Long Hollow Absorbers

Hollow pyramid broadband absorber for larger EMC CISPR16 compliant chambers.

Overview

The Global EMC ‘Hollow pyramid absorber’ is designed to give excellent return loss performance and compliance.

The GDS-CAH system has a rigid structure so that it does not deflect under its own weight even when 2 metres long.

This absorber system has true broadband performance from 30MHz to 18GHz+ and does not suffer the problems of employing two technologies: Magnetic permeability of Ferrite tiles versus Progressive Impedance of resistive pyramidal absorbers.

This multi-layered absorber system is unique to Global EMC and the resultant performance causes compliance to CISPR EMC emission standards and all IEC/EN 61000.4.3 EMC immunity standards.
