RF PCB Design Solutions: A Professional Platform Empowering High-Frequency Applications

Core Challenges and Value of High-Frequency Circuit Design

In fields such as wireless communication, sistemi radar, navigazione satellitare, and 5G/6G devices, RF PCB design is the core technology that determines signal integrity, power transmission efficiency, and system reliability. The primary challenges include:

• High-Frequency Signal Loss Control: Skin effect, dielectric loss, and impedance mismatch become significant at GHz frequencies.
• Electromagnetic Compatibility (EMC) Optimization: Reducing crosstalk and radiation to meet stringent certification standards like FCC and CE.
• 3D Electromagnetic Field Co-Design: Addressing field distribution optimization for transmission line structures such as microstrips and coplanar waveguides.
• Thermal-Mechanical-Electrical Multi-Physics Coupling: Balancing heat dissipation and mechanical stability in high-power scenarios.

As a core competency, UGPCB is committed to helping clients achieve key performance indicators such as insertion loss ≤0.3dB/inch (@28GHz), VSWR <1.5, and phase consistency of ±2° through full-process simulation verification and process innovation.
