Phase-locked loop, radio frequency wireless receiver, transmitter and chip

The invention discloses a phase-locked loop, a radio frequency wireless receiver, a transmitter and a chip, the phase-locked loop comprises a phase frequency detector, a charge pump, a loop filter and a voltage-controlled oscillator which are connected in sequence, and the phase-locked loop further comprises an auxiliary phase-locked loop, a first signal processing unit and a second signal processing unit. The invention discloses a phase-locked loop, a radio frequency wireless receiver, a transmitter and a chip. A first signal processing unit mixes a generated second clock signal with an output signal of a voltage-controlled oscillator to generate a third clock signal; a second signal processing unit performs fractional frequency division processing on a first clock signal or an output signal of a voltage-controlled oscillator to generate a fourth clock signal, a fractional frequency division ratio far away from 0 or 1 is configured by changing the frequency division ratio of the first signal processing unit,
