CobaltFx FEV-12 Frequency Extension System, 60 to 90 GHz

Copper Mountain Technologies is announcing an End-of-Sale (EOS) for the FEV-12 Frequency Extenders. This product is no longer available for purchase as of April 13, 2023. We will provide service and repair for this instrument for a minimum of 3 years from the EOS date and based on parts availability afterwards.

CobaltFx cost-effective millimeter wave frequency extension system allows you to build a scalable and affordable 5G testing solution.

  • Frequency Range: 60-90 GHz
  • Connector Type: Waveguide WR12

The system can be anchored by your choice of four vector network analyzers:

Total cost of the system depends on selected VNA. The extenders are packaged in small and versatile enclosures that allow for flexible port arrangements. Waveguide ports are manufactured in accordance to the new IEEE 1785-2a standard and ensure industry best alignment and repeatability of connection, allowing for long interval times between calibration.
