Abstract

The invention discloses a radio-frequency front-end transceiver which comprises an antenna module, radio-frequency modules in various modes and a multiplexer module, wherein the multiplexer module is used for separating signals received by the antenna module to obtain frequency-band signals in various modes and transmitting the frequency-band signals in various modes to the corresponding radio-frequency modules in various modes; or the multiplexer module is used for receiving the frequency-band signals sent by the radio-frequency modules in various modes and transmitting the frequency-band signals to the antenna module. The invention also discloses a multi-mode mobile terminal. By adopting the radio-frequency front-end transceiver and the multi-mode mobile terminal, only one antenna is used, thus occupying less space, avoiding mutual interference of signals between two or more antennas, and having good radio-frequency performance.

Description

technical field [0001] The invention relates to the communication field, in particular to a radio frequency front-end transceiver and a multi-mode mobile terminal. Background technique [0002] With the continuous development of mobile communication technology and market demand, mobile terminals of various standards have emerged, such as GSM / GPRS / EDGE, PHS, CDMA95 / 2000 1X, CDMA1X-EVDO, WCDMA / HSDPA / HSUPA, TD-SCDMA, Mobile terminals of WiMax and other standards. [0003] When a mobile terminal meets the communication requirements of different standards, it is called a multi-mode mobile terminal. The multi-mode mobile terminal is a product that has emerged in response to the needs and development of the market. Today, it has become an indispensable part of the entire mobile terminal consumer market. The publication number published on October 1, 2008 is CN101277488A, and the name is an application document for an invention patent of a WiMax dual-mode mobile terminal and its s...
