Rogers RO4534 High Frequency PCB - 20mil 30mil 60mil Antenna PCB with Immersion Gold and Immersion Tin for Cellular and WiMAX Applications
(Printed Circuit Boards are custom-made products; the images and parameters shown are for reference only.)
General Description
The Rogers RO4534 High Frequency PCB is a high-performance printed circuit board designed for antenna applications, utilizing Rogers Corporation's RO4534 laminates. This ceramic-filled, glass-reinforced hydrocarbon-based material is engineered to meet the specific demands of the antenna market. With a dielectric constant (Dk) of 3.4 and a low loss tangent (Df) of 0.0027 at 10 GHz, the RO4534 PCB allows antenna designers to achieve substantial gain while minimizing signal loss. It is an affordable alternative to traditional PTFE antenna technologies, offering an optimal balance of price and performance.
The RO4534 material's resin system is designed to provide ideal antenna performance, with coefficients of thermal expansion (CTEs) in the X and Y directions closely matching that of copper. This CTE match reduces stress in the printed circuit board, ensuring reliable performance in demanding applications. The PCB is available with immersion gold or immersion tin surface finishes, providing excellent solderability and corrosion resistance.
