The embodiment of the invention provides a radio frequency circuit switch chip, a radio frequency circuit, an antenna apparatus and an electronic device. The radio frequency circuit switch chip comprises a first switch, a second switch and a combiner, wherein an input end of the first switch comprises an intermediate frequency port and a high frequency port, the intermediate frequency port is used for receiving and sending intermediate and low frequency signals, the high frequency port is used for receiving high radio frequency signals, the first switch comprises at least two output ends, the input end of the second switch comprises a low frequency port, the low frequency port is used for receiving and sending low radio frequency signals, and the first switch and the second switch selectively turn on the combiner so as to realize the carrier aggregation of the low frequency signals and the intermediate frequency signals or the carrier aggregation of the low frequency signals and the high frequency signals. The radio frequency circuit switch chip can control the carrier aggregation of radio frequency signals of different frequency bands, and thus the diversity of carrier aggregation of the radio frequency signals by the electronic device can be improved.
