The MF22-0003-00 from MAST Technologies are Lossy Foam Absorbers that operate from 1 to 18 GHz. These RF absorbers are designed with a constant coating to exhibit high reflection loss and are intended to be applied to metal surfaces inside microwave cavities, housings, radomes, network enclosures, or antennas. The absorbers are 12.8 mm thick and are available in sheets that measure 24 x 24 x 0.2 inches. They are ideal for antenna pattern performance, EMI reduction, antenna isolation, and radar cross-section reduction applications.
