This paper describes experimental studies of passive intermodulation due to metal-metal contacts. These studies cover the in uence of roughness surface pro le and of the thin native oxide layer on PIM value versus contact axial forces. A complete description of a dedicated test bench used during di erent studies is done. Moreover, obtained results are compared to observations published earlier.
