Low-Loss PTFE PCB Material – Taconic TLY-5 Manufacturer & Assembly
Discover Taconic TLY-5 PCB laminates with ultra-low loss (Df 0.0009) and stable Dk for high-frequency RF, 5G, and radar systems. Expert PCB manufacturing from Highleap Electronics.
The Go-To PTFE Laminate for 5G & Low-Loss RF PCB Designs
Taconic TLY-5 is a high-performance PTFE-based PCB laminate engineered for ultra-high-frequency applications—from 24 GHz 5G modules to 77 GHz automotive radar systems. As RF engineers face increasing demands for speed, density, and stability, TLY-5 PCB material for 5G and millimeter-wave designs has become a reliable go-to choice.
With an ultra-low dissipation factor of 0.0009 at 10 GHz, and a stable dielectric constant of 2.20, it enables low-loss signal transmission and consistent impedance control—making it ideal for phased-array antennas, low-noise amplifiers, beamforming networks, and high-frequency microwave PCBs.
Unlike ceramic or FR4-based laminates, TLY-5 PTFE laminate for RF PCBs offers excellent dimensional stability, thermal reliability, and compatibility with high-frequency fabrication processes.
Whether you’re developing a mmWave radar module, satellite transceiver, or a 5G front-end RF circuit, Taconic TLY-5 circuit boards deliver superior electrical performance while minimizing signal distortion and loss.
See the full technical breakdown below to understand why TLY-5 is a top-tier material for your next-generation high-frequency PCB.
