Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies ...

The mystery of fast radio bursts (FRBs) from space may be a step closer to being solved. Astronomers studying a repeating signal from a nearby galaxy have detected radiation at the lowest frequency of ...

Laurynas Maciulis discusses Astrolight's innovations in laser communication, emphasizing its potential to transform ...

What are harmonics in RF systems? A given signal’s second harmonic is approximately twice the given signal’s fundamental frequency. Ideally, amplifiers are expected to have zero non-linearities in the ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
