Net Power
Net Power is defined as Forward Power minus the Reflected Power. This document describes the formula's that should be used to correctly calculate the Net Power.
Frequency [MHz] | Forward Power [dBm] | Reflected Power [dBm] |
---|---|---|
201,973 | 50 | 30 |
Question: What is the Net Power?
Answer: 49,95635195 dBm
The calculation
First you calculate the dBm values to linear values.
Formula -1: Logarithmic power value to linear power value
Subtract the linear values
Formula -2: Net power calculation from forward and reflected power
Convert the value to dBm again:
Formula -3: Linear power value to logarithmic power value
