Abstract

In this paper, the generation of passive intermodulation (PIM) at rectangular waveguide flange connections is investigated. An exhaustive test campaign has been followed in order to provide understanding on the physics lying behind such a phenomenon. In particular, the PIM response of the system has been studied as a function of parameters such as the applied torque to the flange screws, the total combined input power level and the power ratio between the carries. It is found that, in some situations, the intermodulation response differs from its expected behavior. An interpretation of such discrepancies is given as well
