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

In 1978, this TV-radio was the height of capsule technology. Now every app on your phone encapsulates an additional device we no longer need. Here's a nod to the dawning of a technological mega-trend. | Interesting Engineering
