"Designing with Enhanced Load Pull Measurements for Base Station Power Amplifiers" is a new application
note that describes how to use the advanced load-pull features in NI AWR Design Environment™ to design matching networks and associated circuitry directly from measured
load-pull data. Load pull has been used for decades in RF circuit design flows, especially for high-power applications such
as base station power amplifiers (PAs). Recent advances in data file formats by load-pull measurement system vendors have
significantly expanded the usefulness of load-pull characterization. These new file formats support a sweep of an independent
variable such as input power, DC bias, temperature, or tone spacing, in addition to the swept source or load impedances.
The ability to import and manipulate these load-pull data sets in a circuit simulator greatly simplifies and speeds the
design process, and gives designers a broader design space to explore.
