Wide-band hybrid pyramid em absorbers

wide band hybrid pyramid em absorbers icon 1


The 3630 series Wide-band hybrid pyramid EM absorber and is available in 2 sizes. It shows good absorption performance in the wide band between 30 MHz and 18 GHz when combined with 6.3 mm thick Ferrite absorber tiles (Part nr. 3600-63). The hybrid pyramid absorber is made out of ferrite and carbon powder and is tuned for perfect performance over Ferrite absorber tiles.

Due to this special characteristic, the product is suitable for building a small anechoic chamber to get a bigger space than built with foam pyramidal absorber. Also, it can increase the frequency from 1 GHz to 18 GHz as compared to a standard anechoic chamber that only has Ferrite absorber tiles.
