- Removable Case Lid
Leading Global wireless carriers use PIM analyzers to improve the quality of their networks. Low PIM installations are particularly important when wireless networks operate close to full cell capacity. Signal degradation affects revenue streams directly due to reduced data capacity.
Field use demands ruggedized yet accurate, test instruments. Our portable PIM testers are designed for this environment and an withstand tough conditions. An embedded module for accurate Distance to Fault (VSWR) and Distance to PIM measurements is available as option. Patented technology, provides very accurate indication of PIM sources.
Passive Intermodulation – PIM
Passive Intermodulation (PIM) is an unwanted mixing effect caused by non-linearity of passive components in the RF path of telecommunication systems. PIM diverts signal energy to other frequencies (spurious signals). This can generate interfering signals that may fall into receiving bands causing serious degradation of system performance.
Causes of PIM
- Dissimilar metals with different electrical properties as well as corroded components and structures.
- Ferromagnetic metals like iron, nickel and steel, show hysteresis effects when RF energy is applied.
- Irregular contact areas, even on a microscopic scale, cause an inconsistent flow of electrons, generating inhomogeneous electrical fields.
- Spark discharges that may happen by accidental “hot” connections and disconnections create craters on the connectors’ surfaces and lead to chemical reactions
RF Components that may cause PIM
- Cables
- Connectors
- Antennas
- Attenuators, Loads
- Surge Protectors
- Filters, Diplexers, Duplexers
- Combiners, Splitters, Couplers
