Lossy Foam Absorbers

Lossy Foam Absorber product series is a lightweight conductive loaded sheet stock providing broadband insertion loss at microwave frequencies.

Lossy Foam Absorbers are designed with a constant coating to exhibit high insertion loss and are intended to be applied to metal surfaces inside microwave cavities, housings, radomes, network enclosures, or antennae.

Lossy Foam absorbers are the lowest cost solution for attenuating energy at frequencies from 1GHz to 18 GHz.

  • Carbon loaded sheet stock
  • Broadband insertion loss at microwave frequencies
  • High insertion loss
  • Application on metal surfaces
  • Attenuation of energy at frequencies from 1 GHz to 18 GHz
