Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.
In the 4G to 5G evolution strategy, the ENDC (LTE NR Double Connect,4G and 5G dual connectivity technology) scheme will become an important 5G coverage scheme for a considerable period of time, i.e. the scheme with 4G and 5G dual connectivity guarantees signal continuity in 5G signal instability or uncovered areas.
It can be seen that when the ENDC is combined, the 4G and 5G dual-connection, i.e. the radio frequency signals in the LTE (4G) radio frequency band and in the NR (5G) radio frequency band are transmitted simultaneously. At this time, the radio frequency signal in the LTE radio frequency band and the radio frequency signal in the NR radio frequency band are respectively amplified on different power amplifiers, and at this time, the radio frequency circuit needs two antenna radiators; when only the LTE radio frequency band or the NR radio frequency band works, the amplification is only performed on one power amplifier, and only one antenna radiator is needed by the radio frequency circuit.
Therefore, referring to fig. 1, fig. 1 is a schematic structural diagram of a related art rf circuit. A radio frequency circuit 100 is disclosed in the related art. The radio frequency circuit 100 comprises at least a radio frequency transceiver 10, a first power amplifier 20, a second power amplifier 30, a first antenna radiator 40, a second antenna radiator 50.
The first power amplifier 20 and the second power amplifier 30 are electrically connected to the radio frequency transceiver 10, respectively. The first power amplifier 20 has a first output port 21 and a second output port 22, and the first output port 21 and the second output port 22 are electrically connected to the first antenna radiator 40. The second power amplifier 30 has a third output port 31, which third output port 31 is electrically connected to the second antenna radiator 50.
The first power amplifier 20 may be operated and the second power amplifier 30 may be deactivated when the rf circuit 100 only supports rf signals in the LTE rf band or the NR rf band. After the first power amplifier 20 amplifies the radio frequency signal in the LTE radio frequency band, the amplified radio frequency signal in the LTE radio frequency band is transmitted to the first antenna radiator 40 through the first output port 21; the first power amplifier 20 amplifies the rf signal in the NR rf band, and the amplified rf signal in the NR rf band is transmitted to the first antenna radiator 40 through the second output port 22.
The radio frequency circuit 100 supports the ENDC combination in which the first power amplifier 20 and the second power amplifier 30 operate simultaneously. For example, after the first power amplifier 20 amplifies the radio frequency signal in the LTE radio frequency band, the amplified radio frequency signal in the LTE radio frequency band is transmitted to the first antenna radiator 40 through the first output port 21, and after the second power amplifier 30 amplifies the radio frequency signal in the NR radio frequency band, the amplified radio frequency signal in the NR radio frequency band is transmitted to the second antenna radiator 50 through the third output port 31. For another example, the first power amplifier 20 amplifies the rf signal in the NR rf band, the amplified rf signal in the NR rf band is transmitted to the first antenna radiator 40 through the second output port 22, the second power amplifier 30 amplifies the rf signal in the LTE rf band, and the amplified rf signal in the LTE rf band is transmitted to the second antenna radiator 50 through the third output port 31.
The radio frequency circuit 100 further includes a first filter 60, a second filter 70, and a third filter 80. The first filter 60 is electrically connected to the first output port 21 of the first power amplifier 20 and the first antenna radiator 40, the second filter 70 is electrically connected to the second output port 22 of the first power amplifier 20 and the first antenna radiator 40, and the third filter 80 is electrically connected to the third output port 31 of the second power amplifier 30 and the second antenna radiator 50.
As can be seen, in the related art rf circuit 100, each power amplifier corresponds to an antenna radiator to support signal transmission in multiple states. Further, each power amplifier corresponds to a filter for filtering the transmitted rf signal. That is, the radio frequency circuit 100 includes at least two antenna radiators and three filters, so that the transmission of radio frequency signals in the LTE radio frequency band or radio frequency signals in the NR radio frequency band and the transmission of ENDC radio frequency signals can be realized.
However, current electronic devices are designed to be lighter and thinner, so that the space that the radio frequency circuit can occupy is reduced. It is a difficult problem how to implement multiplexing of electronic components within the radio frequency circuit to reduce the space occupied by the radio frequency circuit in the electronic device.
Therefore, the utility model provides a radio frequency circuit and an electronic device, wherein the radio frequency circuit can realize multiplexing of an antenna radiator so as to reduce the space occupied by the radio frequency circuit in the electronic device. Specific analyses are performed below in conjunction with the accompanying drawings.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a radio frequency circuit according to an embodiment of the utility model.

The radio frequency circuit 200 includes a radio frequency transceiver 210, a first power amplifier 220, an antenna radiator 230, a second power amplifier 240, and a selector switch 250. The first power amplifier 220 is electrically connected to the rf transceiver 210, the antenna radiator 230 is electrically connected to the first power amplifier 220, the second power amplifier 240 is electrically connected to the rf transceiver 210, and the selection switch 250 is electrically connected to the first power amplifier 220, the second power amplifier 240, and the antenna radiator 230, respectively.

The at least one of the LTE radio frequency band and the NR radio frequency band includes the following: only the LTE radio frequency band; only the NR radio frequency band; LTE radio frequency band and NR radio frequency band.
When the rf circuit 200 only needs to support the rf signal in the LTE rf band or the NR rf band, the selection switch 250 connects the first power amplifier 220 and the antenna radiator 230, and the rf signal in the LTE rf band is amplified by the first power amplifier 220 and then transmitted to the antenna radiator 230, or the rf signal in the NR rf band is amplified by the first power amplifier 220 and then transmitted to the antenna radiator 230.

When the selection switch 250 connects the fourth output port 222 with the antenna radiator 230, in some cases, the third output port 221 may be used to transmit radio frequency signals in the LTE radio frequency band, and the fourth output port 222 may be used to transmit radio frequency signals in the NR radio frequency band; in other cases, the third output port 221 may be used to transmit radio frequency signals in the NR radio frequency band, and the fourth output port 222 may be used to transmit radio frequency signals in the LTE radio frequency band.
When the radio frequency circuit 200 needs to support the transmission of ENDC radio frequency signals, the selection switch 250 connects the second power amplifier 240 with the antenna radiator 230. Since the ENDC radio frequency signal is composed of radio frequency signals in the LTE radio frequency band and in the NR radio frequency band. The ENDC technology takes an LTE network as a main part and an NR network as an auxiliary part. On one hand, the method can fully utilize the 4G network which is developed and mature at present, save network deployment cost, on the other hand, the technical difficulty can be reduced, and the method can smoothly transition to the 5G network as soon as possible. Under the ENDC technology, all signaling is transmitted through the LTE network, while data can be transmitted through the LTE network or through the NR network.
In some cases, the first power amplifier 220 is configured to amplify a radio frequency signal in the LTE radio frequency band and transmit the amplified radio frequency signal in the LTE radio frequency band to the antenna radiator 230, and the second power amplifier 240 is configured to amplify a radio frequency signal in the NR radio frequency band and transmit the amplified radio frequency signal in the NR radio frequency band to the antenna radiator 230.

When the selection switch 250 connects the fourth output port 222 with the antenna radiator 230, in some cases, the third output port 221 may be used to transmit radio frequency signals in the LTE radio frequency band, and the output port of the second power amplifier 240 may be used to transmit radio frequency signals in the NR radio frequency band; in other cases, the third output port 221 may be used to transmit radio frequency signals in the NR radio frequency band, and the output port of the second power amplifier 240 may be used to transmit radio frequency signals in the LTE radio frequency band.

When the rf circuit 200 needs to support the transmission of ENDC rf signals, the moving end of the single pole double throw switch is electrically connected to the second stationary end to communicate with the second power amplifier 240 and the antenna radiator 230.
In some embodiments, the radio frequency circuit 200 further includes a first filter 260, the first filter 260 being electrically connected to the antenna radiator 230 and the selection switch 250. For example, when the selector switch 250 is a single pole double throw switch, the active end of the single pole double throw switch is connected to the first filter 260. The first filter 260 may filter noise of radio frequency signals in the LTE radio frequency band or the NR radio frequency band. The first filter 260 may be a diplexer.
The rf circuit 200 further includes a second filter 270, and the second filter 270 is electrically connected to the antenna radiator 230 and the first power amplifier 220, respectively. The second filter 270 may filter noise of radio frequency signals in the LTE radio frequency band or the NR radio frequency band. The second filter 270 may be a diplexer.
Therefore, in the related art, three filters are required to be set to filter the rf signal without setting the selection switch 250, but in the embodiment of the utility model, by setting the selection switch 250 in the rf circuit 200, only two filters are required to achieve the effect of three filters in the related art, that is, one filter is saved, on one hand, the space occupied by the rf circuit 200 is effectively reduced, and on the other hand, the cost can be reduced.

The first output port 211 is electrically connected to the first power amplifier 220, and the second output port 212 is electrically connected to the second power amplifier 240.
