For the construction of a small anechoic chamber, to get a larger space than one could build with pyramid-shaped absorbers. Performs very well in wide band (30 MHz to 18 GHz).
3630 Wide-band hybrid pyramid EM absorbers
The 3630 series Wide-band hybrid pyramid EM absorber is an 80 mm high absorber that measures 100 mm x 100 mm. It has good absorption performance in the wide band between 30 MHz and 18 GHz when combined with 6.3 mm thick Ferrite absorber tiles (Part # 3600-63).
The hybrid pyramid absorber is made out of a carbon-loaded polystyrene 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. It can also increase the frequency from 1 GHz to 18 GHz as compared to a standard anechoic chamber that only has Ferrite absorber tiles.
