METHOD FOR SUPPORTING MULTIPLE BAND COEXISTENCE IN RADIO FREQUENCY MODULE AND DEVICE THEREOF

摘要

A method for supporting multiple band coexistence in a radio frequency module and the radio frequency module. The method involves receiving radio frequency signals of at least two frequency bands (S1300); mixing the radio frequency signals of different frequency bands by a local oscillator to different frequency ranges of a middle frequency to obtain middle frequency signals within the different frequency ranges corresponding to the different frequency bands (S1302); merging the middle frequency signals within the different frequency ranges corresponding to the different frequency bands in the frequency domains (S1304); sending the merged middle frequency signal to a double-channel or multi-channel analog/digital converter to perform an analog/digital conversion process of the middle frequency (S1306). The method can simply use one radio frequency module to achieve a simultaneous processing of the signals of more than two frequency bands.
