RT-duroid® 6002 laminates are PTFE-based high-frequency circuit materials reinforced with ceramic fillers. These laminates offer an exceptional combination of electrical and mechanical properties, making them ideal for microwave and RF applications. Their low dielectric constant (DkD_kDk​) and loss tangent are particularly suited for high-performance antennas, filters, and other critical RF components.

Key Features

1. Low Dielectric Constant (DkD_kDk​):
   • Typical DkD_kDk​: 2.94 (±0.04)
   • Nearly isotropic DkD_kDk​, ensuring minimal variation across axes.
2. Low Loss Tangent (tan⁡δ\tan\deltatanδ):
   • Typical tan⁡δ\tan\deltatanδ: 0.0012 at 10 GHz
   • Ideal for minimizing signal loss in high-frequency applications.
3. Thermal Stability:
   • Excellent dimensional stability and low thermal expansion.
4. Mechanical Robustness:
   • Ceramic reinforcement improves rigidity and reduces creep under mechanical stress.
5. Easy Machinability:
   • Supports precision processing, including drilling, milling, and etching.

Applications

• Aerospace and satellite communications
• High-frequency antennas and radars
• RF and microwave filters and couplers
• High-speed digital circuits
