What is Junflon MWX® ?

Junkosha is a pioneer of sophisticated fluoropolymer application technologies across a broad selection of industries, including the microwave interconnect sectors. With a core message of ‘phase performance that endures’, our MWX range of microwave coaxial cable assemblies are flexible signal transmission lines that take advantage of the excellent properties of PTFE and are used in applications up to 120 GHz. In addition, they are ideal for use with Vector Network Analyzers for precision measurement requirements. Overall, Junkosha offers a wide range of highly reliable assemblies for micro/millimeter wave applications that are tailored to customers’ needs.

What is "Phase Performance that Endures"?


Microwave coaxial cables are subject to phase changes, which are caused by either bending the cables or from temperature fluctuations.


Our cables are extremely flexible and feature a high degree of phase reproducibility.


The result is cabling that has excellent durability and maintains phase stability for a long period of time.
