The Arlon PCB 8-Layer CLTE-XT board is a highly stable, micro-dispersed ceramic PTFE laminate designed for advanced aerospace RF backplane architectures. Operating in demanding microwave environments requires materials that resist dimensional change, and this multilayer fabrication ensures minimal insertion loss and excellent phase stability. Engineered for structural reliability, it bridges the gap between complex digital processing and high-frequency RF distribution.

Key Features of Arlon 8-Layer PCB CLTE-XT

• Material Matrix: Micro-dispersed ceramic PTFE (Arlon CLTE-XT) for low moisture absorption.

• Dielectric Constant (DK): Controlled at 2.94 ($\pm 0.04$) to maintain uniform impedance.

• Dissipation Factor (DF): Low loss tangent of 0.0012 at 10 GHz.

• Layer Count: 8-layer rigid construction optimized for RF and digital signal segregation.

• Thermal Stability: Low CTE ($X/Y \approx 8 \text{ ppm/}^\circ\text{C}$, $Z \approx 20 \text{ ppm/}^\circ\text{C}$) ensures reliable plated through-hole (PTH) reliability during thermal cycling.

• Surface Finish: ENIG (Electroless Nickel Immersion Gold) for superior solderability and oxidation resistance.

Applications

• Aerospace and Defence: Military radar arrays, electronic warfare systems, and satellite communication transceivers.

• RF Backplanes: High-speed commercial telecommunications backplanes and base station power amplifiers.

• Navigation Instrumentation: Airborne guidance subsystems and phased-array antenna feeds.
