1. Introduction of RO3003

Rogers RO3003 high-frequency laminates are ceramic-filled PTFE composites designed for commercial microwave and RF applications. These laminates provide exceptional stability in dielectric constant (Dk) across a range of temperatures and frequencies. Notably, they eliminate the step change in Dk commonly seen near room temperature in PTFE glass materials. This makes them particularly suitable for applications such as automotive radar (77 GHz), advanced driver assistance systems (ADAS), and 5G wireless infrastructure (mmWave).
