Rogers RT / Duroid 5880LZ PCB Exploring Lightweight And Capabilities

Rogers RT/duroid 5880LZ laminates are composite materials that are filled with PTFE. They are specifically designed for use in exacting strip-line and micro-strip circuit applications. These laminates contain a unique filler that results in a low density of 1.4 gm/cm3, making them lightweight and ideal for high-performance, weight-sensitive applications.

The RT/duroid 5880LZ PCBs have a very low dielectric constant of 2.0 +/-0.04 and a low dissipation factor ranging from .0021 to .0027 at 10GHz. The dielectric constant is uniform from panel to panel and remains constant over a wide frequency range. The low dissipation factor extends the usefulness of these PCBs to Ku-band and above.

Typical applications of RT/duroid 5880LZ laminates include airborne antenna systems, lightweight feed networks, point-to-point digital radio antennas, and other similar applications.
