Cable Attenuation Explained

Introduction

This guide explains cable attenuation in RF systems and how to calculate it.

What is Cable Attenuation?

• Cable attenuation is the reduction in signal strength as it travels through a cable.
• It is typically measured in decibels per unit length (dB/m or dB/ft).

Factors Affecting Cable Attenuation

• Cable Type:
  Different cable types have different attenuation characteristics.

• Frequency:
  Attenuation increases with frequency.

• Cable Length:
  Attenuation increases with cable length.

• Temperature:
  Attenuation can also be affected by temperature.

How to Calculate Cable Attenuation

• Total Attenuation (dB) = Attenuation per unit length (dB/m) * Cable Length (m)

Why is Cable Attenuation Important?

• It affects the signal strength at the receiver.
• It can limit the range of a wireless system.
• It needs to be taken into account when designing RF systems.
