Adding attenuation to improve a load VSWR.

If you have a load with a high VSWR value, it is possible to improve the matching to the source impedance by inserting a resistive attenuator between the generator and its load. With this calculator, you can calculate the final improved VSWR value when attenuation is inserted between the source and the load impedance that initially do not have a 50 Ohm match.

The following variables can be changed in this tool:

-  Load VSWR

-  Applied attenuation

This attenuation calculator provides as output to the user the original return loss, the improved return loss and final VSWR. These results are displayed in the right-hand corner of the window in the yellow text boxes.
