Broadband High Performance RF and Microwave Truncated Absorber

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.
