Abstract
An integrated hybrid (active-passive) harmonic impedance tuner uses a fixed and an adjustable directional coupler (wave-probe) and a number of independent wideband tuning probes, all mounted inside the same slabline and housing. The tuning probes are inserted between the fixed and the mobile wave-probes. The fixed wave-probe samples a portion of the forward travelling signal at the fundamental frequency, injects it into a power amplifier and the mobile wave-probe adjusts the phase and amplitude of the amplified signal and injects it back into the slabline towards the DUT. The mobile carriages and tuning probes are automated. The mobile wave-probe is either fully or partially (horizontal only) automated or fully manually controlled. Feedback signal phase and amplitude control is obtained through the horizontal and vertical movement of the mobile wave-probe.
