| C-RAM GDX (310-11) |   |
| C-RAM GDX is a thin, magnetically filled microwave absorber rubber sheet stock which has high loss at microwave frequencies from 1 to 18 GHz. It is applied to metal surfaces to attenuate RF surface currents. It can be used to modify antenna patterns, lower the Q of a cavity, act as a transmission line attenuator, and modify the radar cross section of targets.
C-RAM GDX is thin and elastomeric, so it will conform to curvatures of the substrate. It is not electrically conductive, and has high dielectric strength. It is a soft material and is readily die-cut or cut with a razor. Being based on a silicone rubber, it will withstand wide temperature ranges, and survive outdoor exposure. C-RAM GDX has a high magnetic loss tangent from 1 GHz to 18 GHz. Thicker grades are required to attenuate at lower frequencies to obtain the same performance as a thinner grade at higher frequencies. C-RAM GDX is available in silicone or urethane elastomers. Please refer to Technical Bulletin No. 310-1 for properties and benefits of each type of elastomer. |
