Passive intermodulation (PIM) can degrade the transmitted signal quality by acting as an interference signal resulting from subsystem, components, material, poor mechanical connections, and sometimes the physical layout when they fall inside the receiver bandwidth. In a multicarrier system, signals sharing the same transmission path can mix together generating PIMs [1]. This can happen in active devices as well as passive components. Passive components include antennas, cables, connectors, power dividers, and mixers. Typically, components with higher ferromagnetic content contribute to the generation of PIMs. PIM products are generated on space vehicles also, and direct measurement of PIMs is extremely difficult. In this paper an indirect method of verifying that PIM budget is not exceeded is discussed.
