Loadpull Analysis of NLAMP

For the loadpull analysis, the resistance and reactance of the load at Port 2 is varied to cover the entire Smith chart.

1. Expand the Analyses icon and double-left-click on Loadpull.

The Loadpull analysis is set to analyze the first seven harmonics of frequency freq1, with added sweeps of ZRho and ZAng, the resistance and reactance variables. Click OK to close the setup dialog.

2. With analysis Loadpull still selected, right-click and select Analyze. The analysis runs to completion.

3. Click on the Results icon and double click on loadpull Smith Contour to see the results:

The loadpull Smith Contour plot shows the output power in dBm over the swept loadings as a Smith Chart contour. The plot shows the Maximum output power generated by the amplifier for a given load impedance.
