Developed to optimize the cost to performance ratio, CLTE-AT laminates provide a consistent dielectric constant, regardless of thickness. This commercial version of the CLTE product line has best in class insertion loss and shares many benefits of similar product: CLTE-XT™ laminates.


  • Dielectric constant of 3.00, with minimal change with temperature
  • Very low loss tangent of .0013 at 10GHz
  • Low X, Y and Z-axis CTE of 8, 8, and 20 ppm/°C


  • Excellent dimensional stability required for complex, multi-layer boards (MLBs)
  • Reliable mechanical performance over wide temperature range
  • Low circuit losses
