Epoxy and Thermoplastic Absorbers

ABS-SRB


ABS-SRB is an epoxy based absorber material with high magnetic loss., as the absorber material is rigid it can be machined to specific shapes. Depending on frequencies and required losses different grades are produced each with their specific electrical RF-parameters. Standard supply formats are bars, rods and plates. To meet customer needs and requirements the material can also be supplied to specific three dimensional shapes. ABS-SRB is used in microwave applications as RF-loads, attenuators but also as surface current suppressor on antenna elements.

The absorber part can be bonded in place using an epoxy adhesive, if needed ABS Technics can assist to select an appropriate adhesive. In case of mechanical fixing we can supply the finished parts equipped with a thread to allow bolting in to the application.

Applications

  • Waveguide terminations
  • Coaxial terminations
  • Antenna elements
  • Satcom
  • LNB

ABS-STB


ABS-STB is a range of magnetically loaded thermoplastic materials, RF-properties are comparable to ABS-SRB. Lossy 3D shaped absorber parts find their application in high frequency microwave radio’s and Satcom systems. Many high volume applications such as microwave radio’s, satcom, broadcasting use magnetically loaded absorbers.

ABS-STB are thermoplastic absorbers which are developed to allow injection moulding as such we can produce in a cost effective manner 3D shaped parts in a high volume quantities. In addition to the typical use as RF-loads or surface current suppressors the material can also be used to produce absorber covers for installation and to protect area’s on printed circuit boards. When using ABS-STB as a cover the product has both functions, RF-absorber but also as shielding cap with a reasonable shielding level. ABS Technics produces ABS-STB in 2 different versions, a rigid version based on polypropylene and a flexible version based on thermoplastic elastomer.

Applications

  • Waveguide terminations
  • Absorber covers
  • Antenna elements
  • Satcom
  • LNB
