The Advanced Circuit Materials (ACM) Division of Rogers Corp. has developed the latest patent-pending innovation in high frequency materials, RT/duroid 5880LZ laminate.

RT/duroid 5880LZ materials tout the lowest Dk for a copper clad laminate available, providing improved antenna efficiency. 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 and allows higher vehicle payloads. With an exceptional TCDK (thermal coefficient of dielectric constant) of 22 PPM/C, 5880LZ enables consistent circuit performance and stable dielectric constant versus temperature.

Rogers ' 5880LZ laminate materials are made using the same high quality, reliable materials and processes. Because of its low dielectric constant of 1.96, RT/duroid 5880LZ supports broadband applications at the microwave through millimeter-wave frequencies where dispersion and circuit losses must be minimized.

5880LZ delivers consistent performance across each board and from panel to panel for critical amplitude- and phase-matched applications. The easy-to-machine material can be supplied as a laminate with a variety of electrodeposited copper weights and with a variety of dielectric thicknesses.
