Publication number: 20220036370Abstract: Methods and systems are disclosed that include the identification of one or more actions in an action flow that is intended to resolve a problem, and to guide a user through the one or more actions of such an action flow, dynamically adjusting the action flow during such guidance and/or subsequent thereto, using machine learning techniques. In some embodiments, such a method can include. for example, receiving outcome information at a machine learning system (where the outcome information is associated with an action of an action flow and the action flow comprises a plurality of actions), generating update information (where the update information is generated by the machine learning system based, at least in part, on the outcome information), and updating action information of the action (where the action information is updated based, at least in part, on the update information).Type: ApplicationFiled: July 31, 2020Publication date: February 3, 2022Inventors: Carlos Felipe Rodman, Mohammed Athaulla, Yogish KS, Rohan S.

Patent number: 11199568Abstract: A load pull system for making measurements on a DUT at millimeter wave frequencies using active tuning. The system uses phase and amplitude control of each signal at low frequency before being upconverted to the millimeter wave measurement frequencies. The measured signals at the DUT plane may be down-converted for measurement with a low frequency analyzer.Type: GrantFiled: September 24, 2019Date of Patent: December 14, 2021Assignee: Maury Microwave, Inc.Inventors: Giampiero Esposito, Mauro Marchetti, Sathya Padmanabhan, Gary R.

Patent number: 10652051Abstract: A load pull system and method for calibrating the system and conducting measurements on a Device Under Test (DUT). The system includes at least one passive tuner; and a modulated signal connected to the DUT input. The passive tuner is calibrated at multiple frequencies within the modulation bandwidth of the modulated signal. The impedance and measured quantities such as power at the DUT reference plane are determined using tuner s-parameters at multiple frequencies within the modulation bandwidth.Type: GrantFiled: August 28, 2018Date of Patent: May 12, 2020Assignee: Maury Microwave, Inc.Inventors: Gary R. Simpson, Sathya Padmanabhan, Steven M. Dudkiewicz, M. Tekamül Büber, Giampiero Esposito

Patent number: 10651528Abstract: A directional coupler operable at microwave and RF frequencies. Embodiments of directional coupler includes a main transmission line supporting transverse electromagnetic (TEM) or quasi-TEM wave mode propagation. A coupled transmission line supports TEM or quasi-TEM wave mode propagation. The coupled transmission line is adjacent to and oriented at an angle with respect to the main transmission line. A coupling hole is formed through conductive shielding between the main and coupled lines, the coupling hole formed at an intersection region between the main and coupled lines. The angle is nominally 60 degrees for optimal directivity and isolation.Type: GrantFiled: November 27, 2017Date of Patent: May 12, 2020Assignee: Maury Microwave, Inc.Inventors: M.

Patent number: 10560067Abstract: A multi-section probe and a tapered probe for impedance tuners to broaden the band width of the probes and hence the band width of the tuners. Each section of the multi-section probe has a nominal length equal to one quarter wavelength at a midpoint of the operating band. The tapered probe has a length equivalent to a plurality of one quarter wavelengths of the frequency midpoint. The multi-section probe and the tapered probe are configured to transform the characteristic impedance of the tuner transmission line step-by-step or continuously to a target impedance value.Type: GrantFiled: January 17, 2018Date of Patent: February 11, 2020Assignee: Maury Microwave, Inc.Inventors: M.

Patent number: 9614267Abstract: Embodiments of a broadband capacitor in a coaxial line are described. A capacitor may be realized in the center conductor of the coaxial line, and this aspect has two different embodiments. One embodiment forms the capacitor between the flat faces of an interrupted inner conductor structure. A second embodiment forms the capacitor between overlapping fingers of the female inner conductor and the male inner conductor, where the fingers can be realized in different ways. In another embodiment, a capacitor is realized in the outer conductor of the coaxial line, between fingers of a female portion of the outer conductor and a male portion of the outer conductor, where the fingers can be realized in different ways.Type: GrantFiled: May 16, 2016Date of Patent: April 4, 2017Assignee: Maury Microwave, Inc.Inventors: M.
