Original Abstract Submitted

a radio-frequency circuit is used in simultaneous transfer of a radio-frequency signal of 4g and a radio-frequency signal of 5g, and includes a first transfer circuit that selectively receives the 4g radio-frequency signal or the 5g radio-frequency signal, and transfers a radio-frequency signal of a first communication band including a first transmission band and a first reception band and a radio-frequency signal of a second communication band including a second transmission band and a second reception band. the first and second transmission bands at least partially overlap. the first transfer circuit includes a first power amplifier that amplifies transmission signals of the first and second communication bands, and a first transmission filter that has a first passband including the first and second transmission bands, and passes the transmission signals of the first and second communication bands output from the first power amplifier.
