Patents by Inventor Thomas Michael Craig

Thomas Michael Craig has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Power sensor module for microwave test systems
    Patent number: 6397160
    Abstract: A module for use in automatic test equipment is disclosed. The module is especially useful for performing power measurements on high frequency devices. The module includes a power sensor and a plurality of EEPROM's that store reflection coefficient data for the power sensor. Computerized control circuitry in the automatic test equipment uses the stored data to reduce impedance mismatch uncertainties in the power measurements.
    Type: Grant
    Filed: June 4, 1999
    Date of Patent: May 28, 2002
    Assignee: Teradyne, Inc.
    Inventors: Thomas Michael Craig, Matthew Thomas Begg
  • Noise source module for microwave test systems
    Patent number: 6268735
    Abstract: A module for use in automatic test equipment is disclosed. The module is especially useful for measuring noise parameters of high frequency devices. The module includes a noise generator and a plurality of EEPROM's that store reflection coefficients and ENR data for the noise generator. Computerized control circuitry in the automatic test equipment uses the stored data to reduce impedance mismatch and Excess Noise Ratio (ENR) data uncertainties in the measured noise parameters.
