Premium RF and Microwave Absorber Products

dB Absorber specializes in precision manufacturing of high performance broadband anechoic absorbers for RF and Microwave applications in a variety of configurations. Our singular focus on producing the highest quality material on the market means that we pay close attention to the quality of the manufacturing process as well as testing and certification requirements.

dB Absorber offers a full range of carbon loaded RF and microwave absorber products in flat sheet, pyramidal, wedge and convoluted surface configurations. They are most commonly used to cover electrically reflective structures in the path of RF energy to eliminate unwanted reflections. Applications include EMC measurements, antenna pattern measurements, radar applications and others.

dB Absorber material is constructed using a foundation open cell polyurethane foam volumetrically loaded with carbon and fire retardants to produce dielectric properties that are well suited for ultra-broadband performance. All absorbers meet NRL 8000 I,II and III requirements. The material comes in a range of depths and shapes appropriate for applications in lining anechoic chambers, coverage of conformal surfaces and specialized applications. Standard pyramidal material is supplied in various cone heights ranging from 2in to 36in with a tile size of 20in x 20in. Absorbers are available unpainted, painted in a variety of colors, or painted with a rubberized coating.

dB Absorber can be seamlessly integrated with absorbers made by other manufacturers to meet the needs of customers with existing infrastructure that needs to be repaired, expanded, or otherwise enhanced. While we specialize in the most commonly used profiles of pyramidal absorbers, we can also provide custom-designed products to meet customer specifications.
