    Abstract: The accuracy of an impedance tuner may be improved and the size may be reduced by using linear actuators instead of rotary motors. The linear actuator may be integrated with position sensors to allow very small size, and implemented with a servo system for best accuracy and speed. Spring loaded arms holding the mismatch probes allow the tuner to operate in any orientation to further fit into small spaces. The small size reduces losses by allowing direct connection to wafer probes for on-wafer measurement systems.

    Abstract: An impedance tuner system that uses at least one passive tuner and at least one active tuner to control one or more impedances at a reference plane or planes. Each of the at least one active tuners operates at a target frequency at which the impedance is to be controlled. The passive tuner is set to a passive tuner target impedance before active tuners are set to their target impedances.

    Abstract: A measurement system and method for conducting measurements on a device-under-test (DUT). The system includes, in one embodiment, a passive impedance controlling tuner, and a signal transmission line, the tuner including a signal transmission line segment as at least part of the signal transmission line. A signal coupling device is coupled in a non-contacting relationship to the signal transmission line between a signal port of the DUT and the tuner for sampling signals propagating between the passive impedance controlling tuner and the DUT to allow measurement of an actual impedance presented to the DUT with the DUT in place in the measurement system during measurement of DUT characteristics. Measurement system equipment receives response signals from the signal coupler. The measurement system is configured to conduct measurement of DUT characteristics without pre-characterizing the impedance controlling tuner.

    Abstract: A solid state impedance tuner or impedance tuner system includes a control element array with a plurality of solid state control elements configured to be turned on simultaneously to achieve a desired impedance state. The control element array comprises N solid state control elements arranged along an RF transmission line. A controller selectively turns on or off each control element by application of a control signal to vary an impedance presented by the control element array, Another aspect is an impedance tuner module card configured in a standardized system architecture, with a chassis board, and at least one solid state tuner module integrated on the card A chassis electrical connector connected to the tuner module is configured for connection to a corresponding backplane connector. Methods for calibrating a solid state impedance tuner that includes at least two solid state tuner modules combined in one package are disclosed.

    Abstract: A tuner system for conducting measurements on a Device Under Test (DUT) includes at least one passive tuner, and calibration data for the at least one passive tuner including a set of s-parameters at a set of calibration frequencies. A measurement on the DUT is done at a measurement frequency at which the at least one passive tuner is not calibrated. The tuner s-parameters at the measurement frequency are determined by interpolation between or extrapolation from the s-parameters at calibration frequencies.
