Active Components Based on Dynamic Negatrons

The active elements based on dynamic transistor negatrons (circuits with negative activedifferential resistance) are introduced. The principles of dynamic transistor negatronssimulation has been developed on the basis of non-linear charge model. Parameters,which characterize non-linear mode of dynamic transistor negatrons, are derived. Nonlinearequivalent circuit and Volterra series are used to calculate parameters of negatrons.Particular attention is devoted to the frequency mixers and frequency switches. An experimentalfrequency mixer has been described, that has confirms the theoretical predictions
