James Julius Nahra 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).

  • System and method for detecting radio frequency signals over a range of powers
    Patent number: 8073411
    Abstract: The present invention is directed to a power detection circuit for use in a wireless transmitting device. The circuit makes use of multiple gain paths so that two or more scaling factors are provided. Each scaling factor allows the detector circuit to provide more ADC levels per dB and thus provide accurate power control over a wider power range than through the use of a single gain path and a single scaling factor.
    Type: Grant
    Filed: June 18, 2008
    Date of Patent: December 6, 2011
    Assignee: Cisco Technology, Inc.
    Inventors: John M. Blosco, James Julius Nahra
