What is a high-frequency PCB board? What are the high-frequency boards? How to choose?
High-frequency circuit board refers to a special circuit board with a higher electromagnetic frequency. It is used in the fields of high frequency (frequency greater than 300MHZ or wavelength less than 1 meter) and microwave (frequency greater than 3GHZ or wavelength less than 0.1 meter). It is a circuit board produced by using some processes…
