Duroid 5880 PCB – Ultra Low Loss PCB for High Frequency and Radar Applications

What Is a Duroid 5880 PCB?

A Duroid 5880 PCB is a high frequency printed circuit board manufactured using Rogers RT/duroid 5880 laminate, a PTFE-based material known for its ultra-low dielectric constant and extremely low dissipation factor.

Duroid 5880 PCB is widely used in:

• Radar systems

• Satellite communication modules

• mmWave applications

• Aerospace RF systems

• High frequency antennas

Because high frequency signals are highly sensitive to material loss, Duroid 5880 PCB ensures minimal insertion loss and excellent signal integrity even at microwave and millimeter-wave frequencies.

Key Properties of Duroid 5880 PCB

1. Ultra-Low Dielectric Constant (Dk)

Duroid 5880 features:

• Dk ≈ 2.20 ± 0.02

• Excellent stability across frequency range

Low Dk allows:

• Faster signal propagation

• Reduced signal delay

• Optimized antenna performance

2. Extremely Low Dissipation Factor (Df)

With Df ≈ 0.0009 at 10 GHz, Duroid 5880 PCB provides:

• Minimal signal attenuation

• Low insertion loss

• Improved RF efficiency

This makes it ideal for microwave and mmWave PCB design.

3. Stable Performance at High Frequency

Duroid 5880 PCB supports:

• Ku-band and Ka-band frequencies

• mmWave radar modules

• High precision RF filters and amplifiers

Stable dielectric properties ensure predictable RF behavior and repeatable manufacturing.

4. Lightweight and Aerospace-Ready

The PTFE composite structure provides:

• Low density

• High reliability

• Good thermal stability

Duroid 5880 PCB is frequently selected for aerospace and satellite systems, where weight and performance are critical.

Applications of Duroid 5880 PCB

Duroid 5880 PCB is widely used in:

• Automotive radar systems

• Satellite communication equipment

• 5G mmWave modules

• Military RF systems

• High frequency antenna arrays

• Microwave test equipment

These applications demand ultra-low loss, controlled impedance, and high frequency precision.

Duroid 5880 PCB vs Standard FR-4 PCB

Duroid 5880 PCB significantly outperforms FR-4 in high frequency and RF applications.

Manufacturing Considerations

Fabricating Duroid 5880 PCB requires:

• Specialized PTFE processing techniques

• Precise impedance control

• Controlled lamination pressure and temperature

• Careful drilling and plating processes

• Experienced high frequency PCB fabrication capability

Because PTFE materials behave differently from FR-4, working with an experienced manufacturer is essential.

Conclusion

Duroid 5880 PCB delivers ultra-low loss, stable dielectric performance, and superior signal integrity for high frequency, radar, satellite, and mmWave applications.

By choosing Duroid 5880 PCB, engineers ensure reliable RF transmission, reduced signal attenuation, and optimized high frequency system performance.
