What is High Frequency PCB? Just as its name implies, high frequency is that the frequency is relatively high, generally refers to the frequency of >=300 MHz (i.e. wave length <=1m), that is, the usual radio frequency band. The electromagnetic wave of frequency >=1GHz is called microwave. Typical frequencies for wireless applications: * Current mobile: 0.9GHz - 2GHz * 3G systems: 2.5GHz *...
