High PowerHigh Performance Absorbers
Global EMC provide a wide range of anechoic absorber for RF, EMC and microwave applications. Specifically designed to reduce or eliminate the reflections from electromagnetic waves by absorbing the energy, dissipating the waves and turning it into heat energy. Designed to cover a wide frequency range, our portfolio of anechoic absorbers range from microwave absorbers, through to high power and hybrid absorbers.

High Power Absorbers
Global EMC’s high-power handling pyramid absorbers (GDSxxx-HPP) are designed for use in anechoic chambers where high power density is required. Power handling capability of up to 10 kW/m² can be achieved using the GDSxxx-HPP range. This is comparable to a maximum of 1 kW/m² for the standard GDSxxx range and 3 kW/m² for the GDSxxx-RTH reticulated foam absorber range.
The absorbers can be installed in an anechoic chamber and on equipment within the chamber. This can be either full coverage or a carefully designed partial lining.
The absorbers hollow honeycomb construction allows heat to dissipate effectively from the absorber. This can be either using the natural circulation of air through the process of convection inside the anechoic chamber or by using forced air systems to dissipate the heat build-up.
The absorbers can be supplied in a 500mm x 500mm or a 600mm x 600mm base size to compliment the surrounding absorber base sizes in partially lined chamber installations.
