Introduction
The compatibility of electronic devices with various electromagnetic environment has become an important issue
in recent years.
AMIC have developed the EX-series Absorbers, manufactured based on our technologies and know-how
accumulated. They have reduce the weight and flexibility. Much absorption loss provides you with many
applications in EMI/EMC field such as mobile phones, LCD cables, military applications and the SAR issues.
Applications
 Suppressing radiated noise and its internal interference of electronic devices.
 Intra-system application to suppress noise in quasi-microwave range.
 Improving the distance of electromagnetic signal recognition and preventing interference between loop
antennas and adjacent metal objects.
 Communication
devices, office electronics, computer, home appliances, and devices mounted on automobiles,
radar’s and TV ghost measures, ETC (the electronic toll collection system), wireless equipment, military, etc.
Features


Excellent electromagnetic absorption performance in the microwave ranges.
Thin, lightweight, flexible; reliable to apply in wide applications.
High permeability which realize excellent performance in noise suppression.
The application frequency range; quasi-microwave band, C(4~8GHz), X(8~12GHz), Ka, K band.
High electrical resistance.
Various shapes and sizes are available on requests.
Effects
Concept of RF Absorber
EX-Series absorbers are absorbing the energy of electromagnetic noises and to transfer them into heat.
