1. High Dielectric Constant for Miniaturized Designs
-
Dielectric Constant (Dk): ~10.2 – stable across a wide frequency range.
-
Benefit: Enables significant circuit miniaturization, allowing compact filter layouts without compromising performance. This is essential for modern wireless systems, satellite communications, and space-constrained applications where every millimeter counts.
2. Ultra-Low Loss Tangent for Superior Signal Integrity
-
Dissipation Factor (Df): ~0.0023 at 10 GHz – extremely low signal loss.
-
Benefit: Ensures maximum power transfer and minimal insertion loss in high-frequency band-pass filters. This low-loss performance is critical for applications such as radar systems, 5G wireless infrastructure, and aerospace communications.
3. Outstanding Thermal Stability
-
Thermal Coefficient of Dielectric Constant (TCDk): Low – stable dielectric properties over a wide temperature range.
-
Benefit: Guarantees consistent filter performance under extreme environmental conditions, including high-altitude aerospace environments, automotive radar systems exposed to temperature variations, and defense applications with demanding thermal requirements.
4. Exceptional Dimensional and Mechanical Stability
-
Mechanical Properties: Low shrinkage and expansion during manufacturing and operation.
-
Benefit: Maintains precise filter dimensions and tight tolerances, reducing the risk of detuning and ensuring predictable performance. Ideal for high-precision band-pass filters used in mission-critical applications.
5. Minimal Moisture Absorption
