Elastomeric Absorbers
Often, when radio frequency sources are located inside a shielded cavity, the RF energy can resonate within the cavity, and interfere with the signal or create crosstalk with other adjacent elements. Microwave absorbers can be strategically placed within the cavity or housing to attenuate resonances and eliminate crosstalk. Broadband, magnetic RF absorbers such as C-RAM, RGDS, GDX or GDSS can be used for this purpose. C-RAM FLX is a tuned narrowband resonant absorber which can be ordered with the resonance specified anywhere between 0.8 to 35GHz. Magnetic absorbers are not electrically conductive, and can be placed directly over circuits without creating shorts.
Cuming Microwave supplies elastomeric RF absorbers in standard sheet form, and custom configurations. Microwave absorber materials are often supplied with a pressure-sensitive adhesive backing (peel-and-stick), which works in most applications. However, in extreme conditions—elevated temperature, vibrations, etc, we recommend more durable adhesives for attachment. These materials are offered in different binder and filler options, depending on application and frequency of operation.
