Title:
PHASE ADJUSTMENT DEVICE AND SYSTEM FOR EXTRACTING TERAHERTZ SIGNALS
Document Type and Number:
WIPO Patent Application WO/2020/024570
Kind Code:
A1
Abstract:
The present application relates to a phase adjustment device and a system for extracting a terahertz signal. A phase adjustment device, which is characterized in comprising: a phase-locked loop module used for receiving a reference signal so as to output an oscillator signal and a demodulator signal; a frequency dividing module used for receiving the oscillator signal so as to output a phase shift signal and a frequency division signal; and a frequency tracking module used for receiving the demodulator signal so as to output a capture range signal, wherein the phase-locked loop module is further used for receiving the frequency division signal and the capture range signal. The foregoing phase adjustment device may control the operation of the phase-locked loop module by means of the frequency tracking module outputting the capture range signal so that the phase-locked loop module may automatically capture and lock a wide range of terahertz signals, thereby outputting a phase shift signal having high precision and stability.
