Abstract

The embodiment of the invention discloses a carrier aggregation radio frequency circuit and a mobile terminal. The carrier aggregation radio frequency circuit comprise a radio frequency transceiver, a power amplifier, a radio frequency front-end facility and at least two duplexers, wherein the first sending of the radio frequency transceiver is connected with the first receiving end of the power amplifier, the first sending end of the power amplifier is connected with the first receiving end of the first duplexer, the first sending end of the first duplexer is connected with the first receiving end of the radio frequency front-end facility, the first sending end of the radio frequency front-end facility is connected with the second receiving end of the first duplexer, the second sending end of the first duplexer is connected with the first receiving end of the radio frequency transceiver, and the first duplexer is any one of at least two duplexers. Through the carrier aggregation radio frequency circuit disclosed by the embodiment of the invention, the use number of the power amplifier can be saved when performing carrier aggregation, and the material cost is saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a carrier aggregation radio frequency circuit and a mobile terminal. Background technique [0002] A carrier aggregation (Carrier Aggregation, CA) technology is a technology for increasing transmission bandwidth. The CA technology can aggregate 2 to 5 Long Term Evolution (LTE) Component Carriers (CCs), and can achieve a maximum transmission bandwidth of 100MHz, effectively improving the user equipment (User Equipment, UE) download rate. rate. [0003] At present, in order to realize carrier aggregation and prevent interference among multiple carriers, generally multiple carriers are respectively amplified by different power amplifiers (power amplifiers, PAs) and then transmitted. However, it is found in practice that using different power amplifiers for multiple carriers will still cause interference. Contents of the invention [0004] Embodiments of the prese...
