RT/duroid 5880 PCB: The High-Performance PCB Solution for Cutting-Edge RF and Microwave Applications


In the rapidly evolving world of high-frequency electronics, the demand for reliable, high-performance printed circuit board (PCB) materials has never been greater. As engineers push the boundaries of innovation, they require PCB substrates that can keep pace with the increasing complexity and performance demands of modern RF and microwave systems. Enter RT/duroid 5880, a game-changing PCB material from Rogers Corporation that is poised to revolutionize the industry.

Engineered for Excellence

Rogers 5880 PCB is a premier PTFE-based composite laminate designed to provide unparalleled electrical and mechanical properties for a wide range of high-frequency applications. Reinforced with glass microfibers, this material boasts a remarkably low dielectric constant (Dk) of 2.2 with a tight tolerance of ±0.02 at 10 GHz and 23°C. Equally impressive is its exceptionally low dissipation factor (Df) of just 0.0009 at 10 GHz, ensuring minimal signal loss and superior high-frequency performance.

One of the standout features of RT/duroid 5880 125mil substrate PCB is its temperature stability. With a temperature coefficient of dielectric constant (TCDk) of -125 ppm/°C, this material maintains its electrical characteristics remarkably well across a wide operating temperature range. This makes it an ideal choice for applications that must withstand demanding environmental conditions, such as commercial airline broadband antennas, radar systems, and guidance systems.

Moisture Resistance and Dimensional Stability

In addition to its exceptional electrical properties, Rogers 5880 substrate also boasts impressive moisture resistance and dimensional stability. With a moisture absorption rate of just 0.02%, this material is well-suited for use in high-moisture environments, ensuring reliable performance even in challenging conditions.

The dimensional stability of RT/duroid 5880 is equally impressive, with a coefficient of thermal expansion (CTE) of 31 ppm/°C in the X-axis, 48 ppm/°C in the Y-axis, and 237 ppm/°C in the Z-axis. This isotropic behavior helps maintain the integrity of the PCB's design, even under thermal stress, making it an excellent choice for applications that require tight dimensional tolerances.

Versatile Applications

The exceptional performance characteristics of RT/duroid 5880 make it a versatile choice for a wide range of high-frequency applications. From commercial airline broadband antennas to microstrip and stripline circuits, millimeter-wave applications, radar systems, guidance systems, and point-to-point digital radio antennas, this material has the flexibility to meet the diverse needs of the industry.

One particularly notable application is in commercial airline broadband antennas, where RT/duroid 5880's low dielectric constant and low loss tangent are crucial for maintaining high-quality signal transmission. The material's thermal stability and moisture resistance also make it well-suited for the demanding environmental conditions encountered in airborne applications.

In the realm of radar systems and guidance systems, the exceptional electrical properties of RT/duroid 5880 are instrumental in ensuring accurate and reliable performance. The material's low dielectric constant and low loss tangent help minimize signal distortion and maintain the integrity of critical RF and microwave signals, even in the most challenging operating environments.

Millimeter-wave applications, such as point-to-point digital radio antennas, also benefit greatly from the unique characteristics of RT/duroid 5880. The material's ability to maintain its electrical properties at higher frequencies, coupled with its dimensional stability, makes it an ideal choice for the precision-engineered components required in these cutting-edge systems.

Seamless Integration and Fabrication

Integrating Rogers RT duroid 5880 into your PCB design is a straightforward process, thanks to its well-established reputation and widespread availability. The material is easily cut, shared, and machined to shape, allowing for flexible and efficient manufacturing processes.

Moreover, Rogers RT/duroid 5880 PCB is highly resistant to the solvents and reagents used in etching or plating edges and holes, ensuring a seamless fabrication process and minimizing the risk of material degradation. This, combined with the material's inherent dimensional stability, helps maintain the integrity of the PCB design throughout the manufacturing chain.


In the rapidly evolving world of high-frequency electronics, RT/duroid 5880 material PCB from Rogers Corporation stands out as a true game-changer. With its exceptional electrical properties, thermal stability, moisture resistance, and dimensional stability, this PTFE-based composite laminate is poised to become the go-to choice for a wide range of cutting-edge RF and microwave applications.

Whether you're designing commercial airline broadband antennas, radar systems, guidance systems, or point-to-point digital radio antennas, RT/duroid 5880 high frequency PCB offers the performance, reliability, and flexibility needed to push the boundaries of innovation. As the demand for high-performance PCB materials continues to grow, this industry-leading solution from Rogers Corporation is sure to be at the forefront of the next generation of high-frequency electronics.
