Background
PIM, also called "passive intermodulation", is one of the important indexes for checking the performance of the base station antenna, and the impact of PIM on the network quality is very serious, especially in a wideband system such as UMTS or LTE; PIM interference can cause the sensitivity of a receiver to be reduced, the call drop rate is increased, the access failure rate is improved, the data transmission efficiency is reduced, and the coverage range and the capacity of the system are also reduced. In addition to the effects of the individual body devices of the antenna itself; the external test environment is also an important interference source for the PIM; especially for rf cables and connectors used for testing, when the antenna system radiates with high power, the loose mechanical connection and the bending radius of the cable, the maximum allowable pulling force and the aging characteristics of the cable all cause serious interference to the PIM test.
Therefore, for the troubleshooting of radio frequency cables and connectors, the protection is crucial to maintaining good PIM indexes, and the existing PIM test radio frequency cable is not effectively protected, resulting in a lower service life of the cable.
