Material Advantage: The RO4725JXR Core

At the heart of this PCB lies Rogers RO4725JXR, a hydrocarbon/ceramic/woven glass laminate that sets a new standard for cost-effective, high-performance antenna-grade materials. It serves as a reliable, drop-in alternative to conventional PTFE-based laminates, fully compatible with standard FR-4 and lead-free assembly processes without requiring special through-hole treatments.

Its exceptional electrical properties are the foundation of its performance:

1) Stable Dielectric Constant (Dk): 2.55±0.05 @ 10GHz, ensuring predictable impedance control and phase stability.

2) Ultra-Low Loss Tangent (Df): As low as 0.0022 @ 2.5GHz, which minimizes signal attenuation and insertion loss, crucial for antenna gain and efficiency.

3) Excellent Thermal Coefficient of Dk: +34 ppm/°C, guaranteeing consistent electrical performance across operating temperature ranges.

4) Copper-Matched CTE: (13.9/19/25.6 ppm/°C in X/Y/Z axes) reduces the risk of plated through-hole reliability issues under thermal cycling.

5) High Thermal Reliability: Tg >280°C ensures robustness during high-temperature assembly and operation.

6) Superior Passive Intermodulation (PIM) Performance: Typical values better than -160 dBc, with perfect PIM as low as -166 dBc, making it ideal for multi-carrier, high-power antenna systems where signal purity is critical.
