Taconic TLY-3 DK2.33 Avionics & Aerospace Grade Low DK Base Material
Overview
TLY-3 laminates are crafted using ultra-lightweight woven fiberglass, boasting significantly enhanced dimensional stability compared to chopped fiber reinforced PTFE composites. The woven matrix integrated into the TLY-3 material results in a laminate with superior mechanical stability, making it well-suited for high-volume production processes. Thanks to its low dissipation factor, this TLY-3 copper clad laminate can be successfully applied in 77 GHz automotive radar systems as well as various millimeter-wave frequency antennas.
In comparative OEM testing conducted at 77 GHz, the lightly reinforced Taconic TLY-3 demonstrated "drop-in" compatibility and equivalent insertion losses and dielectric properties when pitted against its closest competitor featuring chopped fiber reinforcement. Its key advantage lies in substantially higher manufacturing yields. The dielectric constant of TLY-3 Base Material ranges from 2.17 to 2.40, and for most thicknesses, it can be specified to any value within this range with a tolerance of +/- 0.02. At 10 GHz, within the low dielectric constant range, the dissipation factor is approximately 0.0009. Common applications include satellite communications, automotive radar, filters, couplers, avionics, and phased array antennas.
