Radio frequency front-end architecture

The invention discloses a radio frequency front-end architecture. The radio frequency front-end architecture comprises a radio frequency transceiver, a signal processor, a path selection switch and a broadband filter, wherein the radio frequency transceiver is used for receiving and/or transmitting a signal; the signal processor is used for processing the signal; the path selection switch is used for selecting a first signal transmission path matched with the frequency range of the signal; and the broadband filter is used for transmitting signals of at least two frequency bands. According to the radio frequency front-end architecture, the broadband filter is shared by different signal paths, so the cost of the radio frequency front-end architecture is reduced while the radio frequency front-end architecture has better working performance. 本申请公开了一种射频前端架构，所述射频前端架构包括：射频收发机、信号处理器、通路选择开关和宽带滤波器；其中，所述射频收发机，用于接收和/或发射信号；所述信号处理器，用于对所述信号进行处理；所述通路选择开关，用于选择与所述信号的频率范围匹配的第一信号传输通路；所述宽带滤波器，用于传输至少两个频段的信号。本申请通过不同信号通路共用宽带滤波器，使得射
