Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a radio frequency transceiver device and electronic device. Background Technology

[0002] Radio frequency (RF) transceivers can be used to transmit and / or receive electromagnetic wave signals to enable communication with other devices (such as base stations). In some scenarios, RF transceivers in related technologies need to distinguish between board-level status (also known as conducted status or conducted test status) and overall system status. However, RF transceivers in related technologies are prone to misjudgment when distinguishing between board-level status (also known as conducted status or conducted test status) and overall system status. Summary of the Invention

[0003] In a first aspect, one embodiment of this application provides a radio frequency transceiver device, the radio frequency transceiver device comprising:

[0004] A transceiver used to transmit the first radio frequency signal;

[0005] A first radio frequency front-end module is electrically connected to the transceiver and is used to amplify the power of the first radio frequency signal.

[0006] A first power coupler is electrically connected to the first RF front-end module and the transceiver;

[0007] The first test socket is electrically connected to the first power coupler;

[0008] A first auxiliary coupler is electrically connected to the first test socket and the transceiver; and

[0009] A first radiator is electrically connected to the first auxiliary coupler, and the first radiator is excited by the first radio frequency signal to generate an electromagnetic wave signal in the first frequency band.

[0010] The transceiver is used to determine whether the radio frequency transceiver is in a conducted test state or a complete unit state based on the first power signal fed back by the first power coupler and the first auxiliary power signal fed back by the first auxiliary coupler.

[0011] If the RF transceiver is in a conducted test state, the first RF signal is output to the tester via the first test socket and cannot be transmitted to the first auxiliary coupler; if the RF transceiver is in a complete state, the first RF signal is transmitted to the first radiator via the first test socket and the first auxiliary coupler.

[0012] Secondly, one embodiment of this application provides an electronic device, which includes the radio frequency transceiver device as described in the first aspect.

[0013] In summary, the RF front-end transceiver device provided in this application includes not only a first power coupler located between the first RF front-end module and the first test socket, but also a first auxiliary coupler located between the first test socket and the first radiator. If the RF transceiver device is in a conducted test state, the first RF signal is output to the tester via the first test socket and cannot be output to the first auxiliary coupler. If the RF transceiver device is in a complete unit state, the first RF signal can be transmitted to the first auxiliary coupler via the first test socket. Therefore, the transceiver can determine whether the RF transceiver device is in a conducted test state or a complete unit state based on the first power signal fed back by the first power coupler and the first auxiliary power signal fed back by the first auxiliary coupler. This improves the accuracy, reliability, and consistency of determining whether the RF transceiver device is in a conducted test state or a complete unit state. Attached Figure Description

[0027] Before introducing the radio frequency transceiver device 10 provided in the embodiments of this application, a detailed description of the radio frequency transceiver device 10 in the related art will be given. The radio frequency transceiver device 10 in the related art is the radio frequency transceiver device 10 prior to the improvements in the embodiments of this application. The radio frequency transceiver device 10 in the related art should not be construed as the radio frequency transceiver device 10 in the prior art. In other words, the radio frequency transceiver device 10 in the related art described herein is not the radio frequency transceiver device 10 in the prior art.

[0028] The radio frequency transceiver 10 can be used to transmit and / or receive electromagnetic wave signals to achieve communication with other devices (such as base stations). In some scenarios, the radio frequency transceiver 10 in the related art needs to distinguish between board-level status (also known as conducted status, or conducted test status) and overall system status. However, the radio frequency transceiver 10 in the related art cannot effectively distinguish between board-level status and overall system status.

[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of a radio frequency transceiver device provided in a first embodiment of the related art. The radio frequency transceiver device 10 in the related art includes a transceiver 100, a first radio frequency front-end module 110, a first power coupler 120, a first test socket 130, and a first radiator 150. The transceiver 100 is used to transmit a first radio frequency signal. The radio frequency transceiver device 10 is electrically connected to the transceiver 100 and is used to amplify the power of the first radio frequency signal. The first power coupler 120 is electrically connected to the first radio frequency front-end module 110 and the transceiver 100. The first test socket 130 is electrically connected to the first power coupler 120. The first radiator 150 is electrically connected to the first test socket 130. The first radiator 150 is excited by the first radio frequency signal to generate an electromagnetic wave signal in a first frequency band.

[0030] In related technologies, the RF transceiver 10 performs power testing using a first power coupler 120 located between the first RF front-end module 110 and the first test socket 130 for both conducted power (also known as conducted test power) in its conducted state (also known as board-level state or conducted test state) and overall coupling power in its complete unit state. The transceiver 100 is used to precisely control the power of the first RF signal. However, in some scenarios, power matching is required when the RF transceiver 10 is in its complete unit state, necessitating a distinction between the board-level and complete unit states over the air. For example, safety factors such as the Specific Absorption Rate (SAR) need to be tested when the RF transceiver 10 is in its complete unit state. Therefore, a distinction between the board-level and complete unit states over the air is required for the RF transceiver 10.

[0031] In related technologies, the RF transceiver 10 distinguishes between a board-level state and a complete device state by using a grounding spring for detection. Specifically, the grounding spring is typically a conductive spring, such as a metal spring. When the electronic device 1 to which the RF transceiver 10 is used is assembled, the metal spring is electrically connected to the conductive battery cover within the electronic device 1. If the RF transceiver 10 is in a board-level state, it is not assembled into the electronic device 1, and the metal spring is not electrically connected to the conductive battery cover. The RF transceiver 10 being used in the electronic device 1 can also be referred to as being in a complete device state; if the RF transceiver 10 is not assembled into the electronic device 1, it is also referred to as being in a board-level state. The conductive battery cover can usually be considered as ground. Therefore, if the RF transceiver 10 is in a complete device state, the metal spring is electrically connected to the battery cover for grounding; if the RF transceiver 10 is in a board-level state, the metal spring is not electrically connected to ground. Therefore, it can be seen that in related technologies, by detecting the grounding spring, it is possible to distinguish whether the radio frequency transceiver 10 is in board-level state or whole-machine state.

[0032] In related technologies, if the radio frequency transceiver 10 is in a complete unit state, the first power signal obtained by the first power coupler 120 is the power in the complete unit state; if the radio frequency transceiver 10 is in a board-level state, the first power signal obtained by the first power coupler 120 is the power in the board-level state.

[0033] However, in the first embodiment of the related technology, the use of the detection grounding spring to determine whether the RF transceiver 10 is in a board-level state or a complete unit state has certain reliability and consistency issues. For example, if the RF transceiver 10 is in a complete unit state, there may be situations where the detection grounding spring and the battery cover do not make contact. If the RF transceiver 10 is in a complete unit state, and the detection grounding spring does not make contact, then the RF transceiver 10, which was originally in a complete unit state, will be judged as being in a board-level state. Therefore, it can be seen that the RF transceiver 10 in the related technology has a certain degree of misjudgment when distinguishing between a board-level state (also known as a conducted test state) and a complete unit state.

[0034] Please see Figure 2 , Figure 2 This is a schematic diagram of a radio frequency transceiver device provided in a second embodiment of the related art. Figure 1 The radio frequency transceiver 10 shown includes one transmit / receive path. Figure 2The illustrated radio frequency transceiver 10 includes three transmit and receive paths. Specifically, the radio frequency transceiver 10 further includes a switching switch 60, a second radio frequency front-end module 210, a second power coupler 220, a second test socket 230, and a second radiator 250; furthermore, the radio frequency transceiver 10 also includes a third radio frequency front-end module 310, a third power coupler 320, a third test socket 330, and a third radiator 350. The transceiver 100 is also used to transmit a second radio frequency signal. The second radio frequency front-end module 210 is electrically connected to the transceiver 100 and is used to amplify the power of the second radio frequency signal. The second power coupler 220 is electrically connected to the second radio frequency front-end module 210 and the transceiver 100. The second test socket 230 is electrically connected to the second power coupler 220. The second radiator 250 is electrically connected to the second test socket 230. The second radiator 250 is excited by the second radio frequency signal to generate an electromagnetic wave signal in a second frequency band. The transceiver 100 is also used to transmit a third radio frequency (RF) signal. The third RF front-end module 310 is electrically connected to the transceiver 100 and is used to amplify the power of the third RF signal. The third power coupler 320 is electrically connected to the third RF front-end module 310 and the transceiver 100. The third test socket 330 is electrically connected to the third power coupler 320. The third radiator 350 is electrically connected to the third test socket 330. The third radiator 350 is excited by the third RF signal to generate an electromagnetic wave signal in a third frequency band. Specifically, in this embodiment, when the first power coupler 120, the second power coupler 220, and the third power coupler 320 are electrically connected to the transceiver 100, they are electrically connected to the transceiver 100 via a switching switch 60.

[0035] exist Figure 2 The RF transceiver 10 provided in the second embodiment of the related technology also uses a detection spring to determine whether the RF transceiver 10 is in a board-level state or a complete system state. However, in the second embodiment of the related technology, there are certain reliability and consistency issues in using the detection grounding spring to determine whether the RF transceiver 10 is in a board-level state or a complete system state. For example, if the RF transceiver 10 is in a complete system state, there may be a situation where the detection grounding spring does not make contact with the battery cover. If the RF transceiver 10 is in a complete system state, and the detection grounding spring does not make contact with the battery cover, then the RF transceiver 10, which was originally in a complete system state, will be judged as being in a board-level state. Therefore, it can be seen that the RF transceiver 10 in the related technology has a certain degree of misjudgment when distinguishing between a board-level state (also known as a conducted test state) and a complete system state.

[0036] Next, the radio frequency transceiver 10 provided in the embodiments of this application will be described in detail. Please refer to... Figure 3 , Figure 3 This is a schematic diagram of a radio frequency transceiver device according to an embodiment of this application. The radio frequency transceiver device 10 includes a transceiver 100, a first radio frequency front-end module 110, a first power coupler 120, a first test socket 130, a first auxiliary coupler 140, and a first radiator 150. The transceiver 100 is used to transmit a first radio frequency signal. The first radio frequency front-end module 110 is electrically connected to the transceiver 100 and is used to amplify the power of the first radio frequency signal. The first power coupler 120 is electrically connected to the first radio frequency front-end module 110 and the transceiver 100. The first test socket 130 is electrically connected to the first power coupler 120. The first auxiliary coupler 140 is electrically connected to the first test socket 130 and the transceiver 100. The first radiator 150 is electrically connected to the first auxiliary coupler 140, and the first radiator 150 is excited by the first radio frequency signal to generate an electromagnetic wave signal in a first frequency band. The transceiver 100 is used to determine whether the RF transceiver 10 is in a conducted test state or a complete unit state based on the first power signal fed back by the first power coupler 120 and the first auxiliary power signal fed back by the first auxiliary coupler 140. If the RF transceiver 10 is in a conducted test state (also called a conducted state or board-level state), the first RF signal is output to the tester via the first test socket 130 and cannot be transmitted to the first auxiliary coupler 140. If the RF transceiver 10 is in a complete unit state, the first RF signal is transmitted to the first radiator 150 via the first test socket 130 and the first auxiliary coupler 140.

[0037] The transceiver 100 is used to transmit a first radio frequency signal, which is used to excite the first radiator 150 to generate an electromagnetic wave signal in a first frequency band. In other embodiments, the first radiator 150 receives the electromagnetic wave signal in the first frequency band and converts it into a radio frequency signal. For ease of naming, the first radiator 150 receives the electromagnetic wave signal in the first frequency band and names the signal obtained by converting it into a first signal. The transceiver 100 is also used to receive the first signal.

[0038] The first RF front-end module 110 is used to amplify the power of the first RF signal. The amplified first RF signal is output to the first power coupler 120. In one embodiment, the first RF front-end module 110 includes a power amplifier (PA). For ease of description, the power amplifier of the first RF front-end module 110 is referred to as the first power amplifier. The first power amplifier is used to amplify the power of the first RF signal.

[0039] If the first radiator 150 receives an electromagnetic wave signal in the first frequency band, it converts the electromagnetic wave signal in the first frequency band into a first signal. The first radio frequency front-end module 110 is also used to amplify the first signal with low noise power. In one embodiment, the first radio frequency front-end module 110 further includes a low noise amplifier, which is referred to as a first low noise amplifier for ease of description. The first low noise amplifier is used to amplify the first signal with low noise power. The first signal after low noise power amplification is transmitted to the transceiver 100.

[0040] The first power coupler 120 is electrically connected to the first RF front-end module 110 and is used to receive the amplified first RF signal output from the first RF front-end module 110. The first power coupler 120 couples the amplified first RF signal output from the first RF front-end module 110 to obtain a first power signal. The first power coupler 120 is electrically connected to the transceiver 100 to output the first power signal to the transceiver 100.

[0041] The first test socket 130 is electrically connected to the first power coupler 120. If testing of the RF transceiver 10 is required, a tester can be electrically connected to the first test socket 130 for testing. If the RF transceiver 10 is in a conducted test state, the first test socket 130 is used to electrically connect to the tester. The first RF signal cannot be conducted to the first auxiliary coupler 140 via the first test socket 130. If the RF transceiver 10 is in a complete unit state, the first RF signal can be conducted to the first auxiliary coupler 140 via the first test socket 130 and then to the first radiator 150.

[0042] The radio frequency transceiver device 10 provided in this application includes a first auxiliary coupler 140, which is located between the first test socket 130 and the first radiator 150. Therefore, the radio frequency transceiver device 10 provided in this application is equivalent to adding a first auxiliary coupler 140 to the radio frequency transceiver device 10 in the related art.

[0043] The first auxiliary coupler 140 is electrically connected to the first test socket 130, coupling the amplified first radio frequency signal output from the first radio frequency front-end module 110 to obtain a first auxiliary power signal. The first auxiliary coupler 140 may also be referred to as the first auxiliary coupler 140. The first auxiliary coupler 140 is electrically connected to the transceiver 100 to output the first auxiliary power signal to the transceiver 100.

[0044] Therefore, as described above, if the RF transceiver 10 is in the conducted test state (also known as the board-level state), the transmission path of the first RF signal emitted by the transceiver 100 is: transceiver 100, first RF front-end module 110, first power coupler 120, first test socket 130, and tester. Thus, if the RF transceiver 10 is in the conducted test state (also known as the board-level state): the first power coupler 120 can couple the first RF signal amplified by the first RF front-end module 110, while the first auxiliary coupler 140 cannot couple to the first RF signal amplified by the first RF front-end module 110. Therefore, if the RF transceiver 10 is in the conducted test state, the difference between the first power signal and the first auxiliary power signal is significant.

[0045] If the RF transceiver 10 is in its complete state, the transmission path of the first RF signal emitted by the transceiver 100 is: transceiver 100, first RF front-end module 110, first power coupler 120, first test socket 130, first auxiliary coupler 140, and first radiator 150. Therefore, if the RF transceiver 10 is in its complete state: the first power coupler 120 can couple the first RF signal amplified by the first RF front-end module 110, and the first auxiliary coupler 140 can couple to the first RF signal amplified by the first RF front-end module 110. Therefore, if the RF transceiver 10 is in its complete state, the first power signal and the first auxiliary power signal are equal or approximately equal.

[0046] The transceiver 100 is electrically connected to the first power coupler 120 to receive the first power signal fed back by the first power coupler 120; and the transceiver 100 is electrically connected to the first auxiliary coupler 140 to receive the first auxiliary power signal fed back by the first auxiliary coupler 140. The transceiver 100 determines whether the RF transceiver device 10 is in a conducted test state or a complete system state based on the first power signal and the first auxiliary power signal. Therefore, the RF transceiver device 10 provided in this embodiment can effectively distinguish between a conducted test state and a complete system state. Thus, the air interface detection mechanism of the RF transceiver device 10 provided in this embodiment is more reliable and has better consistency than related technologies.

[0047] In summary, the RF transceiver 10 provided in this application includes not only a first power coupler 120 located between the first RF front-end module 110 and the first test socket 130, but also a first auxiliary coupler 140 located between the first test socket 130 and the first radiator 150. If the RF transceiver 10 is in a conducted test state, the first RF signal is output to the tester via the first test socket 130 and cannot be output to the first auxiliary coupler 140. If the RF transceiver 10 is in a complete unit state, the first RF signal can be transmitted to the first auxiliary coupler 140 via the first test socket 130. Therefore, the transceiver 100 can determine whether the RF transceiver 10 is in a conducted test state or a complete unit state based on the first power signal fed back by the first power coupler 120 and the first auxiliary power signal fed back by the first auxiliary coupler 140. This improves the accuracy, reliability, and consistency of determining whether the RF transceiver 10 is in a conducted test state or a complete unit state.

[0048] Further, in one embodiment, the ratio of the first power signal A to the first auxiliary power signal A' is a first ratio X1, i.e., X1 = A / A'. If the first ratio X1 satisfies: X1 > 10, the transceiver 100 determines that the RF transceiver device 10 is in a conducted test state. If the first ratio X1 satisfies: 0.5 ≤ X1 ≤ 1.5, the transceiver 100 determines that the RF transceiver device 10 is in a complete unit state.

[0049] As described above, if the RF transceiver 10 is in a conducted test state: the first power coupler 120 can couple the first RF signal amplified by the first RF front-end module 110, while the first auxiliary coupler 140 cannot couple to the first RF signal amplified by the first RF front-end module 110. Therefore, if the RF transceiver 10 is in a conducted test state, the difference between the first power signal and the first auxiliary power signal is large, and the first ratio X1 is much greater than 10. Therefore, if the first ratio X1 satisfies: X1 > 10, the transceiver 100 determines that the RF transceiver 10 is in a conducted test state.

[0050] Furthermore, as described above, if the RF transceiver 10 is in its complete state: the first power coupler 120 can couple the first RF signal amplified by the first RF front-end module 110, and the first auxiliary coupler 140 can couple to the first RF signal amplified by the first RF front-end module 110. Therefore, if the RF transceiver 10 is in its complete state, the first power signal and the first auxiliary power signal are equal or approximately equal. The first ratio X1 is small, equal to or close to 1. Therefore, if the first ratio X1 satisfies: 0.5 ≤ X1 ≤ 1.5, the transceiver 100 determines that the RF transceiver 10 is in its complete state.

[0051] The radio frequency transceiver 10 provided in this application embodiment has a first ratio X1 as the ratio of the first power to the first auxiliary power. The transceiver 100 uses the magnitude of the first ratio X1 to determine whether the radio frequency transceiver 10 is in a conducted test state or a complete unit state. This improves the accuracy, reliability, and consistency of determining whether the radio frequency transceiver 10 is in a conducted test state or a complete unit state.

[0052] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of a radio frequency transceiver device provided in one embodiment of this application. The radio frequency transceiver device 10 includes a circuit board 40. The transceiver 100, the first radio frequency front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all located on the circuit board 40.

[0053] The circuit board 40 can be, but is not limited to, a printed circuit board (PCBA). In this embodiment, the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all located on the circuit board 40. For example, the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all surface-mounted on the circuit board 40. The transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 can be electrically connected, but is not limited to, through wiring connections on the conductive layer of the circuit board 40.

[0054] The transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all located on the circuit board 40. Therefore, the electrical connection between the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 is relatively reliable, thereby improving the accuracy, reliability, and consistency of determining whether the RF transceiver device 10 is in a conducted test state or a complete unit state.

[0055] Please see Figure 5 , Figure 5 This is a schematic diagram of a radio frequency transceiver device provided in another embodiment of this application. The radio frequency transceiver device 10 further includes a switching switch 60. The switching switch 60 has a common terminal 600, a first connection terminal 610, and a second connection terminal 620. The common terminal 600 is electrically connected to the transceiver 100, the first connection terminal 610 is electrically connected to the first power coupler 120, and the second connection terminal 620 is electrically connected to the first auxiliary coupler 140. If the common terminal 600 is electrically connected to the first connection terminal 610, the transceiver 100 is electrically connected to the first power coupler 120, and the transceiver 100 is used to receive the first power signal. If the common terminal 600 is electrically connected to the second connection terminal 620, the transceiver 100 is electrically connected to the first auxiliary coupler 140, and the transceiver 100 is used to receive the first auxiliary power signal.

[0056] In one embodiment, the common terminal 600 of the switch 60 can be electrically connected to either the first connection terminal 610 or the second connection terminal 620. If the common terminal 600 of the switch 60 is electrically connected to the first connection terminal 610, the common terminal 600 is disconnected from the second connection terminal 620. If the common terminal 600 of the switch 60 is electrically connected to the second connection terminal 620, the common terminal 600 is disconnected from the first connection terminal 610.

[0057] The switching switch 60 can be electrically connected to either the first connection terminal 610 or the second connection terminal 620, and is also referred to as a single-pole double-throw switch. That is, the switching switch 60 is a single-pole multi-throw switch (SPnT), or simply an SPnT switch, where n=2. If the common terminal 600 is electrically connected to the first connection terminal 610, the first power coupler 120 is electrically connected to the transceiver 100, and the transceiver 100 can receive the first power signal from the first power coupler 120. If the common terminal 600 is electrically connected to the second connection terminal 620, the first auxiliary coupler 140 is electrically connected to the transceiver 100, and the transceiver 100 can receive the first auxiliary power signal from the first auxiliary coupler 140.

[0058] The radio frequency transceiver 10 provided in this application includes a switching switch 60. The switching switch 60 allows the first power coupler 120 to be electrically connected to the transceiver 100, and also allows the first auxiliary coupler 140 to be electrically connected to the transceiver 100, thereby enabling the transceiver 100 to receive the first power signal and the first auxiliary power signal. The transceiver 100 can determine whether the radio frequency transceiver 10 is in a conducted test state or a complete system state based on the first power signal fed back by the first power coupler 120 and the first auxiliary power signal fed back by the first auxiliary coupler 140. This improves the accuracy, reliability, and consistency of determining whether the radio frequency transceiver 10 is in a conducted test state or a complete system state.

[0059] Please see Figure 6 , Figure 6This is a schematic diagram of a radio frequency transceiver device provided in another embodiment of this application. The transceiver 100 is also used to transmit a second radio frequency signal. The switching switch 60 also has a third connection terminal 630 and a fourth connection terminal 640. The radio frequency transceiver device 10 further includes a second radio frequency front-end module 210, a second power coupler 220, a second test socket 230, a second auxiliary coupler 240, and a second radiator 250. The second radio frequency front-end module 210 is electrically connected to the transceiver 100 and is used to amplify the power of the second radio frequency signal. The second power coupler 220 is electrically connected to the second radio frequency front-end module 210 and the third connection terminal 630. The second test socket 230 is electrically connected to the second power coupler 220. The second auxiliary coupler 240 is electrically connected to the second test socket 230 and the fourth connection terminal 640. The second radiator 250 is electrically connected to the second auxiliary coupler 240, and the second radiator 250 is excited by the second radio frequency signal to generate an electromagnetic wave signal in a second frequency band. If the common terminal 600 is electrically connected to the third connection terminal 630, the transceiver 100 is electrically connected to the second power coupler 220, and the transceiver 100 is used to receive the second power signal from the second power coupler 220. If the common terminal 600 is electrically connected to the fourth connection terminal 640, the transceiver 100 is electrically connected to the second auxiliary coupler 240, and the transceiver 100 is used to receive the second auxiliary power signal from the second auxiliary coupler 240. The transceiver 100 is also used to determine whether the RF transceiver device 10 is in a conducted test state or a complete device state based on the second power signal and the second auxiliary power signal. Wherein, if the RF transceiver device 10 is in a conducted test state, the second RF signal is output to the tester via the second test socket 230 and cannot be transmitted to the second auxiliary coupler 240; if the RF transceiver device 10 is in a complete device state, the second RF signal is transmitted to the second radiator 250 via the second test socket 230 and the second auxiliary coupler 240.

[0060] In one embodiment, the common terminal 600 of the switch 60 can be electrically connected to any one of the first connection terminal 610, the second connection terminal 620, the third connection terminal 630, and the fourth connection terminal 640. If the common terminal 600 of the switch 60 is electrically connected to one of the first connection terminal 610, the second connection terminal 620, the third connection terminal 630, and the fourth connection terminal 640, the common terminal 600 is disconnected from the other three. For example, if the common terminal 600 of the switch 60 is electrically connected to the first connection terminal 610, the common terminal 600 is disconnected from the second connection terminal 620, the common terminal 600 is disconnected from the third connection terminal 630, and the common terminal 600 is disconnected from the fourth connection terminal 640. Therefore, in this embodiment, the switch 60 is also called a single-pole four-throw switch. That is, the switch 60 is an SPnT switch, where n = 4.

[0061] If the common terminal 600 is electrically connected to the first connection terminal 610, the first power coupler 120 is electrically connected to the transceiver 100, and the transceiver 100 can receive the first power signal from the first power coupler 120. If the common terminal 600 is electrically connected to the second connection terminal 620, the first auxiliary coupler 140 is electrically connected to the transceiver 100, and the transceiver 100 can receive the first auxiliary power signal from the first auxiliary coupler 140. Correspondingly, if the common terminal 600 is electrically connected to the third connection terminal 630, the second power coupler 220 is electrically connected to the transceiver 100, and the transceiver 100 can receive the second power signal from the second power coupler 220. If the common terminal 600 is electrically connected to the fourth connection terminal 640, the second auxiliary coupler 240 is electrically connected to the transceiver 100, and the transceiver 100 can receive the second auxiliary power signal from the second auxiliary coupler 240.

[0062] The transceiver 100 is used to transmit a second radio frequency signal, which is used to excite the second radiator 250 to generate an electromagnetic wave signal in a second frequency band. In other embodiments, the second radiator 250 receives the electromagnetic wave signal in the second frequency band and converts it into a radio frequency signal. For ease of naming, the second radiator 250 receives the electromagnetic wave signal in the second frequency band and names the signal obtained by converting it into a second signal. The transceiver 100 is also used to receive the second signal.

[0063] The second RF front-end module 210 is used to amplify the power of the second RF signal. The amplified second RF signal is output to the second power coupler 220. In one embodiment, the second RF front-end module 210 includes a power amplifier; for ease of description, the power amplifier of the second RF front-end module 210 is referred to as the second power amplifier. The second power amplifier is used to amplify the power of the second RF signal.

[0064] If the second radiator 250 receives an electromagnetic wave signal in the second frequency band, it converts the electromagnetic wave signal in the second frequency band into a second signal. The second radio frequency front-end module 210 is also used to perform low-noise power amplification on the second signal. In one embodiment, the second radio frequency front-end module 210 further includes a low-noise amplifier; for ease of description, the low-noise amplifier of the second radio frequency front-end module 210 is named a second low-noise amplifier. The second low-noise amplifier is used to perform low-noise power amplification on the second signal. The second signal after low-noise power amplification is transmitted to the transceiver 100.

[0065] The second power coupler 220 is electrically connected to the second RF front-end module 210 and is used to receive the amplified second RF signal output from the second RF front-end module 210. The second power coupler 220 couples the amplified second RF signal output from the second RF front-end module 210 to obtain a second power signal. The second power coupler 220 is electrically connected to the transceiver 100 to output the second power signal to the transceiver 100.

[0066] The second test socket 230 is electrically connected to the second power coupler 220. If testing of the RF transceiver 10 is required, a tester can be electrically connected to the second test socket 230 for testing. If the RF transceiver 10 is in a conducted test state, the second test socket 230 is used to electrically connect to the tester. The second RF signal cannot be conducted to the second auxiliary coupler 240 via the second test socket 230. If the RF transceiver 10 is in a fully functional state, the second RF signal can be conducted to the second auxiliary coupler 240 via the second test socket 230 and then to the second radiator 250.

[0067] The second auxiliary coupler 240 is electrically connected to the second test socket 230, coupling the amplified second radio frequency signal output from the second radio frequency front-end module 210 to obtain the second auxiliary power signal. The second auxiliary coupler 240 can also be referred to as the second auxiliary power coupler. The second auxiliary coupler 240 is electrically connected to the transceiver 100 to output the second auxiliary power signal to the transceiver 100.

[0068] Therefore, as described above, if the RF transceiver 10 is in the conducted test state (also known as the conducted state or board-level state), the transmission path of the second RF signal emitted by the transceiver 100 is: transceiver 100, second RF front-end module 210, second power coupler 220, second test socket 230, and tester. Thus, if the RF transceiver 10 is in the conducted test state (also known as the board-level state): the second power coupler 220 can couple the second RF signal amplified by the second RF front-end module 210, while the second auxiliary coupler 240 cannot couple to the second RF signal amplified by the second RF front-end module 210. Therefore, if the RF transceiver 10 is in the conducted test state, the difference between the second power signal and the second auxiliary power signal is significant.

[0069] If the RF transceiver 10 is in its complete state, the transmission path of the second RF signal emitted by the transceiver 100 is: transceiver 100, second RF front-end module 210, second power coupler 220, second test socket 230, second auxiliary power coupler, and second radiator 250. Therefore, if the RF transceiver 10 is in its complete state: the second power coupler 220 can couple the second RF signal amplified by the second RF front-end module 210, and the second auxiliary coupler 240 can couple to the second RF signal amplified by the second RF front-end module 210. Therefore, if the RF transceiver 10 is in its complete state, the second power signal and the second auxiliary power signal are equal or approximately equal.

[0070] The transceiver 100 is electrically connected to the second power coupler 220 to receive the second power signal fed back by the second power coupler 220; and the transceiver 100 is electrically connected to the second auxiliary power coupler to receive the second auxiliary power signal fed back by the second auxiliary power coupler. The transceiver 100 determines whether the RF transceiver device 10 is in a conducted test state or a complete system state based on the second power signal and the second auxiliary power signal. Therefore, the RF transceiver device 10 provided in this embodiment can effectively distinguish between the conducted test state and the complete system state. Thus, the air interface detection mechanism of the RF transceiver device 10 provided in this embodiment is more reliable and has better consistency than related technologies.

[0071] In summary, the RF transceiver 10 provided in this application includes not only a second power coupler 220 located between the second RF front-end module and the second test socket 230, but also a second auxiliary coupler 240 located between the second test socket 230 and the second radiator 250. If the RF transceiver 10 is in a conducted test state, the second RF signal is output to the tester via the second test socket 230 and cannot be output to the second auxiliary coupler 240. If the RF transceiver 10 is in a complete unit state, the second RF signal can be transmitted to the second auxiliary coupler 240 via the second test socket 230. Therefore, the transceiver 100 can determine whether the RF transceiver 10 is in a conducted test state or a complete unit state based on the second power signal fed back by the second power coupler 220 and the second auxiliary power signal fed back by the second auxiliary coupler 240. This improves the accuracy, reliability, and consistency of determining whether the RF transceiver 10 is in a conducted test state or a complete unit state.

[0072] Furthermore, in one embodiment of the radio frequency transceiver device 10, the transceiver 100 determines whether the radio frequency transceiver device 10 is in a conducted test state using the first power signal and the first auxiliary power signal, and the transceiver 100 determines whether the radio frequency transceiver device 10 is in a conducted test state using the second power signal and the second auxiliary power signal; the transceiver 100 determines that the radio frequency transceiver device 100 is in a conducted test state. Correspondingly, in one embodiment of the radio frequency transceiver device 10, the transceiver 100 determines whether the radio frequency transceiver device 10 is in a complete unit state using the first power signal and the first auxiliary power signal, and the transceiver 100 determines whether the radio frequency transceiver device 10 is in a complete unit state using the second power signal and the second auxiliary power signal; the transceiver 100 determines that the radio frequency transceiver device 100 is in a complete unit state. This improves the accuracy of the transceiver 100 in determining whether the radio frequency transceiver device 10 is in a conducted test state or a complete unit state.

[0073] Further, in one embodiment, the ratio of the second power signal to the second auxiliary power signal is a second ratio X2. If the second ratio X2 satisfies: X2 > 10, the transceiver 100 determines that the RF transceiver device 10 is in a conducted test state. If the second ratio X2 satisfies: 0.5 ≤ X2 ≤ 1.5, the transceiver 100 determines that the RF transceiver device 10 is in a complete unit state.

[0074] As described above, if the RF transceiver 10 is in a conducted test state: the second power coupler 220 can couple the second RF signal amplified by the second RF front-end module 210, while the second auxiliary coupler 240 cannot couple to the second RF signal amplified by the second RF front-end module 210. Therefore, if the RF transceiver 10 is in a conducted test state, the difference between the second power signal and the second auxiliary power signal is large, and the second ratio X2 is much greater than 10. Therefore, if the second ratio X2 satisfies: X2 > 10, the transceiver 100 determines that the RF transceiver 10 is in a conducted test state.

[0075] Furthermore, as described above, if the RF transceiver 10 is in its complete state: the second power coupler 220 can couple the second RF signal amplified by the second RF front-end module 210, and the second auxiliary coupler 240 can couple to the second RF signal amplified by the second RF front-end module 210. Therefore, if the RF transceiver 10 is in its complete state, the second power signal and the second auxiliary power signal are equal or approximately equal. The second ratio X2 is small, equal to or close to 1. Therefore, if the second ratio X2 satisfies: 0.5 ≤ X2 ≤ 1.5, the transceiver 100 determines that the RF transceiver 10 is in its complete state.

[0076] The radio frequency transceiver 10 provided in this application embodiment has a second ratio value X2 as the ratio of the second power to the second auxiliary power. The transceiver 100 uses the magnitude of the second ratio value X2 to determine whether the radio frequency transceiver 10 is in a conducted test state or a complete unit state. This improves the accuracy, reliability, and consistency of determining whether the radio frequency transceiver 10 is in a conducted test state or a complete unit state.

[0077] In one embodiment, the first frequency band is equal to the second frequency band; or, the first frequency band is not equal to the second frequency band.

[0078] The radio frequency transceiver 10 provided in this application does not limit the relationship between the first frequency band and the second frequency band. The first frequency band may be equal to the second frequency band. The first frequency band may also not be equal to the second frequency band.

[0079] If the first frequency band is equal to the second frequency band, the radio frequency transceiver 10 can realize dual-channel multiple-input multiple-output (MIMO) of the first frequency band to improve the communication performance of the first frequency band.

[0080] Further, please refer to Figure 7 , Figure 7This is a schematic diagram of a radio frequency transceiver device according to another embodiment of this application. In one embodiment, the radio frequency transceiver device 10 includes a circuit board 40. The transceiver 100, the first radio frequency front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all located on the circuit board 40. The switching switch 60, the second radio frequency front-end module 210, the second power coupler 220, the second test socket 230, and the second auxiliary coupler 240 are all located on the circuit board 40.

[0081] The circuit board 40 can be, but is not limited to, a printed circuit board (PCBA). In this embodiment, the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all located on the circuit board 40. For example, the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all surface-mounted on the circuit board 40. The transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 can be electrically connected, but is not limited to, through wiring connections on the conductive layer of the circuit board 40.

[0082] The transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all located on the circuit board 40. Therefore, the electrical connection between the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 is relatively reliable, thereby improving the accuracy, reliability, and consistency of determining whether the RF transceiver device 10 is in a conducted test state or a complete unit state.

[0083] Further, in this embodiment, the switching switch 60, the second RF front-end module 210, the second power coupler 220, the second test socket 230, and the second auxiliary coupler 240 are all located on the circuit board 40. For example, the switching switch 60, the second RF front-end module 210, the second power coupler 220, the second test socket 230, and the second auxiliary coupler 240 are all surface-mounted on the circuit board 40. The electrical connection method of the switching switch 60, the second RF front-end module 210, the second power coupler 220, the second test socket 230, and the second auxiliary coupler 240 can be, but is not limited to, electrical connection through the wiring layer of the conductive layer of the circuit board 40. The switching switch 60, the second RF front-end module 210, the second power coupler 220, the second test socket 230, and the second auxiliary coupler 240 are all located on the circuit board 40. Therefore, the connection between the switching switch 60, the second RF front-end module 210, the second power coupler 220, the second test socket 230, and the second auxiliary coupler 240 is relatively reliable, thereby improving the accuracy, reliability, and consistency of determining whether the RF transceiver 10 is in a conducted test state or a complete unit state.

[0084] Please see Figure 8 , Figure 8This is a schematic diagram of a radio frequency transceiver device provided in another embodiment of this application. The transceiver 100 is also used to transmit a third radio frequency signal. The switching switch 60 also has a fifth connection terminal 650 and a sixth connection terminal 660. The radio frequency transceiver device 10 further includes a third radio frequency front-end module 310, a third power coupler 320, a third test socket 330, a third auxiliary coupler 340, and a third radiator 350. The third radio frequency front-end module 310 is electrically connected to the transceiver 100 and is used to amplify the power of the third radio frequency signal. The third power coupler 320 is electrically connected to the third radio frequency front-end module 310 and the fifth connection terminal 650. The third test socket 330 is electrically connected to the third power coupler 320. The third auxiliary coupler 340 is electrically connected to the third test socket 330 and the sixth connection terminal 660. The third radiator 350 is electrically connected to the third auxiliary coupler 340, and the third radiator 350 is excited by the second radio frequency signal to generate an electromagnetic wave signal in a third frequency band. If the common terminal 600 is electrically connected to the fifth connection terminal 650, the transceiver 100 is electrically connected to the third power coupler 320, and the transceiver 100 is used to receive the third power signal from the third power coupler 320. If the common terminal 600 is electrically connected to the sixth connection terminal 660, the transceiver 100 is electrically connected to the third auxiliary coupler 340, and the transceiver 100 is used to receive the third auxiliary power signal from the third auxiliary coupler 340. The transceiver 100 is also used to determine whether the RF transceiver device 10 is in a conducted test state or a complete unit state based on the third power signal and the third auxiliary power signal. Wherein, if the RF transceiver device 10 is in a conducted test state, the third RF signal is output to the tester via the third test socket 330 and cannot be transmitted to the third auxiliary coupler 340. If the RF transceiver device 10 is in a complete unit state, the third RF signal is transmitted to the third radiator 350 via the third test socket 330 and the third auxiliary coupler 340.

[0085] In one embodiment, the common terminal 600 of the switch 60 can be electrically connected to any one of the first connection terminal 610, the second connection terminal 620, the third connection terminal 630, the fourth connection terminal 640, the fifth connection terminal 650, and the sixth connection terminal 660. If the common terminal 600 of the switch 60 is electrically connected to one of the first connection terminal 610, the second connection terminal 620, the third connection terminal 630, the fourth connection terminal 640, the fifth connection terminal 650, and the sixth connection terminal 660, the common terminal 600 is disconnected from the other five. For example, if the common terminal 600 of the switch 60 is electrically connected to the first connection terminal 610, the common terminal 600 is disconnected from the second connection terminal 620, the common terminal 600 is disconnected from the third connection terminal 630, the common terminal 600 is disconnected from the fourth connection terminal 640, the common terminal 600 is disconnected from the fifth connection terminal 650, and the common terminal 600 is disconnected from the sixth connection terminal 660. Therefore, in this embodiment, the switch 60 is also called a single-pole six-throw switch. That is, the switch 60 is an SPnT switch, where n = 6.

[0086] If the common terminal 600 is electrically connected to the first connection terminal 610, the first power coupler 120 is electrically connected to the transceiver 100, and the transceiver 100 can receive the first power signal from the first power coupler 120. If the common terminal 600 is electrically connected to the second connection terminal 620, the first auxiliary coupler 140 is electrically connected to the transceiver 100, and the transceiver 100 can receive the first auxiliary power signal from the first auxiliary coupler 140. Correspondingly, if the common terminal 600 is electrically connected to the third connection terminal 630, the second power coupler 220 is electrically connected to the transceiver 100, and the transceiver 100 can receive the second power signal from the second power coupler 220. If the common terminal 600 is electrically connected to the fourth connection terminal 640, the second auxiliary coupler 240 is electrically connected to the transceiver 100, and the transceiver 100 can receive the second auxiliary power signal from the second auxiliary coupler 240. If the common terminal 600 is electrically connected to the fifth connection terminal 650, the third power coupler 320 is electrically connected to the transceiver 100, and the transceiver 100 can receive the third power signal from the third power coupler 320. If the common terminal 600 is electrically connected to the sixth connection terminal 660, the transceiver 100 is electrically connected to the third auxiliary coupler 340, and the transceiver 100 can receive the third auxiliary power signal from the third auxiliary coupler 340.

[0087] The transceiver 100 is used to transmit a third radio frequency signal, which is used to excite the third radiator 350 to generate an electromagnetic wave signal in a third frequency band. In other embodiments, the third radiator 350 receives the electromagnetic wave signal in the third frequency band and converts it into a radio frequency signal. For ease of naming, the third radiator 350 receives the electromagnetic wave signal in the third frequency band and names the signal obtained by converting it into a third signal. The transceiver 100 is also used to receive the third signal.

[0088] The third RF front-end module 310 is used to amplify the power of the third RF signal. The amplified third RF signal is output to the third power coupler 320. In one embodiment, the third RF front-end module 310 includes a power amplifier; for ease of description, the power amplifier of the third RF front-end module 310 is referred to as the third power amplifier. The third power amplifier is used to amplify the power of the third RF signal.

[0089] If the third radiator 350 receives an electromagnetic wave signal in the third frequency band, it converts the electromagnetic wave signal in the third frequency band into a third signal. The third radio frequency front-end module 310 is also used to amplify the third signal with low noise power. In one embodiment, the third radio frequency front-end module 310 further includes a low noise amplifier; for ease of description, the low noise amplifier of the third radio frequency front-end module 310 is named a third low noise amplifier. The third low noise amplifier is used to amplify the third signal with low noise power. The third signal after low noise power amplification is transmitted to the transceiver 100.

[0090] The third power coupler 320 is electrically connected to the third RF front-end module 310 and is used to receive the amplified third RF signal output from the third RF front-end module 310. The third power coupler 320 couples the amplified third RF signal output from the third RF front-end module 310 to obtain a third power signal. The third power coupler 320 is electrically connected to the transceiver 100 to output the third power signal to the transceiver 100.

[0091] The third test socket 330 is electrically connected to the third power coupler 320. If testing of the RF transceiver 10 is required, a tester can be electrically connected to the third test socket 330 for testing. If the RF transceiver 10 is in a conducted test state, the third test socket 330 is used to electrically connect to the tester. The third RF signal cannot be conducted to the third auxiliary coupler 340 via the third test socket 330. If the RF transceiver 10 is in a complete unit state, the third RF signal can be conducted to the third auxiliary coupler 340 via the third test socket 330 and then to the third radiator 350.

[0092] The third auxiliary coupler 340 is electrically connected to the third test socket 330, coupling the amplified third radio frequency signal output from the third radio frequency front-end module 310 to obtain a third auxiliary power signal. The third auxiliary coupler 340 can also be referred to as a third auxiliary power coupler. The third auxiliary coupler 340 is electrically connected to the transceiver 100 to output the third auxiliary power signal to the transceiver 100.

[0093] Therefore, as described above, if the RF transceiver 10 is in the conducted test state (also known as the board-level state), the transmission path of the third RF signal emitted by the transceiver 100 is: transceiver 100, third RF front-end module 310, third power coupler 320, third test socket 330, and tester. Thus, if the RF transceiver 10 is in the conducted test state (also known as the board-level state): the third power coupler 320 can couple the third RF signal amplified by the third RF front-end module 310, while the third auxiliary coupler 340 cannot couple to the third RF signal amplified by the third RF front-end module 310. Therefore, it can be seen that if the RF transceiver 10 is in the conducted test state, the difference between the third power signal and the third auxiliary power signal is significant.

[0094] If the RF transceiver 10 is in its complete state, the transmission path of the third RF signal emitted by the transceiver 100 is: transceiver 100, the third RF front-end module 310, the third power coupler 320, the third test socket 330, the third auxiliary power coupler, and the third radiator 350. Therefore, if the RF transceiver 10 is in its complete state: the third power coupler 320 can couple the third RF signal amplified by the third RF front-end module 310, and the third auxiliary coupler 340 can couple to the third RF signal amplified by the third RF front-end module 310. Therefore, if the RF transceiver 10 is in its complete state, the third power signal and the third auxiliary power signal are equal or approximately equal.

[0095] The transceiver 100 is electrically connected to the third power coupler 320 to receive the third power signal fed back by the third power coupler 320; and the transceiver 100 is electrically connected to the third auxiliary power coupler to receive the third auxiliary power signal fed back by the third auxiliary power coupler. The transceiver 100 determines whether the RF transceiver device 10 is in a conducted test state or a complete unit state based on the third power signal and the third auxiliary power signal. Therefore, the RF transceiver device 10 provided in this embodiment can effectively distinguish between the conducted test state and the complete unit state. Thus, the air interface detection mechanism of the RF transceiver device 10 provided in this embodiment is more reliable and has better consistency than related technologies.

[0096] In summary, the RF transceiver 10 provided in this application includes not only a third power coupler 320 located between the third RF front-end module and the third test socket 330, but also a third auxiliary coupler 340 located between the third test socket 330 and the third radiator 350. If the RF transceiver 10 is in a conducted test state, the third RF signal is output to the tester via the third test socket 330 and cannot be output to the third auxiliary coupler 340. If the RF transceiver 10 is in a complete unit state, the third RF signal can be transmitted to the third auxiliary coupler 340 via the third test socket 330. Therefore, the transceiver 100 can determine whether the RF transceiver 10 is in a conducted test state or a complete unit state based on the third power signal fed back by the third power coupler 320 and the third auxiliary power signal fed back by the third auxiliary coupler 340. This improves the accuracy, reliability, and consistency of determining whether the RF transceiver 10 is in a conducted test state or a complete unit state.

[0097] In one embodiment, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 constitute a path, referred to as the first path. Correspondingly, the second RF front-end module 210, the second power coupler 220, the second test socket 230, and the second auxiliary coupler 240 constitute a path, referred to as the second path. The third RF front-end module 310, the third power coupler 320, the third test socket 330, and the third auxiliary coupler 340 constitute a path, referred to as the third path.

[0098] In one embodiment, the first power signal and the first auxiliary power signal of the first path, the second power signal and the second auxiliary power signal of the second path, and the third power signal and the third auxiliary power signal of the third path are transmitted to the transceiver 100 via the common terminal 600 through the switching switch 60. Therefore, it can also be said that the detection signals of the first path (i.e., the first power signal and the first auxiliary power signal), the second path (i.e., the second power signal and the second auxiliary power signal), and the third path (i.e., the third power signal and the third auxiliary power signal) respectively enter the switching switch 60 and are then combined into one channel to enter the transceiver 100.

[0099] Furthermore, in one embodiment of this application, the radio frequency transceiver 10 is provided, wherein the transceiver 100 determines that the radio frequency transceiver 10 is in a conducted test state using the first power signal and the first auxiliary power signal, and the transceiver 100 determines that the radio frequency transceiver 10 is in a conducted test state using the second power signal and the second auxiliary power signal; and the transceiver 100 determines that the radio frequency transceiver 100 is in a conducted test state using the third power signal and the third auxiliary power signal; the transceiver 100 determines that the radio frequency transceiver 100 is in a conducted test state. Accordingly, in one embodiment of this application, the radio frequency transceiver 10 is provided, wherein the transceiver 100 determines that the radio frequency transceiver 10 is in a complete unit state using the first power signal and the first auxiliary power signal, and the transceiver 100 determines that the radio frequency transceiver 10 is in a complete unit state using the second power signal and the second auxiliary power signal; and the transceiver 100 determines that the radio frequency transceiver 10 is in a complete unit state using the third power signal and the third auxiliary power signal; the transceiver 100 determines that the radio frequency transceiver 100 is in a complete unit state. Thus, the accuracy of the transceiver 100 in determining whether the radio frequency transceiver 10 is in a conducted test state or a complete unit state can be improved.

[0100] It should be noted that the RF transceiver 10 provided in this application embodiment has a first path, a second path, and a third path. The transceiver 100 determines whether the RF transceiver 10 is in a conducted test state or a complete unit state using the first power signal and the first auxiliary power signal in the first path. Correspondingly, in another embodiment, the transceiver 100 can also determine whether the RF transceiver 10 is in a conducted test state or a complete unit state using the first power signal and the first auxiliary power signal of the first path, and the second power signal and the second auxiliary power signal of the second path. Correspondingly, in yet another embodiment, the transceiver 100 can also determine whether the RF transceiver 10 is in a conducted test state or a complete unit state using the first power signal and the first auxiliary power signal of the first path, and the second power signal and the second auxiliary power signal of the second path, as well as the third power signal and the third auxiliary power signal in the second path. The transceiver 100 can select an appropriate number of paths to determine whether the RF transceiver 10 is in a conducted test state or a complete unit state based on the actual situation.

[0101] Further, the ratio of the third power signal to the third auxiliary power signal is a third ratio X3. If the third ratio X3 satisfies: X3 > 10, the transceiver 100 determines that the RF transceiver device 10 is in a conducted test state. If the third ratio X3 satisfies: 0.5 ≤ X3 ≤ 1.5, the transceiver 100 determines that the RF transceiver device 10 is in a complete unit state.

[0102] As described above, if the RF transceiver 10 is in a conducted test state: the third power coupler 320 can couple the third RF signal amplified by the third RF front-end module 310, while the third auxiliary coupler 340 cannot couple to the third RF signal amplified by the third RF front-end module 310. Therefore, if the RF transceiver 10 is in a conducted test state, the difference between the third power signal and the third auxiliary power signal is significant, and the third ratio X3 is much greater than 10. Therefore, if the third ratio X3 satisfies: X3 > 10, the transceiver 100 determines that the RF transceiver 10 is in a conducted test state.

[0103] Furthermore, as described above, if the RF transceiver 10 is in its complete state: the third power coupler 320 can couple the third RF signal amplified by the third RF front-end module 310, and the third auxiliary coupler 340 can couple to the third RF signal amplified by the third RF front-end module 310. Therefore, if the RF transceiver 10 is in its complete state, the third power signal and the third auxiliary power signal are equal or approximately equal. The third ratio X3 is small, equal to or close to 1. Therefore, if the third ratio X3 satisfies: 0.5 ≤ X3 ≤ 1.5, the transceiver 100 determines that the RF transceiver 10 is in its complete state.

[0104] The radio frequency transceiver 10 provided in this application embodiment has a third ratio value X3 as the ratio of the third power to the third auxiliary power. The transceiver 100 uses the magnitude of the third ratio value X3 to determine whether the radio frequency transceiver 10 is in a conducted test state or a complete unit state. This improves the accuracy, reliability, and consistency of determining whether the radio frequency transceiver 10 is in a conducted test state or a complete unit state.

[0105] The radio frequency transceiver 10 provided in this application does not limit the relationship between the first frequency band and the second frequency band. The first frequency band may be equal to the second frequency band. The first frequency band may also not be equal to the second frequency band.

[0106] If the first frequency band is equal to the second frequency band, the radio frequency transceiver 10 can realize dual-channel multiple-input multiple-output (MIMO) of the first frequency band to improve the communication performance of the first frequency band.

[0107] Accordingly, the radio frequency transceiver 10 provided in this application does not limit the relationship between the third frequency band and the first frequency band, nor does it limit the relationship between the third frequency band and the second frequency band. In one embodiment, the third frequency band is equal to the first frequency band; in another embodiment, the third frequency band is not equal to the first frequency band.

[0108] Further, please refer to Figure 9 , Figure 9 This is a schematic diagram of a radio frequency transceiver device provided in another embodiment of this application. The radio frequency transceiver device 10 includes a circuit board 40.

The switching switch 60, the third radio frequency front-end module 310, the third power coupler 320, the third test socket 330, and the third auxiliary coupler 340 are all located on the circuit board 40.

[0109] The circuit board 40 can be, but is not limited to, a printed circuit board (PCBA). In this embodiment, the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all located on the circuit board 40. For example, the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all surface-mounted on the circuit board 40. The transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 can be electrically connected, but is not limited to, through wiring connections on the conductive layer of the circuit board 40.

[0110] The transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 are all located on the circuit board 40. Therefore, the electrical connection between the transceiver 100, the first RF front-end module 110, the first power coupler 120, the first test socket 130, and the first auxiliary coupler 140 is relatively reliable, thereby improving the accuracy, reliability, and consistency of determining whether the RF transceiver device 10 is in a conducted test state or a complete unit state.

[0111] Furthermore, in this embodiment, the switching switch 60, the third RF front-end module 310, the third power coupler 320, the third test socket 330, and the third auxiliary coupler 340 are all located on the circuit board 40. For example, the switching switch 60, the third RF front-end module 310, the third power coupler 320, the third test socket 330, and the third auxiliary coupler 340 are all surface-mounted on the circuit board 40. The electrical connection method of the switching switch 60, the third RF front-end module 310, the third power coupler 320, the third test socket 330, and the third auxiliary coupler 340 can be, but is not limited to, electrical connection through the wiring layer of the conductive layer of the circuit board 40. The switching switch 60, the third RF front-end module 310, the third power coupler 320, the third test socket 330, and the third auxiliary coupler 340 are all located on the circuit board 40. Therefore, the connection between the switching switch 60, the third RF front-end module 310, the third power coupler 320, the third test socket 330, and the third auxiliary coupler 340 is relatively reliable, thereby improving the accuracy, reliability, and consistency of determining whether the RF transceiver 10 is in a conducted test state or a complete unit state.

[0112] In one embodiment, the transceiver 100 transmits a first radio frequency signal with a first preset power, and the first power signal from the first power coupler 120 has a first detected power. If the difference between the first detected power and the first preset power is greater than or equal to a first preset threshold, the transceiver 100 adjusts the first preset power of the first radio frequency signal according to the first preset power and the first detected power, so that the difference between the adjusted first preset power of the first radio frequency signal and the first detected power obtained from the adjusted first radio frequency signal is less than the first preset threshold. This allows for precise control of the first radio frequency signal. In other words, the radio frequency transceiver 10 provided in this application embodiment can perform real-time and precise power control using the strength of the first power signal fed back by the first power coupler 120.

[0113] In one embodiment, the transceiver 100 transmits a second radio frequency signal at a second preset power, and the second power signal from the second power coupler 220 is a second detected power. If the difference between the second detected power and the second preset power is greater than or equal to a second preset threshold, the transceiver 100 adjusts the second preset power of the second radio frequency signal according to the second preset power and the second detected power, so that the difference between the adjusted second preset power of the second radio frequency signal and the second detected power obtained from the adjusted second radio frequency signal is less than the second preset threshold. This allows for precise control of the second radio frequency signal. In other words, the radio frequency transceiver device 10 provided in this application embodiment can perform real-time and precise power control using the strength of the second power signal fed back by the second power coupler 220.

[0114] In one embodiment, the transceiver 100 transmits a third radio frequency signal at a third preset power, and the third power signal from the third power coupler 320 is a third detected power. If the difference between the third detected power and the third preset power is greater than or equal to a third preset threshold, the transceiver 100 adjusts the third preset power of the third radio frequency signal according to the third preset power and the third detected power, so that the difference between the adjusted third preset power of the third radio frequency signal and the third detected power obtained from the adjusted third radio frequency signal is less than the third preset threshold. This allows for precise control of the third radio frequency signal. In other words, the radio frequency transceiver 10 provided in this application embodiment can perform real-time and precise power control using the strength of the third power signal fed back by the third power coupler 320.

[0115] In summary, this application provides a radio frequency transceiver device 10, which includes a first power coupler 120 and a first auxiliary coupler 140. Therefore, the radio frequency transceiver device 10 can also be referred to as including a dual-coupled power coupler. The radio frequency transceiver device 10 provided in this application is a dual-coupled power coupler design. The transceiver 100 uses the first power signal fed back from the first power coupler 120 and the first auxiliary power signal fed back from the first auxiliary coupler 140 to determine whether the radio frequency transceiver device 10 is in a conducted test state or a complete unit state. Therefore, the radio frequency transceiver device 10 of this application can also be referred to as a dual-coupled power design calculation air interface detection scheme. The air interface detection scheme provided in this application is more reliable and has better consistency than the schemes in related technologies.

[0116] This application also provides an electronic device 1 in one embodiment. The electronic device 1 may be a mobile phone, tablet computer, desktop computer, laptop computer, e-reader, handheld computer, electronic display screen, laptop computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR) / virtual reality (VR) device, media player, smart wearable device, etc.

[0117] Please see Figure 10 , Figure 10 This is a schematic diagram of an electronic device provided according to one embodiment of this application. The electronic device 1 includes a radio frequency transceiver 10. The radio frequency transceiver 10 can be any of the radio frequency transceiver 10 provided in the preceding embodiments.

[0118] Furthermore, in one embodiment, the transceiver 100 is also configured to execute a corresponding power control strategy based on the current state of the radio frequency transceiver device 10 and the current posture of the electronic device 1; wherein the current state includes either a conducted test state or an overall state, and the current posture of the electronic device 1 includes either a hand state or a head-and-hand state.

[0119] The term "hand position" refers to the state where the electronic device 1 is held by the user's hand and is away from the user's head. The term "head-and-hand position" refers to the state where the electronic device 1 is held by the user's hand and placed next to the head. For example, when a user is holding the electronic device 1 to make a phone call, the electronic device 1 is typically in the head-and-hand position. However, when a user is holding the electronic device 1 to watch a video, the electronic device 1 is in the hand position.

[0120] The electronic device 1 provided in this application embodiment has a transceiver 100 that executes a corresponding power control strategy on the radio frequency transceiver 10 according to the current state of the radio frequency transceiver 10 and the current attitude of the electronic device 1, thereby making the power control of the radio frequency transceiver 10 more accurate.

[0121] Further, in one embodiment, if the current posture of the electronic device 1 is a human head and hand state, and the current state of the radio frequency transceiver device 10 is a complete machine state; if the transmission power of the first radio frequency signal exceeds the first preset power, the transceiver 100 reduces the transmission power of the first radio frequency signal, and makes the SAR value corresponding to the power of the reduced first radio frequency signal within the monitoring window period less than the safety SAR value, wherein the SAR value corresponding to the first preset power is greater than or equal to the safety SAR value.

[0122] SAR stands for Specific Absorption Rate. To ensure the safety of electromagnetic signal transmission and reception by the radio frequency transceiver 10, SAR regulatory agencies in different countries and regions regulate the transmission power of the radio frequency signals transmitted by the transceiver 10 within a monitoring window to ensure that the average SAR value within the monitoring window does not exceed the safety SAR value. For example, the U.S. Federal Communications Commission (FCC) stipulates that for radio frequency signals below 3 GHz, the monitoring window is 100 seconds, and the average SAR value within 100 seconds must not exceed 1.6 W / Kg; for radio frequency signals above 3 GHz, the monitoring window is 60 seconds, and the average SAR value within 60 seconds must not exceed 1.6 W / Kg.

[0123] In this embodiment, if the current state of the electronic device 1 is a human head and hand state, and the current state of the radio frequency transceiver device 10 is a complete unit state, and the transmission power of the first radio frequency signal exceeds the preset frequency, the transceiver 100 reduces the transmission power of the first radio frequency signal, and makes the SAR value corresponding to the power of the first radio frequency signal after reduction less than the safety SAR value within the monitoring window duration. Thus, when the electronic device 1 is in a human head and hand state and the radio frequency transceiver device 10 is in a complete unit state, the SAR value of the first radio frequency signal is prevented from exceeding the standard within the detection window duration.

[0124] In one embodiment, if the current posture of the electronic device 1 is a human head and hand state, and the current state of the radio frequency transceiver device 10 is a complete machine state; if the transmission power of the second radio frequency signal exceeds the second preset power, the transceiver 100 reduces the transmission power of the second radio frequency signal, and makes the SAR value corresponding to the power of the reduced second radio frequency signal within the monitoring window period less than the safety SAR value, wherein the SAR value corresponding to the second preset power is greater than or equal to the safety SAR value.

[0125] Accordingly, if the current posture of the electronic device 1 is a human head and hand state, and the current state of the radio frequency transceiver device 10 is a complete machine state; if the transmission power of the third radio frequency signal exceeds the third preset power, the transceiver 100 reduces the transmission power of the third radio frequency signal, and makes the SAR value corresponding to the power of the reduced third radio frequency signal within the monitoring window period less than the safety SAR value, wherein the SAR value corresponding to the third preset power is greater than or equal to the safety SAR value.

[0126] In one embodiment, the electronic device 1 further includes a mid-frame 30, a display screen 50, and a back cover 70. The display screen 50 is disposed on one side of the mid-frame 30. The display screen 50 is the component in the electronic device 1 that implements the display function. The display screen 50 can be, but is not limited to, a screen with touch functionality, or a screen without touch functionality; this application does not limit this. The back cover 70 is disposed on the other side of the mid-frame 30. In other words, the back cover 70 and the display screen 50 are respectively disposed on opposite sides of the mid-frame 30. When the electronic device 1 also includes a battery, the back cover 70 is also called a battery cover. The material of the back cover 70 can be metal or non-metal; this embodiment does not limit this. It is understood that the description of the embodiments in this application is an introduction to an application environment of the radio frequency transceiver device and should not be construed as limiting the electronic device 1 provided in the embodiments of this application.

[0127] The above description represents some embodiments of this application.
