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, a first combiner and a second combiner, when a first output port and a second output port of the first switch are separately connected with the first combiner, the carrier aggregation of an intermediate frequency signal and a high frequency signal is realized, when a third output port of the first switch and the second switch are separately connected with the combiner, the carrier aggregation of the intermediate frequency signal, the high frequency signal and a low frequency signal is realized; and when the first switch is disconnected with the first combiner, and when the third output port of the first switch and the second switch are separately connected with the combiner, the carrier aggregation of the high frequency signal or the intermediate frequency signal and the low frequency signal is realized. The radio frequency circuit switch chip controls the radio frequency signals of different frequency bands to realize the carrier aggregation so as to improve the carrier aggregation diversity of the radio frequency signals executed by the electronic device.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency circuit switch chip, a radio frequency circuit, an antenna device and electronic equipment. Background technique [0002] With the development of communication technologies, mobile terminals can support more and more communication frequency bands. For example, an LTE (Long Term Evolution, long term evolution) communication signal may include a signal with a frequency between 700 MHz and 2700 MHz. [0003] The radio frequency signals that the mobile terminal can support can be classified into low frequency signals, intermediate frequency signals and high frequency signals. Wherein, each of the low-frequency signal, the intermediate-frequency signal and the high-frequency signal includes a plurality of sub-frequency band signals. Each sub-band signal needs to be transmitted to the outside world through an antenna. [0004] Thus, a carrier aggregation (Car...
