Abstract

1,031,615. Automatic frequency control systems. BROOKDEAL ELECTRONICS Ltd. March 22, 1965 [April 30, 1964], No. 17952/64. Heading H3A. In an automatic frequency control system for a microwave oscillator, e.g. a klystron 1, a cavity 5 tuned to the required frequency is coupled to the oscillator, for example by a directional coupler 2. The resonant frequency of the cavity 5 is modulated by means of a crystal diode 9 coupled to the cavity and fed by a signal from the modulation oscillator 10. Any mistuning of klystron 1 will result in a modulation of the microwave signal, and this modulation is detected and compared in a phase comparator 11 with a reference signal from modulation oscillator 10 to produce a control signal for the klystron 1.
