Tuned Frequency Absorbers (MR11 Series)
Targeted Attenuation at Specific Frequencies.
Without the Broadband Loss.
TUNED FREQUENCY ABSORBERS
MAST Technologies’ MR11 Series absorbers are engineered to provide targeted attenuation at specific frequencies of concern — used where narrowband interference must be mitigated without introducing unnecessary broadband loss across the surrounding spectrum.

Frequency-Specific RF Absorbers for Targeted EMI Mitigation
When the Problem Is a Specific Frequency — Not the Whole Spectrum.
MR11 absorbers are formulated to address narrowband EMI challenges without altering overall system architecture or imposing broadband loss on the surrounding frequency content.
Commonly applied within electronic enclosures and assemblies where predictable, frequency-targeted performance is required.
COMMON APPLICATIONS
MR11 Series
Tuned Frequency Absorption
Targeted Absorption — Without Touching the Surrounding Bands.
Tuned frequency absorbers are formulated to absorb RF energy within defined frequency ranges. By tuning absorber characteristics to the target signal, these materials help suppress specific interference mechanisms while minimizing impact on surrounding frequencies.
This approach lets engineers address narrowband EMI challenges without altering overall system architecture — no rework of nearby filter chains, no broadband loss imposed on signals that don’t need attenuating, no compromise to surrounding RF performance.
Performance & Test Methods
