Publication number: 20230344386Abstract: A microwave power generator comprises a driver stage having a driver transistor and an output stage coupled to the driver stage and having a power amplifier. A driver limiter is coupled to a DC voltage supply and includes a resistor coupled between the DC voltage supply and the driver transistor. The resistor has a resistance value effective to reduce a DC voltage supplied by the DC voltage supply to a control voltage that is applied to the driver transistor to set an output power of the driver transistor at a level effective to drive the power amplifier of the output stage to its maximum output power without exceeding a maximum input power rating of the power amplifier.Type: ApplicationFiled: February 24, 2023Publication date: October 26, 2023Inventor: Christopher Michael Owen

Publication number: 20190350648Abstract: An imaging component comprises shaft and a cavity extending across the shaft from its proximal end towards its distal end. The cavity removably receives at least one of a plurality of different instruments. A wall of the cavity comprises an elongated opening in communication with an exterior of the shaft at least partially along the shaft. An imaging transducer is coupled to the distal end of the shaft. The imaging component is advanced to a target site either alone or with a first instrument coupled thereto. A therapeutic or diagnostic procedure is performed with the first instrument. The first instrument is then retracted and removed from the imaging component while the imaging component stays at the target site. A second instrument is then coupled to the imaging component and advanced to the target site to perform a further therapeutic or diagnostic procedure.Type: ApplicationFiled: May 16, 2019Publication date: November 21, 2019Inventors: Christopher Michael OWENS, Edmond Ming Wai CHIU, Jiayu CHEN, Thomas Burnell REEVE, III

Patent number: 9477851Abstract: A combiner includes N coaxial cables each configured to connect to a respective output of N radio frequency power amplifiers, where N is an integer greater than one. Each of the N coaxial cables is configured to receive an amplified radio frequency signal from a respective one of the N radio frequency power amplifiers. A board includes capacitances and is configured to connect to each of the N coaxial cables and combine the radio frequency signals. The N coaxial cables and the capacitances provide N inductance and capacitance combinations. A connector is configured to connect an output of the board to a load.Type: GrantFiled: July 28, 2014Date of Patent: October 25, 2016Assignee: MKS Instruments, Inc.Inventor: Christopher Michael Owen
