PIM Testing
In today‘s global communication networks, the infrastructure must be highly efficient to ensure high-speed data transmission.  Passive intermodulation can be caused by various factors – low-grade transmission line components, loose connectors, dirty surfaces, magnetic materials or by the surrounding environment. A precise analysis of the quality of mobile communication net- works is therefore necessary.

To ensure optimum network quality and to avoid serious interferences by passive intermodulation (PIM), Rosenberger provides high-quality PIM test equipment for a wide range of applications – R&D, test labs, production environment, and site testing.

Passive Intermodulation

Passive Intermodulation (PIM) is a non-linear response of two or more signals of different frequencies mixing together in a passive device, e.g., antenna, cable, connector or splitter. Today, PIM has become a very serious, and challenging issue for mobile operators, equipment vendors, and component manufacturers due to frequency planning in modern communication networks, the usage of high-power transmitters and the usage of more sensitive receivers in base stations. If a PIM with sufficient magnitude generated from a transmitter falls within an adjacent receiver channel, it causes serious interfe- rences to the base station receiver and will significantly degrade the network quality of service.
