When signal integrity at high frequencies is paramount, standard flex materials reach their limits. Rogers Corporation's advanced laminates and similar high-frequency materials provide the low loss, tight dielectric tolerance, and stable properties needed for RF, microwave, and high-speed digital applications.
These specialized materials offer dielectric constants (Dk) ranging from 2.2 to 10.2 with tight tolerances, enabling precise impedance control at frequencies from DC to 77 GHz and beyond. Loss tangent (Df) values as low as 0.0009 minimize signal attenuation critical for sensitive receiver front ends and long transmission lines.
Our high-frequency flex capability combines these premium materials with the manufacturing precision needed to realize their potential. Tight impedance control, fine features, and careful attention to transitions and interfaces deliver flex circuits that perform to specification in demanding RF environments.
