Ferrite absorber tile is the industry standard solution and exhibits excellent overall performance versus cost.
Our 3600 series Ferrite absorber tile is the industry standard solution and exhibits excellent overall performance versus cost. It is an attractive alternative to traditional, large, foam-type absorber materials for new anechoic chambers or for upgrading existing rooms for radiated emission and immunity measurements.
These tiles are a quite recent development. They are used when relatively high absorption is required together with a compact solution (-15 to -25 dB @ <100MHz) - approximately 4 to 7 mm vs. 2400mm for foam absorbers. They also provide a reliable and compact solution for attenuating plane-wave reflections in shielded anclosures.
UHF ferrite absorber tile is made of a sintered ferrite in the shape of a square tile. The dimensions are 100 x 100mm or 200 x 200 mm with a thickness of 6.75mm.
The tiles can easily be screwed on to a wall individually, inserting screws through the 10mm hole, or mounted by means of adhesive. The tiles are optionally available in panel format. The tiles are surface-ground on all sides to precise mechanical tolerances, minimizing gaps between adjacent tiles to ensure maximum low-frequency performance.
The tiles provide excellent electromagnetic absorption in the UHF band. The product works well in a Dark box for mobile phone inspection and EMC anechoic chambers, and it is also suitable for high buildings to prevent TV ghost.
