Frequency range: Generally speaking, high-frequency boards can be defined as PCBs with a frequency above 1GHz. They are mainly used in PCBs 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 mete
High-frequency PCB is a special circuit board with a higher electromagnetic frequency, which is above 1GHz. The physical properties, precision and technical parameters of high-frequency PCB are very high, and it is often used in radar, military equipment, aerospace and other fields.
