Abstract :
An enhanced pulsed mode for RF measurements based on synchronized repetitive signals is proposed, with the unique capability to manage repetitive sets of pulses and consequently to investigate the pulse-to-pulse behavior of high power active devices. This new technology is applied to a sampler-based NVNA (nonlinear vector network analyzers), without any dynamical losses. Burst of pulses measurements of high power AlGaN/GaN transistors are performed in a multi-harmonic passive load-pull environment. Time domain waveforms and S21 pulse-to-pulse phase within the burst are acquired and discussed.
