Hertz (Hz)｜Glossary
This page is part of the Electrical Glossary for RF and coaxial systems.
What Is Hertz (Hz)?
Hertz (Hz) is the unit used to measure frequency. It represents the number of cycles or repetitions of a periodic signal per second.
1 Hz corresponds to one cycle per second. Higher units such as kilohertz (kHz), megahertz (MHz), and gigahertz (GHz) are used for higher-frequency signals.
For example, 1 kHz equals 1,000 Hz, 1 MHz equals 1,000 kHz, and 1 GHz equals 1,000 MHz.
Hertz is widely used in electrical engineering, wireless communication, and RF systems to describe signal frequency.
Hertz in RF and Coaxial Systems
In RF and coaxial systems, hertz (Hz) is used to specify the frequency range of signals, components, and systems.
Different RF components such as cables, connectors, and antennas are designed to operate within specific frequency ranges, often expressed in MHz or GHz.
As frequency increases, signal loss, attenuation, and design complexity also increase, making frequency specifications critical for system performance.
Understanding frequency units is essential for selecting compatible components and ensuring proper signal transmission in RF systems.
FAQs: Hertz
QWhat is hertz (Hz)?
QWhat is hertz (Hz)?
Hertz (Hz) is the unit of frequency, representing the number of cycles per second.
QWhat is the difference between Hz, kHz, MHz, and GHz?
QWhat is the difference between Hz, kHz, MHz, and GHz?
These are frequency units where each step represents a factor of 1,000: 1 kHz = 1,000 Hz, 1 MHz = 1,000 kHz, and 1 GHz = 1,000 MHz.
QWhy are MHz and GHz commonly used in RF systems?
QWhy are MHz and GHz commonly used in RF systems?
RF systems operate at high frequencies, so MHz and GHz are used to represent these large values conveniently.
