Attenuation｜Glossary
This page is part of the Electrical Glossary for RF and coaxial systems.
What Is Attenuation?
Attenuation is the reduction in signal strength as it travels through a medium such as a cable or transmission line.
It represents the loss of signal amplitude due to factors like resistance, dielectric loss, and radiation.
Attenuation is typically expressed in decibels (dB), indicating how much signal power is reduced.
It is a key parameter in evaluating signal transmission performance in electrical and RF systems.
Attenuation in RF and Coaxial Systems
In RF and coaxial systems, attenuation increases with both cable length and operating frequency.
Longer cables result in greater signal loss, and higher frequencies experience more attenuation due to skin effect and dielectric losses.
Cable type, conductor size, and material quality all influence attenuation performance.
To minimize attenuation, low-loss cables, proper cable selection, and optimized system design are essential.
Managing attenuation is critical for maintaining signal integrity and ensuring reliable communication in RF applications.
