The high frequency of electronic devices is a development trend, especially with the increasing development of wireless networks and satellite communication. Information products are moving towards high speed and high frequency, and communication products are moving towards standardized wireless transmission of voice, video, and data with large capacity and high speed. Therefore, the new generation of products that are developed require high-frequency circuit boards.

Choosing PCB boards must strike a balance between meeting design requirements, mass production feasibility, and cost. Simply put, design requirements include two parts: electrical and structural reliability. This board issue is usually more important when designing very high-speed PCB boards (frequencies greater than GHz). For example, the commonly used material FR4 may not be suitable due to its high dielectric loss Df at frequencies of several GHz.

How to choose Rogers high-frequency high-speed sheet metal

In practical engineering operations, the selection of high-frequency boards may seem simple, but there are still many factors to consider. Through the introduction in this article, as an engineer or high-speed project leader, I have a certain understanding of the characteristics and selection of boards. Understand the electrical, thermal, and reliability properties of the sheet metal. And use layering reasonably to design a product with high reliability and good processability, taking into account various factors to achieve optimization.

The RT5880 high-frequency board is made of polytetrafluoroethylene glass fiber reinforced material. High frequency circuit design has always had strict requirements for the dielectric constant of printed circuit boards. The dielectric constant of RT5880, measured at a working frequency of 10GHz, is only 2.2, which is significantly lower than similar materials currently on the market. Therefore, from the perspective of performance parameters and production costs, this board is more suitable for high-frequency design applications compared to similar products. At the same time, the dielectric loss of the board, measured under the same standard, is only 0.0009. The extremely low dielectric loss makes it very suitable for high-frequency and wideband design applications that require minimal dispersion and loss. It is mainly used for point-to-point digital radio antennas, microstrip and strip line circuits, millimeter wave applications, missile guidance systems, military radar systems, and high-frequency circuit boards for commercial aviation telephones.
Characteristics of RT5880 high-frequency board:
1. Extremely low dielectric constant, measured at 10GHz, with a dielectric constant of 2.20 ± 0.02;
2. Extremely low dielectric loss, measured at 10GHz, with a dielectric loss factor of 0.0009;
