MF2: Lossy Foam Absorbers

MAST Technologies’ Lossy Foam Absorber product series is a lightweight conductive carbon loaded sheet stock providing broadband insertion loss at microwave frequencies. Lossy Foam 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 antennae. Lossy Foam absorbers are the lowest cost solution for attenuating energy at frequencies from 1 GHz to 18 GHz.
