What is the RF connector PIM value


Regarding the main performance PIM value (passive intermodulation) in the RF connector, you may only know that there is this performance value, but what is the use of it, and what effect it will have on the performance of the RF connector. How much loss is there in the signal transmission of the device. So what is the PIN (Passive Intermodulation) that Xiaotian will tell you?
The PIM value (Passive Intermodulation) is a distorted signal generated by mixing two or more different frequency signals into a passive device due to the nonlinearity of the connection point or material.

The generation of interference is related to the local downlink frequency, which can cause the uplink frequency band to rise when multiple systems share the infrastructure. The impact of PIM on network quality is very serious, especially for broadband systems such as UMTS or LTE. PIM interference can cause Reduced receiver sensitivity, dropped call rate, increased access failure rate, premature switching, reduced data transmission rate, and reduced system coverage and capacity.
RF interference, including antennas, TMAs, antenna duplexers, duplexers, lightning arresters, cables and connectors. In addition, when the antenna system is radiated with high power, loose mechanical connections and rusted surfaces can also cause PIM interference.
