High frequency PCBs are generally used in radar systems, satellites, antennas, communication systems, power amplifiers, radio frequency identification (RFID), airborne and ground radar systems, millimeter wave applications, missile guidance systems, space satellite transceivers, instruments, automotive ADAS systems, 5G equipment and other fields.
With the rapid development of science and technology, the functions of devices are becoming more and more complex, and many devices are designed in the microwave frequency band or even beyond the millimeter wave. This also means that the frequency is constantly increasing, and the requirements for the PCB substrate are getting higher and higher. As the frequency of the power supply signal increases, the loss of PCB materials is very small, so the importance of high-frequency PCB boards is highlighted.
