Eccosorb® FGM
Thin, Flexible, Broadband Microwave Absorber
THIN FLEXIBLE BROADBAND ABSORBER
Eccosorb FGM is a thin, flexible, magnetically loaded, silicone absorber. Silicone absorbers
have high service temperature capabilities and offer advantages for high power and low out-
gassing applications. They can be subjected to high altitudes, including space, with no adverse
effects.
FEATURES AND BENEFITS
• High power performance
• High magnetic loss
• Low outgassing properties
MARKETS
• Commercial Telecom
• Security and Defense

APPLICATIONS
• Eccosorb FGM is used to line cavities in which antennas operate. It may be applied to
surfaces to improve radar performance, reduce radar cross section or backscattering.
• Eccosorb FGM is effective even at high power in reducing specular reflections as well as
surface currents due to the high magnetic loss properties.
• When bonded to a metal surface Eccosorb FGM will significantly reduce the reflectivity of
metal objects or structures due to the flow of microwave currents on that surface.
• It can be applied to antenna elements, microwave dishes, the inner or outer surfaces of
waveguides for isolation, attenuation or modification of radiating patterns.
• Applications include power amplifiers, oscillators, down/up converters and LNB’s. It is also
utilized to modify antenna patterns, cover antenna feed supports, line antenna caps to
reduce reflections and improve the isolation of sensitive RF devices.
