The Arlon PCB CLTE-XT low Df PCB is a high-performance, microglass-reinforced PTFE substrate designed specifically for high-frequency RF and millimetre-wave (mmWave) circuit applications. Engineered for critical electronic systems, this laminate addresses the strict electrical and mechanical demands of aerospace, defense, and 5G telecommunications infrastructure. It provides engineering teams with the phase stability and low insertion loss required to maintain signal integrity at extreme operational frequencies.

• Ultra-Low Loss Tangent: A dissipation factor (Df) of 0.0025 at 10 GHz minimizes signal attenuation and dielectric loss in high-frequency paths.

• Stable Dielectric Constant: Maintains a controlled Dk of 3.00 ($\pm$ 0.04) across a wide temperature range, ensuring predictable impedance matching.

• Thermal Phase Stability: Low electrical phase change with temperature variance protects signal consistency in outdoor and high-heat environments.

• Excellent Dimensional Stability: Microglass reinforcement yields a low X/Y axis CTE (Coefficient of Thermal Expansion), making it highly reliable for complex multi-layer registration and fine-line circuitry.

• IPC Compliance: Fabricated in strict accordance with IPC-4103 standards for high-speed, high-frequency base materials.

• mmWave Radar Systems: Used extensively in automotive ADAS (Advanced Driver Assistance Systems) radar modules operating at 77 GHz and 79 GHz.

• 5G/6G Infrastructure: Ideal for base station antennas, power amplifiers, and MIMO (Multiple-Input Multiple-Output) antenna arrays.

• Satellite Communications: Deployed in space-borne transponders, VSAT terminals, and ground station RF front-ends.

• Aerospace & Defence: Integrated into electronic warfare (EW) systems, missile guidance modules, and phased-array radar systems.
