Claim Text:
1. A device comprising: a package that includes a terminal for receiving a first input signal; an active transistor die coupled to the package and electrically coupled to the terminal, wherein the active transistor die is configured to receive a second input signal corresponding to the first input signal, and to amplify the second input signal to produce an output signal; a detector, coupled to the package and electrically coupled to the terminal, and configured to sense a signal characteristic of the first input signal, and to produce one or more detector signals indicating the signal characteristic; and control circuitry, coupled to the package and electrically coupled to the active transistor die and to the detector, wherein the control circuitry is configured to acquire the one or more detector signals indicating the signal characteristic from the detector, to estimate, based on the one or more detector signals, an out-of-band power level in one or more out-of-band frequency ranges, and when the out-of-band power level is estimated to exceed a pre-determined level, to reduce a power level of the first input signal to produce the second input signal.
