Key Features

  • Numerically Optimized Design
  • 200 V/m Power Handling Capability
  • Fire Retardant
  • FlexSorb option available

ETS-Lindgren's Wedge Absorber effectively reduces reflections between 30 MHz and 100 GHz and its RF reflectivity levels are the same as its equivalent sized pyramid absorber. Wedge absorbers are used in areas of chambers where pyramid absorbers would provide too much backscatter under specific configurations.

ETS-Lindgren guarantees its EHP absorbent material meets specified standards for material fire retardancy. Wedge absorber can also be provided in transitional parts from one size to another providing a continuous line in the absorber, i.e. a 12.7 cm (5 in) wedge to a 31.1 cm (12.3 in) wedge. These parts are typically 61 cm x 121.9 cm (2 ft x 4 ft) or 61 cm x 182.9 cm (2 ft x 6 ft) long and used in tapered or compact range chambers.

Optional FlexSorb™ Treatment

With FlexSorb, you can enjoy the same excellent performance characteristics as our traditional absorbers, with the advantages of improved durability. FlexSorb is a special absorber treatment that allows an absorber to bend but not break. It's ideal for high traffic areas like chamber doorways and interior walls, or for tests that require an anechoic floor treatment. And, being that FlexSorb is also non-hygroscopic: its weight does not change in the presence of atmospheric moisture.
