Converting Between Microwave Parameters

Converting Between Microwave Parameters

Use this command to convert between the following common values:

• Mismatch loss in dB

• Reflection coefficient

• Return loss in dB

• Voltage standing wave ratio (VSWR)

To convert between the common microwave parameter values listed above:

1. Select the microwave parameter you want to convert - Mismatch Loss (dB), Return Loss (dB), Reflection Coefficient, or Standing Wave Ratio. Mismatch Loss (dB) is selected by default.

A value input box appears to the right, corresponding to the selected parameter.

2. Enter a value for the selected parameter in the value input box.

3. Click Calculate to calculate the equivalent values for the other three parameters.

The following equations are used when converting:

where

• RL is the return loss.

• RLdB is the return loss in dB.

The equivalent values for the other three parameters appear below in the Estimate Results area of the Estimate module.
