RO3003 2-Layer 1.4mm PCB – 50mil Ceramic-Filled PTFE with ENIG for RF & Automotive Radar

1. Introduction to RO3003 2-Layer 1.4mm PCB

Rogers RO3003 high frequency laminates are ceramic-filled PTFE composites designed for commercial microwave and RF applications. These laminates provide exceptional stability of dielectric constant (Dk) across various temperatures and frequencies. A key advantage is the elimination of the step change in Dk that typically occurs near room temperature with conventional PTFE glass materials. This characteristic makes RO3003 ideal for demanding applications including automotive radar (77 GHz), advanced driver assistance systems (ADAS), and 5G wireless infrastructure (mmWave).
