Abstract

The invention discloses a wireless communication transceiver system. The wireless communication transceiver system comprises a wireless transceiver unit, a receiving processing unit, a sending processing unit, a duplexer and a transceiver antenna, wherein both the receiving processing circuit and the sending processing circuit are connected with the duplexer; and the duplexer is connected with the transceiver antenna to receive and send the wireless signal; a sending access of the duplexer is a low-pass filter which can improve insertion loss, so that the power consumption is saved, simultaneously, the maximum power to be output by a power amplifier in the receiving processing circuit and the sending processing circuit is reduced, thus the terminal heat dissipation is reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication transceiver system using dual antennas. Background technique [0002] Existing 3G / 4G FDD (Frequency Division Duplex) terminals adopt a full-duplex design, so the transceiver channels will work simultaneously. In the traditional radio frequency architecture, the duplexer (Duplex) is an essential device. Its main function is: (1) merge the transceiver channels into one channel; (2) provide isolation between the transceiver channels, that is, attenuation The radio frequency signal of the transmission path is noisy in the receiving frequency band to prevent it from interfering with the receiving signal. [0003] The reason for providing isolation between the transmit and receive paths is that the receive path is required to work even at very weak levels (-110dBm is typical today). The transmission path is a high-power path, which can reach a strength o...
