TLX-7 Substrate High Frequency Laminates Copper Clad Sheet

TLX-7 is a PTFE fiberglass laminate with a dielectric constant (Dk) of 2.6, available in a variety of thicknesses and copper cladding options. It is specifically designed for low-layer-count microwave applications, offering a reliable and versatile platform for RF circuit design.

Ideal for use in radar systems, mobile communications infrastructure, microwave test equipment, transmission devices, and a broad range of RF components, TLX-7 serves as a proven workhorse in the microwave substrate industry. The woven fiberglass construction provides critical mechanical reinforcement, ensuring robust performance in demanding environments such as:

- Creep resistance for PWBs mounted in housings subjected to high vibration during space launch
- High-temperature endurance in engine modules
- Radiation tolerance for space-borne electronics (refer to NASA's low outgassing materials database)
- Resistance to extreme marine conditions for naval antenna systems
- Stable electrical and mechanical performance across wide temperature fluctuations for airborne altimeter applications

The material's broad dielectric constant range also supports the efficient manufacture of couplers, power splitters, combiners, amplifiers, antennas, and other critical RF components.

Benefits
- Excellent PIM performance in PCBs (typically measured below -160 dBc)
- Superior mechanical and thermal properties for long-term reliability
- Low and stable dielectric constant over frequency and temperature
- Excellent dimensional stability for consistent fabrication
- Minimal moisture absorption (<0.1%)
- Tightly controlled Dk for repeatable impedance performance
- Low dissipation factor (Df) for reduced signal loss
- UL 94 V-0 flammability rating
- Optimized for low-layer-count microwave designs

Applications
- Antennas for communications and radar systems
- Mixers, splitters, filters, and combiners
- Passive RF components requiring stable electrical performance
