Tuned Frequency Absorbers
Description
Tuned or Resonant Frequency Microwave (RF) Absorbers are a thin magnetically loaded sheet stock. Tuned Frequency Absorbers provide great reflection loss at a discrete frequency, typically offering 20dB of attenuation. Tuned Frequency Absorbers offer a narrowband of absorption, typically +/-10% of the resonant frequency, so are best used when a single discrete frequency is trying to be absorbed. Limitless Shielding can tune an absorber to any frequency from 1 to 40 GHz, by simply changing the formulation and thickness.
Applications
- Ship masts
- Specular return (RCS)
- Discrete frequency absorption
- Antenna isolation and patterning
- Aircraft seals
- Aircraft ducts
- Instrument housings
Features and Benefits
- Tough material can survive outdoor exposure
- Very thin for compact locations
- Flexible elastomeric material will not crack
- Support broad frequency range
- RoHS Compliant
- Halogen Free

Ordering Information
This materal is available in 305 x 305mm (12″ x 12″) and 610 x 610mm (24″ x 24″) sheets. However we can cut the sheets to shape and size as per your requirements. To indicate a required sheet size please add the suffix “-305” or “-610” accordingly.
It is available with and without PSA. If you require PSA please add the suffix “-PSA” to the required part number. For example for 3.3mm thick 610mm sheet Tuned Frequency Absorber IN Silicone with PSA the part number would be “MA-TFS-2-610-PSA”.
