Passive Intermodulation Testing


PIM Test Solutions for All Applications. Made in Germany.

High-speed data transmission in today’s global mobile communications networks demands high efficiency of network infrastructure. Passive Intermodulation (PIM) in a network can cause serious interferences and significantly degrade the network quality and impact KPI figures.


Best-in-Class PIM Test Equipment

The cause of Passive Intermodulation is very complex and uncertain. It can be caused by low-grade transmission line components or even loose connectors, dirty surfaces, magnetic materials or the surrounding environment like a rusty roof. As a global leader of RF connectivity solutions, Rosenberger has a strong expertise in manufacturing low-PIM components as well as PIM Test and Measurement solutions for all applications:

  • Site testing
  • Testing in production environment
  • Test lab and product design environment


Reduce Test Time and Connection Cycles

Rosenberger provides the answer with an innovative multi-port, multi-frequency PIM testing solution, ensuring precision testing while maximizing on time savings and ROI.

  • Modular design
  • Multiple base units and filters
  • Combiner unit
  • Direct connection to DUT via PIM test cable and quick-lock adapter

Example of a high-band test configuration:

  • 1 connection towards DUT on 4 high-band ports
  • PIM test 4 high-band ports, 3 different bands simultaneously in one connection
  • Overall test time ~ 30 seconds in sweep mode (PIM test including cable connection)


  • Reduce test time and connection cycles
  • Improve testing efficiency
  • Optimize utilization of test equipment (totex)
  • Reduce complexity of test setup
  • Minimal cabling required
  • Easily expandable
  • Capex and opex savings

Reliable Classification and Detection of External PIM

The versatile Rosenberger 2-port PIM testing solution combines the functionality of a traditional one port test system with a new 2-port test system to distinguish internal PIM-sources from external PIM-sources.

  • One port: same power of f1 and f2 at PIM-source. If PIM is found, source can be internal (transmission path) or external (beyond antenna).
  • Two ports: f1 to Antenna 1, f2 to Antenna 2. No PIM on transmission path possible. If PIM is found, it must be external.

PIM Hunting

Furthermore the additional RX port on the 2 port filter unit enables the built-in receiver. In combination with a PIM hunting probe it is possible to detect external PIM-sources around the antennas. With this integrated solution an additional spectrum analyzer to operate the PIM hunting probe is not needed.


  • PIM test under typical scenarios (e.g. 2 antennas using different wavebands)
  • Configurable menu (1 or 2 port measurement)
  • Clearly differentiate internal from external PIM
  • Additional RX port for connection of test probe for external PIM detection
  • Integrated DTF module
  • No separate spectrum analyzer needed
  • Adjustable PIM level beep tone via bluetooth speaker or remote tablet
