Flexible Absorbent Material

(FAM)

 

    

FAM is a thin and flexible material, include soft rubber type and flexible sintered ferrite sheet with higher permeability. It can be cut any shape easily, freely arranged in space and provide effective EMI suppression in a wide frequency range (1MHz to 18GHz). Also can be a solution for RFID (Radio Frequency Identification) system on metal. It suitable for LF(125/134.2KHz) and HF(13.56MHz) bands on metal environment. It also works well in NFC (Near Field Communication)  technology application and Wireless Charger (WPC/Qi).

VHF Ferrite Absorber Tile

(FAT-100)

 

    

VHF Ferrite Absorber Tile (FAT-100) is a sintered ferrite with square tile shape. The dimension is 100 x 100mm and thickness is 5.5mm or 6.3mm with a 10mm hole, can be screwed on the wall easily. The common application is for EMC Anechoic Chambers to provide excellent electromagnetic absorption performance in the VHF band. It’s also suitable for high building to prevent TV ghost.

Double Layer Ferrite Absorber Tile

(FAT-DL)

 

    

Double Layer Ferrite Absorber Tile (FAT-DL) is a special design for small EMC Anechoic Chamber to get excellent electromagnetic absorption performance in 30MHz - 2GHz. It consists of a 21mm gap between two pieces 100 x 100 x 3mm sintered ferrite tile, can be glued on the wall easily. Due to this special double layer design, it provides more wide frequency range than one-piece ferrite tile design, even in a small size anechoic chamber.

Wide Band Pyramidal Absorber

(WPA)

 

     

Wide Band Pyramidal Absorber (WPA) is a 80mm high absorber with 100 x 100 mm size. It has a good absorption performance in wide band between 30MHz and 18GHz when combine with 6.3mm Ferrite Tile. Due to this special characteristic, it’s suitable to build a small anechoic chamber to get a bigger space than build with Foam Pyramidal Absorber. Also, it can increase the frequency from 1GHz to 18GHz at a standard Ferrite Tile only anechoic chamber.
