MAST Technologies MR21-0012-01

MAST Technologies MR21-0012-01 is a thin magnetically loaded sheet stock with loss at microwave frequencies while retaining the desirable properties of elastomeric binders. Cavity Resonance Absorbers are designed to have a high loss and are intended to be applied to metal surfaces inside microwave cavities to reduce the cavity's Q. Cavity Resonance Absorbers attenuate energy at normal and high angles of incidence at frequencies ranging from 1 GHz to 20 GHz. The most common elastomer is silicone, but other elastomer formulations are available.

Method of Application

The primary method of application for Cavity Resonance Ab-sorbers is utilizing a Pressure Sensitive Adhesive (PSA) backing. MAST proudly uses 3M transfer tapes on it’s Cavity Resonance Absorbers. Contact MAST technical representatives for a data-sheet on the PSA.
Other liquid and paste adhesive may be recommended. Con-tact a MAST technical representative for more information.
