Title:
MIXER MODULE
Document Type and Number:
WIPO Patent Application WO/2017/107460
Kind Code:
A1
Abstract:
A mixer module (40), comprising: a switching mixer (400), which is controlled by a switch signal and used for receiving a input signal and generating an output signal; a modulating unit (402), which is coupled to the switching mixer (400) and used for generating the switch signal, the switching frequency of the switch signal being higher than, and having specific magnification relationship with, the input frequency of the input signal. The mixer module (40) controls the switching mixer (400) by means of the switch signal having a switching frequency much higher than the input frequency of the input signal, and oversamples the input signal, so as to make the energy of the output signal spectrum to be more concentrated, being able to avoid additional noises introduced by sidelobes or harmonics.
