High frequency board refers to the high frequency circuit board which carry high frequency signal. High frequency signal can be defined as the frequency above 1GHz.It's more expensive than nomarl PCB. High frequency board are made of low dielectric constant, low high-frequency loss material. Currently most high-frequency board substrate is fluorine resin, such as polytetrafluoroethylene (PTFE), usually called Teflon, usually used in more than 5GHz situation.
