Power amplier design using measured load pull data
One of the most popular empirical approaches for designing power ampliers is through the use of load pull/source pull measurements, which is conventionally limited to the graphical display of key performance data. This paper describes a technique for creating an accurate behavioural model within the software that avoids the need for manual entry of load pull data.
oad pull data provides accurate performance information from the actual device, which the designer can use to make informed decisions about the power amplier design. The conventional use of measured load pull data to design power ampliers is usually limited to the graphical display of important quantities such as gain, third order intercept and
