(54) Title: METHOD FOR MINIMIZING DISTORTION OF A SIGNAL IN A RADIOFREQUENCY CIRCUIT VGB (57) : The invention relates to a method for minimizing harmonic distortion and/or intermodulation distortion of a radiofre- quency signal propagating in a radiofrequency circuit (L) formed on a semiconductor substrate (1) coated with an electrically insulating layer (2, 2b), wherein a curve representing said distortion as a function of a power of the input or output signal exhibits a trough around a given power (PDip), said method being characterized in that it comprises applying, between the radiofrequency circuit (L) and the semiconductor substrate (1), an electrical potential difference (VG) chosen so as to move said trough towards a given operating power B of the radiofrequency circuit.
