HYBRID PYRAMIDAL ABSORBER HYFRAL HY

Siepel

Michael Faradays Heritage

Suitable for EMC anechoic chambers

Broadband frequency range 30 MHz -40 GHz

20 years guaranteed performances

Unique plastic paint for pyramidal foam absorbers

Innovative and flexible installation system forferrite panels

Can be installed to upgrade existing shielded rooms

fhe key point of the HYFRAL HY hybrid absorbers design is the impedance matching between

FE30Z provide optimized reflectivity performances in the frequency range 30 MHz - 1 GHz *, and in order to extend the performances up to 40 GHz, an immediate and simple idea would be to glue a regular pyramidal absorber on top of the ferrite. However, some care should be taken so that the pyramidal absorber doesn't "hide" the ferrite. In other words the pyramidal absorber must be "transparent" enough to low frequency waves, so

special matched pyramidal absorber, impregnated with a specially formulated carbon solution (different from regular pyramidal absorbers HYFRAL APM). his allows to make the combination ferrite + matched pyramidal absorber highly performing

Consequently, the broadband performances of HYFRAL HY absorbers make them Ideal for use In EMC anechoic chambers to meet the specifications of the commercial EMI standards (such as CISPR 16-1-4 Ed 2, EN 50147-2, EN 55022, ANSI C63.4 and other similar standards) and EMS

GUARANTEED PERFORMANCES

guaranteed values, for 20 years. These values are the fruit of a long experience In electromagnetic absorbers manufacturing. Our absorbers reflectivity performances are checked In our factory, using cutting edge broadband equipment (14 m long coaxial line 1.83 x 1.83 m section, optimised designed fully anechoic chamber, Vector Network Analyzers). On top of that, we propose the customer to attend the reflectivity measurements in our factory with SIEPEL engineers.
