1.  Introduction of RO3203

RO3203 High Frequency Circuit Materials are ceramic-filled laminates reinforced with woven fiberglass. These materials are engineered to offer exceptional electrical performance and mechanical stability at competitive prices. The RO3203 High Frequency Materials were designed as an extension of the RO3000 Series High Frequency Circuit Materials with one distinguishing characteristic - improved mechanical stability. The dielectric constant of RO3203 High Frequency Circuit Materials is 3.02. This, along with a dissipation factor of 0.0016, extends the useful frequency range beyond 40 GHz.
