  • Power detector for multi-band network access
    Patent number: 8301091
    Abstract: A device for interfacing with multiple different types of network access points includes multiple power amplifiers, a switch and a power detecting circuit. The power amplifiers are configured to provide corresponding signals associated with the different types of network access points, each signal having at least one parameter different than a corresponding parameter in another signal. The switch is configured to select one of the signals to provide an output signal. The power detecting circuit is configured to detect power of the output signal, and includes multiple states corresponding to the multiple different types of network access points. The power detecting circuit outputs a voltage level within the same voltage range for the signals in response to the multiple states corresponding to the different types of network access points with which the signals are associated.
