Rf signal

When RF and microwave enter the layout, the PCB designer must have the same mindset, yet multiply that mindset many times simply because RF is far more sensitive than very high-speed digital signals. Second, impedance matching is extremely critical for RF. Digital signals — even if they are very high-speed — have a certain tolerance.
