SIEPEL Absorber High Power Absorber AHP

AHP absorbers are designed to line specific areas subject to high power densities (up to 20 kW/m² CW and above), in applications such as Telecom / Wireless, Satellite, Automotive, Military, etc...

Thanks to their specific open structure, they can withstand high temperatures resulting from generation of high fields strengths. AHP absorbers are typically used to line “hot spots” in anechoic chambers, where energy will be highly concentrated.

AHP absorbers are manufactured from honeycomb matrix, made from phenolic-based material. These whole blocks are entirely coated with carbon-based solution, creating their electromagnetic waves absorption properties, while their hollow open structure ensures a passive airflow cooling. For highly demanding applications, with power densities exceeding 20 kW/m² CW, forced air can be drawn through the AHP absorbers to extend their power withstanding capabilities.
