These PU foam bases pyramide absorbers are the most popular solution for 3m, 5m and 10m EMC chambers in the market.
These absorbers are the most popular solution for 3m, 5m and 10m EMC chambers in the market. They are composed of pyramidal, full tip SAM or truncated SMT pulsing the matching layer to separate the pyramidal part from the ferrite part. Through optimization, this product has a superb performance across 30MHz to 18GHz. The ferrite performes from 30MHz to 1GHz and the foam performes above 1GHz.
Prototypes are made and the design is tested. Results become part of a valuable feedback loop for refining our design further.
Broadband Pyramidal Absorber is a low density polyurethane foam, filled with high loss dielectric material in open cell structure and finished with blue paint.
The general base size is 60cm x 60cm with 50mm to 1200mm height pyramidal. It’s flexible and light weight, can be attached on the wall easily. It is a high performance broadband RF absorber and widely used for Anechoic Chambers.
Generally an environmental protective adhesive is used to paste the absorbers on the shield body (inside of the Faraday cage); when the absorbers’ height is below 500mm, Velcro installation can be applied; furthermore, we can also adopt the fasteners to install the absorbers, which would facilitate the replacement of absorbers and the relocation of chambers.
