More Information
Summary:A radio frequency (RF) control circuit is disclosed. The RF control circuit includes a transceiver module and a front-end module. The front-end module is connected to the transceiver module via a primary component carrier (PCC) path and a secondary component carrier (SCC) path. The front-end module is configured to receive an external data signal and transmit a local data signal. The transceiver module is configured to receive a PCC signal from the external data signal and transmitting the PCC signal from the local data signal through the PCC path and receiving a SCC signal from the external data signal and transmitting the SCC signal from the local data signal through the SCC path. The SCC path is controlled to be grounded such that interference of the local data signal for the PCC path on the external data signal for the SCC path is eliminated. A mobile terminal is also disclosed.
