High Power Hollow Pyramidal Absorber

HIGH PERFORMANCE RF ABSORBER FOR MEDIUM HIGH POWER

C-RAM HPA (390-11) DOWNLOAD TECH SHEET PDF
C-RAM HPA is a hollow pyramidal RF absorber designed to provide high levels of absorption in high power applications. Typical uses include the hot spots in test rooms or anechoic chambers where heating due to concentrated power might damage conventional materials or lead to danger of smoke and fire. Power densities of up to 2 W/in2 have been handled successfully. C-RAM HPA is usually used with other products such as C-RAM SFC or C-RAM EVA in an anechoic chamber application.

      C-RAM HPA consists of lightweight, hollow pyramids. The pyramids are formed by folding relatively thin sheets of lossy foam plastic into shape and bonding them to a foam back panel. As an option, small vent holes may be bored through the walls of the absorber, allowing forced cooling air to be blown through the piece from behind.
