[0001] The present application relates to the field of terminal technology, and in particular to an electronic device and a control method. Background Art

[0002] Some electronic devices have communication functions. Electronic devices generate electromagnetic radiation during communication. When an electronic device transmits a signal, the electronic device controls the actual transmission power to be less than the transmission power obtained by the electronic device from the base station, so that the specific absorption ratio (SAR) value of the electromagnetic radiation of the antenna is smaller when the electronic device transmits a signal.

[0003] However, in a case where the actual transmission power of the electronic device is less than the transmission power obtained by the electronic device from the base station, there may be a problem of poor communication quality. Summary of the invention

[0004] The embodiment of the present application provides an electronic device and a control method, which are applied to the field of terminal technology. The electronic device includes a radio frequency chip, a first antenna and a second antenna, a phase shift unit is provided on the path between the radio frequency chip and the first antenna, and / or a phase shift unit is provided on the path between the radio frequency chip and the second antenna, and the first antenna and the second antenna are fed by the radio frequency chip, so that when both the first antenna and the second antenna are working, the phase shift unit provided can make the actual transmission power of the electronic device greater than or equal to the sum of the transmission power of the first antenna and the transmission power of the second antenna, thereby improving the communication quality of the electronic device. In addition, when the transmission power of the electronic device remains unchanged, the SAR value of each antenna when transmitting a signal through two antennas is smaller than the SAR value of the one antenna when transmitting a signal through one antenna.

[0005] In a first aspect, an embodiment of the present application proposes an electronic device, comprising: a radio frequency chip, a first antenna, and a second antenna. The radio frequency chip is used to feed the first antenna and the second antenna. When both the first antenna and the second antenna are working, there is a first phase shifter in the path between the first antenna and the radio frequency chip, and / or there is a second phase shifter in the path between the second antenna and the radio frequency chip. The first phase shifter and / or the second phase shifter are arranged so that when both the first antenna and the second antenna are working, the actual transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power, the first transmission power being the transmission power of the first antenna, and the second transmission power being the transmission power of the second antenna.

[0006] In this way, the communication quality of the electronic device can be improved, and the SAR value of each antenna can be reduced.

The second antenna is connected; the input end of the second LNA is connected to the second antenna, and the output end of the second LNA is connected to the RF chip; the second duplexer is connected between the output end of the second PA and the second antenna, and the second duplexer is also connected between the input end of the second LNA and the second antenna; the first phase shifter is connected between the first duplexer and the first antenna, and the second phase shifter is connected between the second duplexer and the second antenna; or, the first phase shifter is connected between the first duplexer and the output end of the first PA, and the second phase shifter is connected between the second duplexer and the output end of the second PA.

[0008] In this way, the electronic device can transmit a signal through a link consisting of a radio frequency chip, a first PA, a first duplexer and a first antenna, and / or a link consisting of a radio frequency chip, a second PA, a second duplexer and a second antenna. The electronic device can receive a signal through a link consisting of a radio frequency chip, a first LNA, a first duplexer and a first antenna, and / or a link consisting of a radio frequency chip, a second LNA, a second duplexer and a second antenna. In addition, the signal transmitted by the electronic device can be amplified by a power amplifier, and the signal received by the electronic device can be amplified by a low noise amplifier, so as to further improve the communication quality of the electronic device.

[0009] In a possible implementation manner, the first phase shifting unit is a phase shifter or includes an inductor and a capacitor. The second phase shifting unit is a phase shifter or includes an inductor and a capacitor.

[0010] In this way, flexible deployment and cost control of the phase shifting unit can be achieved.

[0012] In this way, the electronic device can transmit a signal through a link composed of a radio frequency chip, a third PA, a power divider, a third duplexer and a first antenna, and / or a link composed of a radio frequency chip, a third PA, a power divider, a fourth duplexer and a second antenna.

In addition, the signal transmitted by the electronic device can be amplified by a power amplifier, and the signal received by the electronic device can be amplified by a low noise amplifier, which can further improve the communication quality of the electronic device. The power of the signal output by the third PA can be distributed by the power divider, so that the sum of the transmission power of the first antenna and the transmission power of the second antenna is equal to the power of the signal output by the third PA, and the phase of the signal output by the two output ends of the power divider can be kept consistent, which can reduce the probability of phase shift before the signal to be transmitted is transmitted to the phase shift unit, thereby further improving the communication quality of the electronic device.

[0048] In order to clearly describe the technical solutions of the embodiments of the present application, some terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0049] 1. Total radiated power (TRP)

[0050] The TRP of an antenna can be understood as the average value of the radiated power of the antenna in all directions.

[0051] 2. Frequency-division duplex (FDD) mode and time-division duplex (TDD) mode

[0052] The FDD mode and the TDD mode are two duplex communication modes in the third generation mobile communication technology.

[0053] Among them, the FDD mode can be understood as the communication device uses one working frequency to transmit signals and another working frequency to receive signals. The transmission and reception of signals are performed simultaneously, and the one working frequency is different from the other working frequency. The FDD mode can also be understood as the downlink and uplink are separated in frequency.

[0054] The TDD mode can be understood as the communication device using one operating frequency to transmit and receive signals, and the transmission and reception of signals are not performed at the same time. The FDD mode can also be understood as the downlink and uplink are separated in time.

[0055] The communication device may include an electronic device and a base station. The electronic device may obtain a frequency band identifier of the base station from the base station. The electronic device may determine the duplex communication mode corresponding to the frequency band identifier of the base station from the correspondence between the frequency band identifier and the duplex communication mode. In this way, the electronic device may communicate with the base station using the duplex communication mode corresponding to the frequency band identifier of the base station.

[0056] 3. Other terms

[0057] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0058] In the embodiments of the present application, "at least one" refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0059] In the embodiment of the present application, "at..." may be the instant when a certain situation occurs, or may be a period of time after a certain situation occurs, and the embodiment of the present application does not specifically limit this. In addition, the display interface provided in the embodiment of the present application is only an example, and the display interface may also include more or less content.

[0060] When an electronic device transmits a communication signal through its antenna, electromagnetic radiation is generated at the location of the antenna. The magnitude of the electromagnetic radiation can be expressed by the specific absorption ratio (SAR) value. The greater the antenna transmission power, the greater the SAR value of the antenna. The smaller the antenna transmission power, the smaller the SAR value of the antenna.

[0061] In some implementations, in order to reduce the SAR value of the antenna, some electronic devices will control the actual transmission power of the antenna (or the actual transmission power of the electronic device) to be less than the transmission power obtained by the electronic device from the base station when transmitting signals through the antenna. Among them, the transmission power obtained by the electronic device from the base station can be understood as the transmission power required for the electronic device to transmit a signal when the electronic device communicates with the base station as notified or instructed by the base station. The actual transmission power of the electronic device is less than the transmission power obtained by the electronic device from the base station, which can be understood as the electronic device is not transmitting at the maximum power.

[0062] The greater the actual transmission power of the electronic device, the better the communication quality of the electronic device. The smaller the actual transmission power of the electronic device, the worse the communication quality of the electronic device. Therefore, when the actual transmission power of the electronic device is less than the transmission power obtained by the electronic device from the base station, there may be a problem of poor communication quality.

[0063] In view of this, an embodiment of the present application proposes an electronic device, including a radio frequency chip, a first antenna, and a second antenna. A phase shift unit is provided on the path between the radio frequency chip and the first antenna, and / or a phase shift unit is provided on the path between the radio frequency chip and the second antenna. The first antenna and the second antenna are fed by the radio frequency chip. In this way, when both the first antenna and the second antenna are working, the phase shift unit provided can make the actual transmission power of the electronic device greater than or equal to the sum of the transmission power of the first antenna and the transmission power of the second antenna, thereby improving the communication quality of the electronic device. In addition, when the transmission power of the electronic device remains unchanged, the SAR value of each antenna when transmitting a signal through two antennas is smaller than the SAR value of the one antenna when transmitting a signal through one antenna.

[0064] Figure 1 A circuit diagram of an electronic device provided in an embodiment of the present application is shown.

[0065] like Figure 1 As shown, the electronic device includes a radio frequency integrated circuit (RFIC) 101, a first antenna 102 and a second antenna 103. The electronic device may also include a phase shift unit or two phase shift units. Figure 1 The first phase shifting unit 104 or the second phase shifting unit 105 is shown.

[0066] In the case where the electronic device includes one phase shifting unit, the circuit of the electronic device may be the following circuit one or circuit two.

[0067] In the case where the electronic device includes two phase shifting units, the circuit of the electronic device may be the following circuit three.

[0068] Circuit 1: The RF chip 101 is connected to the first antenna 102 and the second antenna 103 respectively. The first phase shift unit 104 is connected between the RF chip 101 and the first antenna 102. There is no phase shift unit between the RF chip 101 and the second antenna 103.

[0069] When the transmission power obtained by the electronic device from the base station is greater than a preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can simultaneously transmit signals through the link formed by the RF chip 101, the first phase shifter 104 and the first antenna 102, and the link formed by the RF chip 101 and the second antenna 103.

[0070] The transmission power of the first antenna 102 may be a first transmission power. The transmission power of the second antenna 103 may be a second transmission power. The transmission power obtained by the electronic device from the base station is equal to the sum of the transmission power of the first antenna 102 and the transmission power of the second antenna 103.

[0071] When the RF chip 101 feeds the first antenna 102 and the second antenna 103 at the same time, the first phase shifter 104 can phase shift the signal of the link formed by the RF chip 101, the first phase shifter 104 and the first antenna 102, so that the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power.

[0072] In this way, the communication quality of the electronic device can be improved. In addition, by allocating the transmission power to the first antenna 102 and the second antenna 103 for transmission, the SAR value of the first antenna 102 can be small, and the SAR value of the second antenna 103 can also be small.

[0073] It can be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 at the same time, the electronic device can simultaneously receive signals through the link formed by the RF chip 101, the first phase shifter 104 and the first antenna 102, and the link formed by the RF chip 101 and the second antenna 103.

[0074] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting the signal through one antenna is also small due to the small transmission power. Therefore, the RF chip 101 can feed the first antenna 102 to transmit the signal through the link formed by the RF chip 101, the first phase shift unit 104 and the first antenna 102, and can also receive the signal through the link formed by the RF chip 101, the first phase shift unit 104 and the first antenna 102; or, the RF chip 101 can feed the second antenna 103 to transmit the signal through the link formed by the RF chip 101 and the second antenna 103, and can also receive the signal through the link formed by the RF chip 101 and the second antenna 103.

[0075] For ease of understanding, the principle that the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power when the RF chip 101 simultaneously feeds the first antenna 102 and the second antenna 103 is described below. It can be understood that when the electronic device transmits a signal only through the first antenna 102, the transmission power of the electronic device is equal to the transmission power of the first antenna 102. When the electronic device transmits a signal only through the second antenna 103, the transmission power of the electronic device is equal to the transmission power of the second antenna 103.

[0076] For example, the transmission power of the antenna is TRP, the electronic device transmits the signal only through the first antenna 102 and the transmission power of the electronic device is TRP 1 The electronic device transmits signals only through the second antenna 103 and the transmission power of the electronic device is TRP 2 For example, when the electronic device transmits signals simultaneously through the link formed by the RF chip 101 and the first antenna 102, and the link formed by the RF chip 101 and the second antenna 103, the transmission power TRP of the electronic device is 1+2 Satisfies the following formula (1):

[0077]

[0078] The derivation process of formula (1) is as follows:

[0079]

[0080] Among them, A1 is the voltage fed by the electronic device to the first antenna 102 , and A1 can represent the amplitude of the signal transmitted by the first antenna 102 . The directivity pattern of the first antenna 102 may be represented. It can also represent the energy distribution or electric field around the first antenna 102. θ and A2 is the voltage fed by the electronic device to the second antenna 103, and A2 can represent the amplitude of the signal transmitted by the second antenna 103. The directivity pattern of the second antenna 103 may be represented. It can also represent the energy distribution or electric field around the second antenna 103. Integral. e is an irrational number. j can represent an imaginary number. δ is the phase difference between the signal transmitted by the first antenna 102 and the signal transmitted by the second antenna 103. * represents conjugate. Real can represent gain.

[0081] Because A1, A2, and are all greater than 0. As shown in formula (1), the phase difference between the signal transmitted by the first antenna 102 and the signal transmitted by the second antenna 103 can be controlled so that e -jδ ≥0, which makes TRP 1+2 ≥TRP 1 +TRP 2 .

[0082] Therefore, as shown in the circuit 1, when the RF chip 101 feeds the first antenna 102 and the second antenna 103 at the same time, the first phase shift unit 104 performs phase shift on the signal of the link formed by the RF chip 101, the first phase shift unit 104 and the first antenna 102, so that e -jδ ≥0, thereby making the transmission power of the electronic device greater than or equal to the sum of the first transmission power and the second transmission power.

[0083] Circuit 2: The RF chip 101 is connected to the first antenna 102 and the second antenna 103 respectively. The second phase shift unit 105 is connected between the RF chip 101 and the second antenna 103. There is no phase shift unit between the RF chip 101 and the first antenna 102.

[0084] When the transmission power obtained by the electronic device from the base station is greater than a preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can simultaneously transmit signals through the link formed by the RF chip 101 and the first antenna 102, and the link formed by the RF chip 101 and the second antenna 103.

[0085] When the RF chip 101 feeds the first antenna 102 and the second antenna 103 at the same time, the second phase shift unit 105 can phase shift the signal of the link formed by the RF chip 101, the second phase shift unit 105 and the second antenna 103, so that the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power.

[0086] When the transmission power obtained by the electronic device from the base station is greater than a preset value, the specific implementation principle and technical effect of the electronic device transmitting signals through the first antenna 102 and the second antenna 103 in circuit two are similar to the specific implementation principle and technical effect of the electronic device transmitting signals through the first antenna 102 and the second antenna 103 in circuit one, and are not repeated here.

[0087] It should be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 at the same time, the electronic device can simultaneously receive signals through the link formed by the RF chip 101 and the first antenna 102, and the link formed by the RF chip 101 and the second antenna 103.

[0088] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting the signal through one antenna is also small due to the small transmission power. Therefore, the RF chip 101 can feed the first antenna 102 to transmit the signal through the link formed by the RF chip 101 and the first antenna 102, and can also receive the signal through the link formed by the RF chip 101 and the first antenna 102; or, the RF chip 101 can feed the second antenna 103 to transmit the signal through the link formed by the RF chip 101 and the second antenna 103, and can also receive the signal through the link formed by the RF chip 101 and the second antenna 103.

[0089] Circuit 3: The RF chip 101 is connected to the first antenna 102 and the second antenna 103 respectively. The first phase shift unit 104 is connected between the RF chip 101 and the first antenna 102. The second phase shift unit 105 is connected between the RF chip 101 and the second antenna 103.

[0090] When the transmission power obtained by the electronic device from the base station is greater than a preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can simultaneously transmit signals through the link formed by the RF chip 101, the first phase shift unit 104 and the first antenna 102, and the link formed by the RF chip 101, the second phase shift unit 105 and the second antenna 103.

[0091] In the case where the RF chip 101 feeds the first antenna 102 and the second antenna 103 at the same time, the first phase shift unit 104 and the second phase shift unit 105 can make the phase difference between the signal transmitted by the link composed of the RF chip 101, the first phase shift unit 104 and the first antenna 102 and the signal transmitted by the link composed of the RF chip 101, the second phase shift unit 105 and the second antenna 103 satisfy e -jδ ≥0, thereby making the transmission power of the electronic device greater than or equal to the sum of the first transmission power and the second transmission power.

[0092] In this way, the communication quality of the electronic device can be improved and the SAR value of each antenna can be reduced.

[0093] It can be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 at the same time, the electronic device can also simultaneously receive signals through the link formed by the RF chip 101, the first phase shifter 104 and the first antenna 102, and the link formed by the RF chip 101, the second phase shifter 105 and the second antenna 103.

[0094] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting the signal through one antenna is also small due to the small transmission power. Therefore, the RF chip 101 can feed the first antenna 102 to transmit the signal through the link formed by the RF chip 101, the first phase shift unit 104 and the first antenna 102, and can also receive the signal through the link formed by the RF chip 101, the first phase shift unit 104 and the first antenna 102.

[0095] Alternatively, when the transmission power obtained by the electronic device from the base station is less than or equal to a preset value, the RF chip 101 can feed the second antenna 103 to transmit signals through the link formed by the RF chip 101, the second phase shift unit 105 and the second antenna 103, and can also receive signals through the link formed by the RF chip 101, the second phase shift unit 105 and the second antenna 103.

[0096] It can be understood that the duplex communication mode in which the electronic device communicates with the base station may include an FDD mode or a TDD mode.

[0097] In order to facilitate the understanding of the electronic device provided in the embodiment of the present application, Figure 2-Figure 8 , a circuit of an electronic device when the duplex communication mode of the electronic device and the base station is the FDD mode is described. Fig. 9 , a circuit of an electronic device when a duplex communication mode of the electronic device and a base station is a TDD mode is described.

[0098] Exemplarily, for a situation where the duplex communication mode between the electronic device and the base station is the FDD mode, Figure 2 Another circuit diagram of an electronic device provided in an embodiment of the present application is shown.

[0099] like Figure 2 As shown, in Figure 1Based on the embodiment, the electronic device further includes a first power amplifier (PA) 201 , a first low noise amplifier (LNA) 203 , a second PA 204 , a second LNA 206 , a first duplexer 202 and a second duplexer 205 .

[0100] The input end of the first PA 201 is connected to the RF chip 101, and the output end of the first PA 201 is connected to the first antenna 102. The input end of the first LNA 203 is connected to the first antenna 102, and the output end of the first LNA 203 is connected to the RF chip. The first duplexer 202 is connected between the output end of the first PA 201 and the first antenna 102, and the first duplexer 202 is also connected between the input end of the first LNA 203 and the first antenna 102.

[0101] The input end of the second PA 204 is connected to the RF chip, and the output end of the second PA 204 is connected to the second antenna 103. The input end of the second LNA 206 is connected to the second antenna 103, and the output end of the second LNA 206 is connected to the RF chip. The second duplexer 205 is connected between the output end of the second PA 204 and the second antenna 103, and the second duplexer 205 is also connected between the input end of the second LNA 206 and the second antenna 103.

[0102] Since the electronic device may include the first phase shift unit 104 and / or the second phase shift unit 105. Therefore, in the embodiment of the present application, the first phase shift unit 104 may be deployed in the following manner: the first phase shift unit 104 is connected between the first duplexer 202 and the first antenna 102, such as Figure 2 Alternatively, the first phase shift unit 104 is connected between the first duplexer 202 and the output end of the first PA 201, as shown in FIG. Figure 6 The deployment mode of the first phase shifting unit 104 is shown. For ease of understanding, Figure 6 This will be described later.

[0103] The second phase shift unit 105 may be deployed in a manner as follows: the second phase shift unit 105 is connected between the second duplexer 205 and the second antenna 103, such as Figure 2 Alternatively, the second phase shifter 105 is connected between the output ends of the second duplexer 205 and the second PA 204, as shown in FIG. Figure 6 The deployment manner of the second phase shifting unit 105 is shown.

[0104] Optionally, the first phase shift unit 104 and the second phase shift unit 105 can be integrated into the RF chip 101, so that the signal input to the first PA 201 can be a phase-shifted signal. The signal input to the second PA 204 can also be a phase-shifted signal.

[0105] Exemplarily, when the electronic device includes the first phase shift unit 104 but does not include the second phase shift unit 105, the electronic device may include the following circuit 4.

[0106] When the electronic device includes the first phase shift unit 104 but does not include the second phase shift unit 105 , the electronic device may include the following circuit five.

[0107] When the electronic device includes the first phase shift unit 104 and the second phase shift unit 105, the electronic device may include the following circuit 6.

[0108] Taking the deployment mode in which the first phase shifting unit 104 is connected between the first duplexer 202 and the first antenna 102, and the second phase shifting unit 105 is connected between the second duplexer 205 and the second antenna 103 as an example, the following is combined with Figure 2 , Circuit 4, Circuit 5 and Circuit 6 are explained respectively.

[0109] Circuit Four:

[0110] like Figure 2 As shown, the circuit 4 may include the following two RF transmission links:

[0111] The link L21 is formed by the RF chip 101 , the first PA 201 , the first duplexer 202 , the first phase shifter 104 and the first antenna 102 .

[0112] The link L22 is formed by the RF chip 101 , the second PA 204 , the second duplexer 205 and the second antenna 103 .

[0113] like Figure 2 As shown, the circuit four may also include the following two RF receiving links:

[0114] The link L23 is formed by the RF chip 101 , the first LNA 203 , the first duplexer 202 , the first phase shifter 104 and the first antenna 102 .

[0115] The link L24 is formed by the RF chip 101 , the second LNA 206 , the second duplexer 205 and the second antenna 103 .

[0116] When the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can transmit signals through the link L21 and the link L22 at the same time, and the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power. The specific implementation principle and technical effect are the same as Figure 1 The specific implementation principle and technical effect of transmitting signals when the first antenna 102 and the second antenna 103 are fed simultaneously in the circuit 1 of the embodiment are similar and will not be repeated here. It should be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 simultaneously, the electronic device can receive signals through the link L23 and the link L24 at the same time.

[0117] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting the signal through one antenna is also small due to the small transmission power. The RF chip 101 can feed the first antenna 102 to transmit the signal through the link L21 and receive the signal through the link L23. Alternatively, when the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the RF chip 101 can feed the second antenna 103 to transmit the signal through the link L22 and receive the signal through the link L24.

[0118] In the circuit four, the communication quality of the electronic device can be further improved by amplifying the signal sent by the electronic device and the signal received by the electronic device through the PA in the circuit four.

[0124] The link L27 is formed by the RF chip 101 , the first LNA 203 , the first duplexer 202 and the first antenna 102 .

[0125] The link L28 is formed by the RF chip 101 , the second LNA 206 , the second duplexer 205 , the second phase shifter 105 and the second antenna 103 .

[0126] When the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can transmit signals through the link L25 and the link L26 at the same time, and can receive signals through the link L27 and the link L28 at the same time. When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the RF chip 101 can feed the first antenna 102 to transmit signals through the link L25 and receive signals through the link L27; or, the RF chip 101 can feed the second antenna 103 to transmit signals through the link L26 and receive signals through the link L28. The specific implementation principles and technical effects of transmitting and receiving signals in Circuit Five are similar to the specific implementation principles and technical effects of transmitting and receiving signals in Circuit Four, and will not be repeated here.

[0127] In the circuit five, the communication quality of the electronic device can be further improved by amplifying the signal sent by the electronic device and the signal received by the electronic device through the PA in the circuit five.

[0131] The link L26 is formed by the RF chip 101 , the second PA 204 , the second duplexer 205 , the second phase shifter 105 and the second antenna 103 .

[0132] like Figure 2 As shown, the circuit six may also include the following two RF receiving links:

[0133] The link L23 is formed by the RF chip 101 , the first LNA 203 , the first duplexer 202 , the first phase shifter 104 and the first antenna 102 .

[0134] The link L28 is formed by the RF chip 101 , the second LNA 206 , the second duplexer 205 , the second phase shifter 105 and the second antenna 103 .

[0135] When the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can transmit signals through the link L21 and the link L26 at the same time. The specific implementation principle and technical effect are as follows: Figure 1 The specific implementation principle and technical effect of the electronic device transmitting a signal when the first antenna 102 and the second antenna 103 are fed simultaneously as shown in the circuit three of the embodiment are similar and will not be repeated here. It should be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 simultaneously, the signal can be received through the link L23 and the link L28 at the same time.

[0136] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the RF chip 101 can feed the first antenna 102 to transmit signals through the link L21 and receive signals through the link L23. For its specific implementation principle and technical effects, please refer to the corresponding specific implementation principle and technical effects in Circuit 4. Alternatively, when the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the RF chip 101 can feed the second antenna 103 to transmit signals through the link L26 and receive signals through the link L28. For its specific implementation principle and technical effects, please refer to the corresponding specific implementation principle and technical effects in Circuit 5, which will not be repeated here.

[0137] In circuit six, the communication quality of the electronic device can be further improved by amplifying the signal sent by the electronic device and the signal received by the electronic device through the PA in circuit six.

[0138] In the case where the duplex communication mode between the electronic device and the base station is the FDD mode, Figure 3 Another circuit diagram of an electronic device provided by an embodiment of the present application is shown.

[0139] like Figure 3 As shown, in Figure 1 Based on the embodiment, the electronic device may further include a third PA 301 , a third LNA 302 , a fourth LNA 303 , a power divider 304 , a third duplexer 305 and a fourth duplexer 306 .

[0140] The input end of the third PA 301 is connected to the RF chip 101. The output end of the third PA 301 is connected to the input end of the power divider 304. One output end of the power divider 304 is connected to the first antenna 102. The other output end of the power divider 304 is connected to the second antenna 103.

[0141] The third duplexer 305 is connected between an output end of the power divider 304 and the first antenna 102. The third duplexer 305 is also connected between the first antenna 102 and an input end of the third LNA 302. The output end of the third LNA 302 is connected to the RF chip 101.

[0142] The fourth duplexer 306 is connected between the other output end of the power divider 304 and the second antenna 103. The fourth duplexer 306 is also connected between the second antenna 103 and the input end of the fourth LNA 303. The output end of the fourth LNA 303 is connected to the RF chip 101.

[0143] The power divider 304 can distribute the power of the signal output by the third PA 301, so that the sum of the transmission power of the first antenna 102 and the transmission power of the second antenna 103 is equal to the power of the signal output by the third PA 301, and can also make the phases of the signals output by the two output ends of the power divider 304 consistent, which can reduce the probability of phase shift before the signal to be transmitted is transmitted to the phase shift unit, thereby further improving the communication quality of the electronic device. The power of the signal output by the third PA 301 can be equal to the transmission power obtained by the electronic device from the base station.

[0144] Exemplarily, through the power distribution of the power divider 304, the transmission power of the first antenna 102 can be the same as the transmission power of the second antenna 103, and the sum of the transmission power of the first antenna 102 and the transmission power of the second antenna 103 is equal to the power of the signal output by the third PA301.

[0145] For example, Figure 3 The circuit shown may include the following RF transmission chain and RF reception chain.

[0146] RF transmission link:

[0147] The link L31 is formed by the RF chip 101 , the third PA 301 , the power divider 304 , the third duplexer 305 and the first antenna 102 .

[0148] The link L32 is formed by the RF chip 101 , the third PA 301 , the power divider 304 , the fourth duplexer 306 and the second antenna 103 .

[0149] RF receiving link:

[0150] The link L33 is formed by the RF chip 101 , the third LNA 302 , the third duplexer 305 and the first antenna 102 .

[0151] The link L34 is formed by the RF chip 101 , the fourth LNA 303 , the fourth duplexer 306 and the second antenna 103 .

[0152] Since the electronic device may include the first phase shift unit 104 and / or the second phase shift unit 105. Therefore, in the embodiment of the present application, the first phase shift unit 104 may be deployed in the following manner: the first phase shift unit 104 is connected between the third duplexer 305 and the first antenna 102, such as Figure 3 Alternatively, the first phase shift unit 104 is connected between the third duplexer 305 and the one output end of the power divider 304, as shown in FIG. Figure 7 The deployment mode of the first phase shifting unit 104 is shown. For ease of understanding, Figure 7 This will be described later.

[0153] The second phase shift unit 105 may be deployed in a manner as follows: the second phase shift unit 105 is connected between the fourth duplexer 306 and the second antenna 103, such as Figure 3 Alternatively, the second phase shifting unit 105 is connected between the fourth duplexer 306 and the other output end of the power divider 304, as shown in FIG. Figure 7 The deployment manner of the second phase shifting unit 105 is shown.

[0154] In the embodiment of the present application, when the electronic device includes the first phase shift unit 104 but does not include the second phase shift unit 105, Figure 3 Among the links L31 , L32 , L33 and L34 included in the circuit, the link L31 also includes a first phase shifting unit 104 .

[0155] In this way, when the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can transmit signals through the link L31 and the link L32 at the same time, and the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power. The specific implementation principle and technical effects can be seen in Figure 2 The specific implementation principle and technical effect of the circuit 4 in the embodiment in which the first antenna 102 and the second antenna 103 are fed simultaneously are not repeated here. It should be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 simultaneously, the electronic device can receive signals through the link L33 and the link L34 at the same time.

[0156] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting a signal through one antenna is also small due to the small transmission power. The RF chip 101 can feed the first antenna 102 to transmit a signal through the link L31 and receive a signal through the link L33; or the RF chip 101 can feed the second antenna 103 to transmit a signal through the link L32 and receive a signal through the link L34.

[0157] In the case where the electronic device includes the second phase shift unit 105 but does not include the first phase shift unit 104, Figure 3 Among the links L31 , L32 , L33 and L34 included in the circuit, the link L32 also includes a second phase shifting unit 105 .

[0158] In this way, when the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can transmit signals through the link L31 and the link L32 at the same time, and the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power. The specific implementation principle and technical effect are similar to Figure 2 The specific implementation principle and technical effect of the electronic device transmitting a signal when the first antenna 102 and the second antenna 103 are fed simultaneously in the circuit five of the embodiment are similar and will not be repeated here. It should be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 simultaneously, the electronic device can receive signals through the link L33 and the link L34 at the same time.

[0159] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting a signal through one antenna is also small due to the small transmission power. The RF chip 101 can feed the first antenna 102 to transmit a signal through the link L31 and receive a signal through the link L33; or the RF chip 101 can feed the second antenna 103 to transmit a signal through the link L32 and receive a signal through the link L34.

[0160] In the case where the electronic device includes the first phase shift unit 104 and the second phase shift unit 105, Figure 3 Among the links L31 , L32 , L33 and L34 included in the circuit, the link L31 further includes a first phase shift unit 104 , and the link L32 further includes a second phase shift unit 105 .

[0161] In this way, when the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can transmit signals through the link L31 and the link L32 at the same time, and the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power. The specific implementation principle and technical effect are similar to Figure 2 The specific implementation principle and technical effect of the electronic device transmitting a signal when the first antenna 102 and the second antenna 103 are fed simultaneously in the circuit 6 of the embodiment are similar and will not be repeated here. It should be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 simultaneously, the electronic device can receive signals through the link L33 and the link L34 at the same time.

[0162] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting a signal through one antenna is also small due to the small transmission power. The RF chip 101 can feed the first antenna 102 to transmit a signal through the link L31 and receive a signal through the link L33; or the RF chip 101 can feed the second antenna 103 to transmit a signal through the link L32 and receive a signal through the link L34.

[0163] In the case where the duplex communication mode between the electronic device and the base station is the FDD mode, Figure 4 Another circuit diagram of an electronic device provided by an embodiment of the present application is shown.

[0164] like Figure 4 As shown, in Figure 3 Based on the embodiment, the electronic device further includes a fifth duplexer 403 , a first switch 405 , a second switch 402 , a third switch 404 and a fourth switch 401 .

[0165] The first switch 405 is connected between the RF chip 101 and the first antenna 102 . The first switch 405 is also connected between the RF chip 101 and the second antenna 103 .

[0166] The second switch 402 is connected to the output end of the third PA 301 , the input end of the power divider 304 , and the fifth duplexer 403 , respectively.

[0167] The third switch 404 is connected to the fifth duplexer 403 , the third duplexer 305 , and the first switch 405 , respectively.

[0168] The fourth switch 401 is connected to the input end of the third LNA 302 , the third duplexer 305 , and the fifth duplexer 403 , respectively.

[0169] When the transmission power obtained by the electronic device from the base station is greater than a preset value, the RF chip 101 can control the first switch 405, the second switch 402, the third switch 404 and the fourth switch 401 so that the following links are all connected:

[0170] The link L41 is formed by the RF chip 101 , the third PA 301 , the power divider 304 , the third duplexer 305 and the first antenna 102 .

[0171] The link L42 is formed by the RF chip 101 , the third PA 301 , the power divider 304 , the fourth duplexer 306 and the second antenna 103 .

[0172] The link L43 is formed by the RF chip 101 , the third LNA 302 , the third duplexer 305 and the first antenna 102 .

[0173] The link L44 is formed by the RF chip 101 , the fourth LNA 303 , the fourth duplexer 306 and the second antenna 103 .

[0174] For example, Figure 4 As shown, when the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can control the terminals A51 and A52 of the first switch 405 to be turned on, the terminals A53 and A54 of the first switch 405 to be turned on, the terminals A21 and A23 of the second switch 402 to be turned on, the terminals A41 and A43 of the third switch 404 to be turned on, and the terminals A11 and A12 of the fourth switch 401 to be turned on, so that the links L41, L42, L43 and L44 are all passages. The RF circuit 101 feeds the first antenna 102 and the second antenna 103 at the same time, so as to transmit signals through the links L41 and L42 at the same time, and receive signals through the links L43 and L44.

[0175] Since the electronic device may include the first phase shift unit 104 and / or the second phase shift unit 105. Therefore, in the embodiment of the present application, the deployment method of the first phase shift unit 104 and the second phase shift unit 105 can refer to Figure 3 Deployment of the first phase shift unit 104 and the second phase shift unit 105 in the embodiment: The first phase shift unit 104 may be connected between the third duplexer 305 and the third switch 404. The second phase shift unit 105 may be connected between the fourth duplexer 306 and the first switch 405.

[0176] When the electronic device includes the first phase shift unit 104 or the second phase shift unit 105, the specific implementation principle and technical effect of the electronic device transmitting and receiving signals when the first antenna 102 and the second antenna 103 are fed simultaneously in the embodiment of the present application are the same as Figure 3In the embodiment, when the electronic device includes the first phase shift unit 104 or the second phase shift unit 105, the specific implementation principle and technical effect of the electronic device transmitting and receiving signals when the first antenna 102 and the second antenna 103 are fed at the same time are similar and will not be repeated here.

[0177] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the RF chip 101 can control the first switch 405, the second switch 402, the third switch 404 and the fourth switch 401 so that the following links are all connected:

[0178] A link L45 is formed by the RF chip 101 , the third PA 301 , the fifth duplexer 403 , and the first antenna 102 or the second antenna 103 .

[0179] The link L46 is formed by the RF chip 101 , the third LNA 302 , the fifth duplexer 403 , and the first antenna 102 or the second antenna 103 .

[0180] For example, Figure 4 As shown, when the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the RF chip 101 can control the first switch 405 to conduct with the endpoint A51 and the endpoint A52 or the first switch 405 to conduct with the endpoint A51 and the endpoint A54, the second switch 402 to conduct with the endpoint A21 and the endpoint A22, the third switch 404 to conduct with the endpoint A41 and the endpoint A42, and the fourth switch 401 to conduct with the endpoint A11 and the endpoint A13, so that the link L45 and the link L46 are both connected. The RF circuit 101 feeds the first antenna 102 or the second antenna 103 to transmit signals through the link L45 and receive signals through the link L46.

[0181] Optionally, the first phase shifting unit 104 may be a phase shifter. Alternatively, the first phase shifting unit 104 may include an inductor and a capacitor, and the first phase shifting unit 104 may be an LC network constructed by the inductor and the capacitor.

[0182] The second phase shifting unit 105 is a phase shifter. Alternatively, the second phase shifting unit 105 may include an inductor and a capacitor, and the second phase shifting unit 105 may be an LC network constructed by the inductor and the capacitor.

[0183] like Figure 4As shown, taking the first phase shift unit 104 connected between the third duplexer 305 and the third switch 404 as an example, the first phase shift unit 104 can be an LC network constructed by an inductor L1, a capacitor C1 and a capacitor C2. Wherein, the inductor L1 is connected between the third duplexer 305 and the third switch 404, one end of the capacitor C1 is connected to one end of the inductor L1, the other end of the capacitor C1 is grounded, one end of the capacitor C2 is connected to the other end of the inductor L1, and the other end of the capacitor C2 is grounded.

[0184] Taking the second phase shift unit 105 connected between the fourth duplexer 306 and the sixth switch 502 as an example, the second phase shift unit 105 can be an LC network constructed by an inductor L2, an inductor L3 and a capacitor C3. The capacitor C3 is connected between the fourth duplexer 306 and the sixth switch 502, one end of the inductor L2 is connected to one end of the capacitor C3, the other end of the inductor L2 is grounded, one end of the inductor L3 is connected to the other end of the capacitor C3, and the other end of the inductor L3 is grounded.

[0185] Optionally, in the embodiment of the present application, the third switch 404 and the first switch 405 may be two independent switches. The third switch 404 and the first switch 405 may also be two parts of a switch, so that the power consumption of the electronic device can be reduced.

[0186] In the case where the duplex communication mode between the electronic device and the base station is the FDD mode, Figure 5 Another circuit diagram of an electronic device provided by an embodiment of the present application is shown.

[0187] like Figure 5 As shown, in Figure 4 Based on the embodiment, the electronic device may further include a fifth switch 501 and a sixth switch 502 .

[0188] The fifth switch 501 is connected to the input end of the fourth LNA 303 , the fourth duplexer 306 , and the sixth switch 502 , respectively.

[0189] The sixth switch 502 is also connected to the first switch 405 and the fourth duplexer 306. When the electronic device includes the second phase shifter 105, the second phase shifter 105 can be connected between the fourth duplexer 306 and the sixth switch 502, and the second phase shifter 105 can also be connected between the sixth switch 502 and the first switch 405.

[0190] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the radio frequency chip 101 may further control the fifth switch 501 and the sixth switch 502 so that the following links are connected:

[0191] The link L51 is formed by the RF chip 101 , the fourth LNA 303 and the first antenna 102 or the second antenna 103 .

[0192] For example, Figure 5 As shown, when the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the RF chip 101 can also control the endpoints B11 and B13 of the fifth switch 501 to be turned on, and the endpoints B21 and B23 of the sixth switch 502 to be turned on, so that the link L51 is a passage. The RF circuit 101 feeds the first antenna 102 or the second antenna 103 to transmit a signal through the link L45, and simultaneously receives a signal through the link L46 and the link L51, so that more links are made for receiving signals, which can further improve the communication quality of the electronic device.

[0193] Alternatively, if Figure 5 As shown, the electronic device further includes: a first filter 503. The first filter 503 is connected between the fifth switch 501 and the sixth switch 502. The first filter 503 can filter the signal passing through the link L51, thereby further improving the communication quality of the electronic device.

[0194] Optionally, in the embodiment of the present application, the first switch 405 and the sixth switch 502 may be two independent switches. The first switch 405 and the sixth switch 502 may also be two parts of a switch, so that the power consumption of the electronic device can be reduced. It should be understood that the third switch 404, the first switch 405 and the sixth switch 502 may also be three parts of a switch, so that the power consumption of the electronic device can be reduced.

[0195] In the case where the duplex communication mode between the electronic device and the base station is the FDD mode, Figure 6 Another circuit diagram of an electronic device provided by an embodiment of the present application is shown.

[0197] exist Figure 6In the illustrated embodiment, the signal received by the electronic device will not be phase shifted by the phase shift unit, so the electronic device does not need to perform special processing for the phase shift of the received signal, which can reduce the processing time and power consumption of the electronic device for the received signal.

[0200] exist Figure 7 In the illustrated embodiment, the signal received by the electronic device will not be phase shifted by the phase shift unit, so the electronic device does not need to perform special processing for the phase shift of the received signal, which can reduce the processing time and power consumption of the electronic device for the received signal.

[0201] In the case where the duplex communication mode between the electronic device and the base station is the FDD mode, Figure 8 Another circuit diagram of an electronic device provided by an embodiment of the present application is shown.

[0202] Figure 8 and Figure 4 The difference is: Figure 4 In the embodiment, the first phase shifting unit 104 is connected between the third duplexer 305 and the first antenna 102, and the second phase shifting unit 105 is connected between the fourth duplexer 306 and the second antenna 103. Figure 8 In the embodiment, the first phase shifting unit 104 is connected between the third duplexer 305 and the power divider 304 , and the second phase shifting unit 105 is connected between the fourth duplexer 306 and the power divider 304 .

[0203] exist Figure 8 In the illustrated embodiment, the signal received by the electronic device will not be phase shifted by the phase shift unit, so the electronic device does not need to perform special processing for the phase shift of the received signal, which can reduce the processing time and power consumption of the electronic device for the received signal.

[0204] In the case where the duplex communication mode between the electronic device and the base station is the TDD mode, Fig. 9Another circuit diagram of an electronic device provided by an embodiment of the present application is shown.

[0205] like Fig. 9 As shown, in Figure 1 Based on the embodiment, the electronic device may further include a third PA 301 , a third LNA 302 , a fourth LNA 303 , a power divider 304 , a second filter 901 , a third filter 902 , a fourth filter 903 and a fifth filter 904 .

[0206] The input end of the third PA 301 is connected to the RF chip 101 , the output end of the third PA 301 is connected to the input end of the power divider 304 , one output end of the power divider 304 is connected to the first antenna 102 , and the other output end of the power divider 304 is connected to the second antenna 103 .

[0207] An input end of the third LNA 302 is connected to the first antenna 102 , and an output end of the third LNA 302 is connected to the RF chip 101 .

[0208] An input end of the fourth LNA 3003 is connected to the second antenna 103 , and an output end of the fourth LNA 3003 is connected to the RF chip 101 .

[0209] The second filter 901 is connected between an output terminal of the power divider 304 and the first antenna 102 .

[0210] The third filter 902 is connected between the other output terminal of the power divider 304 and the second antenna 103 .

[0211] The fourth filter 903 is connected between the input terminal of the third LNA 302 and the first antenna 102 .

[0212] The fifth filter 904 is connected between the input terminal of the fourth LNA 303 and the second antenna 103 .

[0213] like Fig. 9 The circuit shown may include the following radio frequency transmission link and radio frequency receiving link.

[0214] RF transmission link:

[0215] The link L91 is formed by the RF chip 101 , the third PA 301 , the power divider 304 , the second filter 901 and the first antenna 102 .

[0216] The link L92 is formed by the RF chip 101 , the third PA 301 , the power divider 304 , the third filter 902 and the second antenna 103 .

[0217] RF receiving link:

[0218] The link L93 is formed by the RF chip 101 , the third LNA 302 , the fourth filter 903 and the first antenna 102 .

[0219] The link L94 is formed by the RF chip 101 , the fourth LNA 303 , the fifth filter 904 and the second antenna 103 .

[0220] like Figure 1 As shown in the embodiment, the electronic device may include a first phase shift unit 104 and / or a second phase shift unit 105. In the embodiment of the present application, the first phase shift unit 104 may be deployed in the following manner: the first phase shift unit 104 is connected between the second filter 901 and the first antenna 102, such as Fig. 9 Alternatively, the first phase shift unit 104 is connected between the second filter 901 and the one output end of the power divider 304 .

[0221] The second phase shifting unit 105 may be deployed in a manner as follows: the second phase shifting unit 105 is connected between the third filter 902 and the second antenna 103, such as Fig. 9 Alternatively, the second phase shifting unit 105 is connected between the third filter 902 and the other output end of the power divider 304 .

[0222] In the embodiment of the present application, when the electronic device includes the first phase shift unit 104 but does not include the second phase shift unit 105, Fig. 9 Among the links L91 , L92 , L93 and L94 included in the circuit, the link L91 also includes a first phase shifting unit 104 .

[0223] In this way, when the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can transmit signals through the link L91 and the link L92 at the same time, and the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power. The specific implementation principle and technical effects can be seen in Figure 3 In the embodiment, when the electronic device includes the first phase shift unit 104 but does not include the second phase shift unit 105, the specific implementation principle and technical effect of the electronic device transmitting the signal through the link L31 and the link L32 at the same time will not be repeated here. It should be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 at the same time, the electronic device can receive signals through the link L93 and the link L94 at the same time.

[0224] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting the signal through one antenna is also small due to the small transmission power. The RF chip 101 can feed the first antenna 102 to transmit the signal through the link L91 and simultaneously receive the signal through the link L93 and the link L94; or, the RF chip 101 can feed the second antenna 103 to transmit the signal through the link L92 and simultaneously receive the signal through the link L93 and the link L94.

[0225] In the case where the electronic device includes the second phase shift unit 105 but does not include the first phase shift unit 104, Fig. 9 Among the links L91 , L92 , L93 and L94 included in the circuit, the link L92 also includes a second phase shifting unit 105 .

[0226] For the situation where the transmission power obtained by the electronic device from the base station is greater than the preset value, when the electronic device includes the second phase shift unit 105 but does not include the first phase shift unit 104, the specific implementation principle and technical effect of the electronic device transmitting and receiving signals are similar to the specific implementation principle and technical effect of the electronic device transmitting and receiving signals when the electronic device includes the first phase shift unit 104 but does not include the second phase shift unit 105, and will not be repeated here.

[0227] For the case where the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, when the electronic device includes the second phase shift unit 105 but does not include the first phase shift unit 104, the specific implementation principle and technical effect of the electronic device transmitting and receiving signals are similar to the specific implementation principle and technical effect of the electronic device transmitting and receiving signals when the electronic device includes the first phase shift unit 104 but does not include the second phase shift unit 105, and will not be repeated here.

[0228] In the case where the electronic device includes the first phase shift unit 104 and the second phase shift unit 105, Fig. 9 Among the links L91 , L92 , L93 and L94 included in the circuit, the link L91 further includes a first phase shift unit 104 , and the link L92 further includes a second phase shift unit 105 .

[0229] In this way, when the transmission power obtained by the electronic device from the base station is greater than the preset value, the RF chip 101 can feed the first antenna 102 and the second antenna 103 at the same time, and the electronic device can transmit signals through the link L91 and the link L92 at the same time, and the transmission power of the electronic device is greater than or equal to the sum of the first transmission power and the second transmission power. The specific implementation principle and technical effect are similar to Figure 2The specific implementation principle and technical effect of the electronic device transmitting a signal when the first antenna 102 and the second antenna 103 are fed simultaneously in the circuit 6 of the embodiment are similar and will not be repeated here. It should be understood that when the RF chip 101 feeds the first antenna 102 and the second antenna 103 simultaneously, the electronic device can receive signals through the link L93 and the link L94 at the same time.

[0230] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the SAR value when transmitting the signal through one antenna is also small due to the small transmission power. The RF chip 101 can feed the first antenna 102 to transmit the signal through the link L91 and simultaneously receive the signal through the link L93 and the link L94; or, the RF chip 101 can feed the second antenna 103 to transmit the signal through the link L92 and simultaneously receive the signal through the link L93 and the link L94.

[0231] Alternatively, if Fig. 9 As shown, the electronic device may further include: a sixth filter 905 , a seventh switch 906 and an eighth switch 907 .

[0232] The seventh switch 906 is connected to the first antenna 102 , the second antenna 103 , the second filter 901 , the third filter 902 , the fourth filter 903 , the fifth filter 904 , and the sixth filter 905 , respectively.

[0233] The eighth switch 907 is connected to the output end of the third PA 301 , the input end of the power divider 304 , and the sixth filter 905 , respectively.

[0234] When the transmission power obtained by the electronic device from the base station is greater than a preset value, the radio frequency chip 101 can control the seventh switch 906 and the eighth switch 907 so that the following links are all connected:

[0235] The link L91 is formed by the RF chip 101 , the third PA 301 , the second filter 901 and the first antenna 102 .

[0236] The link L92 is formed by the RF chip 101 , the third PA 301 , the third filter 902 and the second antenna 103 .

[0237] The link L93 is formed by the RF chip 101 , the third LNA 302 , the fourth filter 903 and the first antenna 102 .

[0238] The link L94 is formed by the RF chip 101 , the fourth LNA 303 , the fifth filter 904 and the second antenna 103 .

[0239] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the radio frequency chip 101 may also control the seventh switch 906 and the eighth switch 907 so that the following links are all connected:

[0240] A link L95 is formed by the RF chip 101, the third PA 301, the sixth filter 905, and the first antenna or the second antenna.

[0241] The link L96 is formed by the RF chip 101 , the third LNA 302 , the fourth filter 903 and the first antenna 102 or the second antenna 103 .

[0242] The link L97 is formed by the RF chip 101 , the fourth LNA 303 , the fifth filter 904 , and the first antenna 102 or the second antenna 103 .

[0243] For example, Fig. 9 As shown, when the transmission power obtained by the electronic device from the base station is greater than a preset value, the RF chip 101 can control the endpoint D61 and the endpoint D65 of the seventh switch 906 to be turned on, the endpoint D62 and the endpoint D66 of the seventh switch 906 to be turned on, the endpoint D61 and the endpoint D63 of the seventh switch 906 to be turned on, the endpoint D62 and the endpoint D67 of the seventh switch 906 to be turned on, and the endpoint D71 and the endpoint D73 of the eighth switch 907 to be turned on, so that the link L91, the link L92, the link L93 and the link L94 are all passages, so as to transmit signals through the link L91 and the link L92, and receive signals through the link L93 and the link L94.

[0244] For example, when the transmission power obtained by the electronic device from the base station is greater than a preset value, when the electronic device transmits a signal, the RF chip 101 can control the terminal D61 and the terminal D65 of the seventh switch 906 to be turned on, the terminal D62 and the terminal D66 of the seventh switch 906 to be turned on, and the terminal D71 and the terminal D73 of the eighth switch 907 to be turned on. When the electronic device receives a signal, the RF chip 101 can control the terminal D61 and the terminal D63 of the seventh switch 906 to be turned on, and the terminal D62 and the terminal D67 of the seventh switch 906 to be turned on.

[0245] When the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, the RF chip 101 can control the endpoint D64 of the seventh switch 906 to be turned on with the endpoint D61, the endpoint D61 of the seventh switch 906 to be turned on with the endpoint D63, the endpoint D62 of the seventh switch 906 to be turned on with the endpoint D67, and the endpoint D71 of the eighth switch 907 to be turned on with the endpoint D72. Alternatively, the RF chip 101 can control the endpoint D64 of the seventh switch 906 to be turned on with the endpoint D62, the endpoint D61 of the seventh switch 906 to be turned on with the endpoint D63, the endpoint D62 of the seventh switch 906 to be turned on with the endpoint D67, and the endpoint D71 of the eighth switch 907 to be turned on with the endpoint D72. In this way, the link L95, the link L96, and the link L97 can all be passages, so that signals are transmitted through the link L95, and signals are received through the link L96 and the link L97.

[0246] For example, when the transmission power obtained by the electronic device from the base station is less than or equal to the preset value, when the electronic device transmits a signal, the RF chip 101 controls the terminal D64 of the seventh switch 906 to be turned on with the terminal D61, and the terminal D71 of the eighth switch 907 to be turned on with the terminal D72. Alternatively, the RF chip 101 controls the terminal D64 of the seventh switch 906 to be turned on with the terminal D62, and the terminal D71 of the eighth switch 907 to be turned on with the terminal D72. When the electronic device receives a signal, the RF chip 101 controls the terminal D61 of the seventh switch 906 to be turned on with the terminal D63, and the terminal D62 of the seventh switch 906 to be turned on with the terminal D67.

[0247] Optionally, in a possible implementation, the electronic device may further include a first PA 201, a first LNA 203, a second PA 204, a second LNA 206, a second filter 901 and a third filter 902. In the embodiment of the present application, the second filter 901 is deployed in the same manner as in the embodiment of the present invention. Figure 2 The first duplexer 202 is deployed in the same manner as in the embodiment. Figure 2 The second duplexer 205 is deployed in the same manner as in the embodiment. The deployment manner of the first PA 201, the first LNA 203, the second PA 204 and the second LNA 206 in the embodiment of the present application can be referred to. Figure 2 In the embodiment, the first PA 201, the first LNA 203, the second PA 204 and the second LNA 206 are deployed in the same manner, which will not be described in detail here.

[0248] In the embodiment of the present application, since the electronic device may include the first phase shift unit 104 and / or the second phase shift unit 105, in the embodiment of the present application, the first phase shift unit 104 may be deployed in such a manner that: the first phase shift unit 104 is connected between the second filter 901 and the first antenna 102. Alternatively, the first phase shift unit 104 is connected between the second filter 901 and the output end of the first PA 201.

[0249] The second phase shift unit 105 may be deployed in the following manner: the second phase shift unit 105 is connected between the third filter 902 and the second antenna 103 . Alternatively, the second phase shift unit 105 is connected between the output end of the third filter 902 and the second PA 204 .
