ORBIT FR Hybrid Clean Room Absorbers - Manual (Page 2)

The hybrid clean room absorbers are coated in clear latex top and bottom for use in class
100,000 clean room environments. The overall performance is unaffected by this treatment. These
absorbers are used extensively in satellite assembly facilities as well as other aerospace
applications.
Ferrite Hybrid
Technology
Ferrite absorbers offer good performance from 30 MHz to 600
MHz, while traditional dielectric foam absorbers deliver perfor-
mance satisfaction above 500 MHz. The combination of the
two can yield precarious results if the selected materials have
mismatched impedance characteristics.
With proper impedance matching, these two materials can be
joined to create a hybrid absorber structure that benefits from
the inherent performance characteristics of each of the indivi-
dual materials. The AEPH series of EMC absorbers incorpo-
rates a urethane pyramidal absorber structure which can be
precision matched to any brand of tuned ferrite tile absorbers.
The resulting product delivers super-broadband reflectivity
performance from 20 MHz to 40 GHz!

Unique Manufacturing Process
After the standard manufacturing process, the absorbers
undergo a specific procedure to remove any loose debris
left from the manufacturing process, then are coated with
a special latex binder.
