BandSorb® FB is a lightweight high loss carbon impregnated dielectric foam absorber.
BandSorb® FB provides a very low cost solution for many applications over the thinner more expensive rubber absorbers.
BandSorb® FB can be used for applications requiring absorption across a wide range of frequencies , such as antenna cross-talk, side lobe reduction and cavity resonance suppression.
Availability:
BandSorb® FB series materials can be supplied in sheets as well as custom configurations. The standard sheet size is 610 mm x 610 mm. The BandSorb® FB consists out of carbon loaded polyurethane foam. BandSorb® FB is electrically conductive due to the use of the carbon dispersion.
Features and Benefits:
Lightweight, flexible and easy to trim, High Loss, low density.
Available in different thicknesses to work in a wide range of broadband frequencies.
Applications:
BandSorb® FB series can be used to
- lower cavity Q’s in RF amplifiers, oscillators, cabinets containing microwave devices, computer housings, LNB’s.
- isolation of antennas by Insertion loss, shrouding antennas to improve the antenna patterns and undesired back lobes
- reduce surface currents on radiating elements and outer ground-plane type surfaces.
- Reflectivity of an object (metal or otherwise) can be reduced somewhat by applying one or more layers.
