Description:

The MW82119A is a Battery-operated, high power Passive Intermodulation (PIM) testing solution for the major wireless standards in use around the world. The PIM Master’s small size and light weight, combined with battery operation, make it the ideal solution for verifying PIM performance at difficult to access sites such as Remote Radio Head (RRH) installations or indoor Distributed Antenna Systems (DAS).


PIM is a form of intermodulation distortion that occurs in passive components normally thought of as linear, such as filters, combiners, surge protectors, cables, connectors, and antennas. However, when subject to the high RF powers found in cellular systems, these devices can generate spurious signals.


PIM shows up as a set of unwanted signals created by the mixing of two or more RF signals in a non-linear device, such as in a loose or corroded connector, or in nearby rust. Other names for PIM include the "diode effect" and the "rusty bolt effect".

Many symptoms could be indicators of PIM problems. These include:

Receiver desensitization (raised noise floor)
Rx Diversity alarms
Spectral regrowth in the transmitter mask
Excessive dropped/blocked calls
Cell site coverage shrinking
Complaints of interference from neighboring cell site owners
