| Popis: | A model of the low-frequency fluctuations of the oscillations of an LSA generator produced by accumulation and distribution of space-charge perturbations which occur at local micrononuniformities in the structure of the working region of a Gunn diode is proposed. Flicker fluctuations of the parameters of the nonuniformities are regarded as the primary source of noise. Expressions are obtained for the power spectra of the amplitude-frequency noise of the output signal. The dependence of the noise level on the bias field applied to the diode is analyzed and numerical estimates are given. |
