What is High-Frequency PCB

High-frequency PCBs generally provide a frequency range of 500MHz to 2 GHz, which can meet the needs of high-speed PCB design, microwave, radiofrequency and mobile applications. When the frequency is higher than 1 GHz, we can define it as high frequency.

Today, the complexity of electronic components and switches keeps increasing, and a faster signal flow is required than usual. Therefore, a higher transmission frequency is required. When integrating special signal requirements into electronic components and products, high-frequency PCB has many advantages, such as high efficiency, fast speed, low attenuation, and constant dielectric constant.

High-frequency PCB characteristics

1. DK should be small and stable, most of the time the smaller the better, the high DK may cause signal transmission delay. 
2. DF should be small, whose size mainly affects the quality of signal transmission. The smaller the DF, the less the signal loss. 
3. The thermal expansion coefficient should be the same as the copper foil as much as possible because the difference will cause the copper foil to separate in the cold and heat changes.
4. The water absorption rate must be low. In a humid environment, a high water absorption rate will affect DK and DF. 
5. Heat resistance, chemical resistance, impact resistance, and peel resistance must be good.
 

High-frequency PCB - special materials

Special materials are needed to realize the high frequency provided by this type of printed circuit board, Because any change of their permittivity may affect the impedance of the PCBs. Many PCB designers choose Rogers dielectric material because it has lower dielectric loss, lower signal loss, lower circuit manufacturing costs, and is more suitable for rapid turnaround prototype applications among other materials.
