In the field of PCB materials, "high-frequency and high-speed laminates" are often mentioned together. However, delving into their design cores, the two have different emphases on key indicators such as common thickness, copper foil roughness, thickness tolerance, and dielectric constant (Dk) stability. This also leads to differences in the supplier ecosystems for high-speed laminates and high-frequency laminates. Much publicly available information is currently outdated or still conflates the two. This article will focus on the 2025 market, systematically梳理ing PCB laminates specifically designed for high-frequency/radio frequency (RF)/microwave applications, and clarifying mainstream suppliers and their core products.

From the perspective of base materials, high-frequency laminates are mainly divided into two major systems:

Polytetrafluoroethylene (PTFE)-based laminates: Renowned for their extremely low dielectric loss (Df), they are the classic choice for applications at extremely high frequencies such as millimeter wave.

Hydrocarbon resin-based laminates: They achieve an excellent balance among performance, processability, and cost, and are widely used in mainstream RF products.

It is worth noting that thermoset substrates based primarily on polyphenylene oxide (PPO/PPE) resin are typically categorized as high-speed digital application laminates. However, with the evolution of material formulations, some manufacturers have also launched high-frequency laminate products based on PPO resin, broadening the material selection boundaries.

4. Panasonic

As a giant in electronic materials, Panasonic's "Megtron" series is famous for high-speed digital applications. However, its high-end models (e.g., Megtron 6/M6) are often used in high-speed 10-25G designs due to their extremely low loss factor. They are also suitable for high-frequency RF modules or mixed-signal designs sensitive to loss, and are often regarded as high-performance options by engineers.

III. Selection Summary

The selection of high-frequency laminates requires comprehensive consideration based on specific application frequency, loss requirements, power handling, cost budget, and processing technology, among other factors. The current market landscape shows a trend where international brands lead in technology, while domestic brands are catching up rapidly with outstanding cost-effectiveness. With the vigorous development of industries such as 5G-Advanced, millimeter-wave communication, satellite internet, and automotive radar, the high-frequency laminate market will continue to evolve, providing engineers with richer and more specialized material choices. For critical projects, it is recommended to communicate in-depth with the technical support teams of material suppliers and conduct sufficient laminate evaluation and process validation.
