RF - Filters
  • RF-Filters and Coupler

    We design and manufacture custom specific filters and directional couplers according to your specifications, even in small quantities. We simulate with most modern software tools and manufacturing is done with most modern equipment. Test benches with calibrated network analyzers are available in house.

    We are working with high sophisticated software tools and most modern calibrated networkanalyzers from Rohde & Schwarz (ZVR) und Anritsu Wiltron. The manufacturing of our filter and coupler products is done on our CNC-equipment.

We can qualify our filters acc. specific environmental requirements, i.e. MIL, ETS und ESA (shock, vibration, temperature, vacuum, etc.). We have our own vacuum chamber. For the manufacturing of our VHF/UHF/SHF filters we are using materials like titanium, aluminium, stainless steel, invar and microwave proof plastics. Surface treatment can be done acc. all common standards. e. g. silver- or goldplating.
