Hybrid Doherty Amplifier System and Method |
摘要 |
One embodiment of the invention includes an amplifier system. The system comprises a digital predistortion (DPD) system configured to receive an input signal and to provide the input signal as a first digital signal component along a first amplifier path and a second digital signal component along a second amplifier path. The system also comprises a first digital-to-analog converter (DAC) configured to convert the first digital signal component to a first analog signal component and a second DAC configured to convert the second digital signal component to a second analog signal component. The system further comprises a Doherty amplifier comprising a main amplifier in the first amplifier path that is configured to amplify the first analog signal component and a peak amplifier in the second amplifier path that is configured to amplify the second analog signal component.
