1. A radio frequency circuit switch chip is characterized by comprising a first switch module, a second switch, a first combiner module and a second combiner, wherein the first switch module comprises a third switch component, a fourth switch component and a fifth switch component;

  • the output ends of the third switch assembly and the fourth switch assembly are respectively connected with the input end of the first combiner module;

    the output end of the first combiner module is connected with the input end of the fifth switch component;

    the output ends of the fifth switch component and the second switch are respectively connected with the input end of the second combiner;

    when the first switch module is connected with the first combiner module, the first combiner module carries out carrier aggregation on the high-frequency signal and the intermediate-frequency signal output by the first switch module to form a first aggregation signal, and when the first switch module and the second switch are respectively communicated with the second combiner, the second combiner carries out carrier aggregation on the first aggregation signal and the low-frequency signal output by the second switch;

    when the first switch module is disconnected with the first combiner module and the first switch module and the second switch is respectively connected with the second combiner, the second combiner carries out carrier aggregation on the high-frequency signal or the medium-frequency signal output by the first switch module and the low-frequency signal output by the second switch.
