Hybrid Foam/Ferrite Absorber for EMC Chambers

HYBRID RF ABSORBER FOR LOW FREQUENCIES

C-RAM HFP (390-6) DOWNLOAD TECH SHEET PDF
C-RAM HFP is a hybrid RF absorber designed for low-frequency EMI test rooms and anechoic chambers. The “hybrid” construction consists of specially-formulated urethane foam pyramidal or wedge absorber panels mounted on top of ferrite tiles, resulting in almost all the performance normally seen with ferrite tiles alone in the 30 – 1000 MHz range, plus up to -30dB reflectivity from 1 – 20GHz. For many testing applications, C-RAM HFP achieves comparable performance in less than half the volume occupied by conventional pyramidal absorbers.

      One should note that the pyramidal foam component of C-RAM HFP is specially designed to match the impedance of the ferrite tiles, and is not the same material as standard C-RAM SFC pyramidal foam absorbers. Customers can discuss application details with Cuming Microwave engineers to arrive at an optimal solution for their application.
