  • System and method for measuring essential power amplification functions
    Patent number: 6993438
    Abstract: An apparatus includes a device under test, a network analyzer, an internal amplifier, a first switch, a second switch, a third switch, a first air-line directional coupler, and a first attenuator. A method of characterization measurement includes providing a harmonics signal from the device under test to a spectrum analyzer, providing a generated signal and a reflected signal to a first receiver disposed within a network analyzer, and recording a parameter deviation of the network analyzer.
    Type: Grant
    Filed: March 24, 2005
    Date of Patent: January 31, 2006
    Assignee: Agilent Technologies, Inc .
