Title:
RADIO FREQUENCY APPARATUS AND COMMUNICATION TERMINAL
Document Type and Number:
WIPO Patent Application WO/2017/088425
Kind Code:
A1
Abstract:
Provided is a radio frequency apparatus, comprising a radio frequency front-end module, a power amplification module, a radio frequency transceiving module, a plurality of duplexers and a switching circuit. The radio frequency front-end module comprises a plurality of radio frequency switching ports, wherein each of the radio frequency switching ports is respectively connected to the power amplification module and the radio frequency transceiving module by means of a duplexer. The plurality of radio frequency switching ports comprise a multiplexing switching port connected to the switching circuit. The plurality of duplexers comprise a first duplexer and a second duplexer connected to the switching circuit. The switching circuit is used to connect the multiplexing switching port and the first duplexer to form a first switching path, or connect the multiplexing switching port and the second duplexer to form a second switching path. Also provided is a communication terminal. By providing the switching circuit, the radio frequency apparatus can realize design of communication terminals within different frequency band ranges on the same board.
