Passive Intermodulation Test Solutions

For all Applications.
Made in Germany.

High-speed data transmission in today’s global mobile communication 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 for Your Application

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 of Low-PIM components as well as PIM T&M solutions
for all applications:

  • R&D / Test Lab
  • Production Environment
  • Site Testing

PIM Site Analyzer alpha

The Rosenberger portable and multifunctional broadband PIM Site Analyzer alpha provides the best alternative of performing the most precise and efficient PIM tests on site.

The PIM Site Analyzer alpha consists of a single Master Unit with band-specific, interchangeable filter units, since the form factor of the filter units is the same. Take out one filter unit, e.g., 900 MHz, and replace with another filter unit, e.g., 1800 MHz, without any calibration of the filter unit, potential adaptors, test cable, or operational mode(s). Future-proof Plug and Play concept covering 700 to 2700 MHz

Key Features

  • Broadband Base Unit 700 - 2700 MHz with field interchangeable, band-specific filter units
  • Stressed PIM tests – continuous wave (CW) signal simulates real operating conditions of the base station (in conformity with IEC 62037-1)
  • Outstanding PIM performance < -125 dBm (< -130 dBm typ.)
  • No on-site calibration
  • Accuracy of < 0.3 m for PIM Distance to Fault (DTF) measurement
  • Future-proof for upcoming bands
  • Hardware ready for later CPRI SW upgrade

Additional Features

  • In-built WiFi for remote control via optional 10" Android tablet
  • Operation via batteries or external power supply
  • VSWR/return loss measurements
  • Antenna isolation measurement
  • Integrated spectrum analyzer
  • 12" touchscreen
  • Intuitive software operation
