Abstract
A load-pull measurement system uses a PC control computer, interface, calibration method and at least one slide screw impedance tuner with two dual-tuning probes; the tuner probes share the same slabline; they are inserted diametrically at fixed depth (distance from the center conductor) from both sides into the channel and move only horizontally along the slabline. The tuner does not have cumbersome adjustable vertical axes controlling the penetration of the probes and its low profile is optimized for on-wafer operations. The carriages holding the probes are moved at high speed along the slabline using linear electric actuators. An efficient de-embedding calibration method serves speeding up additionally the measurement procedure.
