Taconic TLX-6 DK 2.65 Df0.0016/0.0022 (0.089-6.35mm) Copper Clad Laminate
Brief Introduction
TLX is a high-volume fiberglass-reinforced microwave substrate offering reliability across a wide range of RF applications. Its versatility stems from a DK range of 2.45–2.65, various available thicknesses, and copper cladding options, making it suitable for low-layer-count microwave designs. TLX PTFE fiberglass laminates are ideal for radar systems, mobile communications, microwave test equipment, transmission devices, and RF components. As a robust substrate for severe environments, its fiberglass reinforcement provides mechanical strength against vibration, high temperatures, radiation, and wide temperature ranges.
Technical Features & Benefits
- Excellent PIM Values in PCBs: Measured lower than -160 dBc, ensuring superior intermodulation performance.
- Excellent Mechanical & Thermal Properties: Fiberglass reinforcement provides strength against vibration, high temperatures, and radiation.
- Low and Stable Dielectric Constant (Dk): Dk = 2.65 ±0.04 at 10 GHz for consistent electrical performance.
- Dimensionally Stable: Reliable fabrication and assembly with minimal movement.
- Low Moisture Absorption: 0.02% moisture absorption maintains electrical properties in humid environments.
- Tightly Controlled DK: Ensures repeatable circuit performance across panels and batches.
- Low Dissipation Factor (Df): Df of 0.0016 @ 1.9GHz and 0.0022 @ 10GHz for minimal signal loss.
- UL 94 V-0 Flammability Rating: Meets industry safety standards for flame resistance.
- Suitable for Low Layer Count Microwave Designs: Ideal for cost-effective, high-performance RF circuits.
