A wideband hybrid harmonic high-speed impedance load pull tuner uses the active loop feedback technique combined with transmission type electronic tuner in the active feedback loop and electro-mechanical slide screw harmonic pre-matching tuning. The tuner allows millisecond two or three harmonic tuning with maximum Gamma close to 1 using reduced feedback injection power compared to purely active systems. The system is pre-calibrated and allows fast precision tuning even under nonlinear feedback amplifier power conditions when operated with in-situ wave measurement. Using wideband power dividers, instead of band-limited circulators, to convert the reflection electronic tuner into a transmission amplitude and phase modulator, allows multi-harmonic hybrid operation.
