The Pyramid Series from Frankonia are Microwave Absorbers that can absorb RF signals from 26 MHz to 40 GHz. They are based on Frankosorb absorber technology that uses nano thin-film technology for high homogeneity and impedance accuracy. These pyramid absorbers are made from recyclable carbon-free materials and are certified non-combustible/hardly-inflammable which eliminates the need for a sprinkler or fire extinguishing system. They don’t age, droop or lose performance over time and provide long-term stability for over 25 years. These absorbers are hung into rails and are easily removable piece-by-piece. They are available in lengths of up to 2.4 m and are ideal for automotive, commercial, and MIL chambers.
