    摘要: A method and apparatus for power detection in a multi-mode communication device configured for operation in different modes or frequency bands. A detector monitors the power level of an amplified outgoing signal. The detector may be configured with a switch and two or more samplers. Responsive to the mode of operation, the detector adopts an optimal configuration to generate a power level feedback signal, which is provided to a digital signal processor or controller. Comparison of the power level feedback signal to a target value may occur to generate an amplifier control signal. The amplifier control signal controls the gain, applied by an amplifier, to the outgoing signal. During operation, the system monitors for a change in the mode of operation and upon responsive to a change, generates a switch control signal to reconfigure the detector configuration to match the new mode of operation.
