RF Cable Assemblies

Microwave and RF technologies are used across a broad range of applications, from complex networking products to high-end defence communication devices.

With over 30 years’ expertise, GTK offers a wide selection of products to meet any requirement for RF and custom coax cable assemblies and connectors. Our core range focuses on connectors with maximum frequencies ranging from 4 GHz to 40 GHz, and we are able to supply products suitable for any frequency up to 110 GHz.

As with all of GTK's products, the quality of our microwave and RF cable assemblies is of the highest priority to us. We go to great lengths to ensure that our production and testing standards are second to none, resulting in an end product that is fit for purpose and designed to last.

Manufacturing Capabilities

As well as manufacturing RF and custom coax cable assemblies in the UK, we work with a leading RF specialist manufacturer in Taiwan who is at the forefront of RF research, with strong links to several higher education facilities.

  • High level of technical expertise for design and development
  • Manufacture of its own connectors, along with cable assemblies
  • Support with cable assemblies and connectors, allowing extra scope for customisation


With the support of our specialist partner, we test every production run for the bare minimum of:

  • 100% continuity checks
  • 100% short-circuit testing
  • 100% resistance checks
  • batch test of VSWR and insertion loss

We are also able to conduct performance tests of our custom RF cable assemblies to your exact specifications. To do this, we use a range of network analysers capable of testing the full frequency range from 300 kHz to 110 GHz. Full test reports can be provided as required.
