RADIO FREQUENCY FRONT-END MODULE USED FOR 5G NON-STANDALONE AND SUPPORTING LTE/NR DUAL CONNECTION

摘要

Disclosed is a radio frequency front-end module used for 5G non-standalone and supporting LTE/NR dual connection. The module comprises a baseband chip (1) used for generating a 4G full-band signal and a 5G band signal, and a switch group (2), wherein output ends of the baseband chip (1) are respectively loaded to a lower-level circuit by means of the switch group (2). The front-end module provided in the present invention is combined with the baseband chip, which generates the 4G full-band signal and the 5G band signal, and the switch group, so that the EN-DC of a 4G band and a 5G refarming band is realized, and the necessity of externally providing a 5G power amplifier is avoided; moreover, the output of different bands can be realized by means of the turning-on/turning-off of the switch group.
