Abstract
The present application provides a multiband power amplification apparatus. The first input terminal receives a signal in a frequency band f1; the second input terminal receives a signal in a frequency band f2. The first adjustment module adjusts a first channel of signal and then outputs an adjusted first channel of signal to the first adder. The second adjustment module adjusts a third channel of signal and then outputs an adjusted third channel of signal to the first adder. The first adder converges the signal adjusted by the second adjustment module and the signal output by the first adjustment module and then outputs a converged signal to a first digital-to-analog converter. The second adder converges a second channel of signal and a fourth channel of signal and then outputs a converged signal to a second digital-to-analog converter.
