CobaltFx cost-effective millimeter wave frequency extension system allows you to build a scalable and affordable 5G testing solution. The system can be anchored by your choice of four vector network analyzers with 2- and 4-port options. The system comes with all necessary standard length cables and waveguide calibration kits. 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.
