Abstract: A wideband highly linear amplifier includes a plurality of pre-distortion units for respectively linearizing digital signals of a plurality of bands, a synthesis unit for synthesizing output signals of the pre-distortion units, a single amplifier for amplifying signals outputted from the synthesis unit, distribution units for respectively separating the signals for each of the plurality of bands from the output signals of the amplifier, a plurality of inverse compensation attenuators for respectively attenuating the separated signals for each of the plurality of bands, and a feedback path for respectively feeding the attenuated signals for each of the plurality of bands back into the pre-distortion unit of the corresponding band out of the plurality of the pre-distortion units.

Abstract: A communication device for power saving and a method for controlling power thereof are provided. The communication device includes a power amplifying unit and a control unit. The power amplifying unit generates an output signal obtained by amplifying a downlink signal, using a supply voltage, and outputs the output signal. The control unit determines a current state by comparing predetermined downlink reference information with output signal information on the output signal, and, if the current state is an active state as a comparison result, controls the supply voltage to correspond to the output signal information. Accordingly, power for amplifying a signal can be controlled according to communication traffic, thereby preventing consumption of unnecessary power.
