Absorber
Absorber
- AH-11: A silicone-based material filled with magnetic particles, designed for resonant frequency absorption in a narrow band. It operates within a frequency range of 1 to 40 GHz and offers an attenuation of less than -20dB (99% energy loss). The material is suitable for applications like antenna isolation and electromagnetic interference reduction.
- AH-21: Similar to AH-11 but focuses on cavity resonance attenuation. It operates from 1 to 20 GHz with an attenuation of less than -10dB (90% energy loss).
- AH-31: Designed for surface wave absorption, this material also targets cavity resonance attenuation. It operates within 1 to 20 GHz with similar attenuation properties as AH-21.
- AH-41: A high-loss cavity resonance absorber with a frequency range of 1 to 18 GHz. It is designed to reduce the Q index of cavities.
- AH-51: Made with an acrylic binder, this absorber targets low frequencies from 1MHz to 3GHz, with attenuation ranging from -3 to -10 dB.
- AH-91 to AH-94: These are foam-based materials filled with carbon, designed for wide-band resonance frequency absorption. They operate within 1 to 18 GHz and are used for applications like antenna pattern performance and electromagnetic interference reduction.
- Common applications across all types include automotive, aeronautics, military, shipbuilding, telecoms, antenna isolation, electromagnetic interference reduction, and radar wave absorption.
- Specific applications vary slightly depending on the absorber type, focusing on aspects like surface wave absorption, cavity resonance attenuation, and antenna pattern performance.
- All absorbers are silicone-based or foam-based, with varying thicknesses and dimensions tailored to specific frequency ranges.
- Operating temperatures generally range from -50°C to +190°C, with some variations depending on the material type.
- Most materials are grey or black, with compliance to UL and RoHS standards.
- Each absorber type has a specific part numbering system that indicates the presence of adhesive (PSA) and the thickness of the material.
