Series

High power handling microporous pyramid absorbers can support inside and outside ventilation circulation, which would further improve the power handling capacity of such absorbers; it is mainly applied in high power shield cabinet, ventilation vents of anechoic chambers, and etc.

Reflection loss under vertical incidence (-dB @ GHz)

3690 - High power handling pyramid absorbers

Characteristics
  • Good flame retardant characteristics, it won’t burn when it encounters fire, it has oxygen index ≥ 60% and flame retardant B1 level.
  • Good power handling property, power handling under forced air cooling (continuous wave) can  be up to 8-10kW/m2.
  • It uses keel mounting method, without any adhesive.
