AD250C laminates are built on a cost-effective combination of composite chemistry and construction to yield an uncompromising level of price-performance for today’s telecommunication infrastructure.


  • Very low loss PTFE and ceramic filled composite (.0014 loss tangent at 10GHz and base station frequencies)
  • Dielectric constant (Dk) of 2.50 +/-.04
  • Low profile copper for lower conductive losses
  • Lower Z-Direction CTE of 50 ppm/°C
  • Larger panel sizes available


  • Higher antenna efficiencies
  • Low PIM for antenna applications
  • Ceramic provides higher degree of Dk stability during temperature changes
  • Improved plated through-hole (PTH) reliability, compared to typical PTFE based laminates
