Abstract
An apparatus and a method for balanced power amplification are provided. An amplifier includes a splitter configured to split an input signal into a first input signal and a second input signal that include a 90° phase difference. The amplifier further includes a first power amplifier (PA) configured to amplify the first input signal to generate a first output signal. The amplifier further includes a second PA configured to amplify the second input signal to generate a second output signal. The amplifier further includes a combiner configured to combine the first output signal and the second output signal that include the 90° phase difference to generate an output signal.
