Abstract : Presents the derivation of a method for determination of the properties of tandels (temperature autostabilized nonlinear dielectric element) in a parametric frequency multiplier, and experimental results are given. The tandel properties are expressed by means of an equivalent circuit formed by a parallel combination of a nonlinear lossless capacitor and a nonlinear resistor. The dependence of the capacitance and the conductance of the equivalent circuit on the voltage is expressed by the first terms of a power series. The expansion coefficients of the nonlinear capacitance and conductance into the power series are calculated from the measured values in the parametric frequency tripler with a tandel and are plotted on diagrams as a function of the available power of the source and the ambient temperature. All measured and estimated values depend solely on the temperature and supplied power.
