WIPO Patent Application WO/2015/053435
Kind Code:
A1
Abstract:
A wideband high-linearity amplifier comprises: a plurality of predistortion units for respectively linearizing digital signals in a plurality of bands; a synthesis unit for synthesizing output signals from the predistortion units; a single amplification unit for amplifying signals outputted from the synthesis unit; a distribution unit for respectively separating the signals for the plurality of bands from the output signals of the amplification unit; a plurality of reverse compensation attenuation units for respectively attenuating the separated signals for the plurality of bands; and a feedback gyro for respectively providing feedback regarding the attenuated signals for the plurality of bands to a predistortion unit in the corresponding band from among the plurality of predistortion units.
