Résumé
The susceptibility of RF devices to the third order intermodulation (IM_{3}) is studied. In this paper, we propose an alternative of the classical two-tone test by using tones of not equal amplitude injected on RF devices. This new method aims at enhancing the intermodulation distortion characterization. We evaluate this method by measuring in a conducted f_{2}-f_{1} mode the f_{1}-f_{2} IM_{3} responses reflected by RF systems, namely a modem and a walkie-talkie. IM_{3}
