Abstract
A power amplifying system includes a voltage control oscillator (VCO), a frequency divider, a mixer and an adding amplifier. The VCO is configured to provide an input signal having a frequency that is a non-integer multiple of a predetermined frequency. The frequency divider is coupled to the VCO, and configured to receive the input signal and perform frequency division upon the input signal to respectively generate an in-phase signal and a quadrature signal corresponding to the input signal. The mixer is coupled to the VCO and the frequency divider, and configured to mix the input signal transmitted from the VCO and the in-phase signal transmitted from the frequency divider to output a mixed signal. The adding amplifier is coupled to the mixer and the frequency divider, and configured to integrate the mixed signal and the quadrature signal to generate an output signal having the predetermined frequency.
