Abstract
(EN)
The invention discloses a realization method for connection of a main transmitting and receiving access and a diversity antenna. The method comprises a radio frequency transceiver, a diversity antenna interface and a main antenna interface. The main antenna interface is connected with a radio frequency front end module. The diversity antenna interface is connected with a radio frequency switch. A diversity receiving port, a main receiving port and a main transmitting port are mounted in the radio frequency transceiver. The main transmitting port is connected with a duplexer through a radio frequency amplifier module. A filter and an integrated amplifier are contained in the duplexer. The duplexer is connected with the radio frequency switch which is used for carrying out bidirectional data transmission. The diversity receiving port is connected with the radio frequency amplifier module through a coupler. A current and the temperature can be reduced in a special LTE band without increasing an extra device; the OTA is improved; the user experience problem in a hand mode is optimized; and the method has wide application prospect, is novel in design and is a good innovation scheme.
