Thin and Flexible Microwave Absorber Suppresses Radiation Noise up to 36 GHz

Withwave, a designer and developer of a broad range of RF & MW Test Solutions and subsystems, has released a new microwave absorber that can suppress signals up to 36 GHz. The W−Absorber is a thin and flexible sheet made of a mixture of polymer resin and metal magnetic powder that can easily be bonded. This absorber can suppress radiation noise of electronic devices for wideband microwave frequency range and reduce surface current as well as surface reflection in cavity resonant application. The absorber can be used for frequencies up to 36 GHz (multiple options available) and is meant for markets including Commercial Communications, Security and Defenses, Automotive, General Electronics, Antenna Chambers etc.

Applications of the W-Absorber
  • It can suppress radiation noise of electronic devices for wideband radio frequency range and is effective in reducing surface current as well as surface reflection in cavity resonant applications due to the high magnetic loss characteristics of materials.
  • It can suppress reflection inside microwave modules and can be used to reduce cavity resonance of the module.
  • It is particularly suitable for use in masts of ships and walls to reduce reflections and echoes to nearby antennas and to reduce overall radar signatures by attaching to vehicles.
Availability
  • Standard sheet size S1 (105 x 150 mm), S2 (150 x 210 mm), S3 (210 x 300 mm: A4 Size)
  • W−Absorber can be used in different sizes, thicknesses and custom configurations on request
  • Thickness depends on the desired resonant frequency, and other resonant frequencies are available according to special request
