RT Duroid 6202 High Frequency PCB Engineering Complex Microwave Designs with Precision

October 4, 2025

In the world of high-frequency electronics, performance starts with the substrate. For designers who need consistent electrical properties, mechanical stability, and ultra-low signal loss, Rogers RT/duroid® 6202 stands out as a trusted high-frequency laminate.

Ideal for demanding RF and microwave applications, this material combines a low dielectric constant with minimal woven glass reinforcement—delivering both electrical precision and dimensional reliability.

What Is RT/duroid 6202?

RT/duroid 6202 is a high-frequency circuit material engineered for complex microwave structures. Its balanced construction offers:
Low dielectric constant with tight tolerance
Ultra-low dissipation factor
Excellent dimensional stability

The limited woven glass reinforcement reduces the need for double-etching, simplifies fabrication, and helps maintain tight positional tolerances—making it easier to achieve high-performance designs without compromising manufacturability.

Key Material Properties and Benefits

1.Stable Dielectric Constant:

Dk ranges from 2.94 to 3.06 (depending on thickness), with an exceptionally tight tolerance of ±0.04.

2.Ultra-Low Loss:

Dissipation factor of just 0.0015 at 10 GHz, enabling high-efficiency signal transmission.

3.Thermal Stability:

Low thermal coefficient of Dk—only 5 ppm/°C—ensures consistent performance across temperature variations.

4.Dimensional Control:

In-plane expansion is closely matched to copper, and etch shrinkage is minimal, supporting fine-line circuitry and multilayer designs.
