Millimeter wave / Microwave Flexible Coaxial Cable Assembly

Model No. MMT02

This flexible coaxial cable can be easily and freely bent by hands to fit to or in your devices.
Based on its longtime experience in the industry, KEYCOM’s cable assemblies are designed to be simple yet practical.
Because PTFE foam is used for the dielectric insulation, this cable assembly possesses low loss and high phase stability.
It is also ideal for measurement applications.
