Patent
Maury Microwave Inc. | Date: 2017-04-05

An impedance tuner includes a controller, an RF transmission line, and a movable capacitive object configured for movement commanded by the controller relative to the transmission line to alter impedance. A position sensor is configured to provide feedback position data to the controller indicative of the actual position of the capacitive object after it is moved. The controller is configured to utilize the feedback position data in a closed loop to position the capacitive object at a desired position within a tolerance.

An impedance tuner having an RF transmission line, with a single lead screw extending along the RF transmission line. A plurality of movable carriages are engaged with the lead screw, wherein each of the plurality of movable carriages is configured for independent movement relative to other carriages. A motorized drive system drives the plurality of movable carriages independently along the lead screw.

A solid state impedance tuner or impedance tuner system including a housing structure and at least two solid state tuner modules electrically combined and disposed in one package within the housing structure. Each tuner module includes at least one solid state control element. Another embodiment is directed to an impedance tuner module card configured in a standardized system architecture. The card includes a chassis board, and at least one solid state tuner module integrated on the card and supported on or by the chassis board, each module including at least one solid state control element. Methods for calibrating a solid state impedance tuner that includes at least two solid state tuner modules combined in one package are disclosed.

A mechanical impedance tuner has at least two probe carriages mounted for movement along an axis parallel to the center conductor. The at least two probe carriages including a first probe carriage and a second probe carriage. Each probe carriage has at least N probes where N is an integer equal to or greater than one, and at least one of the N probes is mechanically different or of different nominal geometry from the probes on at least one of the other carriages so that each such probe has an non-identical frequency response.

Patent
Maury Microwave Inc. | Date: 2013-05-28

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.

Systems and methods of measuring and determining noise parameters. An exemplary method measures noise data and determines element values of a device noise model for a device under test (DUT), using a test system including an impedance tuner coupled to an input of the DUT for presenting a controllable variable impedance to the DUT and a noise receiver coupled to an output of the DUT. Noise data is measured as a function of at least one measurement parameter. The measured data includes raw noise data read from the noise receiver, and is used to determine element values of the device noise model. The system may include a database of device models


Patent
