In this series, I'm going to show you some very simple rules to achieve the highest performance from your radio frequency PCB design for your electronics project. I'll do this by showing you how to improve the grounding and reduce the crosstalk. These rules apply to both analog , digital and RF electronics. I'll also share some rules of thumb for PCB parasitics that you can use in electronics simulations. I'll prove my points with actual measurements on dedicated test PCBs. In this first part, I'll focus on why ground planes are so effective.
