What Is a Duroid PCB?
A Duroid PCB is a high-frequency printed circuit board manufactured using Rogers RT/duroid laminates, known for their ultra-low dielectric loss, stable dielectric constant, and excellent thermal stability. Duroid PCBs are widely used in RF, microwave, and high-speed digital circuits, where signal integrity and minimal insertion loss are critical.
Common applications include 5G communication modules, aerospace electronics, automotive radar, IoT high-speed devices, and microwave test equipment.
Key Advantages of Duroid PCB
-
Ultra-low dielectric loss (Df as low as 0.0009 @ 10 GHz), minimizing signal attenuation
-
Stable dielectric constant (Dk) for precise controlled impedance
-
High thermal stability, supporting high-power RF circuits
-
Excellent dimensional and mechanical stability, ideal for multilayer stack-ups
-
Low moisture absorption, ensuring reliability in harsh environments
These properties make Duroid PCB the top choice for microwave, millimeter-wave, and high-frequency applications.
Design Considerations for Duroid PCB
1. Controlled Impedance Design
Duroid PCBs are ideal for microstrip, stripline, and differential pair traces, ensuring consistent impedance and minimal reflection.
2. Low-Loss Signal Routing
Optimized trace width, spacing, and routing reduce insertion loss and maintain signal integrity at high frequencies.
3. Thermal and Mechanical Management
Proper copper thickness, via design, and heat dissipation strategies ensure reliable performance under high-power conditions.
4. Multilayer and Hybrid Stack-Ups
Duroid PCBs can be combined with FR-4 or RO4003 in hybrid stack-ups to balance cost and high-frequency performance.
5. Precision Manufacturing
Advanced etching, drilling, lamination, and inspection processes maintain high electrical consistency and repeatability for critical RF applications.
