The frequency divider is configured to perform frequency division processing on the fifth signal to obtain the feedback signal and output the feedback signal to the phase comparator.

[0069] In some embodiments of the embodiment, the loop filter in the phase-locked loop unit 43 includes a passive loop filter. The passive loop filter mainly includes passive elements such as resistors (R) and capacitors (C). Compared with an active loop filter, the passive loop filter is simpler and does not include an amplifier, thereby avoiding the noise that can be introduced by the amplifier, improving the signal accuracy and stability output by the phase-locked loop unit 43, and improving the quality of the final measurement and control signal. In the embodiment, when the phase-locked loop unit 43 uses a passive loop filter, the oscillator in the phase-locked loop unit 43 preferably uses a VCO with low tuning voltage.
