SHF absorbing materials are carbonyl iron powders and silicone rubber composite materials. They are superior high frequency absorbing materials for high temperature applications. They can work at 180°C for a long time, and can work up to 220°C for short periods.
SHF absorbing material product structure has three layers: Absorber, adhesive and liner.
Features:
– High temperature resistant
– 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 devices and equipment shielding boxes
– Microwave integrated amplifiers
– Frequency mixers
