Net Power defined as Forward Power minus the Reflected Power This document describes how you should calculate the Net Power correctly.
Frequency (MHz) | Forward Power (dBm) | Reflected Power (dBm) |
---|---|---|
201,973 | 50 | 30 |
Question: What is the Net Power?
Answer: 49,95635195 dBm
The calculation[edit]
First you calculate the dBm values to linear values.
Subtract the linear values
Convert the value to dBm again:
