RFID frequency-specific absorber shielding
RADIO FREQUENCY INTERFERENCE ABSORBERS

Radiowaves emanating from electronic components such as the printed circuit board sketch at the right are addressed in three ways: sometimes no shielding is required; a reflective shield in the form of a local cover for the components, or the entire electronic enclosure can be fitted up as a shield; an absorber pad shield which soaks up the RF and converts it to imperceptible heat energy.

The latter Absorber Shield method deals with the unwanted radiowave energy right at the source and prevents re-radiation and reflection of the signals so that neighboring components are unaffected and higher order harmonics are reduced.

RFID SHIELDING PATCHES®

FOR PCB COMPONENTS AND WIRE CIRCUITS. A quick and easy way to gain 1 to 2 dB without invasive circuit changes. The EA3200H RF absorber matrix provides a measurable effect from 10MHz to 6.0GHz depending on frequency, existing circuit load, and area covered by the patch®. Peak performance is from 3.2GHz to 6.0GHz. Installs simply by removing protective adhesive liner. Convenient 6.00” x 8.00” 152 x 203mm sheets with (24) patches per sheet.
