摘要

This article describes an alternative which overcomes the drawbacks of the existing state of the art source-and load-pull techniques with respect to speed. Also the proper integration of this data into simulators is addressed, both with respect to ease and accuracy. First, a real-time alternative for fundamental load-pull measurements is described, which is based on smart active injection. Using a large-signal network analyzer, both the fundamental and harmonic behaviour of the component can be observed separately under varying load conditions. As verification, the resulting power delivered to the load at the fundamental is compared to the one obtained using a classical load-pull technique. Next, it is demonstrated that, for a specified load, one can quickly provide fundamental source-pull information for a range of available input powers by performing a single input power sweep using a regular synthesizer. A prematch tuner can be used to overcome power limitations of the source. Again, as verification, the resulting source-pull data is compared to the one obtained using a classical source-pull technique.
