Patent ID: 8301091

Claim:
A device for interfacing with a plurality of different types of network access points, the device comprising: a plurality of power amplifiers configured to provide a corresponding plurality of 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; a switch configured to select one of the plurality of signals to provide an output signal at a signal output node; a power detecting circuit configured detect power of the output signal, the power detecting circuit comprising a plurality of states corresponding to the plurality of different types of network access points, wherein the power detecting circuit outputs a voltage level at a detector output within the same voltage range for the plurality of signals in response to the plurality of states corresponding to the different types of network access points with which the plurality of signals are associated; and a coupler located between the switch and the signal output node and configured to couple the selected one of the plurality of signals to the power detector, wherein the power detecting circuit comprises: a power detector configured to output the voltage level; and a leveler connected between the coupler and the power detector, the leveler comprising the plurality of states corresponding to the plurality of different types of network access points, wherein the leveler is configured to select one of the plurality of states in response to a control signal, and wherein the leveler comprises an amplifier, the plurality of states corresponding to a plurality of selectable gains of the amplifier.
