DiClad 527 Material Overview
Rogers DiClad 527 is a high-performance woven fiberglass-reinforced PTFE composite substrate specially developed for high-frequency PCB manufacturing. Featuring a precisely calibrated fiberglass-to-PTFE proportion, this material delivers a stable dielectric constant and superior dimensional stability when compared with traditional PTFE substrates. Its refined structural composition ensures accurate circuit registration and consistent electrical performance for advanced high-frequency circuit designs.
Core Material Performance Features
1. Stable Low-Loss Dielectric Properties
It maintains a stable dielectric constant ranging from 2.4 to 2.6 at both 1 MHz and 10 GHz, paired with an ultra-low dissipation factor of 0.0017 at 10 GHz, effectively minimizing high-frequency signal attenuation and phase distortion.
2. Reliable Thermal Dielectric Stability
The material exhibits a steady thermal coefficient of dielectric constant at -153 ppm/°C across a wide temperature range from -10°C to 140°C, sustaining stable dielectric performance under fluctuating thermal environments.
3. Excellent Structural Stability
Its well-matched coefficient of thermal expansion delivers balanced thermal expansion characteristics, which significantly reduces thermal stress and structural deformation during temperature cycling, ensuring outstanding long-term mechanical reliability.
4. Superior Environmental Adaptability
Boasting an ultra-low moisture absorption rate of 0.03%, the material generates negligible performance variation in high-humidity conditions, while its excellent chemical resistance enables reliable operation in harsh and complex working environments.
Typical Application Scenarios
Supported by ultra-low high-frequency loss, exceptional dimensional stability, uniform electrical characteristics and reliable environmental adaptability, DiClad 527 PCBs are extensively adopted in high-precision RF and microwave systems for various professional applications, as listed below:
-Radar feed networks and guidance systems
-Commercial phased array network equipment
-Low-loss base station antennas and digital radio antennas
-High-performance RF filters, couplers and LNA modules
