The Arlon Microwave PCB CLTE 4-Layer Ku-Band Filter Board is engineered for high-frequency RF systems requiring minimal signal loss and exceptional dimensional stability. Built on a ceramic-filled, PTFE-based woven fiberglass substrate, this multilayer board provides a tightly controlled dielectric constant (DK 2.94) across a wide temperature range. It is ideal for defence, aerospace, and telecommunications applications where phase stability and phase tracking are critical to system performance.
Key Features
-
Substrate Material: Genuine Arlon CLTE (ceramic-filled PTFE / woven fiberglass).
-
Dielectric Constant (DK): Tightly controlled at 2.94 (±0.04) at 10 GHz for precise impedance matching.
-
Layer Count & Frequency: 4-layer stack-up optimised for Ku-band (12 GHz to 18 GHz) filter configurations.
-
Dissipation Factor (DF): Ultra-low loss tangent of 0.0025 at 10 GHz to maximise signal strength.
-
Thermal Expansion: Low CTE ($z\text{-axis} = 34\text{ ppm/}^\circ\text{C}$) ensuring reliable plated through-hole (PTH) reliability in harsh environments.
-
Surface Finish: Electroless Nickel Immersion Gold (ENIG) for superior solderability and oxidation resistance.
Applications
-
Ku-band satellite communication (Satcom) terminals and transceivers.
-
Military and commercial radar systems requiring phase-matched performance.
-
Electronic warfare (EW) and signal intelligence components.
-
High-speed digital and microwave filter networks.
