CobaltFx FET1854 Frequency Extension System, 18 to 54 GHz

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

  • Frequency Range: 18-54 GHz
  • Connector Type: Coaxial NMD 1.85mm

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.
