RF-10 High Frequency PCBs Enable Compact and Reliable RF Designs

September 26, 2025

As RF systems continue to demand higher performance in smaller form factors, the choice of substrate material becomes increasingly important. RF-10 high-frequency laminates offer a compelling combination of high dielectric constant, low loss, and excellent dimensional stability—making them an ideal solution for compact, high-reliability RF circuits.

Whether you're designing patch antennas, satellite components, or aerospace systems, RF-10 provides the electrical and mechanical properties needed for challenging applications.

What Is RF-10?

RF-10 is a ceramic-filled PTFE laminate reinforced with woven fiberglass. This composite structure delivers low dielectric loss and improved handling rigidity, while also supporting strong dimensional stability—especially valuable in multilayer circuit designs.

Its balanced expansion characteristics across all axes ensure reliable plated through-holes and reduce the need for complex artwork compensation.

Key Features & Benefits

1.High Dielectric Constant

With a Dk of 10.2 ±0.3, RF-10 allows for significant circuit size reduction—ideal for compact RF designs.

2.Low Loss Performanc

A dissipation factor of 0.0025 at 10 GHz helps maintain signal integrity and minimize attenuation.

3.Improved Thermal Management

Thermal conductivity of 0.85 W/m·K (unclad) supports effective heat dissipation, reducing the risk of thermal-related failures.

4.Strong Copper Adhesion

The laminate bonds reliably to smooth copper surfaces, enhancing interfacial integrity and reliability.

5.Low CTE in All Directions

X-axis: 16 ppm/°C
Y-axis: 20 ppm/°C
Z-axis: 25 ppm/°C

This uniform low expansion improves plated through-hole reliability and reduces thermal stress.
