  • Method and apparatus for determining a response of a DUT to a desired large signal, and for determining input tones required to produce a desired output
    Patent number: 7924026
    Abstract: A method for determining input tones required to produce a desired output includes the step of extracting a linearization of a spectral map representing a device under test (DUT) that i) is under drive of a large signal having one or more fundamental frequencies with associated amplitudes and phases, and ii) produces an approximation of a desired output having at least one unwanted spectral component. The method includes the further step of using an inverse of the extracted linearization to determine the input tones required to produce the desired output under a given load condition.
    Type: Grant
    Filed: March 24, 2008
    Date of Patent: April 12, 2011
    Assignee: Agilent Technologies, Inc.
    Inventors: Jason M. Horn, David E. Root, Daniel Gunyan, Jianjun Xu
  • Broadband balanced frequency converter
    Patent number: 7848728
    Abstract: A broadband balanced frequency converter (“BBFC”) in signal communication with a frequency source is disclosed. The BBFC may include a mixer and an active balancing element in signal communication with the mixer.
