Wide-Band Hybrid Pyramid EM Absorbers

Wide-Band Hybrid Pyramid EM Absorbers

Wide-Band Hybrid Pyramid EM Absorbers

For the construction of a small anechoic chamber, to get a larger space than one could build with pyramid-shaped absorbers. Performs very well in wide band (30 MHz to 18 GHz).

3630 Wide-band hybrid pyramid EM absorbers

The 3630 series Wide-band hybrid pyramid EM absorber is an 80 mm high absorber that measures 100 mm x 100 mm. It has good absorption performance in the wide band between 30 MHz and 18 GHz when combined with 6.3 mm thick Ferrite absorber tiles (Part # 3600-63).

The hybrid pyramid absorber is made out of a carbon-loaded polystyrene and is tuned for perfect performance over Ferrite absorber tiles.

Due to this special characteristic, the product is suitable for building a small anechoic chamber to get a bigger space than built with foam pyramidal absorber. It can also increase the frequency from 1 GHz to 18 GHz as compared to a standard anechoic chamber that only has Ferrite absorber tiles.

  • Performs very well in wide band (30MHz to 18GHz)
  • Small size (100 x 100 x 80 mm)
  • Long service life
  • Only 8 cm high, so room space can be used efficiently
  • So strong that an adult can stand on it
  • Does not deteriorate even if it gets wet
  • 10 times more durable than conventional products
  • By slant molding, stable quality is assured
  • Easy to install on wall surfaces without adhesives being required
