory of IMPATT operation which includes the effect of reverse saturation current modulation by the laser beam is presented and predictions of locking ranges obtainable are made. The analytic theory is supplemented by a large-signal computer simulation of an IMPATT oscillator under microwave-modulated illumination. Finally experiments under way at present to test these predictions are described.
