Broadband High Performance RF and Microwave Truncated Absorber

DMC Truncated Series foam absorbers are mainly used in EMC Chambers. RF Truncated Absorber are made by removing 20% Pyramid absorber tips to give same performance as Standard Pyramid in low frequency range. The advantage of RF Truncated Absorber  are to provide large working space inside chamber , stronger resistance capability against mechanical damage and eliminating drooping of tips.
