Introduction to CLTE-XT Material

Rogers CLTE-XT laminates are composites of micro-dispersed ceramic filler, PTFE, and woven fiberglass reinforcement, designed to provide the lowest insertion loss and the highest dimensional stability in their class. With a dielectric constant (Dk) ranging from 2.79 to 2.94 and a dissipation factor of just 0.0010 at 10GHz, CLTE-XT ensures superior electrical performance, even at high frequencies.


Key Features of CLTE-XT

  • Stable Dielectric Constant (Dk): Ranges between 2.79 and 2.94, with ±0.03 tolerance, ensuring consistent performance.
  • Low Dissipation Factor: Just 0.0010 at 10GHz for minimal signal loss.
  • Thermal Stability: High Td of 539°C and low CTE values (X: 12.7 ppm/°C, Y: 13.7 ppm/°C, Z: 40.8 ppm/°C).
  • Moisture Resistance: Absorption rate of 0.02%, ensuring stable performance in humid conditions.

Benefits of CLTE-XT

  • High Reliability: Excellent plated-through-hole performance and repeatable lot-to-lot results.
  • Dimensional Stability: Reduced stress during attachment to ceramic active devices.
  • Low Circuit Losses: Maintains performance without sacrificing structural integrity.

Applications

  • Advanced Driver Assistance Systems (ADAS)
  • Patch Antennas
  • Phased Array Antennas
  • Power Amplifiers
  • Ground-Based and Airborne Radar Systems

Conclusion

The CLTE-XT 2-layer PCB is a high-performance solution for RF and microwave applications, offering low insertion loss, dimensional accuracy, and excellent mechanical durability. With its 5.1mil Rogers CLTE-XT core and immersion gold finish, it provides the reliability and consistency required for critical communication systems like ADAS, satellites, and radar systems.


Engineered to meet IPC-Class-2 standards and available worldwide, the CLTE-XT PCB is the perfect choice for engineers seeking cost-effective, high-frequency solutions.
