Passive Intermodulation Analyzers (PIAs) are professional measurement instruments which are characterized by very low self-intermodulation and high power level signal output. Their high accuracy receiver allows fast and precise measurements of the 3rd, 5th and 7th order intermodulation of passive devices under high-power conditions, e.g. connectors, cable assemblies, antennas, filters, and other passive components.
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. If a PIM with sufficient magnitude generated from a transmitter falls within an adjacent receiver channel, it causes serious interferences to the base station receiver and will significantly degrade the network quality of service. The cause of PIM is very complex and uncertain. Even dirty surfaces, poor soldering, and loose connections will cause serious intermodulation. Hence, in theory, it cannot be calculated nor cannot be simulated by software. To verify the PIM and look for the root cause, specific test instruments are required.
