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.

Understanding VSWR and Return Loss

Introduction

This guide explains VSWR (Voltage Standing Wave Ratio) and Return Loss in RF systems.

What are VSWR and Return Loss?

• VSWR (Voltage Standing Wave Ratio): A measure of how well an antenna or load is matched to a transmission line. A VSWR of 1:1 is a perfect match, while a higher VSWR indicates a mismatch.

• Return Loss: A measure of the power reflected back from an antenna or load. A higher return loss indicates a better match.

Deep Dive into ERP/EIRP Calculations

Introduction

This guide explains how to calculate Effective Radiated Power (ERP) and Effective Isotropic Radiated Power (EIRP).

What are ERP and EIRP?

• ERP (Effective Radiated Power):
  The amount of power that an antenna radiates, taking into account the antenna gain and cable loss.

• EIRP (Effective Isotropic Radiated Power):
  The amount of power that an antenna would radiate if it were an isotropic antenna (an antenna that radiates power equally in all directions).

Understanding RF Power Units and Conversions

Introduction

This guide explains the different RF power units and how to convert between them.

Common RF Power Units

• Watt (W):
  The standard unit of power, representing the rate at which energy is transferred.

• dBm:
  A logarithmic unit of power relative to 1 milliwatt (mW).

• dBW:
  A logarithmic unit of power relative to 1 watt (W).

RF Power Conversions

• Watts to dBm:
  dBm = 10 * log10(Power in Watts * 1000)
