Cavity Elastomer Absorbers

ABS-HLE / HLSE

ABS-HLE is a polyurethane elastomeric absorber with a standard thickness of 0,5mm, the material is highly magnetically loaded and electrically non conductive. Although the material is highly magnetically loaded the material remains flexible and easy to apply in the application. The absorber material is designed to perform in the frequency range above 4 GHz. It concerns a broadband microwave absorber which is often applied in cavity resonance applications and to suppress surface currents in the microwave frequency range.

ABS-HLSE is the silicone version of ABS-HLE, the silicone version is typically used on space applications where low outgassing is required. The silicone version has higher operating temperature which is applicable on high power applications. Also as the silicone is more impervious to outdoor weather conditions, we recommend to use the silicone material for outdoor exposure applications.

Applications

  • Lower the Q-factor in cavities
  • Improvement of antenna patterns
  • Microwave converters, amplifiers, duplexers
  • Antennas and RF modules in space applications

ABS-SCE / SCSE

ABS-SCE is a polyurethane elastomeric absorber with a standard thickness of 0,75mm, the material is magnetically loaded and electrically non conductive. The absorber material is designed to perform in the frequency range starting in X-band and above. It concerns a broadband microwave absorber which is able to lower the Q-factor in RF cavities and to suppress surface currents in the microwave frequency range. Due to its moderate thickness and specific magnetic filler the material is easy to cut and install on complex shaped surfaces.

ABS-SCSE is the silicone version of ABS-SCE, the silicone version is typically used on space applications where low outgassing is required. The silicone version has higher operating temperature which is applicable on high power applications. Also as the silicone is more impervious to outdoor weather conditions, we recommend to use the silicone material for outdoor exposure applications.

Applications

  • Lower the Q-factor in cavities
  • Improvement of antenna patterns
  • High frequency sensors (automotive and other safety applications)
  • Microwave converters, amplifiers, duplexers
  • Antennas and RF modules in space applications

ABS-LFE / LFSE

ABS-LFE is a polyurethane elastomeric absorber with a standard thickness of 0,5mm and 1mm. With its specific magnetic filler system the material is developed for the lower frequency range, typically from 800 MHz up to 12 GHz. Although the material is highly magnetically loaded the material remains flexible and easy to apply in the application.

ABS-LFSE is the silicone version and is typically used on space applications where low outgassing is required. The silicone version also withstands high temperature on high power applications. Typical frequency of operation is 4 GHz and above.

Applications

  • Improve reflection from metal surfaces
  • Isolation of microwave waveguide cavities in amplifiers and radio’s
  • Improvement of patch antenna patterns
  • Antennas and RF modules in space applications
  • Antennas and RF modules in space applications
