High-frequency circuit boards refer to special circuit boards with higher electromagnetic frequencies, and are one of the most difficult boards
Radio frequency (RF) and microwave (MW) circuits can be found in countless wireless products, from handheld devices used in medical and industrial applications to advanced communications systems used in base stations, radar and global positioning. The success of these high-speed products begins during the product design phase when selecting PCB laminate materials
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
