Return loss (RL) and Voltage Standing Wave Ratio (VSWR) are both measurements used to quantify efficiency of power transfer in radio frequency (RF) and Microwave systems. They are related but represent same information in different ways. Return Loss in dB: It is a measure of reflected power ...

VSWR (Voltage Standing Wave Ratio)is the measure of how efficiently RF power is transmitted and is expressed as a ratio of the maximum to minimum amplitude (or the voltage or current) of the corresponding field components appearing on a line that feeds an antenna. Return Lossis a amount of ...
When the line is longer, we don’t have return loss resonance problems with high VSWR and radiation, but can we still have the same mismatch regardless. Although longer lines do not have the same return loss resonance problems as shorter lines, the channel is now dominated by S21 or inserti...
Now we can explore how much return loss will begin to affect insertion loss, the signal at the transmitter. We usually measure S11and SS21in decibels. Thus, we need to convert the decibel value into a magnitude, do the calculation, then convert the SS21magnitude value back into decibels. ...
