Semi-rigid cable assemblies for cryogenic applications

Paul Boughton

The Cable Assembly division of Intelliconnect (Europe) Ltd, the UK based specialist manufacturer of RF connectors, can now provide high performance semi rigid cable assemblies suitable for industrial, defence/security, and test system applications.

Standard semi-rigid cable assemblies are generally of copper construction, offer low loss, low VSWR performance, are phase stable and can be phase matched, allowing customers to specify the electrical length in time or degrees at the frequency of operation for a specific cable assembly. Phase matching of a cable assembly is essential when connecting to multi-channel receivers as individual channels are required to match and track each other over the frequency of operation.

Intelliconnect can also provide Cryogenic Semi Rigid cables for applications requiring operation at low temperatures including use in environmental test chambers. Intelliconnect Cryogenic Semi Rigid cables are made in a range of materials including stainless steel, cupro nickel and niobium/titanium superconducting cables. They are specified worldwide due to their low temperature performance, strong electromagnetic field and high thermal gradient below 4˚K.

Additional features include low thermal conductivity and high performance to 40GHz. The niobium/titanium cables offer very low heat conductivity, high durability and small minimum bend radius.

Available with operating frequency range from DC to 50GHz Intelliconnect cable assemblies are suitable for RF applications including test and measurement systems, high power amplifiers, RF combiners and filters, multi-beam antenna arrays and phased array radars. All Intelliconnect cable assemblies are 100% electrically tested before despatch.
