These 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 (BPA) is a low density polyurethane foam, filled with high loss dielectric material in open cell structure and finished with light blue paint. The dimension is 60cm x 60cm with 5” to 36” 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.
