Using Enhanced Load-Pull Measurements for the Design of Base Station Power Amplifiers

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 the case of two-tone load pull), in addition to the swept source or load impedances. This application note examines how to use enhanced load-pull measurements for the design of base station power amplifiers.
