The Arlon AR320 Ceramic PTFE PCB is a high-performance 4-layer low-loss RF board designed specifically for complex high-frequency and microwave circuitry. Engineered with a woven fiberglass reinforced ceramic-filled PTFE composite, this substrate provides exceptional dimensional stability and mechanical strength. It serves as a critical component for RF engineers, product developers, and procurement managers who require precise signal integrity, minimal insertion loss, and reliable thermal management in high-power wireless environments.
Key Features of Arlon AR320 Ceramic PTFE PCB Substrates
-
Dielectric Constant (DK): Stably rated at 3.20 at 10 GHz, ensuring predictable impedance control across wide bandwidths.
-
Dissipation Factor (DF): Ultra-low loss tangent of 0.0030 at 10 GHz to minimize signal attenuation in high-frequency channels.
-
Layer Count: Advanced 4-layer stackup configuration optimized for complex RF power distribution and grounding networks.
-
Thermal Conductivity: Enhanced thermal performance ($0.48 \text{ W/m}\cdot\text{K}$) for efficient heat dissipation in power amplifiers.
-
Moisture Absorption: Extremely low moisture absorption rate (0.04%) ensures electrical property stability in humid environments.
-
Compliance and Standards: Fully compatible with lead-free roasting processes and compliant with IPC-4103 specifications.
