Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application are capable of operation in sequences other than those illustrated or described herein, and that the terms "first," "second," etc. are generally used in a generic sense and do not limit the number of terms, e.g., a first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
The radio frequency circuit, the electronic device, the control method of the radio frequency circuit, and the readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
The wireless communication device may use two operating modes, frequency Division Duplex (FDD) and Time Division Duplex (TDD), to transmit and receive radio Frequency signals. In the FDD working mode, the transmitting and receiving frequencies are different, and the transmitting and receiving can be carried out simultaneously; in the TDD mode of operation, the frequency of transmission and reception is close, and the reception and transmission of radio frequency signals can only be performed in a time-sharing manner. Of course, in wireless communication, there are also frequency bands that only need to receive and not transmit, for example: and a B32 frequency band, which is used for performing downlink Carrier Aggregation (CA) on other frequency bands to improve downlink throughput.
In view of the fact that the frequency range of the B32 frequency band is greatly different from the frequency range of the MHB, the same antenna can be used to implement receiving and transmitting of two radio frequency signals in the FDD operating mode (receiving MHB signals and transmitting B32 signals, or transmitting MHB signals and B32 signals), but the requirement on the electromagnetic environment of the antenna is high, while the good electromagnetic environment of the electronic device in the prior art is rare, and it is difficult to find two installation locations with good electromagnetic environment on the electronic device to install a main set antenna and a diversity antenna respectively, therefore, in the related art, an antenna with good electromagnetic environment is usually selected from the electronic device as a main set antenna shared by B32 and MHB, and an MHB diversity antenna and a B32 diversity antenna are additionally provided, so as to ensure that the performance of the main diversity set antenna and the antenna of B32 can meet the requirement of the communication standard or the communication quality.
For example: as shown in fig. 1, taking a Long Term Evolution (LTE) wireless communication network as an example, the radio frequency path includes: the antenna comprises a radio frequency transceiver 10, a combiner 11, a power amplifier module 12, a B32 filter 13, an antenna switch 14, a diversity receiving module 15, a first antenna ANT0 and a second antenna ANT1. The main set receiving and Transmitting (TRX) of the MHB and the main set receiving (PRX) of the B32 share the first antenna ANT0, and the first antenna ANT0 is respectively connected to the MHB TRX radio frequency path and the B32PRX radio frequency path through the combiner 11, so as to filter or amplify the TRX signal of the MHB through the power amplifier module 12 in the MHB TRX radio frequency path and filter the B32PRX signal through the B32 filter 13 in the B32PRX radio frequency path, and the diversity receiving module 15 is used for filtering the MHB DRX received through the second antenna ANT 1; in addition, in some application scenarios, the electronic device needs to switch an antenna for transmitting a Signal (for example, sounding Reference Signal (SRS)) for antenna transmission, at this time, the MHB TRX may be switched to the second antenna ANT1 through the antenna switch 14, and at this time, the B32PRX Signal received through the first antenna ANT0 may still be filtered through the B32 filter 13 in the B32PRX radio frequency path, so as to ensure the receiving performance of the B32PRX Signal.
As shown in fig. 1, in the related art, a radio frequency path needs to be separately provided for a B32PRX, so as to perform filtering processing on a B32PRX signal by using a B32 filter in the radio frequency path, but the B32PRX signal cannot be filtered by using a power amplifier module 12 in an MHB TRX radio frequency path, where the B32 filter is integrated in the power amplifier module 12, so that electronic components in a radio frequency circuit are added, and the structure of the radio frequency circuit is complicated.
In the embodiment of the application, the B32PRX signal is filtered by multiplexing the power amplifier module in the MHB TRX radio frequency channel or the diversity receiving module in the MHB DRX radio frequency channel, so that an independent radio frequency channel does not need to be set for the B32PRX, the circuit structure of the radio frequency circuit can be simplified, the insertion loss of too many electronic components to the radio frequency signal is reduced, and the communication quality of the radio frequency circuit can be improved.
Referring to fig. 2, a circuit diagram of a radio frequency circuit according to an embodiment of the present invention is shown in fig. 1, where the radio frequency circuit includes: a radio frequency transceiver 21, a filtering module 22, a diversity receiving module 23, a switching module 24, an antenna switch 25, a first antenna 26 and a second antenna 27.
A main set transmitting terminal (TX 0_ MB and TX0_ HB shown in fig. 3) of the radio frequency transceiver 21 is connected to a first terminal of the filtering module 22, a first main set receiving terminal (one of PRx0 to PRx3 shown in fig. 3) of the radio frequency transceiver 21 is connected to a second terminal of the filtering module 22, and a third terminal of the filtering module 22 is connected to one of the first antenna 26 and the second antenna 27 through the antenna switch 25;
a first diversity receiving end (DRx 0 to DRx3 shown in fig. 3) of the rf transceiver 21 is connected to a first end of the diversity receiving module 23, and a second end of the diversity receiving module 23 is connected to the other of the first antenna 26 and the second antenna 27 through the antenna switch 25;
a first end of the switching module 24 is connected to a second main set receiving end (different from the first main set receiving end in PRx0 to PRx3 shown in fig. 3) of the radio frequency transceiver 21, a second end of the switching module 24 is connected to a fourth end of the filtering module 22, and a third end of the switching module 24 is connected to a third end of the diversity receiving module 23;
the radio frequency circuit comprises a first working state and a second working state;
under the condition that the radio frequency circuit is in the first working state, the antenna switch 25 connects the third end of the filtering module 22 with the first antenna 26, and the first end of the switching module 24 is communicated with the second end of the switching module 24, so as to transmit a main set transmitting signal of a first working frequency band through the first antenna 26 and receive a main set receiving signal of a second working frequency band;
under the condition that the radio frequency circuit is in the second working state, the antenna switch 25 connects the third end of the filtering module 22 with the second antenna 27, and the first end of the switching module 24 is communicated with the third end of the switching module 24, so as to transmit a main set transmitting signal of the first working frequency band through the second antenna 27, and receive a main set receiving signal of the second working frequency band through the first antenna 26.
In an implementation, the filtering module 22 and the diversity receiving module 23 may respectively integrate a plurality of filters to respectively perform filtering processing on radio frequency signals of a plurality of frequency bands, and the filtering module 22 further integrates a power amplifier to perform power amplification processing on the radio frequency signal to be transmitted through the power amplifier. Therefore, the fourth end of the filter module 22 can be understood as: and an output of the filter in the filtering module 22, which is adapted to filter the rf signal at the second operating frequency. Accordingly, the third end of the diversity receiving module 23 can also be understood as: and an output terminal of the filter in the diversity receiving module 23, which is adapted to filter the rf signal of the second operating frequency.
Optionally, the signal transmitting frequency or the signal receiving frequency in the first operating band is 1710MHz to 2690MHz (i.e., the frequency range of MHB), and the signal receiving frequency in the second operating band is 1452MHz to 1496MHz (i.e., the frequency range of B32).
It should be noted that, the first operating frequency and the second operating frequency are frequencies in different frequency bands, for convenience of description, in the following embodiment, only the first operating frequency is an MHB frequency, and the second operating frequency is a B32 frequency, which is taken as an example for illustration, it is only necessary to ensure that the first operating frequency and the second operating frequency do not generate large mutual interference when receiving and transmitting on the same antenna, and the first operating frequency and the second operating frequency are not specifically limited herein.
In an implementation, the MHB signals may be subjected to primary set reception and transmission, the B32 signals may be subjected to primary set reception, and the MHB signals may be subjected to diversity reception, with the MHB signals being subjected to a 1-way transmission path and 2-way reception path (1T 2R) communication scheme, and the B32 signals being subjected to a 2-way reception path (0T 2R) communication scheme.
In addition, the antenna switch 25 is used for switching the antenna, and in implementation, the antenna switch 25 may be a double-pole double-throw switch, and the structure thereof is the same as that of the antenna switch in the prior art, and is not described herein again.
In a normal application scenario (i.e. the first operating state), the antenna switch 25 may default to connect the MHB TRX to the first antenna 26, that is, to connect the third terminal of the filtering module 22 to the first antenna 26; correspondingly, at this time, the antenna switch 25 also connects the MHB DRX to the second antenna 27, that is, the second end of the diversity reception module to the second antenna 27.
At this time, the switching module 24 connects the fourth end of the filtering module 22 with the second main set receiving end of the rf transceiver 21, so as to perform main set receiving and transmitting on the MHB signal through the first antenna 26, and perform main set receiving on the B32 signal, so that the MHB TRX rf path formed by the rf transceiver 21, the filtering module 22 and the antenna switch 25 is shared with the B32PRX rf path. In other words, compared with the radio frequency circuit in the related art as shown in fig. 1, in the embodiment of the present application, in the case that the MHB TRX is communicated with the first antenna 26, the B32PRX and the MHB TRX share one radio frequency path, so that a separate radio frequency path and combiner do not need to be provided for the B32PRX, thereby simplifying the complexity of the radio frequency circuit.
Of course, in the first operating state, the MHB DRX radio frequency path formed by the radio frequency transceiver 21, the diversity reception module 23, and the antenna switch 25 is communicated with the second antenna to communicate the MHB DRX with the second antenna 27, so as to perform diversity reception on the MHB signal through the second antenna 27.
In addition, when the antenna is switched, the antenna switch 25 may switch the MHB TRX to communicate with the second antenna 27, that is, the third terminal of the filtering module 22 communicates with the second antenna 27; accordingly, at this time, the antenna switch 25 also communicates the MHB DRX with the first antenna 26, that is, the second end of the diversity receiving module with the first antenna 26.
At this time, since only the electromagnetic environment around the first antenna 26 supports the compatibility between B32 and MHB, the switching module 24 connects the third end of the diversity receiving module 23 to the second main set receiving end of the radio frequency transceiver 21, so as to perform diversity reception on MHB signals through the first antenna 26 and perform main set reception on B32 signals; and the second antenna 27 is used for carrying out main set receiving and transmitting on the MHB signals, so that an MHB DRX radio frequency path formed by the radio frequency transceiver 21, the diversity receiving module 23 and the antenna switch 25 is shared with a B32PRX radio frequency path, and the radio frequency paths among the radio frequency transceiver 21, the power amplifier module 22 and the antenna switch 25 are MHB TRX radio frequency paths. In other words, compared with the radio frequency circuit in the related art as shown in fig. 1, in the embodiment of the present application, in the case that the MHB TRX is communicated with the first antenna 26, the B32PRX and the MHB DRX share one radio frequency path, so that a separate radio frequency path and combiner do not need to be provided for the B32PRX, thereby simplifying the complexity of the radio frequency circuit.
It should be noted that, if the second main set receiving end of the radio frequency transceiver 21 is not switched to the third end of the diversity receiving module 23 by the switching module 24 after the MHB TRX antenna is switched to the second antenna 27, the MHB TRX and B32PRX are both communicated with the second antenna 27, and the magnetic field environment around the second antenna 27 is complex, so that the compatibility of the MHB TRX and B32PRX is not supported, so that the antenna performance of the second antenna 27 is poor, that is, the scheme cannot be used normally.
In an implementation, the switching module 24 may be a switch, for example: as shown in fig. 3, in the single-pole double-throw switch, the first end of the switching module 24 is a fixed end of the single-pole double-throw switch, the fixed end is connected to the second main set receiving end of the radio frequency transceiver 21, the second end and the third end of the switching module 24 are two active ends of the single-pole double-throw switch respectively, and the two active ends are connected to the fourth end of the filtering module 22 and the third end of the diversity receiving module 23 respectively, so that the second main set receiving end of the radio frequency transceiver 21 can be switched to the filtering module 22 or the diversity receiving module 23 correspondingly connected to the active end by controlling the switch of the single-pole double-throw switch to any one of the active ends.
Of course, in a specific implementation, the switching module 24 may also be other circuit structures or electronic components, and is not limited in this respect.
In addition, as shown in the circuit diagram of fig. 2, the circuit structure which is partially the same as that of the radio frequency circuit in the prior art is omitted, for example: in the filtering module, the method may specifically include: the rf receiving path further includes a power amplifier, a filter, a switch, etc., and the rf receiving path further includes a power amplifier, etc., which can refer to the rf circuit in the prior art and is not specifically described herein.
Optionally, as shown in fig. 3, the radio frequency circuit further includes: a third antenna 28 and a filter 29, where the third antenna 28 is connected to a second diversity receiving end (different from the first diversity receiving end, for example, one of DRx0 to DRx3 shown in fig. 3) of the radio frequency transceiver 21 through the filter 29, and the filter 29 is configured to filter the radio frequency signal in the second operating frequency band.
In this embodiment, the radio frequency signal of the second operating frequency band is diversity-received by the third antenna 28, and the filter 29 is used to filter the diversity-received signal of the second operating frequency band, that is, on the basis of the radio frequency circuit shown in fig. 2, a B32DRX radio frequency path and a B32DRX antenna are added to implement diversity reception of B32, so as to improve the reception performance of the B32 signal.
Optionally, as shown in fig. 3, the radio frequency circuit further includes: a first receiving module 210 and a second receiving module 211;
the first main set receiving end of the radio frequency transceiver 21 is connected to the second end of the filtering module 22 through the first receiving module 210, and the first end of the switching module 24 is connected to the second main set receiving end of the radio frequency transceiver 21 through the first receiving module 210;
the first diversity receiving end of the rf transceiver 21 is connected to the first end of the diversity receiving module 23 through the second receiving module 211.
The first receiving module 210 and the second receiving module 211 include: the power amplifier comprises a first power amplifier used for carrying out power amplification processing on received signals in a first working frequency band and a second power amplifier used for carrying out power amplification processing on the received signals in a second working frequency band.
Of course, the first receiving module 210 and the second receiving module 211 may further include a matching circuit and an output interface for connecting with a corresponding port of the rf transceiver 21, so as to implement impedance matching of the received signal through the first receiving module 210 and the second receiving module 211, and transmit the signal to a signal receiving end of the rf transceiver 21.
Further, as shown in fig. 3, the filter 28 is also connected to the second diversity receiving end of the rf transceiver 21 through the second receiving module 211.
In this embodiment, the first receiving module 210 and the second receiving module 211 are used to connect the rf receiving path and the rf transceiver 21.
In practical applications, the power amplifier and the like in the radio frequency receiving path may be disposed at other positions, and the radio frequency receiving path may further include other electronic components such as a coupler, which is not specifically limited herein.
In this embodiment of the application, when the radio frequency circuit is in the first operating state, the antenna switch connects the third end of the filtering module with the first antenna, and the first end of the switching module is communicated with the second end of the switching module, so as to transmit a main set transmitting signal of a first operating frequency band through the first antenna and receive a main set receiving signal of a second operating frequency band; and under the condition that the radio frequency circuit is in the second working state, the antenna switch connects the third end of the filtering module with the second antenna, and the first end of the switching module is communicated with the third end of the switching module so as to transmit a main set transmitting signal of a first working frequency band through the second antenna and receive a main set receiving signal of a second working frequency band through the first antenna. Therefore, when the main set transmitting signal of the first working frequency band is transmitted through the first antenna, the filtering module can be used for filtering the main set receiving signal of the second working frequency band; when the main set transmitting signal of the first working frequency band is transmitted through the second antenna, the main set receiving signal of the second working frequency band can be filtered by using the diversity receiving module, so that a combiner and a main set receiving radio frequency channel of the second working frequency band do not need to be arranged independently, and the structure of the radio frequency circuit is simplified.
