Rogers RO4533 30mil High Frequency Laminates PCB with Immersion Silver

Rogers RO4533 30mil High Frequency Laminates PCB with Immersion Silver

Introduction

Rogers RO4533 laminates represent a breakthrough in antenna-grade materials, offering exceptional performance and reliability for mobile infrastructure microstrip antenna applications. These ceramic-filled, glass-reinforced hydrocarbon laminates provide controlled dielectric constant, low loss performance, and outstanding passive intermodulation (PIM) response. With their compatibility with conventional FR-4 and high-temperature lead-free solder processing, they offer a cost-effective alternative to traditional PTFE antenna technologies while allowing designers to optimize antenna price and performance.RO4533 30mil laminates are also available in halogen-free variants, meeting the most stringent "green" standards.

Features

The RO4533 high frequency laminates boast an impressive set of features that contribute to their superior performance:

1)Dielectric Constant (DK) of 3.3 at 10GHz:

The controlled dielectric constant ensures consistent electrical performance, enabling designers to achieve precise antenna characteristics.

2)Dissipation Factor (DF) of 0.0025 at 10GHz:

The low loss tangent minimizes signal loss, resulting in improved overall antenna efficiency.

3)Coefficients of Thermal Expansion (CTEs): 

The X and Y direction CTEs, similar to that of copper, reduce stresses in the printed circuit board antenna, enhancing its reliability and lifespan. The Z-axis CTE is also low, ensuring excellent plated through-hole reliability.

4)Glass Transition Temperature (Tg) exceeding 280°C (536°F):

The high Tg value contributes to the low z-axis CTE and provides exceptional dimensional stability, even in extreme temperature environments.

5)Low Moisture Absorption:

With a moisture absorption rate of only 0.02%, the RO4533 laminates maintain their electrical and mechanical properties, ensuring consistent performance over time.

6)Thermal Conductivity of 0.6 W/mK:

The high thermal conductivity of RO4533 laminates allows for improved power handling capability, making them suitable for high-power antenna applications.

Benefits

RO4533 PCBs offer a range of benefits that make them an ideal choice for antenna design:

1)Low Loss, Low Dk, and Low PIM Response:

These low loss laminates deliver excellent electrical properties, resulting in minimal signal loss, precise antenna performance, and reduced intermodulation distortion.

2)Compatibility with Standard PCB Fabrication:

The thermoset resin system of RO4533 laminates is fully compatible with standard PCB fabrication processes, simplifying integration into existing manufacturing workflows.

3)Excellent Dimensional Stability:

The laminates exhibit exceptional dimensional stability, ensuring greater yield on larger panel sizes and maintaining mechanical form during handling and assembly.

4)Uniform Mechanical Properties:

The laminates offer uniform mechanical properties, providing consistent performance across the entire antenna structure.

5)High Thermal Conductivity:

The enhanced thermal conductivity of RO4533PCBs enables improved power handling, reducing the risk of overheating and ensuring reliable operation.
