DiClad870-0300-H1-H1 - Rogers DiClad 870 PTFE/fiberglass Laminate, Dk=2.33, 30 mils, 1 OZ, 12x18''

Rogers DiClad® 870

The Rogers DiClad® 870 is a high-performance PTFE/fiberglass laminate designed for RF, microwave, and high-frequency applications requiring exceptional electrical stability, low loss, and long-term reliability. Thanks to its PTFE woven-glass reinforced structure, DiClad 870 is widely recognized as one of the most stable and repeatable materials in the Rogers portfolio for high-performance printed circuit boards.

This laminate features a dielectric constant (Dk) of 2.33 stable across a wide frequency range, and an ultra-low dissipation factor of 0.0013 at 10 GHz, making it ideal for RF PCBs, low-loss transmission lines, antennas, radar systems, and advanced telecommunication equipment.

In professional engineering environments, Rogers DiClad 870 laminate is used in high-frequency projects where impedance control, dielectric consistency, and low dielectric loss are critical requirements.

Main Features

• Stable Dk 2.33 across the operating band, ideal for RF and microwave applications.

• tanδ 0.0013 @ 10 GHz ensuring very low dielectric loss.

• PTFE/fiberglass reinforced laminate with excellent dimensional stability and low moisture absorption.

• Available in multiple dielectric thicknesses (0.79 mm, 2.36 mm, 3.18 mm and more).

• Compatible with electrodeposited copper in various foil weights.

• Robust and reliable material, ideal for high-precision PCB designs.

Thanks to these characteristics, the DiClad 870 PCB laminate is especially suited for complex circuits requiring low loss and consistent electrical behavior.

Typical Applications

Rogers DiClad 870 is widely used across many high-performance applications, including:

• Phased-array antennas and advanced wireless communication systems.

• Radar systems, RF distribution networks, avionics, and defense electronics.

• RF filters, couplers, planar waveguides, and high-performance feed networks.

• LNA amplifiers, low-loss RF modules, and mmWave components.

• Transmission lines and PCBs for telecom infrastructure.

• High-density and high-stability PCB designs.

Thanks to its electrical consistency and minimal long-term variation, the DiClad 870 microwave laminate ensures predictable performance even in harsh environments or high-power applications.

Benefits for Designers and Manufacturers

• Enhanced impedance control for RF circuits.

• Reduced insertion loss—critical for long-range links and sensitive equipment.

• Excellent dimensional stability, improving manufacturability and reducing scrap.

• Resistance to challenging environmental conditions due to low moisture absorption.

• Compatible with standard high-frequency PCB manufacturing processes.

The Rogers DiClad® 870 is therefore an excellent choice for RF, microwave, and antenna applications where signal consistency, low loss, and long-term reliability are essential.
