CobaltFx FET-WR05 Tx Extenders

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

  • Frequency Range: 150-220 GHz
  • Connector Type: Waveguide WR05
  • Each frequency extender module includes a Proxi-Flange™

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

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.

This frequency extender can be used to measure one-path transmission (S21 or S12) through the DUT when paired with a compatible receiver.

The system can be used for a variety of applications including antenna range measurements, material characterization, wafer s-parameter measurements, automotive radar & sensor testing, etc.


If you want to consult with our engineers about your specific application, please Ask an Engineer.

Every CMT VNA includes an RF measurement module and software application which runs on a Windows PC, laptop, or tablet, connecting to the measurement hardware via USB interface. Software can be installed on multiple computers that share the use of the analyzer measurement module. Test Automation programming in LabView, Python, MATLAB, .NET, etc.
