Title:
RADIO FREQUENCY SYSTEM AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/065713
Kind Code:
A1
Abstract:
The radio frequency system and device. The radio frequency system comprises a transmitting front end, a TDD signal receiving front end, an FDD signal receiving front end, an interference signal receiving front end and a digital processing module. When the TDD signal receiving front end is used for receiving a first TDD signal, a first switch module is in an on state, and an antenna module is used for outputting the first TDD signal to the TDD signal receiving front end; a counterclockwise circulator is used for outputting an interference signal from the transmitting front end to the TDD signal receiving front end and to the interference signal receiving front end; the TDD signal receiving front end is used for outputting the first TDD signal and a first interference signal to the digital processing module, and the interference signal receiving front end is used for outputting a second interference signal to the digital processing module; and the digital processing module is used for performing cancellation processing on the first interference signal according to the second interference signal.
