Synchronized Source/Load-Pull Analysis and Communication System Measurements for Powerful PA Design
A rich set of load-pull data provides power amplifier (PA) designers with the means to investigate the optimum capability of a communication device in relation to design goals and performance targets. To fully benefit from this information, designers need an intuitive method for working with complex swept load-pull data sets.
This application note describes how load-pull data files with an independent swept parameter such as power can be used directly in NI AWR software, specifically Microwave Office circuit design software. The design of a Class J PA is used as an example to show how the load-pull data can be used to complement traditional, theoretical Class J analyses and streamline the design flow.
