This material is similar to the standard High Performance Broadband Pyramidal RF Absorber but the tips are removed to provide a truncated version. The truncated shape reduces overall depth of the absorber, saving space in chambers and tip breakage is eliminated providing a more rugged product.
The truncated pyramidal RF absorber was developed specifically for low frequency applications in particular for designing EMC test chambers for emissions and immunity testing to industrial and military specifications. Reflectivity an physical characteristics:
Weight | Absorber Depth | Reflectivity (MHz) | ||||
(kg/m2) | (mm) | 80 | 250 | 500 | 1000 | 10,000 |
7.5 | 500 | -8dB | -22dB | -35dB | -38dB | <-40dB |
10 | 700 | -15dB | -27dB | -27dB | -40dB | <-40dB |
A combination of both material sizes installed in an appropriate sized chamber will provide an EMC test facility for full compliance immunity testing to EN 61000-4-3 and pre-compliance emissions testing.
The RF absorber is normally spray finished with a coat of light blue paint. Other colours are available on request.
The absorber is treated to provide a finished product, which meet the fire retardant requirements of NRL specification 8093 tests 1,2 and 3, MS-8-21 tests 1,2 and 3 and other International specifications.
