Radio frequency (RF) PCB design , published in the current theoretically have a lot of uncertainty , often described as a " black art ." Typically, the following circuit for the microwave band ( including low frequency and low-frequency digital circuits ) , in complete control of all types of design principles is the premise of careful planning to ensure the success of one-off designs. For microwave and high frequency bands above the PC class digital circuits , you will need two to three versions of the PCB circuit can ensure quality .
