Abstract
A wideband frequency synthesizer and a frequency synthesizing method thereof are provided. The wideband frequency synthesizer includes a phase-locked loop unit, a first voltage-controlled oscillating unit and a first frequency mixer unit. The phase-locked loop unit receives a reference signal and a feedback signal and generates a first oscillating signal according to the reference signal and the feedback signal. The first voltage-controlled oscillating unit generates a second oscillating signal. The first frequency mixer is coupled to the phase-locked loop unit and the first voltage-controlled oscillating unit, receives the first oscillating signal and the second oscillating signal for mixing frequencies of the first oscillating signal and the second oscillating signal to generate an output signal and taking the output signal as the feedback signal for outputting to the phase-locked loop unit.
