RF Foam series can be made in a variety of thicknesses to cover the microwave frequency range.
Thicker foam performs at lower frequencies.
RF Foam can be optimized for reflection loss or insertion loss. RFML - Multilayer foam made up of 3 RFLS layers. This graded approach gives a good broadband absorption over a wide frequency range. It provides the optimum in broadband performance and at the lowest weight. RFWP - Weatherproof versions of all the foams are available.
