PIA - Passive Intermodulation Analyzers
Passive Intermodulation Analyzers from Rosenberger facilitate quick and accurate measurement of the intermodulation characteristics of passive components, such as connectors, cable assemblies, antennas and filters. Precise analysis of the quality of mobile communication infrastructure is also possible.

Rosenberger Passive Intermodulation Analyzers can be customized according to specific requirements by realizing modularized assemblies and cost reductions. Furthermore, Rosenberger provides technical support, product training, calibration as well as maintenance on site.
Product Range
Rosenberger's updated range of Passive Intermodulation Analyzers (PIA) includes Rack and Desktop versions, as well as PIM Site Analyzer alpha. Terminations, adaptors and test cables complete the product portfolio. All analyzers are offered for measurements in various frequency bands.

PIM Site Analyzer alpha

Rosenberger presents its brand new broadband passive intermodulation analyzer "PIM Site Analyzer Alpha" for multi-function on-site tests and measurements of active and passive elements - whether outdoor or indoor systems, RF or Fiber Optic. The new analyzer features PIM detection over CPRI and offers exchangeable filter units.
Desktop Analyzer

has been designed for laboratory and manufacturing applications to quickly and accurately measure the intermodulation characteristics, as well as on tower mounted devices, e.g connectors, cables and other passive components. The transportable PIA can also be used for a precise analysis of the RF infrastructure quality and performance of radio base stations and operates in LTE 700, AMPS, EGSM, DCS, PCS, UMTS, UMTS II / LTE / BRS-EBS and WiMAX frequency bands. They are delivered in a highly shock-proof, stable transport case.

Rack Analyzer
with broadband amplifiers, exchangeable filter units and multiplexers, are specially designed for the use in production lines to measure the 3rd, 5th and 7th order intermodulation, but they also can be applied in R&D, laboratory and calibration centers. Rack types are available as “reflected” types or “reflected & transmitted” types, which operate in LTE 700, AMPS, EGSM, DCS, PCS, TD-SCDMA, UMTS II / LTE / BRS-EBS and WiMAX frequency bands.

Basics - Passive Intermodulation
Passive Intermodulation (PIM) is a nonlinear 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 task for mobile operators, equipment vendors and component manufacturers due to frequency planning in modern communication networks, the usage of high-power transmitters and more sensitive receivers in base stations.

The cause of PIM is very complex and uncertain. Even dirty surfaces, poor soldering and loose connections will cause serious intermodulation. To verify the PIM and look for the root cause, specific test instruments - PIM Analyzers - are required.
