PYRAMIDAL RF MICROWAVE ABSORBERS

FU-SE absorber product line is a complete range of high performance pyramidal microwave absorbers.

Available in wide range of thickness and absorbencies. Variety of thickness gives the chamber designer an opportunity to choose grades appropriate for specific frequencies and incidence angles.

Constructed using low density, flexible foam, impregnated with a carbon black ferrite formulation to achieve the desired electrical performance

The pyramidal structure gives it the geometrical matching and the carbon dispersed gives the attenuation required at near normal incidences

Provide engineers with the building blocks needed in the design and construction of RF absorbing surface used in anechoic chambers, antenna assemblies and microwave measuring facilities.

• Absorption over a wide frequency range.
• Long product life.
• High performance, up to -50 dB attenuation.
• These absorbers are supplied with a fire retardant finish.
• RoHS Compliant

• Color: As Desired, generally available in blue color.
• Dimensions: 60 cm X 60 cm.
• Chemical Composition: Carbon ferrite impregnated polyurethane foam
• Maximum service temperature: 90 degree Centigrade
• Power handling capacity: 0.5 Watt/in2 (Under forced air cooling) And 0.15 Watt/in2 (In normal air conditioned room)
• Fire Retardency: Passes NRL-8093, test 1, 2 & 3 With Zero Halogen Means.
• Our foam absorbers are fire retardant with zero halogen means thereby avoid formation of toxic gases like HCl/HBr and poisonous gases like phosgene.

• Broadband absorbers suitable for in-door measurements.
• Used in making microwave anechoic chambers for performing measurements like RCS, Antenna Measurements etc.
• Used in making Moving screens for hiding the areas of maximum reflections.
• Used for obtaining Quiet Zones in very wide frequency range.
