Convoluted Microwave Absorber

DMC Convoluted absorbers are made of flexible PU foam material block with the front surface cut to convoluted shape, dipped into absorbing slurry to provide desired electrical grading due to rounded convolutions and lacking sharp corners and points. Our CVT series absorbers are preferred for millimeter wave frequencies and for very wide incident angles.

  • Frequency range 8GHz to 80GHz
  • Typical reflectivity as high as -30dB
  • Fire Retardant per NRL-8093 1,2,3, with Zero Halogen
  • Continuous working temperature up-to 90°C
  • RoHS Compliant
  • Zero Carbon dust

Part number reference:
DMC-CVT-50, DMC-CVT-100
