Welcome to DMC RF Shop, your trusted destination for high-performance RF absorbers, microwave absorbers, and electromagnetic interference control products. Whether you're designing anechoic chambers, shielding sensitive equipment, or testing high-frequency devices — our absorbers deliver optimal attenuation, reliability, and efficiency.
RF absorbers and microwave absorbers are engineered materials designed to absorb electromagnetic energy, reduce reflections, and minimize unwanted noise across radio frequency (RF) and microwave bands. These simple yet critical components form the backbone of testing accuracy in:
Our absorbers are available in various materials including carbon-loaded foam, ferrites, pyramidal panels, and broadband absorber tiles — crafted for precise performance from low MHz to high GHz frequency ranges.
We specialize in quality-tested products that deliver consistent performance:

RF and microwave absorbers are specialized materials designed to attenuate electromagnetic energy. They minimize reflections within testing environments like anechoic chambers, ensuring accurate measurements for antenna patterns, RCS, and EMC compliance.
Pyramidal absorbers provide the highest level of absorption by gradually transitioning the impedance from air to the absorber material. Wedge absorbers are designed to guide reflections in a specific direction and are often used in specific chamber areas or to reduce backscatter.
Our absorbers cover a wide spectrum, typically from low MHz ranges (e.g., 30 MHz with Hybrid absorbers) up to 40 GHz and beyond with high-frequency Millimeter Wave absorbers. The specific range depends on the material type and thickness.
Standard pyramidal absorbers are soft and not load-bearing. For areas requiring foot traffic, we offer Walkway Absorbers (like our DMC-PP-WW series) which are high-density and durable, designed specifically for floors in anechoic chambers.
Yes, safety is a priority. Our polyurethane foam absorbers are treated with fire-retardant chemicals to meet international safety standards such as NRL 8093 and UL 94, ensuring they are safe for use in testing facilities.
