Precision-Engineered RF PCB for Demanding High-Frequency Applications
The RO3200 0.8mm 1oz Hard Gold 2-Layer High-Frequency Filter PCB from PCBSync delivers exceptional electrical performance and mechanical reliability for engineers designing at the cutting edge of RF, microwave, and millimeter-wave systems. Built on Rogers RO3200-series laminate — a woven-glass-reinforced, ceramic-filled PTFE composite — this board is purpose-built for filter circuits, antenna feed networks, and other signal-critical applications where dielectric stability and low loss are non-negotiable.

Why Choose RO3200 Laminate?
Rogers RO3200 materials offer a stable dielectric constant across a wide frequency range, ultra-low loss tangent, and predictable impedance characteristics — essential for designing band-pass, low-pass, and notch filters used in telecommunications, aerospace, and industrial sensing. Compared with standard FR-4, RO3200 provides dramatically lower insertion loss, tighter Dk tolerances, and superior thermal stability, allowing your filter to perform consistently from microwave through mmWave bands. The woven-glass reinforcement also delivers improved dimensional stability over pure PTFE substrates, simplifying multilayer alignment and reducing fabrication risk.
Hard Gold Surface Finish — Built for Longevity
The Hard Gold plating used on this PCB is ideal for connector pads, edge fingers, and contact zones that must withstand repeated insertion or wear cycles. Unlike soft immersion gold (ENIG), hard gold contains a small percentage of cobalt or nickel for added abrasion resistance, ensuring long-term contact integrity in mission-critical RF assemblies. It also offers excellent corrosion protection and reliable solderability across the wirebond and SMT process windows.
