EMI Suppression

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
Lower Q-factor (Q damping)
Reduce resonant fields inside enclosures
Improve shielding where metal alone falls short

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
Supplementing metal shielding solutions where resonance persists
Discrete frequency absorption for specific interference sources
Managing enclosure leakage paths at connectors, seams, and apertures

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
Reduce trace-level radiation
Prevent coupling to chassis and enclosure structures

PSA Options Available — Pressure-sensitive adhesive options allow direct placement without mechanical mounting hardware, simplifying integration into existing PCB assemblies.

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.
