Material Overview: Rogers DiClad 870

DiClad 870 laminates are PTFE-based, woven fiberglass-reinforced materials designed for RF and microwave applications. They provide lower dielectric constants and dissipation factors compared to other laminates, making them ideal for circuits requiring high precision and efficiency.

With its low moisture absorption and stable Dk, DiClad 870 ensures consistent performance under varying environmental conditions, making it reliable for critical RF designs.

Benefits

The low dissipation factor minimizes signal loss, ensuring high efficiency in RF applications.

The dielectric constant remains consistent across a wide frequency range, supporting precise signal transmission.

With high thermal conductivity and a low coefficient of thermal expansion (CTE), this PCB maintains mechanical stability and durability under extreme conditions.

DiClad 870 laminates meet stringent green standards with halogen-free options and low moisture absorption.

Applications

The 2-Layer DiClad 870 PCB excels in high-frequency applications, including:

Base station antennas, digital radio systems

Radar feed networks, guidance systems

Filters, couplers, low-noise amplifiers (LNAs)

Conclusion

The 2-Layer DiClad 870 PCB with Immersion Silver Finish provides a reliable, high-performance option for engineers working on RF and microwave designs. With its low-loss properties, stable dielectric constant, and thermal reliability, it is ideal for applications such as radar systems, phased array antennas, and mobile communication systems. Whether you're designing for telecommunications or aerospace, this PCB meets the highest standards of quality and performance, ensuring success in your most demanding projects.
