HF absorbing materials are carbonyl iron powders and rubber composite materials. They are high frequency absorbing materials designed for microwave frequency bands. They can suppress electromagnetic wave leakage caused by high frequency noise, and EMI inside circuits.
HF absorbing material product structure has three layers: Absorber sheet, double-sided adhesive and paper liner.
Features:
– Significant high frequency loss
– Fast attenuation speed
– Wide absorbing frequency range
– No signal distortion in the operating frequency range
– RoHS complaint and Halogen free
Applications:
– RCS reduction
– Radars
– Microwave integrated amplifiers
– Frequency mixers
– Satellite TV tuners
