Test Equipment Description

C-RAM PIM 645 FR is a line of flame retardant indoor isolation foam sheet material, comprised of urethane foam and a lossy carbon loading. CRAM PIM 645 FR absorbs RF microwave energy across 700 MHz through 3 GHz. frequencies. C-RAM PIM 645 FR has proven to be ideal for PIM reduction and isolation between antennas; it can also be used to cover fences to de-couple adjacent antennas, and shield or isolate equipment. The open-cell structure permits airflow freely through the absorber.
