Introduction
Rogers RT/duroid 5870 high frequency laminates are PTFE composites reinforced with glass microfibers, specifically engineered for the precise demands of stripline and microstrip circuit applications. These composites possess exceptional dielectric constant uniformity due to the presence of randomly oriented microfibers.
RT/duroid 5870 laminates offer high frequency with low dielectric constant (Dk), making them well suited for high frequency/broadband applications where dispersion and losses need to be minimized. Moreover, their low dissipation factor expands the utility to frequencies in the Ku-band and above.
Features
RT/duroid 5870 exhibits a low dielectric constant of 2.33 and a low dissipation factor of 0.0012, verified at 10 GHz.
Due to its PTFE properties, the material demonstrates minimal moisture absorption, as low as 0.02%. This characteristic makes it an ideal choice for environments with high moisture content.
Furthermore, RT/duroid 5870 showcases the lowest electrical loss among reinforced PTFE materials, possesses isotropic properties with uniform electrical characteristics across a range of frequencies, and exhibits excellent resistance to various chemicals.
