Low Frequency Microwave (RF) Absorbers are a magnetically loaded sheet stock having high loss at sub-microwave frequencies. Low Frequency Absorbers are designed with shaped magnetic particles which exhibit high permeability at frequencies from 1 MHz to 3 GHz. The Low Frequency Absorber product line is the thinnest of the absorber products, with standard thicknesses of 0.006” and 0.020”; other thicknesses and configuration as available.

 Typical Applications

  • Traveling, creeping, surface wave absorption
  • Resonant Cavity Attenuation
  • EMI Reduction
  • Mounted to an IC on a PCB
  • Mounted directly on a microstrip
  • High Frequency Interference
  • Inside a shielding can
