Introduction to RO3203
RO3203 High Frequency Circuit Materials are ceramic-filled laminates reinforced with woven fiberglass. They are designed to deliver exceptional electrical performance and mechanical stability at competitive prices. RO3203 is an extension of the RO3000 Series, featuring improved mechanical stability. With a dielectric constant of 3.02 and a dissipation factor of 0.0016, these materials are suitable for frequencies exceeding 40 GHz.
