Low Loss Phase Stable Cable UniFlex ULA520

In radio frequency and microwave systems, phase variations of its sub assemblies and components have become increasingly sensitive. If appropriate selections are made while selecting and constructing these components, the linking backbone of these systems, cable assemblies, can be a substantial source of poor system performance. ePTFE is a previously unavailable material that offers much better phase performance than PTFE, Si02, or other standard cables. This is necessary for many applications to get the desired outcomes. A decreased amplitude of phase change and better phase tracking with changing temperatures result in lower residual errors and uncertainties. Our cable provides good temperature phase stability as well as mechanical phase stability.
