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

when the first switch turns on the fourth switch and the second switch and the third switch turn off, high-frequency signal non-carrier aggregation is realized;
when the second switch is switched on and the first switch and the third switch are switched off, the non-carrier aggregation of the intermediate frequency signals is realized;
when the third switch is switched on and the first switch and the second switch are switched off, low-frequency signal non-carrier aggregation is realized;

It should be noted that the above embodiment only exemplifies that the filtering unit 23 includes 2 filters and7 duplexers. In other embodiments, the filtering unit 23 may further include other numbers of filters and duplexers.
In a Long Term Evolution (LTE) communication network, according to different Duplex modes, a communication Frequency band of LTE is divided into two types, namely Frequency Division Duplex (FDD) and Time Division Duplex (TDD). In the communication frequency band in the FDD mode, the uplink and downlink communication links use different frequencies, and at this time, the rf circuit needs a duplexer to filter the uplink and downlink communication signals. In the communication frequency band in the TDD mode, the uplink and downlink communication links use the same frequency and transmit radio frequency signals in different time slots, and at this time, a filter is required in the radio frequency circuit to filter the uplink and downlink communication signals.
Therefore, in practical applications, the number of filters and the number of duplexers included in the filtering unit 23 depend on the duplex mode of the radio frequency signals of each frequency band transmitted by the radio frequency transceiver 21. In the frequency band of the FDD mode, a duplexer is connected with a radio frequency transmitting port and a radio frequency receiving port; in the frequency band of the TDD mode, a radio frequency transmitting port and a radio frequency receiving port are connected with a filter. For example, the band1 and the band2 frequency bands operate in an FDD mode, and the transmitting ports and the receiving ports of the band1 and the band2 radio frequency signals are connected with duplexers; and the band40 and the band41 frequency bands work in a TDD mode, and the transmitting ports and the receiving ports of the band40 and the band41 radio frequency signals are connected with filters.
Referring to fig. 6, in some embodiments, the radio frequency circuit switch chip 24 includes a first switch 241, a second switch 242, a third switch 243, and a combiner 244.

The combiner 244 may be a triple-band combiner. The output of the combiner 244 is connected to the antenna 25.
The above connection relation merely represents a direct or indirect connection relation between the components, and does not represent an electrically connected state between the components connected to each other.
In some embodiments, the sub-input ports c1, c2, c3 may be connected to high frequency ports in the radio frequency transceiver 21, the sub-input ports c4, c5, c6 may be connected to intermediate frequency ports in the radio frequency transceiver 21, and the sub-input ports c7, c8, c9 may be connected to low frequency ports in the radio frequency transceiver 21, respectively.

When the switch 241 is turned on any one of c1, c2 and c3, the switch 242 is turned off, and the switch 243 is turned on any one of c7, c8 and c9, the combiner 244 may implement carrier aggregation of the high-frequency signal and the low-frequency signal.
