VSWR, Return Loss & Reflection
VSWR to Reflected Power Calculator
Find how much of the forward power a given VSWR sends back to the amplifier, as a percentage and in watts.
Result
Enter the inputs above and select Calculate.
Formula: P_ref = P_fwd · ((VSWR − 1) / (VSWR + 1))²
The reflected power is what the amplifier's output stage and circulator load have to absorb.
