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

This is the final article in our Mastering RF Engineering series, published in partnership with Mouser Electronics. The series explores how RF systems are designed, built, and tested, guiding readers from core principles to real-world applications in modern wireless technology. Because RF engineering demands extreme precision, robust test and measurement systems are essential throughout development, deployment, and maintenance. These tools ensure reliable performance, ongoing calibration, and co

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
