In order to study the PIM power level as a function of the tightness of the junction, the roughness of the waveguide surface, the thickness of the oxide layer on the metal surface and the input carrier power, firstly developed an equivalent ciurcuit model based on the rough surfaces contact model and then calculated the third order PIM power level using power series method.
