Reduce EMI and Improve Signal Integrity in High-Frequency Systems
As systems become smaller and operate at higher frequencies, EMI, cavity resonance, and signalleakage become critical risks. MAST absorber materials are engineered to suppress interference at thesource—helping maintain stable performance in high-frequency environments.

EMI Suppression Solution
Suppress Interference at the Source. Protect Performance at Every Frequency.
As frequencies increase and systems become more compact, EMI, cavity resonance, and signal leakage become critical risks. MAST absorber materials are engineered to suppress interference at its source—helping maintain stable, high-frequency performance across 1–40 GHz environments.

Optimized Absorber Solutions for EMI Suppression
Three Proven Approachesto EMI Control
Cavity Resonance Control
Cavity Resonance Absorbers
Reduce resonant peaks and lower Q-factor inside enclosures—restoring shielding effectiveness without redesigning the system.
ENGINEERED TO
Frequency-Tuned Mitigation
EMI Emissions Management
Target interference at specific frequencies to reduce emissions without impacting overall system performance.
MAST absorbers are tunable across 1–77 GHz, allowing precise mitigation of discreteinterference sources without broad-spectrum overcorrection.
APPLICATIONS INCLUDE
PCB-Level Suppression
Surface Wave Absorbersfor PCB Traces
Reduce radiated emissions and prevent field coupling at the trace level—improving signal integrity in high-density PCB designs.
DESIGNED TO
PSA Options Available — Pressure-sensitive adhesive options allow direct placement without mechanical mounting hardware, simplifying integration into existing PCB assemblies.
Work With MAST Technologies
Cleaner Signals.
Better Shielding.
Faster Time to Compliance.
MAST absorber solutions reduce resonance, emissions, and leakage paths—helping engineers achieve stable RF performance and faster EMI compliance.
Whether you’re resolving EMC issues, optimizing an enclosure, or integrating absorber materials into an existing design, our engineering team works with you to select and validate the right solution.
WHY ENGINEERS CHOOSE MAST FOR EMI
Source-Level Suppression
Absorbers target the interference at its origin — cavity, trace, or aperture — rather than managing symptoms downstream.
Tunable to Your Frequency
Materials tunable from 1–40 GHz for targeted absorption at your specific problem frequency — not broad-spectrum guesswork.
Drop-In Integration
PSA-backed options work directly over PCB traces and inside enclosures — no hardware changes, no redesign required.
In-House Testing & Data
Every material ships with verified test data from our AS9100D-certified lab — VNA measurements, resistivity, and lot traceability.
