Our AF Series broadband foam RF absorber consists of lightweight, carbon-loaded polyurethane designed for broadband suppression of unwanted RF energy across 1.0 to 40.0 GHz. These materials provide wideband performance in a simple, economical format and are ideal for large-area coverage, cavity lining, or free-space applications where weight and cost efficiency are critical.

Compared with narrowband, tuned absorbers, the AF Series delivers broad-spectrum attenuation in a single material choice. Standard thicknesses can be tailored to optimize performance in the desired frequency band, and custom geometries or cut parts are available to simplify integration.
