Phase Stability vs. Flexure is a measure of the phase change of a cable as a result of flexing. The manner of flexure will affect insertion phase. Reducing the bend radius or increasing the bend angle will increase the phase change. Similarly, as the number of flexures increases the phase change will increase. Increasing the ratio of cable diameter to bend diameter will decrease the phase changes. Phase changes over frequency can be considered a linear response, although with some cables change can be more significant at higher frequencies. A microporous dielectric cable will typically have better phase stability than a solid dielectric.
