Frequency｜Glossary
This page is part of the Electrical Glossary for RF and coaxial systems.
What Is Frequency?
Frequency is the number of times a periodic signal repeats per second. It represents how often a waveform cycles and is a fundamental parameter in electrical and RF systems.
Frequency is measured in hertz (Hz), where 1 Hz equals one cycle per second.
It is a key characteristic of electrical signals, including AC power, radio waves, and digital communication systems.
Higher frequencies correspond to shorter wavelengths and faster signal variations, which significantly influence signal behavior and system design.
Frequency in RF and Coaxial Systems
In RF and coaxial systems, frequency is a critical factor that determines signal behavior, transmission characteristics, and component performance.
As frequency increases, effects such as attenuation, skin effect, and signal loss become more pronounced in cables and connectors.
Impedance matching becomes more sensitive at higher frequencies, and even small discontinuities can cause reflections and signal degradation.
Frequency also determines the wavelength of signals, which affects antenna design, cable length considerations, and system layout.
Understanding frequency is essential for optimizing signal transmission, minimizing loss, and ensuring reliable RF system performance.
