Wedge Absorbers

Global EMC’s wedge pyramid absorber gives excellent performance in compact chambers.

Overview

Wedge absorbers give around 20% more anechoic performance than full peak absorbers at frequencies below 1 GHz, due to their greater mass. The wedge system is used where a low frequency bias is required.

Using the 20% mass the Wedge absorber system can save money by using smaller pyramids.

The microwave performance is excellent with a return loss of -40dB at 8 x wavelength.

Global EMC’s wedge pyramid absorber gives excellent performance in compact chambers. The absorber fully complies with NRL 8093 parts I, II and III Fire safety standard.
