Hybrid absorbers (HT series)

The HT hybrid absorber is a high performance, ultra wide band, carbon loaded polystyrene absorber with an operating frequency from 20 MHz to 40 GHz. The HT hybrid absorbers are tuned for perfect performance over ferrite tile FT106 in (semi) anechoic chamber applications.  The HT hybrid absorber series consist of three different models:

  • HT25 (250mm / 10”)
  • HT45 (450mm / 18”)
  • HT65 (650mm / 26”)

The base plate dimensions of DMAS absorbers is 1200*600mm. All absorbers have a modular design of separate base plates and tapers. Upon customer request the hybrid absorbers can be equipped with white end caps.

Microwave absorbers (MT series)

MT microwave absorbers are high performance, broad band, carbon loaded polystyrene absorbers with an operating frequency from 70 MHz to 40 GHz. Due to the excellent performance at microwave frequencies the MT series is suited for Antenna Pattern Measurement (APM), (compact) Antenna Test Range (ATR) and Radar Cross Section (RCS)  anechoic chamber applications.  The MT microwave absorber series consist of three different models:

  • MT25 (250mm / 10”)
  • MT45 (450mm / 18”)
  • MT65 (650mm / 26”)

The base plate dimensions of DMAS absorbers is 1200*600mm. All absorbers have a modular design of separate base plates and tapers.
