A radio frequency circuit and a communication terminal. A diversity antenna (20) is provided in a diversity region and is connected to a radio frequency transceiver circuit (10) by means of an intermediate-high frequency bidirectional link (30). The intermediate-high frequency bidirectional link (30) is used to transmit, to the diversity antenna (20), a high frequency signal and/or an intermediate frequency signal emitted by the radio frequency transceiver circuit (10), and to transmit, to the radio frequency transceiver circuit (10), a high frequency signal and/or an intermediate frequency signal received by the diversity antenna (20) in a diversity reception manner. A main antenna (40) is provided in a main region and is connected to the radio frequency transceiver circuit (10) by means of an intermediate-high frequency receiving link (50). The intermediate-high frequency receiving link (50) is used to transmit, to the radio frequency transceiver circuit (10), a high frequency signal and/or an intermediate
