03 Radio Frequency RF Fundamentals

Modern RF (Radio Frequency) systems rely on precise circuit fabrication and interconnects to deliver reliable high-frequency performance. Used in applications such as wireless communication, radar, and sensing, RF circuits must preserve signal quality and minimize signal loss. RF components are built and connected in different ways depending on system needs. Most RF systems use planar circuit boards, which are linked to other circuits through RF interconnects such as waveguides, coaxial connecto
