Rogers Corp’s Advanced Circuit Materials Division recently introduced rolled copper cladding options with its RO3003, RO3035 and RO3203 low dielectric constant laminate materials. Smooth rolled copper, paired with the very low dielectric loss of the RO3000 PTFE-ceramic resin system, results in high frequency circuit materials with best-in-class insertion loss. These materials are well suited for loss-critical millimeter wave frequency designs, where consistent circuit performance matters, such as automotive radar sensors and point-to-point microwave backhaul communications systems. While already a benchmark for 77 GHz automotive radar sensors, RO3003 3.0 dielectric constant laminates are now available with rolled copper foils from ˝ ounce up to 0.040” thick rolled copper plate, further reducing insertion loss.
RO3000 high frequency circuit materials are ceramic-filled PTFE composites, available in a wide range of dielectric constants, intended for use in commercial microwave and RF applications. This family of products was designed to offer exceptional electrical and mechanical stability at competitive prices. RO3000 series laminates are available without woven fiberglass reinforcement providing circuit materials with unique, electrically isotropic properties compared to competitive material offerings.
