An Impedance-Based Model for the Evaluation of IM3 in Nonlinear Amplifiers Showing Memory Effects
A simple model that captures nonlinear memory effects inwideband amplifiers is presented in this work. The model defines anequivalent hypothetical load impedance that explains asymmetries, inmagnitude and phase, in two-tone IM products, showing good corre-spondence with measurements. It helps to und...

| Sumario: | A simple model that captures nonlinear memory effects inwideband amplifiers is presented in this work. The model defines anequivalent hypothetical load impedance that explains asymmetries, inmagnitude and phase, in two-tone IM products, showing good corre-spondence with measurements. It helps to understand the intermodula-tion distortion dependence on modulation bandwidth. |
