title = "High-speed device characterization using an active load-pull system and waveform engineering postulator",
abstract = "This paper presents a methodology that provides rapid estimation of the parameters necessary for the high-speed characterization of transistor devices used in modern microwave power amplifiers. The key in achieving this significant measurement speed improvement is the use of a systematic waveform postulation methodology in combination with an active harmonic load-pull measurement system. The methodology is based on a rapid and systematic procedure that initially requires only a few DC measurement parameters to approximate the device's transfer characteristic and boundary conditions. Using these parameters, it is then possible to accurately estimate or postulate the idealized output current and voltage waveforms, in this case for a three harmonic Class-F mode. These waveforms are rich in information and provide harmonic load impedances as well as other key postulated parameters that can then be used to guide the harmonic active load-pull measurement system resulting in a very time-efficient characterization process.",
