Introduction to TLX-8 Material
TLX-8 is a high-volume antenna material composed of PTFE fiberglass laminates, specifically designed for reliable performance in a broad range of RF applications. Its versatility comes from various thickness options and copper cladding types, making it ideal for low layer count microwave designs. TLX-8 demonstrates mechanical reinforcement in severe environments, including:
- High vibration during space launches
- High temperature exposure in engine modules
- Radiation resistance for space applications
- Extreme conditions at sea for naval antennas
- Wide temperature ranges for altimeter substrates during flight
