Manufacturers design RO4400 dielectric materials in Rogers RO4400 and RO4400T series RF connectors. These dielectric materials are low-loss and resistive-type data cables. Additionally, they have an excellent shielding performance offered in wide lengths and configurations to meet almost any application. As a result, the low-loss dielectric material minimizes the amount of loss caused by the cable and its insulation. This results in a reduction in losses during signal transmission between RF connectors. They then submit the signals through a greater portion of the cable length.

The dielectric materials are helpful for data cables, where the cable’s impedance is low. So, they are good in applications where most signals travel along the entire cable length without being routed through internal wiring. Additionally, the dielectric material is ideal for medical applications. Examples include magnetic resonance imaging (MRI) equipment that uses 26 to 28 AWG conductor sizes. In addition, these dielectric materials are essential with Rogers RO4400 and RO4400T series connectors.

Materials

End-to-end cable assemblies consist of copper or copper alloy conductors. Therefore, the RO6400 and RO4400 dielectric materials consist of various materials, including Mylar. These 32-AWG (0.01-inch) Mylar conductors feature excellent shielding performance and low capacitance for cable data applications. In addition, the configuration of the RO6400 and RO4400 dielectric materials is suitable for data transmission in any environment. Finally, they work best where signals must pass through the entire length of the cable without being shifted through internal wiring.
