3M™ External PIM Absorber 1000 is a composite material consisting of a carrier resin, magnetic fillers and an acrylic pressure sensitive adhesive (PSA). This magnetic material is designed to help reduce radio frequency (RF) electrical currents associated with Passive Intermodulation (PIM), in wireless communications infrastructure.
Applications and Using the 3M™ External PIM Absorber 1000: When 3M™ External PIM Absorber 1000 is applied adjacent to a PIM source, currents flowing to and from the PIM source can be significantly reduced, thereby increasing the Signal-to-Noise Ration (SNR) of the radio access network. The 3M™ External PIM Absorber 1000 is intended for applications in the 600MHz - 4GHz frequency range as the higher loss (u") characteristics of the 3M External PIM Absorber provide for excellent EM (Electromagnetic) field reduction. By helping reduce RF currents with 3M™ External PIM Absorber 1000 before they reach a PIM source, any resulting PIM is significantly reduced. For every 1dB reduction of these currents before they reach a PIM source, third order PIM products are reduced by 3dB. Likewise, fifth order PIM products are reduced by 5dB . The 3M™ External PIM Absorber 1000 is also sold as part of a comprehensive PIM reduction kit: 3M™ PIM Reduction Kit 1000. Key Features: Excellent absorbing performance from 600MHz to 4 GHz Pressure sensitive acrylic adhesive Thin, flexible film format Supplied on a removable liner for easy handling
