microwave absorber pads

microwave absorbers

Microwaves 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 microwave

energy right at the source and prevents re-radiation and reflection of the

signals so that neighboring components are unaffected.

Reflective Shield

Typical shielding approach allows

reflected radiation to affect neighboring

components.

Absorber Shield

Noise absorber approach assimilates

radiated frequencies and converts to

imperceptible heat energy.

microwave absorber

up to 116 GHz: MA series

The MA series is a high frequency microwave noise absorber in a range

of formulations addressing 2.5GHz to 116GHz radiations from electronic

components. It has a multi-layered structure of screened coating matrixes

adjusted for discrete impedance matching to absorb microwaves from a

wide range of angles.
