1. A radio frequency front-end circuit, comprising:
a gating switch, separately connected to a first antenna, a second antenna, and a radio frequency circuit module; and
a double-pole double-throw switch, separately connected to the gating switch, a third antenna, a fourth antenna, and a first radio frequency circuit; wherein
the gating switch is a three-pole three-throw switch;
the radio frequency circuit module is connected to a first target antenna in the first antenna and the second antenna by using the gating switch, and receives and/or transmits a signal by using the first target antenna; or the radio frequency circuit module is connected to a second target antenna in the third antenna and the fourth antenna by using the gating switch and the double-pole double-throw switch, and receives and/or transmits a signal by using the second target antenna;
in a case that the radio frequency circuit module is connected to the first target antenna in the first antenna and the second antenna, the first radio frequency circuit is connected to the second target antenna in the third antenna and the fourth antenna by using the double-pole double-throw switch, and receives and/or transmits a signal by using the second target antenna; and
in a case that the radio frequency circuit module is connected to the second target antenna in the third antenna and the fourth antenna, the first radio frequency circuit is connected to a third target antenna in the third antenna and the fourth antenna, other than the second target antenna, by using the double-pole double-throw switch, and receives and/or transmits a signal by using the third target antenna.
