The 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 continuous electrical coating to exhibit high insertion loss and are intended to be applied to surfaces inside microwave cavities, housings, radomes, network enclosures, or antennae. Lossy Foam Absorbers attenuate energy at normal and high angles of incidence at frequencies from 1 GHz to 18 GHz.

The primary method of application for Lossy Foam Absorbers is utilizing a Pressure Sensitive Adhesive (PSA) backing. CTS proudly uses 3M transfer tapes on it’s Lossy Foam Absorbers. Contact CTS technical representatives for a datasheet on the PSA. Other liquid and paste adhesive may be recommended. Contact a CTS technical representative for more information.
This performance plot illustrates the insertion loss performance of this material. Insertion loss is measured in a transmission tunnel, for more information on the transmission tunnel test set-up, please refer to Tech Bulletin 103. Additional electrical test data may be available upon request.
