high frequency PCBs

Rogers RT5880 laminatehave the lowest Dk for a copper clad laminate available in the market today. Because of its low dielectric constant of 1.96 at 10 GHz, RT/duroid 5880LZ supports broadband applications at the microwave through millimeter-wave frequencies where dispersion and circuit losses must be minimized. It is a lightweight, PTFE-based composite optimized with a unique filler that provides very low density (1.37 gm/cm3) and a low coefficient of thermal expansion (CTE) in the Z-axis. This makes 5880LZ well suited for fabricating high-frequency circuits with plated-through holes (PTH) and allows higher vehicle payloads. In addition, the dielectric constant is uniform from panel-topanel and constant over a wide frequency range. Its low dissipation factor extends the usefulness of RT 5880 to K-band and above.
