Abstract
A method and a device for predictive evaluation of intermodulation power in an electronic device in which a predictive function f makes it possible to evaluate in a predictive manner values of power of an intermodulation component produced by an intermodulation distortion of an input signal, characterized in that the predictive function f includes an odd part V obtained by multiplication of an odd function F and of a function G, obtained by composition of a positive real-valued even function g and of a function Q in the form of a real series including at least one term of degree q belonging to the non-integer reals.

Method for the predictive evaluation of intermodulation power in an electronic device, named simulated device, comprising at least one signal input and one signal output, wherein:
- a signal, named input signal, comprising at least two components with distinct frequencies is introduced at an input of said simulated device;
- values, named measured values, representing at least one power of at least one component of a signal, named output signal, produced by said simulated device at an output of said simulated device from said input signal, are obtained by measuring said at least one power;
- power values, named intermodulation powers, of at least one component, named intermodulation component, of an output signal, produced by an intermodulation distortion between at least two components of said input signal, are predictively evaluated from a function, named predictive function f, that is determined using at least two measured values,
- wherein:
- said predictive function f comprises at least one odd part V=F·G, formed by the multiplication
- of an odd function F,
- and of a function G=Q∘g that is the compound
- of an even function, such that g:
- R→R+,
- by a function Q in the form of a series, named real series, comprising at least one term of degree q, with qε{R+−N}.
