Absorbers

AP-FLYER is an official partner of Company DMAS (Dutch Microwave Absorber Solutions) in Poland (www.dmas.eu; www.comtestnl.com), producer of polystyrene absorbers for EMC and microwave test facilities. All our absorbers are high performance polystyrene microwave absorbers suited for all anechoic chambers. The product range includes both hybrid (EMC) and microwave (broadband) absorbers.The unique selling point of the closed cell polystyrene absorbers is the absence of poisonous fire retardant chemicals. These absorbers are sustainable and 100% environmentally friendly. As a result the absorbers are fully compliant with REACH and ROHS.

 

The benefits of the microwave absorbers are:

  • Unique and enhanced product design
  • Alternating taper design (vertical – horizontal) resulting in improved reflectivity performance.
  • Light weight
  • Removable tapers
  • Compliant with clean room spec. class 10.000 / ISO14644-1 class 4
  • Uniform carbon cell loading results in a more stable performance.
  • Rigidity and superior tensile strength (no drooping tips)
  • Superior product life time (>40 years)
  • Resilience to humidity.

Hybrid absorbers for EMC test facilities

The hybrid polystyrene absorber range is designed for typical chamber solutions such as 3, 5 and 10m semi or full anechoic chambers, compact rooms and automotive test chambers. The hybrid absorber is a high performance, ultra wide band, carbon loaded polystyrene absorber with an operating frequency from 26MHz to 40GHz. The HT hybrid absorbers are tuned for perfect performance over ferrite tiles in EMC test facilities.

The HT series comprises three different models:

  • HT25 (10”)
  • HT45 (18”)
  • HT65 (26”)

All absorbers consist of a single base plate and separate tapers. The absorber base dimensions are 1200*600mm.

Upon customer request the hybrid absorbers can be equipped with white end caps.

Field Uniformity (FU) test floor set up

The HT45 absorber is also suited for field uniformity floor set up configurations according to the IEC/EN-61000-4-3 standard in (semi) anechoic chambers used for EMC testing. To protect the absorber tips whilst stacking the HT45 they can be equipped with a grey end cap (ECT45-G).

Wideband Ferrite Floor Absorber model FP-660.

The wideband ferrite floor absorber model FP-660 is designed to facilitate the use of all semi anechoic chambers for full compliance immunity testing in accordance to European Standards like IEC/EN-61000-4-3. In combination with the hybrid absorber model HT45 the FP-660 is perfectly suited for a floor setup for Field Uniformity (FU) testing according to IEC/EN-61000-4-3.

Hybrid Ferrite Tile model FT-106

The EMC hybrid ferrite tile FT106 is a sintered ferrite tile and delivers excellent electromagnetic absorption performance from 26MHz ~1GHz. Due to thin design of ferrite tiles the total volume of absorbers installed in a (semi) anechoic chamber is greatly reduced. The FT106 can be directly glued to the shielding enclosure or screwed to an inner structure which enables easy installation. The FT106 is also suited for hybrid (cascade) solutions in combination with the EMC hybrid polystyrene absorbers (HT series).

Microwave absorbers for antenna test chamber applications

The MT microwave absorber range consist of high performance, broad band, carbon loaded polystyrene absorbers with an operating frequency from 70MHz to 110GHz. Due to the excellent performance at microwave frequencies the MT series is designed for Antenna Pattern Measurement (APM), Compact Antenna Test Range (CATR) Radar Cross Section (RCS), Free space testing and Electronic Warfare (EW) anechoic chamber applications.

The MT series comprises three different models:

  • MT25 (10”)
  • MT45 (18”)
  • MT65 (26”)

All absorbers consist of a single base plate and separate tapers. The absorber base dimensions are 1200*600mm. Upon customer request the microwave absorbers can be equipped with white end caps.
