High-Performance RO3003 4-Layer HDI PCB 2.4mm Thick Circuit Boards for Advanced Applications

(Custom PCBs are tailored products; the images and specifications provided are for reference only.)

Introduction to RO3003

Rogers RO3003 high-frequency laminates are ceramic-filled PTFE composites designed for commercial microwave and RF applications. These laminates provide excellent stability of dielectric constant (Dk) over various temperatures and frequencies, eliminating the typical step change in Dk that occurs with PTFE glass materials. This makes RO3003 ideal for applications such as automotive radar (77 GHz), advanced driver assistance systems (ADAS), and 5G wireless infrastructure (mmWave).
