PCB Material TLY-3 High Frequency Laminates Copper Clad Sheet

TLY-3 laminates are fabricated using ultra-lightweight woven fiberglass, offering significantly greater dimensional stability compared to chopped fiber-reinforced PTFE composites. The woven fiberglass matrix delivers a mechanically robust laminate ideal for high-volume production. Featuring an extremely low dissipation factor, TLY-3 performs reliably in 77 GHz automotive radar systems and other millimeter-wave antenna designs.

Comparative OEM testing at 77 GHz between low-reinforcement TLY-3 and its nearest chopped fiber-reinforced competitor demonstrated comparable “drop-in” insertion loss and dielectric performance, with the key advantage of drastically improved manufacturing yields. The dielectric constant (Dk) ranges from 2.17 to 2.40. For most thicknesses, Dk can be specified at any value within this range with a tight tolerance of ±0.02. At 10 GHz, the typical dissipation factor (Df) in the low-Dk region is approximately 0.0009.

Typical applications include satellite communications, automotive radar, filters, couplers, avionics, and phased-array antennas.
