Will 5g have requirements for PCB materials?

Author:admin   AddTime:2020-08-04

What is 5g? 5g is the abbreviation of the fifth generation wireless communication technology, and communication technology can be divided into wired communication and wireless communication. Cable communication refers to the transmission of information and data on the physical matter, which is basically the wired media such as copper wire and optical fiber.

In the cable medium propagation, the rate can reach very high. Taking optical fiber as an example, the maximum speed of a single fiber has reached 26tbps in the laboratory. This is a terrible figure. Compared with the current mainstream 4G LTE theory of 150Mbps (without carrier aggregation and other technologies), the gap is enormous.



5g has brought us some interesting challenges. If we look at it from the perspective of PCB materials, there are not many changes from 2G to 3G to 4G. Of course, many other technologies are also developing rapidly, but in the circuit board industry, the demand for materials has not changed a lot. The reason is very simple, from the hardware point of view, the frequency has only changed a little - 700MHz, 900MHz, increased from 1.8 to 2.5, and so on. Power amplifiers and antennas are still the same.



As most people know, 5g is interesting because it's divided into two areas; the larger one (at least initially) is a market smaller than 6GHz. Another area is millimeter wave, which has a frequency of 28ghz. Because the frequency of millimeter wave is very high, the requirement of material has been changed greatly. The material must be low loss.
