WAVASORB® HFX / HFS

High-Power Broadband Hollow Pyramidal Absorber

WAVASORB® HFX / HFS is a high-power broadband absorber series featuring hollow pyramidal elements specifically engineered for medium- and high-power RF environments. The hollow design significantly reduces weight while enhancing natural air convection, supporting improved thermal performance under continuous wave exposure.

Each absorber geometry is individually optimized to deliver premium electromagnetic absorption performance across a wide frequency range from 80 MHz up to 40 GHz. Designed and quality-controlled using advanced simulation and test techniques, WAVASORB® HFX / HFS ensures reliable and repeatable performance in demanding measurement facilities.
