Rogers RT/duroid® 5880 Material Guide

Overview

Rogers RT/duroid® 5880 is an ultra-low-loss, high-frequency PTFE composite laminate developed by Rogers Corporation for demanding RF, microwave, millimeter-wave, aerospace, satellite, and radar applications.

Unlike FR4 and hydrocarbon ceramic laminates such as Rogers 4350B and 4003C, RT/duroid 5880 is based on a PTFE (Polytetrafluoroethylene) composite reinforced with glass microfibers, providing one of the lowest dielectric constants and lowest loss tangents available in commercial PCB materials. Rogers specifies a dielectric constant of 2.20 ± 0.02 and a dissipation factor of 0.0009 at 10 GHz, making it ideal for extremely high-frequency designs.

RT/duroid 5880 is widely used in:

  • 5G Millimeter-Wave Systems
  • Satellite Communications
  • Aerospace Electronics
  • Military Radar Systems
  • RF Antennas
  • Microwave Circuits
  • Spacecraft Electronics
  • High-Speed RF Test Equipment

Because of its exceptional signal integrity and minimal insertion loss, RT/duroid 5880 is considered one of the industry’s benchmark RF laminate materials.
