Taconic TLX-7 2-Layer 30mil Immersion Gold PCB for Radar & Microwave Systems
1.Introduction to Core Technologies
TLX-7 is a high-frequency laminate produced by Taconic, engineered to deliver superior electrical performance in demanding RF and microwave applications. It features a low and stable dielectric constant (Dk 2.6) and an extremely low dissipation factor, ensuring minimal signal loss up to millimeter-wave frequencies. Reinforced with woven fiberglass and based on PTFE, TLX-7 offers excellent electrical stability over temperature and frequency, along with reliable thermal and mechanical properties.
