TLX-8 PCB Material High Frequency Laminates Copper Clad Sheet

TLX-8 delivers consistent and dependable performance across a broad spectrum of RF applications. Its versatility stems from a customizable 2.45–2.65 dielectric constant range, along with multiple thickness and copper cladding options, making it especially well-suited for low-layer-count microwave designs.

As a PTFE fiberglass laminate, TLX-8 is ideal for use in radar systems, mobile communications, microwave test equipment, transmission devices, and various RF components. It serves as a reliable workhorse in the RF microwave substrate industry, with fiberglass reinforcement providing critical mechanical stability in demanding environments, including:

- Creep resistance for PWBs mounted in housings subject to intense vibration during space launch
- Endurance in high-temperature engine modules
- Radiation tolerance in space applications (see NASA’s low outgassing materials database)
- Resistance to extreme marine conditions for naval antenna systems
- Stable performance across wide temperature fluctuations in airborne altimeter applications

The material’s broad dielectric constant range enables the efficient manufacture of couplers, splitters, combiners, amplifiers, antennas, and other critical components.
