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
Reflective Shield
Typical shielding approach allows
reflected radiation to affect neighboring
components.
Absorber Shield
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.
