C-RAM FAC is a series of high performance broad banded microwave absorbers, made from light weight, flexible urethane foam treated with a dielectric lossy material. C-RAM FAC is fire retardant and meets NRL 8093.
C-RAM FAC is a convoluted product; the front face is rippled or convoluted like an egg carton. These convolutions provide an impedance taper, which is very effective in minimizing front face reflections, especially at higher frequencies. C-RAM FAC is the workhorse of the industry for frequency ranges of 15 GHz and above. For premium performance at lower frequencies the SFC product line is recommended.
C-RAM FAC is frequently used to line anechoic chambers used for high frequency measurements, and has many applications involving suppression of unwanted RF and radar reflections.
