As described in the background section, the insertion loss is large when transmitting antenna signals in the existing electronic devices.
In view of this, an embodiment of the present application provides an electronic device, as shown in fig. 1, the electronic device includes:

In an embodiment of the present application, the radio frequency circuit includes: the antenna comprises four radio frequency paths, each radio frequency path is connected with one antenna, namely the radio frequency paths correspond to the antennas one to one, wherein each radio frequency path at least comprises one through path, so that when the electronic equipment transmits antenna signals through the through paths, insertion loss caused by switching elements such as an electric switch and the like can not be introduced, the insertion loss when the through paths transmit the antenna signals is further reduced, and the quality of the antenna signals is improved.
It should be noted that, in the embodiment of the present application, one through path may be included in the four radio frequency paths, and two through paths or more through paths may also be included in the four radio frequency paths.
Specifically, on the basis of the foregoing embodiment, in an embodiment of the present application, the four radio frequency paths include a first radio frequency path, and the first radio frequency path is a through path, and in this embodiment, the first radio frequency path includes: it should be noted that, in the embodiment of the present application, the direct connection between the first radio frequency element 11 and the first antenna 21 means that there is no switch element on a radio frequency path between the first radio frequency element 11 and the first antenna 21.
In the above embodiment, if the electronic device is in the first communication mode, the first rf path is in the first operating frequency band to radiate the rf signal in the first operating frequency band. It should be noted that, in this embodiment of the present application, the first radio frequency element 11 is a signal transmitting element, which can not only transmit radio frequency signals, but also receive radio frequency signals, and therefore, in this embodiment of the present application, if the electronic device is in the first communication mode, the first radio frequency channel is in the first operating frequency band, and can also receive radio frequency signals of the first operating frequency band.
In this embodiment of the application, since the first rf path is a through path, when the first rf element 11 radiates or receives the rf signal in the first operating frequency band through the first rf path, no switch element is needed, the insertion loss is small, and the signal quality is good.
It should be noted that, in this embodiment of the application, if the electronic device is in the first communication mode, the first radio frequency path is in the first operating frequency band, the first radio frequency element 11 radiates the signal of the first operating frequency band and receives the signal of the first operating frequency band, which are operated in a time-sharing manner, that is, in the first time period, the first radio frequency element 11 radiates the signal of the first operating frequency band, and in the second time period, the first radio frequency element 11 receives the signal of the first operating frequency band, where the first time period and the second time period are different time periods and do not overlap.
Optionally, in this embodiment of the application, the first operating frequency band is 2496MHz to 2690MHz, that is, the first operating frequency band is an N41 frequency band, but this is not limited in this application, and is specifically determined as the case may be.

Since the first radio frequency element 11 is a signal transmitting element, in this embodiment of the application, if the electronic device is in the second communication mode supporting the fourth generation mobile communication technology, the first radio frequency path is in the second operating frequency band, and the electronic device may further receive the radio frequency signal in the second operating frequency band, so that the electronic device may implement receiving the radio frequency signal in the second operating frequency band in the second communication mode. Similarly, if the electronic device is in the second communication mode supporting the fourth generation mobile communication technology, the first radio frequency path is in the second working frequency band, and the first radio frequency element 11 may radiate and receive the radio frequency signal in the second working frequency band in a time-sharing manner when the first radio frequency element 11 may radiate the radio frequency signal in the second working frequency band through the first radio frequency path, or may receive the radio frequency signal in the second working frequency band through the first radio frequency path.
In this embodiment of the application, since the first rf path is a through path, when the first rf element 11 radiates or receives the rf signal in the second operating frequency band through the first rf path, no switching element is needed, so that the insertion loss is small and the signal quality is good.
It should be noted that, since the B41 of the second communication mode is the same as the N41 frequency band of the first communication mode, in an embodiment of the present application, the second operating frequency band is a B41 frequency band of the second communication mode, that is, the second operating frequency band and the first operating frequency band are the same frequency band.

It should be noted that, in the embodiment of the present application, the second rf element 12 is a signal receiving element, and therefore, the second rf element 12 is directly connected to the second antenna 22, that is, there is no switching element between the second rf element 12 and the second antenna 22, so that insertion loss when the second rf element 12 receives the rf signal of the first operating frequency band through the second rf path can be reduced, and signal quality can be improved.
Since the second rf component 12 is a signal receiving component and cannot directly transmit rf signals, in an embodiment of the present application, the rf circuit further includes: a single pole double throw switch (SPDT switch) 31, wherein the SPDT switch 31 is connected to the first rf component 11 and the second rf component 12, and is configured to set the second rf path to the first operating frequency band based on a base station feedback signal configuration if the electronic device is in the first communication mode, so as to radiate the rf signal in the first operating frequency band.
It should be noted that, in this embodiment of the application, configuring, based on a base station feedback signal, that the second radio frequency path is in the first operating frequency band, so as to radiate a radio frequency signal of the first operating frequency band, an operating process includes: receiving a base station feedback signal, configuring the second radio frequency path to be in the first working frequency band, and radiating a first instruction of a radio frequency signal of the first working frequency band, responding to the first instruction, controlling the single-pole double-throw switch 31 to be closed, so that the radio frequency signal of the first working frequency band output by the first radio frequency element 11 is input to the second radio frequency element 12, and then the second radio frequency element 12 is used to transmit the signal of the first working frequency band to the second antenna 22 through the second radio frequency path, and the signal is radiated out through the second antenna 22.

It should be noted that, since an auxiliary port is usually disposed in the radio frequency component, in an optional embodiment of the present application, on the basis of the foregoing embodiment, a port where the first radio frequency component 11 is connected to the single-pole double-throw switch 31 is an auxiliary port of the first radio frequency component 11, so that signal transmission between the first radio frequency component 11 and the second radio frequency component 12 can be achieved without modifying the structure of the first radio frequency component 11, thereby not increasing the cost of the electronic device. Optionally, in an embodiment of the present application, the auxiliary port of the first rf component 11 is an AUX port of the first rf component 11.
Similarly, the port of the second rf component 12 connected to the single-pole double-throw switch 31 is also an auxiliary port of the second rf component 12, and optionally, the auxiliary port of the second rf component 12 is an AUX port of the second rf component 12.

However, the present application is not limited thereto, and in other embodiments of the present application, the filtering element may also be located between the single-pole double-throw switch and the second rf element, as the case may be. Optionally, the filter element is a filter.
On the basis of any one of the foregoing embodiments, in an embodiment of the present application, the radio frequency circuit further includes: a third rf element 13, a third antenna 23, a fourth rf element 14, a fourth antenna 24, and a double-pole double-throw switch (DPDT switch) 32, where the double-pole double-throw switch 32 is respectively connected to the third rf element 13, the third antenna 23, the fourth rf element 14, and the fourth antenna 24, and is configured to form a third rf path or a fourth rf path based on a base station feedback signal if the electronic device is in the first communication mode.

The third rf element 13 is a signal transmitting element, and the fourth rf element 14 is a signal receiving element.
In a specific operation, in an embodiment of the present application, if the electronic device is in the first communication mode, the electronic device may utilize the third rf element 13 to transmit the rf signal in the first operating frequency band based on the base station feedback signal, and the rf signal in the first operating frequency band transmits the signal in the first operating frequency band to the third antenna 23 through a path between the third rf element 13 and the double-pole double-throw switch 32 and a path between the double-pole double-throw switch 32 and the third antenna 23, and is radiated by the third antenna 23. Accordingly, the third radio frequency path includes a path between the third radio frequency element 13 and the double pole double throw switch 32 and a path between the double pole double throw switch 32 and the third antenna 23.
In another embodiment of the present application, if the electronic device is in the first communication mode, the electronic device may transmit a radio frequency signal of a first operating frequency band by using the third radio frequency element 13 based on a base station feedback signal, and the radio frequency signal of the first operating frequency band transmits the signal of the first operating frequency band to the fourth antenna 24 through a path between the third radio frequency element 13 and the double-pole double-throw switch 32 and a path between the double-pole double-throw switch 32 and the fourth antenna 24, and radiates the signal through the fourth antenna 24. Correspondingly, the fourth radio frequency path includes a path between the third radio frequency element 13 and the double-pole double-throw switch 32 and a path between the double-pole double-throw switch 32 and the fourth antenna 24.
It should be noted that, in this embodiment of the application, if the electronic device is in the first communication mode, the third rf component 13 further receives, through the third rf path, the rf signal in the first operating frequency band output from the third antenna 23, or receives, through the fourth rf path, the rf signal in the first operating frequency band output from the fourth antenna 24.
On the basis of any of the foregoing embodiments, in an embodiment of the present application, if the electronic device is in the first communication mode, the fourth radio frequency element may also receive a radio frequency signal in the first operating frequency band. Specifically, the fourth rf device 14 may receive the rf signal of the first operating frequency band output by the third antenna 23 through a path between the fourth rf device 14 and the double-pole double-throw switch 32 and a path between the double-pole double-throw switch 32 and the third antenna 23, and may also receive the rf signal of the first operating frequency band output by the fourth antenna 24 through a path between the fourth rf device 14 and the double-pole double-throw switch 32 and a path between the double-pole double-throw switch 32 and the fourth antenna 24.
It should be noted that, in the above embodiment, when the electronic device is configured to receive a radio frequency signal in a first operating frequency band, the first radio frequency element 11, the second radio frequency element 12, the third radio frequency element 13, and the fourth radio frequency element 14 simultaneously receive the radio frequency signal in the first operating frequency band; when the electronic device is configured to radiate radio frequency signals of a first operating frequency band, generally only one signal transmitting element among the first radio frequency element 11, the second radio frequency element 12, the third radio frequency element 13, and the fourth radio frequency element 14 radiates the radio frequency signals of the first operating frequency band, such as the first radio frequency element 11 or the third radio frequency element 13, and therefore, in this embodiment of the present application, the electronic device needs to configure, based on a base station feedback signal, the radio frequency element and the radio frequency path that radiate the radio frequency signals of the first operating frequency band among the multiple radio frequency elements and the multiple radio frequency paths. However, this is not limited in this application, in other embodiments of the present application, when the electronic device is used to radiate a radio frequency signal in a first operating frequency band, two signal emitting elements among the first radio frequency element 11, the second radio frequency element 12, the third radio frequency element 13, and the fourth radio frequency element 14 may also radiate the radio frequency signal in the first operating frequency band outwards, for example, the first radio frequency element 11 or the third radio frequency element 13 may radiate the radio frequency signal in the first operating frequency band outwards, so as to increase a speed of the electronic device radiating the radio frequency signal in the first operating frequency band, where the specific case may be.
It should be further noted that, before sending the feedback signal to the electronic device, the base station may first obtain the signal transmission qualities of the four radio frequency paths, so as to send the radio frequency path with higher signal transmission quality to the electronic device as a target radio frequency path, so that the electronic device may radiate the radio frequency signal of the first operating frequency band by using the radio frequency path with higher signal transmission quality in the four radio frequency paths, and improve the quality of the radio frequency signal of the first operating frequency band radiated by the electronic device.
On the basis of any of the foregoing embodiments, in an embodiment of the present application, as shown in fig. 2, the radio frequency circuit further includes: a test socket 40 on each of the four rf paths for calibration and/or testing of the rf paths.

It should be noted that, in the above embodiment, the radio frequency signal of the first operating frequency band radiated by the second antenna 22 is derived from the first radio frequency element 11, in other embodiments of the present application, if the third radio frequency element 13 is a signal transmitting element, the radio frequency signal of the first operating frequency band radiated by the second antenna 22 may also be derived from the third radio frequency element 13, which is not limited in this application, and is determined as the case may be.
The electronic device provided in the embodiment of the present application is described below by taking the third radio frequency element 13 as a signal transmitting element, and taking the radio frequency signal of the first operating frequency band radiated by the second antenna 22 as an example, which is derived from the third radio frequency element 13.
As shown in fig. 3, in the embodiment of the present application, the four rf paths include a first rf path, and the first rf path is a through path, and in this embodiment, the first rf path includes: it should be noted that, in the embodiment of the present application, the direct connection between the first rf component 11 and the first antenna 21 means that there is no switch component on the rf path between the first rf component 11 and the first antenna 21.
In the above embodiment, if the electronic device is in the first communication mode, the first rf path is in the first operating frequency band to radiate the rf signal in the first operating frequency band. It should be noted that, in this embodiment of the present application, the first radio frequency element 11 is a signal transmitting element, which can not only transmit radio frequency signals, but also receive radio frequency signals, and therefore, in this embodiment of the present application, if the electronic device is in the first communication mode, the first radio frequency channel is in the first operating frequency band, and can also receive radio frequency signals of the first operating frequency band.
In this embodiment of the application, since the first rf path is a through path, when the first rf component 11 radiates or receives the rf signal in the first operating frequency band through the first rf path, no switching component is needed, the insertion loss is small, and the quality of the signal is good.
It should be noted that, in this embodiment of the application, if the electronic device is in the first communication mode, the first radio frequency path is in the first operating frequency band, the first radio frequency element 11 radiates the signal of the first operating frequency band and receives the signal of the first operating frequency band, which are operated in a time-sharing manner, that is, in the first time period, the first radio frequency element 11 radiates the signal of the first operating frequency band, and in the second time period, the first radio frequency element 11 receives the signal of the first operating frequency band, where the first time period and the second time period are different time periods and do not overlap.
Optionally, in this embodiment of the application, the first operating frequency band is 2496MHz to 2690MHz, that is, the first operating frequency band is an N41 frequency band, but this is not limited in this application, and is specifically determined as the case may be.
On the basis of any of the foregoing embodiments, in an embodiment of the present application, the different communication modes further include a second communication mode based on a fourth generation mobile communication technology, and if the electronic device is in the second communication mode supporting the fourth generation mobile communication technology, the first radio frequency path is in the second operating frequency band to radiate radio frequency signals in the second operating frequency band, so that the electronic device can implement radiation of the radio frequency signals in the second operating frequency band in the second communication mode.
Since the first radio frequency element 11 is a signal transmitting element, in this embodiment of the application, if the electronic device is in the second communication mode supporting the fourth generation mobile communication technology, the first radio frequency path is in the second operating frequency band, and the radio frequency signal in the second operating frequency band can also be received, so that the electronic device can receive the radio frequency signal in the second operating frequency band in the second communication mode.
