Rf control circuit and mobile terminal

A mobile terminal, comprising a processor and a radio frequency (RF) control circuit connected to the processor, wherein the RF control circuit comprises:

• a transceiver module, configured to transmit a primary component carrier (PCC) signal of a local data signal and receive a PCC signal of an external data signal through a PCC path, and configured to transmit a secondary component carrier (SCC) signal of the local data signal and receive a SCC signal of the external data signal through a SCC path;
• a front-end module, configured to receive the external data signal and transmit the local data signal;
• and
• a working mode switching switch connected between the transceiver module and the front-end module, wherein when a harmonic signal generated by the local data signal on the PCC path is leaked to the SCC path, the working mode switching switch is turned on to make the harmonic signal output to the ground such that harmonic interference between the PCC path and the SCC path is eliminated;
• and
• wherein a switch-control terminal of the working mode switching switch is connected to the transceiver module, a switch-input terminal of the working mode switching switch is connected to a transmission sub-path of the SCC path, and a switch-output terminal of the working mode switching switch is grounded.
