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

摘要

A method and a device for supporting multiple bands coexistence in a radio frequency module are provided in the embodiments of the present invention. The method includes: receiving radio frequency signals of at least two frequency bands; down frequency mixing the radio frequency signals of different frequency bands through a local oscillator to different intermediate frequency ranges to obtain intermediate frequency signals within the different frequency ranges corresponding to the different frequency bands; merging the intermediate frequency signals within the different intermediate frequency ranges corresponding to the different frequency bands in frequency domain; and performing intermediate frequency conversion from analog to digital for the merged intermediate frequency signals through a multi-channel analog-digital converter. The method and device in the embodiments of the present invention can implement concurrent processing of signals in at least two frequency bands by using one radio frequency module in a simple way.
