What Makes TFA615 Unique?

About TFA Series

TFA series substrates are polytetrafluoroethylene (PTFE) ceramic composites, crafted without traditional glass fiber cloth. Instead, they use a new prefabrication process and special lamination, resulting in aerospace-grade performance that rivals foreign alternatives. Key traits:

-No glass fiber cloth, eliminating "fiberglass effect" in electromagnetic wave propagation

-Uniform nano-ceramic mix for stable frequency performance and minimal dielectric loss

-Low anisotropy (X/Y/Z) and copper-matched thermal expansion

-Stable dielectric temperature characteristics

-Four dielectric constant options: 2.94 (TFA294), 3.0 (TFA300), 6.15 (TFA615), 10.2 (TFA1020)

TFA615 Features

-Dielectric constant (Dk): 6.15±0.12 at 10GHz

-Dissipation factor: 0.0015 at 10GHz; 0.0017 at 20GHz

-CTE (–55°C to 288°C): X=16 ppm/°C, Y=16 ppm/°C, Z=29 ppm/°C

-Thermal conductivity: 0.8 W/mk

-Moisture absorption: 0.06%

-UL 94-V0 rating

-Td (decomposition temperature): 503℃

Ideal Applications

-Aerospace equipment, spacecraft, and in-cabin systems

-Microwave components and antennas (including phase-sensitive types)

-Early warning radars and airborne radars

-Phased array antennas and beamforming networks

-Satellite communications and navigation systems

-Power amplifiers
