single-ended network in the design is generally controlled by 50 ohms, so many people will ask, why is it required to be controlled by 50 ohms instead of 25 ohms or 80 ohms? First of all, 50 ohms is selected by default, and everyone in the industry accepts this value. Generally speaking, it must be a standard set by a recognized organization, and everyone designs according to the standard.
