Rogers RT/duroid 5870 material specification

Overview of Rogers RT/duroid 5870 High Frequency Laminates

Rogers RT/duroid 5870 high frequency laminates are PTFE composites reinforced with glass microfibers. These laminates offer high frequency performance with a low dielectric constant (Dk). The randomly oriented microfibers in the PTFE composites result in exceptional Dk uniformity, making them well suited for high frequency/broadband applications where dispersion and losses need to be minimized.
