Abstract
A wireless communication device that includes a power amplifier and an antenna is provided. The power amplifier includes a first and a second power amplifying paths and a first and a second matching modules. The first and the second power amplifying paths receive a first and a second input signals respectively. The first matching module includes a first input variable load and a first phase-shifting circuit to respectively adjust the magnitude and the phase of the first input signal to generate a first output signal. The second matching module includes a second input variable load and a second phase-shifting circuit to respectively adjust the magnitude and the phase of the second input signal to generate a second output signal. The antenna is coupled to the power amplifier to transmit the first and the second output signals.
