Rogers RO4533 2-Layer 30mil Antenna PCB: Low-Loss High-Stability Solution With ENEPIG Surface Finish
Printed Circuit Boards are custom-made products; the images and specifications provided are for reference only.
1. Introduction to Rogers RO4533 PCB
Rogers RO4533 2-layer PCB is built on ceramic-filled, glass-reinforced hydrocarbon laminates, engineered to deliver controlled dielectric constant, low-loss performance, and exceptional passive intermodulation (PIM) response—key requirements for mobile infrastructure microstrip antenna applications. Fully compatible with conventional FR-4 processing and high-temperature lead-free soldering protocols, this PCB eliminates the need for the special surface treatments required by traditional PTFE-based laminates during plated through-hole (PTH) preparation. As a cost-effective alternative to standard PTFE antenna technologies, Rogers RO4533 PCB enables designers to strike the perfect balance between performance and affordability for antenna designs. What’s more, it is available in halogen-free formulations to meet the most stringent global “green” manufacturing standards.
The dielectric resin system of Rogers RO4533 PCB board is optimized for ideal antenna performance. Its X and Y-axis coefficients of thermal expansion (CTEs) closely match that of copper, minimizing thermal stresses in printed circuit board antennas and enhancing long-term reliability. With a glass transition temperature (Tg) exceeding 280°C (536°F), the PCB boasts a low Z-axis CTE and outstanding PTH reliability, ensuring consistent performance even under harsh operating conditions.
