A compact millimeter-wave slide screw impedance tuner allows reducing to a minimum the insertion loss between the tuner and the wafer-probe. The structure of the tuner uses a 1 mm slabline and adapters, an eccentrically rotating remotely controlled wideband tuning probe and a sliding rack on which the tuning-probe is attached; the position of the rack is controlled by a permanently anchored motorized pinion. The construction method allows for maximum compactness, needed in order to be able to attach the tuner directly on the wafer-probe and minimize the insertion loss, while maintaining key advantages of electro-mechanical tuners, such as robustness, linearity, simplicity, tuning resolution and calibration and compatibility with existing load pull software and technology.
