RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

"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.
