Like an orchestra conductor, it coordinates the timing of the power amplifier, antenna, and other components. This article shares a real debugging case: when communication range fell short of spec, the interference source turned out to be the switching frequency of a DC-DC converter. It explores the challenge of signal and noise coexisting on the same board, and how to track down this kind of hidden coupled interference."}
