1.Introduction to RT/duroid 5870 PCB Material

Rogers RT/duroid 5870 high frequency laminates are PTFE-glass microfiber composites engineered for precision stripline and microstrip circuits. Featuring randomly oriented microfibers, these laminates deliver exceptional dielectric constant uniformity, making them ideal for:
High-frequency broadband applications
Ku-band and millimeter wave circuits
Low-loss, low-dispersion designs

2.Key Features of RT/duroid 5870

Ultra-low Dk (2.33) & Dissipation (0.0012 @ 10 GHz)
Minimizes signal loss for high-frequency performance
Near-zero moisture absorption (0.02%)
Reliable in humid environments
Lowest electrical loss among reinforced PTFE materials
Isotropic properties for uniform performance across frequencies
Chemical-resistant for harsh applications
