Title:
SIGNAL GENERATION APPARATUS AND METHOD FOR GENERATING LOW-PHASE NOISE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2024/082586
Kind Code:
A1
Abstract:
Disclosed in the present application are a signal generation apparatus and method for generating a low-phase noise signal. The signal generation apparatus comprises a signal preprocessing circuit, a frequency mixing phase-locked loop circuit and a signal post-processing circuit, wherein the signal preprocessing circuit is used for performing frequency division or frequency multiplication processing on a signal to be optimized, so as to acquire a preprocessed signal, the frequency mixing phase-locked loop circuit is used for performing loop locking on the preprocessed signal, so as to acquire a loop phase-locked signal, and the signal post-processing circuit is used for performing amplification, frequency division or frequency multiplication processing on the loop phase-locked signal, and outputting an acquired denoised signal as an optimized signal. In the frequency mixing phase-locked loop circuit, a frequency mixing loop is built using a frequency mixer, so as to compensate for the limitation of a decimal loop on a fractional frequency division method, and optimize the stray of a signal. The signal generation apparatus is not limited by the frequency of an input/output signal, can achieve an ultra-wideband input/output from a low frequency to a millimeter-wave frequency band, and can be suitable for multiple radio frequency systems.
