Evidence
The classification of CCL materials is determined by its dielectric constant (Dk) and dissipation factor (Df) at a given frequency. Insertion loss is lower at lower Dk and Df value. The common classification is anchored to the Megtron series from Panasonic as they have been setting the industry standard. When people describe the CCL as M7 classification it usually means it matches the same Dk and Df specifications as Megtron 7 of Panasonic.
