Nonlinear example circuit: an ideal voltage source driving the series connection of a nonlinear and linear resistor.

FIG. 2.

(a) Comparison of the power dependence of the intermodulation product of the nonlinear resistor characterized by Eq. (1) when in isolation (dashed line) and when in series with a linear resistor (solid line). (b) Frequency spectra of the current produced by the nonlinear resistor in isolation, showing a completely cubic response. (c) Due to the interaction between the linear and nonlinear resistors, the nonlinear behavior of the complete circuit composed of the linear and nonlinear resistor is multiordered.

Measured vs simulated behavior of the nonlinear distortion product produced by a SMA connector in a microwave resonator (inset).

FIG. 4.

(a) Plots the measured power in the third-through 13th-order intermodulation products along with the linear-nonlinear interaction model’s prediction. (b) Measurement of the decrease in nonlinear distortion in a SMA connector with increasing input power in a two-tone test, along with the model fit given by the circuit in Fig. 1, where is characterized by a purely third order nonlinearity (dashed line) and a second-plus-third-order nonlinearity (solid line).
