The invention provides a base station radio-frequency signal receiving and transmitting circuit, a radio-frequency transmitting circuit and a signal transmitting method. The radio-frequency input connector is connected to the output radio-frequency connector by at least two stage of power amplifiers; wherein the operating frequency of each stage of power amplifiers includes at least two transmitting radio-frequency signal bands. When the multi-band radio frequency communication is required, the amplification of a plurality of transmitting radio-frequency signals can be realized only need that the operating frequency of each stage of power amplifiers includes a plurality of transmitting radio-frequency signal bands, so that the multi-band radio frequency communication can be realized. When realizing the multi-band radio-frequency communication, the invention does not need to set a plurality of radio-frequency modules, but integrates the functions of a plurality of radio-frequency modules into a radio-frequency
