What is the Received Power Density Calculator? 

Received Power Density Calculator is an online tool that helps to calculate Received Power Density when the user enters the value of signal strength (dBm), antenna factor (dB/m), cable loss (dB), and pre-amplifier gain (dB). This calculator uses the following formula, and the calculation is based on the system impedance of Z= 50 ohms, far-field measurement, and Free-space conditions (impedance of 377 ohm). 

• Where, 

  dBm - Signal strength (dBm) 

  AF - Antenna factor (dB/m) 

  CL- cable loss (dB) 

  G - Pre-amplifier gain (dB). 

  Power density calculation is necessary when: 

• Estimating electromagnetic interference (EMI) effect.  
  
• Assessing potential radiation hazards (personnel safety and RF exposure). 
• Measuring or verifying specifications.
