RT/duroid® 5880 High-Frequency PTFE Laminate (0.508mm / 20 mil, 1 oz/ft² Copper Cladding) is a premium glass microfiber-reinforced PTFE substrate engineered for demanding high-frequency and microwave circuit applications where signal integrity and dimensional stability are critical.
Key Features & Specifications:
- Dielectric Constant (Dk): 2.20 ± 0.02 — exceptionally low and stable across a wide frequency range (1 GHz to 40 GHz+), minimizing signal dispersion in high-speed designs
- Dissipation Factor (Df): 0.0009 at 10 GHz — among the lowest loss tangents available for commercial microwave laminates, ideal for low-noise and low-insertion-loss circuits
- Thickness: 0.508mm (20 mil) with tight tolerance control, ensuring consistent impedance across production runs
- Copper Cladding: 1 oz/ft² (35 µm) electrodeposited or rolled copper, suitable for fine-line etching and controlled impedance stripline/microstrip structures
- Thermal Stability: Low Z-axis CTE and excellent thermal performance, supporting reliable operation across wide temperature cycling environments
Applications & Industries:
RT/duroid® 5880 laminate is widely used in high-frequency circuit boards operating at millimeter-wave and microwave frequencies. Typical applications include patch antennas, phased array antenna feeds, radar front-end modules, satellite communication (SATCOM) subsystems, power amplifier boards, LNA (low-noise amplifier) circuits, automotive radar (77 GHz ADAS systems), and aerospace avionics electronics. It is also suitable for test and measurement equipment, point-to-point wireless links, and high-frequency filter networks where low dielectric loss and phase stability are essential.
