Abstract

The embodiment of the invention discloses a mobile terminal radio frequency front-end comprising a first main antenna, a diversity antenna, a second main antenna, a quadruplexer, a first filter, a second filter, a third filter, a fourth filter, a fifth filter, a sixth filter, a seventh filter, an eighth filter, a first power amplifier, a second power amplifier, a third power amplifier, a fourth power amplifier, a fifth power amplifier, a sixth power amplifier, a quadruplexer, a duplexer, a first radio frequency switch, a second radio frequency switch, a first RF transceiver, a second RF transceiver and a controller. The embodiment of the invention also discloses a mobile terminal. With application of the mobile terminal radio frequency front-end and the mobile terminal, the number of the antennas in the internal part of the mobile terminal can be reduced, and internal interference and complexity of the antenna design can be reduced.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a radio frequency front end of a mobile terminal and the mobile terminal. Background technique [0002] In order to meet the requirements of single-user peak rate and system capacity improvement, the most direct method is to increase the system transmission bandwidth. The LTE-Advanced system proposes a carrier aggregation method to increase the transmission bandwidth. At present, most of the mobile terminals supporting carrier aggregation adopt Qualcomm's uplink 2CC and downlink 3CC carrier aggregation scheme, which needs to be realized by using 2 main antennas and 2 diversity antennas. [0003] Existing mobile terminals are becoming more and more light and thin, the internal space of mobile terminals is becoming smaller and smaller, and the electromagnetic environment is very complex. The existing 4-antenna carrier aggregation solution has too many antennas, which requires the layout of ...
