This guide delves into the four fundamental characteristics of RF circuits—RF interface, small desired signals, large interference signals, and adjacent channel interference—and highlights essential considerations for PCB design.
Printed Circuit Boards (PCBs) are the foundation of most electronic devices. The PCB production process can be categorized into subtractive methods and additive methods. Currently, the most commonly used industrial method is the copper foil etching process, a subtractive method.
