High-Performance RO4533 2-Layer PCB with 0.6mm Thickness for Antenna Applications

1.Introduction

Rogers RO4533 laminates are ceramic-filled, glass-reinforced hydrocarbon-based materials designed for superior RF performance in microstrip antenna applications. These laminates offer controlled dielectric constant, low loss, and excellent passive intermodulation (PIM) response, making them ideal for mobile infrastructure and WiMAX antenna networks.

Fully compatible with conventional FR-4 and lead-free soldering processes, RO4533 eliminates the need for special treatments required by traditional PTFE-based laminates. Its cost-effective design balances performance and affordability while meeting stringent environmental standards with halogen-free options.

The material's excellent thermal properties—including a CTE closely matched to copper and a high glass transition temperature (Tg >280°C)—ensure reliability in demanding environments. With low moisture absorption (0.02%) and high thermal conductivity (0.6 W/mK), RO4533 PCBs deliver stable performance in high-power applications.
