Abstract
1,217,744. Gunn effect oscillators. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 7 March, 1968 [1 April, 1967], No. 11124/68. Heading H3T. A pulse operated Gunn effect oscillator comprises means for applying to a Gunn effect sample a keyed or pulsed D.C. bias voltage and means for also applying to the sample a microwave frequency signal, approximately equal to the initial oscillation frequency of the sample, at least during the periods in which the applied D.C. bias voltage is passing through its critical value to cause the sample to begin oscillations such that the on set of oscillations in the sample occurs in a fixed time relationship with the applied D.C. bias voltage. The microwave signal is of an amplitude considerably less than that of the produced oscillations. The output may be obtained from a circulator and the microwave frequency signal may be pulsed.
