4.2 Reference Design for RF Layout
For the RF part of a PCB, ensure that the characteristic impedance of the RF line is 50 ohms.
The impedance of an RF line is generally determined by the line width (W), dielectric constant
of the material, distance away from the reference signal layer (H), and gap between the RF
