Good practice guide for reliable PIM measurement of RF electrical signals used in communications systems

Popis výsledku v původním jazyce

Passive Intermodulation (PIM) is a form of intermodulation distortion that occurs when two or more RF signals pass through a nonlinear passive element such as corroded connectors or bad cables, which have been thought for long as linear elements. In the past, PIM measurements were only required for a few systems, e.g. satellite communications or the newer generations of mobile communications. However today, PIM problems in cellular communications systems are growing as wider bandwidths are required to transmit higher data rates. The higher signal bandwidths required cannot be achieved if the PIM level exceeds certain specification values. Today, the RF passive components installed in the RF signal path can generate intermodulation signals at -100 dBm or higher, which can degrade the performance of the communication system. Therefore, it is essential to measure PIM accurately to avoid the PIM associated problems.
