Measurement of the influence of non periodic pulse train on the nonlinear behavior of radar power amplifier using mixer based NVNA
Taking advantage of a recently developed 20GHz six port mixer based nonlinear vector network analyzer (NVNA) prototype able to measure three frequencies simultaneously, the time domain tension and current waveforms are reconstructed at each chosen pulse of a non periodic pulse train starting from first pulse. This new instrument is used to study the influence of realistic radar pulse train on a 5W S-band GaN on silicon HEMT transistor.
