The Arlon PCB AR450 Microwave PCB is a specialized 4-layer circuit board designed to meet the rigorous thermal and electrical demands of modern high-frequency power amplifiers. Engineered for aerospace, defense, and advanced telecommunication infrastructure, this board utilizes a woven fiberglass reinforced, ceramic-filled hydrocarbon/fluoropolymer composite. This unique material composition ensures exceptional dimensional stability and consistent performance across a wide temperature range, making it the premier choice for hardware developers who cannot compromise on signal integrity.
Key Features
-
Dielectric Constant (DK): Controlled DK of $4.50 \pm 0.15$ at 10 GHz for precise impedance matching.
-
Dissipation Factor (DF): Low loss tangent of 0.0035 at 10 GHz to minimize signal attenuation in high-power circuits.
-
Layer Count & Stackup: 4-layer balanced stackup optimized for effective heat dissipation and low-noise ground planes.
-
Thermal Conductivity: Enhanced thermal management capability ($0.65 \text{ W/m}\cdot\text{K}$) to safely dissipate heat from power amplifier transistors.
-
Moisture Absorption: Extremely low moisture absorption rate (<0.10%) ensuring electrical stability in humid operating environments.
-
Surface Finish Options: Available with ENIG (Electroless Nickel Immersion Gold) or HASL-LF to support reliable component pitching and high-reliability soldering.
Applications
-
Base Station Amplifiers: Power amplifiers for cellular infrastructure and telecommunications networks.
-
Aerospace & Defense: Radar systems, satellite communications transceivers, and telemetry equipment.
-
Industrial RF Systems: High-power RF heating, wireless industrial sensors, and microwave communication links.
