EMI / RFHigh 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.
PLEASE NOTE – MINIMUM ORDER VALUE OF £ 9,000 GBP or $10,000 USD APPLIES TO ALL ABSORBER ENQUIRIES.
Long Hollow Absorbers
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 a 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.
Base Dimensions: Base dimensions: GDS-CAH1300 – 334 x 334mm, GDS-CAH1600 – 400 x 400mm, GDS-CAH2000 – 500 x 500mm, GDS-CAH2400 – 600 x 600mm.
Compatible Chamber: SAC-10m-C-LP (10m CISPR16-1-4 compliant).
