Radio Frequency engineering is one of those fields that humbles even experienced engineers. Once you reach frequencies above a few hundred MHz, the rules change rapidly. Traces stop behaving like wires, impedance becomes a moving target, and your PCB layout quietly decides the fate of your entire design. This article, the first in a multi-part series on “Mastering RF Engineering,” by Mouser Electronics, explores how RF technology is designed, built, and tested, highlighting the principles, compo

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

Radio frequency tech is everywhere, from the phones in our pockets to the satellites above us. Spanning from mere kilohertz to tens of terahertz, the RF spectrum powers communication, sensing, navigation, and even the unglamorous but essential tools that heat, seal, and sanitize products worldwide. Because RF applications are so diverse, the expertise required is just as broad. Together with Mouser Electronics, we have launched a new series titled “Mastering RF Engineering”. The series examines
