3. Key Material Features & Benefits (RO4730G3):

The use of Rogers RO4730G3 material provides significant advantages for RF designs:

-Optimized RF Performance: Stable dielectric constant (Dk) of 3.00 ± 0.05 at 10 GHz and an ultra-low dissipation factor of 0.0028 for reduced insertion loss.

-Low Passive Intermodulation (PIM): Ideal for cellular base station antennas where signal integrity is critical.

-Excellent Thermal Stability: High Tg >280°C and a low Thermal Coefficient of Dk (34 ppm/°C) ensure consistent electrical performance across temperature variations.

-Ease of Fabrication: Fully compatible with standard FR-4 multi-layer processing and lead-free assembly, eliminating the need for specialized PTFE treatments.

-Lightweight & Robust: Unique filler system makes the material 30% lighter than PTFE/glass and features a CTE matched to copper for enhanced reliability.

-Environmental Compliance: RoHS compliant and compatible with lead-free soldering processes.

4. Typical Applications:

This PCB is ideally suited for:

-Cellular Base Station Antennas

-Various other RF and antenna applications requiring stable electrical performance and low loss.
