Electrical engineering students rarely leave college with knowledge depth in both digital electronics and RF/microwave theory. The new engineer with digital design skills likely chose that path from a ...

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 ...

In the late 1800s a German physicist named Heinrich Hertz created radio waves in the laboratory. A century later, we are still expanding upon Hertz’s discovery. Radio waves make possible all wireless ...
