Absorbers

Suppressing Electromagnetic Noise and Enhancing RF Performance Without Mechanical Obstruction

Electromagnetic absorbers from Laird Performance Materials are advanced materials designed to soak up radio waves and high-frequency interference, converting them into negligible heat energy. These solutions are essential when traditional shielding is insufficient or when internal wave reflections within an enclosure degrade system performance. Laird’s Eccosorb™ and CoolZorb™ families are recognized as the global standard for solving complex EMC challenges.

Why Use RF Absorbers?

Absorbers provide solutions in scenarios where conductive gaskets are not applicable:

• Reflection Reduction: Preventing the “echoing” of radio waves inside metal enclosures, which can interfere with sensitive component operation.
• Antenna Performance Enhancement: Reducing Side Lobes and improving the accuracy and gain of antennas and radar systems.
• Crosstalk Reduction (Component Isolation): Preventing interference between adjacent components on the same PCB without the need for heavy metal shields or “cans.”
• Hybrid Solutions (Thermal + EMI): Laird’s CoolZorb series provides both thermal conductivity and electromagnetic absorption in a single product, saving valuable space in compact enclosure designs.

Selected Solutions from Laird

At Wave Components, we offer a wide variety of absorbers tailored to different frequency ranges:

• Eccosorb™ (Wave Absorbers): Materials based on rubber, silicone, or foam, optimized for absorbing frequencies from 100 MHz to 100 GHz (Millimeter Wave / mmWave).
• Q-Zorb™: Ultra-thin absorbers with high magnetic Permeability, ideal for direct application on enclosures or communication components.
• Flexible Absorbers: Sheets that can be precision-cut into complex shapes and adhered to concave surfaces or corners within the chassis.

The Wave Components Advantage in Absorption Solutions

Selecting the right absorber is an engineering task that requires a deep understanding of frequencies and materials:

1. Frequency-Specific Characterization: We assist in choosing the correct absorber type (Dielectric or Magnetic) based on the specific interference frequency of your project.
2. Custom Die-Cutting: Providing absorber sheets precision-cut to your CAD drawings, featuring integrated PSA (Pressure Sensitive Adhesive) for rapid application.
3. Integrated Solutions: The ability to combine RF absorbers with Thermal Interface Materials (TIM) to provide your system with dual protection in minimum volume.
