The present invention relates to the field of communications technologies, and in particular, to a radio frequency circuit switch chip, a radio frequency circuit, an antenna device, and an electronic apparatus.

Background

With the development of communication technology, more and more communication frequency bands can be supported by the mobile terminal. For example, an LTE (Long term evolution) communication signal may include a signal having a frequency between 700MHz and 2700 MHz.

Radio frequency signals that can be supported by a mobile terminal can be divided into low frequency signals, intermediate frequency signals, and high frequency signals. The low-frequency signal, the intermediate-frequency signal and the high-frequency signal respectively comprise a plurality of sub-frequency band signals. Each sub-band signal needs to be transmitted to the outside world via an antenna.

Thus, a Carrier Aggregation (CA) technique has been produced. Through carrier aggregation, a plurality of sub-frequency band signals can be aggregated together to improve the uplink and downlink transmission rate of the network.

Currently, the frequency resources of the various communication markets around the world are different from each other. Communication operators in different regions have different communication spectrum allocations, so that different frequency band combination requirements of carrier aggregation exist. However, the frequency band for aggregation in the current carrier aggregation is single, and the diversity is lacking, so that the above requirements cannot be met.
