These are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves, so they are used in radio technology, among other uses. Different …

Learn about electromagnetic radiation and why it is so useful for wireless communication. When we think of electricity, we naturally think of wires. From high-voltage transmission lines to tiny …

Aug 2, 2025 · When you hear “radio frequency”, think of it like a big neighborhood filled with invisible streets. Each street (or band) carries signals that let your phone call, your Wi-Fi …

What is RF? Learn the radio frequency basics and how Keysight’s tools help engineers test and optimize RF systems.

The realm of radio frequency engineering is undergoing a whirlwind transformation, propelled by groundbreaking technologies and an insatiable appetite for streamlined communication systems.

So, with a scope, we can read the phase information (in the time domain) and gather basic amplitude and frequency information in the frequency domain by using FFTs.

Radio frequency (RF) basic terms, the principle of operations, practical design, and testings are discussed. A signal frequency with greater than 300 MHz is considered RF.
