The principle and application of loadpull in a design

can anybody tell me the principle and application about Loadpull IN PA design or other RF components design fields.....

for detail, please reference the book writen by stevens cripps.
Loadpull is used find the optimum output impedence.

Hello RF_beginner,


Attached are very good documents on Loadpull Simulations using CAD tool such as AWR Microwave Office...

The following two books helps in understanding Loadpull simulations for PA applications...
