Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.

The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Embodiments of the present application are described below with reference to the accompanying drawings.
The technical scheme of the application can be applied to a structural schematic diagram of a radio frequency power detection circuit shown in fig. 1, wherein the radio frequency power detection circuit comprises a main circuit module 10, a microstrip line 20 and a detection module 30, and the microstrip line 20 and a wire 11 in the main circuit module 10 are arranged in parallel and can be coupled with the wire 11. One end of the microstrip line 20 is used for grounding, and the other end of the microstrip line 20 is used for being connected with the detection module 30 so as to detect and obtain the voltage of the microstrip line 20 at the end, and accordingly the radio frequency power of the radio frequency signal passing through the lead 11 is deduced according to the voltage of the end. The main circuit module may be a radio frequency power supply circuit. The conductive line may be a microstrip line, a strip line, or the like, and is not further limited herein.
Referring to fig. 2, fig. 2 is a flow chart of a radio frequency power detection method provided in an embodiment of the present application, where the method may be applied to a detection module of a radio frequency power detection circuit shown in fig. 1, the radio frequency power detection circuit includes a main circuit module and a microstrip line, the microstrip line and a wire in the main circuit module are arranged at intervals, and one end of the microstrip line is grounded, as shown in fig. 2, the radio frequency power detection method includes:
step S210, detecting a voltage of the microstrip line for grounding one end when the conductive wire is energized, so as to obtain a test voltage.
The microstrip line is used for grounding an isolation point of which one end is a preset microstrip line.
Step S220, determining whether the test voltage is zero.
Specifically, by detecting whether the test voltage is zero, it can be determined whether the microstrip line is used for grounding one end to meet the requirement of an isolation point, that is, whether the grounding one end is a point with equal electric field strength and magnetic field strength and opposite directions on the microstrip line.
It can be understood that when the wire is electrified, the microstrip line will be coupled with the wire, and the microstrip line will be subjected to the dual action of magnetic field and electric field under the influence of current, and the electric field value at a certain point on the microstrip line is The magnetic field value is +.>Wherein deltaE is the electric field strength at any point on the wire, d is the distance between the wire and the microstrip line, mu is the magnetic permeability, epsilon is the dielectric constant, L is the length of the microstrip line, and deltaI is the wire current. When the microstrip line is designed according to the coupling effect of the microstrip line and the lead, the microstrip line can be used for designing one end of the grounding as an isolation point, namely, the microstrip line is used for designing one end of the grounding as a point with equal electric field intensity and magnetic field intensity and opposite directions on the microstrip line, so that the voltage of the end of the microstrip line is zero, the effect is equivalent to grounding, and the influence of grounding on the voltage on the microstrip line is reduced. The ungrounded end of the microstrip line can be designed as a point with equal electric field intensity and magnetic field intensity and the same direction on the microstrip line, when the voltage of the microstrip line used for grounding the end is zero, the voltage of the microstrip line used for representing the radio frequency power can be obtained by detecting the voltage of the point, so that the radio frequency power of the radio frequency signal transmitted by the lead can be analyzed and calculated according to the voltage and the coupling effect of the microstrip line and the lead, namely the radio frequency power of the main circuit module. The coupling effect of the microstrip line and the wire can be analyzed and calculated by an electromagnetic field simulation method.
And step S230, if yes, detecting a target voltage of an ungrounded end of the microstrip line, and determining the radio frequency power of the main circuit module according to the target voltage.
Specifically, if the voltage of the microstrip line for the ground terminal is detected to be zero (i.e., the voltage of the terminal 3 is zero in fig. 3 to 5), it indicates that the terminal meets the design requirement of the isolation point. At this time, the target voltage obtained at the ungrounded end of the microstrip line is detected, namely, the voltage of the microstrip line for representing the radio frequency power, and then the radio frequency power of the radio frequency signal transmitted by the wire, namely, the radio frequency power of the main circuit module, can be calculated according to the target voltage and the coupling effect of the microstrip line and the wire.
Step S240, if not, adjusting the length of the microstrip line to update the voltage of the microstrip line for the grounding end to zero.
Specifically, if the voltage of the microstrip line for grounding one end is detected to be non-zero, the endpoint is not in accordance with the design requirement of the isolation point. That is, there is an error in the actual pitch of the conductor and the microstrip line at the time of production and the design pitch of the conductor and the microstrip line at the time of design. In order to improve the detection accuracy, the design requirement can be met by adjusting the length of the microstrip line, namely, the voltage of the microstrip line for the grounding end is finely adjusted by adjusting the length of the microstrip line, so that the voltage of the microstrip line for the grounding end is updated to zero, and the design requirement is met, thereby improving the detection accuracy.
After the voltage of the ground terminal of the microstrip line is updated to zero, the above step S230 may be performed to determine the rf power of the main circuit module.
It can be seen that the embodiment is applied to a detection module of a radio frequency power detection circuit, the radio frequency power detection circuit comprises a main circuit module, a microstrip line and a detection module, wherein the microstrip line and a wire in the main circuit module are arranged in parallel and coupled, and one end of the microstrip line is used for grounding. In the example of the application, the test voltage can be obtained by detecting the voltage of the microstrip line for grounding one end when the lead is electrified; determining whether the test voltage is zero; if yes, detecting a target voltage of an ungrounded end of the microstrip line, and determining radio frequency power of the main circuit module according to the target voltage; if not, the length of the microstrip line is adjusted to update the voltage of the microstrip line for the grounding end to zero. Thereby deriving the radio frequency power of the main circuit module from the target voltage. Therefore, in the application, when the voltage of the microstrip line for the grounding end is not zero, the problem caused by the difference between the actual distance between the lead and the microstrip line and the design distance can be solved by adjusting the length of the microstrip line, so that the voltage of the microstrip line for the grounding end is adjusted to zero, the radio frequency power of the main circuit module can be accurately determined by the target voltage of the ungrounded end of the microstrip line, and the accuracy of radio frequency power detection can be improved.
Referring to fig. 3 to 5, opposite ends (i.e., the terminal 1 and the terminal 2) of the conductive line 11 are used to connect the electronic components of the main circuit module, one of opposite ends (i.e., the terminal 3) of the microstrip line 20 is used to be grounded, and the other end (i.e., the terminal 4) is connected to the detection module 30. In one possible example, the microstrip line 20 includes a main line body 21 and a plurality of sub-line bodies 22, where the main line body 21 and the plurality of sub-line bodies 22 are arranged in an extending manner along the same direction, one end (i.e., an end point 3) of the main line body 21 is grounded, and the other end of the main line body 21 is detachably connected to a sub-line body 22 adjacent to the main line body 21 in the plurality of sub-line bodies 22, so as to implement on or off of the main line body 21 and a sub-line body 22 adjacent to the microstrip line 20 in the plurality of sub-line bodies 22, and the end-to-end of the plurality of sub-line bodies 22 are sequentially detachably connected so as to implement on or off of two adjacent sub-line bodies 22 in the plurality of sub-line bodies 22.
The plurality of sub-wires 22 may be arranged in equal length, or the lengths of the plurality of sub-wires 22 may be arranged differently, which is not limited herein. The number of the sub-line bodies 22 in fig. 3 to 5 is merely an example, and the specific number is not further limited. The detachable mode between the main line body 21 and the adjacent sub line bodies 22 can be realized manually or electrically.
Specifically, at the time of design, the microstrip line 20 may be designed as a detachably connected multi-stage structure to connect different numbers of sub-line bodies 22 on the main line body 21 at the time of adjusting the length of the microstrip line 20.
In a specific implementation, referring to fig. 3 to 5, the microstrip line 20 includes a main line body 21 and a plurality of sub-line bodies 22. The main wire body 21 and the plurality of sub-wire bodies 22 may be arranged to extend in the same direction so as to be arranged in parallel with the wire, thereby achieving coupling with the wire. When the length of the microstrip line 20 needs to be adjusted, at least one sub-line body 22 and the main line body 21 may be connected or disconnected according to the distance between the sub-line body 22 and the main line body 21, so as to ensure the connection between the main line body 21 and each connected sub-line body 22. After adjusting the length of the microstrip line 20, the ungrounded end of the microstrip line 20 for detecting the target voltage will be updated to the end of the sub-line body 22 connected to the main line body 21 and farthest from the main line body 21. For example, referring to fig. 3 to 5, when the main line body 21 and all the sub line bodies 22 in the drawing are connected, the point for detecting the target voltage is the end point 4.
It can be seen that, in the present example, by providing the microstrip line 20 as the main line body 21 and the plurality of sub line bodies 22 which are detachably connected, the length adjustment of the microstrip line 20 as a whole can be achieved by adjusting the number of sub line bodies 22 connected to the main line body 21, so that the convenience of the length adjustment of the microstrip line 20 can be improved while ensuring the accuracy of the radio frequency power detection.
Referring to fig. 3 and 4, in one possible example, the main wire body 21 and the plurality of sub-wire bodies 22 are provided with a communication hole 20a between adjacent two, and the rf power detection circuit further includes a connection member, and the rf power detection circuit is configured to perform on or off of the main wire body 21 and the plurality of sub-wire bodies 22 by inserting or extracting the connection member into or from the communication hole 20 a.
Wherein the communication hole 20a is used for accommodating the connector, and the communication hole 20a may be a metal hole, such as a through hole, to ensure the connection conduction reliability after the connector is inserted. The connection member may be a metal member such as a pin, so as to be fixed when the corresponding communication hole 20a is inserted, and to be connected to the main line body 21 and the sub line body 22 adjacent to each other, or to the sub line bodies 22 adjacent to each other.
In a specific implementation, in adjusting the length of the extension microstrip line 20, the connection member may be manually inserted into the corresponding communication hole 20 a. Alternatively, the connection member may be inserted into the corresponding communication hole 20a in an electronically controlled manner. For example, when the connector is a pin, the connector may be inserted into the corresponding communication hole 20a by an automatic pin inserting machine. Similarly, when adjusting the length of the microstrip line 20, the connecting piece may be pulled out of the communication hole 20a manually or electrically to disconnect the connection between the adjacent main line body 21 and the sub line body 22 or between the adjacent two sub line bodies 22.
It can be seen that, in the present example, the connection or disconnection between the main line body 21 and the adjacent two of the plurality of sub-line bodies 22 is achieved by inserting or extracting the connection member into or from the communication hole 20a, which is advantageous in improving the convenience of achieving the removability between the main line body 21 and the adjacent two of the plurality of sub-line bodies 22. Meanwhile, the connection stability between the main line body 21 and the adjacent two of the plurality of sub-line bodies 22 can be ensured during connection, thereby ensuring the application reliability of the radio frequency power detection circuit.
Alternatively, referring to fig. 5, in one possible example, any adjacent two of the main line body 21 and the plurality of sub line bodies 22 are provided with electrically controlled switches (e.g., switch K5, switch K6, switch K7) to enable on and off between the adjacent two of the main line body 21 and the plurality of sub line bodies 22 through the switches, so as to enable detachable connection through an electrically controlled manner, so as to improve the intelligence of the radio frequency power detection circuit.
Alternatively still, in one possible example, any two adjacent main wire body 21 and multiple sub wire bodies 22 are disposed at intervals, and any two adjacent two may be detachably connected by connecting wires or removing wires. In this way, it is advantageous to ensure the reliability of connection of any adjacent two of the main line body 21 and the plurality of sub line bodies 22.
In one possible example, the adjusting the length of the microstrip line includes: and sending an adjusting instruction to the test terminal, wherein the adjusting instruction is used for indicating the test terminal to display adjusting information, and the adjusting information is used for indicating a tester to connect the main line body with at least one of the plurality of sub-line bodies so as to realize the conduction of the main line body and the at least one of the plurality of sub-line bodies.
The detection module can be in communication connection with the test terminal so as to realize information transmission with the test terminal. The test terminals may be various computing devices with wireless communication capabilities or other processing devices connected to the wireless modem, as well as various forms of user equipment (UserEquipment, UE), mobile stations (MobileStation, MS), terminal devices (terminally), etc.
Specifically, the length adjustment of the microstrip line may be used in the test phase to ensure the accuracy of the radio frequency power tested during application.
In a specific implementation, the detection module detects that the voltage value of the microstrip line for the grounding end is not zero, and can send an adjusting instruction to the test terminal to instruct a tester to adjust the length of the microstrip line. The manner in which the tester adjusts the length of the microstrip line includes inserting a connector in the communication hole, or closing a switch, or connecting adjacent two of the main line body and the plurality of sub line bodies by a wire.
In particular, the adjustment information may be used only to display the adjustment requirement. At this time, the tester can connect the plurality of sub-line bodies with the main line body in sequence according to the distance between the sub-line body and the main line body until the voltage value of the microstrip line for grounding one end is adjusted to zero. For example, referring to fig. 3, after receiving the adjustment information, the tester may connect the main line body and the sub line body adjacent to the main line body. And the detection module detects the length of the microstrip line to update, then re-detects the voltage of the microstrip line for grounding one end, and if the voltage is zero, the voltage for determining the radio frequency power is obtained by detecting one end of the sub-line body, which is far away from the main line body. And if the voltage is still not zero, sending an adjusting instruction to the test terminal again. After receiving the updated adjustment information, the tester can further connect the sub-line body adjacent to the sub-line body so as to further adjust the length of the microstrip line until the design requirement is met by adjusting the length of the microstrip line.
Specifically, the adjustment information can also display the number of sub-line bodies to be adjusted, so that a tester can adjust the sub-line bodies in place once after receiving the adjustment information, and the adjustment time is shortened. Further, after the detection module detects that the length of the microstrip line is adjusted, whether the voltage of the microstrip line for grounding one end is zero can be further detected, so that the accuracy and the reliability of the length adjustment of the microstrip line are improved.
Further, referring to fig. 4 or fig. 5, the end portions of the main line body and the plurality of sub-line bodies, which are away from the main line body and are used for grounding one end, may be connected with the detection module, so as to detect the end point value of the ungrounded one end of the main line body when the main line body is not connected with the sub-line bodies, or correspondingly detect the end point value of the end portion of the corresponding sub-line body when the main line body is connected with the sub-line bodies, so as to determine the radio frequency power according to the end point value. As shown in fig. 4, switches (e.g., K1, K2, K3, K4 in fig. 4) may be further respectively disposed between the end of the main line body, where the main line body and the plurality of sub line bodies deviate from the end for grounding, and the detection module, so that when the sub line bodies are connected, the corresponding switches are closed, so as to reduce interference of data, and improve accuracy and reliability of the detected radio frequency power. For example, if the main body needs to be connected to and connected to two adjacent sub-bodies, the switch K3 needs to be closed, and the switches K1, K2, K4 are opened.
It can be seen that, in this example, by sending an adjustment instruction to the test terminal to instruct the tester to adjust the length of the microstrip line, the stability of connection between the main line body and the plurality of sub-line bodies adjacent to each other can be ensured, thereby improving the reliability of microstrip line length adjustment.
In one possible example, the radio frequency power detection circuit is provided with a first switch corresponding to a connection of the main line body and a sub line body adjacent to the microstrip line among the plurality of sub line bodies, and a second switch corresponding to a connection of every two adjacent sub line bodies among the plurality of sub line bodies, and the adjusting the length of the microstrip line includes: controlling the first switch to be closed so as to communicate the main line body and a sub-line body adjacent to the main line body; or controlling the first switch and at least one second switch to be closed so as to communicate the main line body and at least two sub-line bodies.
If the main line body and the plurality of sub-line bodies are connected with each other through the communication hole and the electrically controlled connecting piece, the first switch can be the connecting piece for being inserted into the communication hole between the main line body and the adjacent sub-line bodies. The second switch may be a connection member for inserting the communication hole between the adjacent two sub-line bodies. Alternatively, when the first switch and the second switch are in a switching structure such as a field effect transistor or a transistor, the first switch may be the switch K5 in fig. 5, and the second switch may be the switch K6 and the switch K7 in fig. 5.
Specifically, the detection module may sequentially close the first switch and the second switch according to the distance between the sub-line body and the main line body until the voltage value of the microstrip line for the grounding end is adjusted to be zero by adjusting the length of the microstrip line. For example, referring to fig. 5, the detection module may first close the first switch to connect the main line body and the sub line body adjacent to the main line body. And the detection module detects the length of the microstrip line to update, then re-detects the voltage of the microstrip line for grounding one end, and if the voltage is zero, the voltage for determining the radio frequency power is obtained by detecting one end of the sub-line body, which is far away from the main line body. If the voltage is still not zero, the second switch closest to the microstrip line is closed, so that the second sub-line is connected to adjust the length of the microstrip line. The detection module can repeat the actions, and sequentially increases the number of the accessed sub-line bodies until the voltage value of the microstrip line for the grounding end is adjusted to be zero by adjusting the length of the microstrip line.
Specifically, the detection module can also determine the number of sub-line bodies to be connected according to the detected voltage value of the microstrip line for grounding one end, so that the first switch and the second switch with the corresponding number are closed, and the time consumption for adjustment is shortened. Further, after the detection module detects that the length of the microstrip line is adjusted, whether the voltage of the microstrip line for grounding one end is zero can be further detected, so that the accuracy and the reliability of the length adjustment of the microstrip line are improved.
In this example, the connection and conduction between the main line body and the sub line body are realized by controlling the first switch and the second switch, so that the length adjustment of the microstrip line can be more intelligent, and the influence of human factors is reduced.
In one possible example, the adjusting the length of the microstrip line includes: determining a voltage difference between the test voltage and a zero voltage; determining the length of the target microstrip line according to the voltage difference value; and adjusting the length of the microstrip line according to the length of the target microstrip line.
The target microstrip line length may be the total length of the microstrip line or the length of the microstrip line to be adjusted.
Specifically, when the target microstrip line length is the total length of the microstrip line, the detection module may determine the number of sub-line bodies to be connected to the main line body according to the total length of the microstrip line, so as to acquire the current situation that the main line body is connected to the sub-line body, so as to adjust the length of the microstrip line to the target microstrip line length according to the current situation that the main line body is connected to the sub-line body. Or the length of the target microstrip line is the length of the microstrip line to be adjusted when the length of the target microstrip line is the total length of the microstrip line, and the detection module determines the sub-line body to be connected or disconnected according to the length of the sub-line body.
In a specific implementation, the detection module may invoke the correspondence between the voltage difference and the microstrip line length from a storage location (such as a memory or a database). The correspondence may be set according to an empirical value; or the corresponding relation can be calculated through the coupling effect analysis of the microstrip line and the lead, so that the accuracy and the reliability of microstrip line adjustment are improved. For example, if the storage location stores the following correspondence: the microstrip line length corresponding to the voltage difference A is a, the microstrip line length corresponding to the voltage difference B is B, and the microstrip line length corresponding to the voltage difference C is C. And if the voltage difference between the test voltage and the zero voltage is determined to be B, the target microstrip line length corresponding to the voltage difference B can be inquired and obtained to be B. And then, according to the length b of the target microstrip line, determining the number of the sub-line bodies which need to be connected with the main line body, thereby realizing accurate adjustment of the length of the microstrip line. Specifically, the correspondence between the voltage difference and the microstrip line length may be stored in a data table in a storage location, so as to facilitate data call.
It can be seen that in this example, the voltage difference between the detected test voltage and zero voltage is determined. The length of the microstrip line to be adjusted is determined, and the number of the sub-line bodies to be connected on the main line body can be determined at one time, so that the length of the microstrip line is adjusted in place at one time, the time consumption of microstrip line adjustment can be shortened, and the efficiency of radio frequency power detection can be improved.
In one possible example, after the determining the radio frequency power of the main circuit module according to the target voltage, the method further includes: acquiring a real-time environment temperature and a test environment temperature when testing the radio frequency power; comparing the real-time environment temperature with the test environment temperature to obtain a comparison result; determining whether the ambient temperature is changed according to the comparison result; if yes, the length of the microstrip line is adjusted so as to renew the voltage of the microstrip line for the grounding end to be zero again; if not, the radio frequency power detection circuit is kept to operate.
The test environment temperature is the environment temperature detected when the voltage of the grounding end of the microstrip line is regulated to zero in the test stage. The real-time ambient temperature refers to the ambient temperature detected in real-time during the run phase.
In a specific implementation, the detection module can determine the temperature difference between the real-time environment temperature and the test environment temperature when comparing the real-time environment temperature and the test environment temperature. If the temperature difference is zero, the comparison result shows that the ambient temperature is unchanged, and the radio frequency power detection circuit can still be normally used at the moment. If the temperature difference is not zero, it indicates that the ambient temperature is changed, and the length of the microstrip line can be adjusted according to the temperature difference.
Specifically, when it is determined that the temperature difference is not zero, it may be further determined whether the temperature difference reaches a preset threshold, and the length of the microstrip line is adjusted according to the temperature difference when the temperature difference reaches the preset threshold. Specifically, the storage position may also store a correspondence between the temperature difference and the microstrip line length, so as to adjust the microstrip line length according to the temperature difference in a similar manner of adjusting the microstrip line length according to the above-mentioned passing voltage difference.
Or specifically, when the temperature difference is determined to be non-zero, the detection module may acquire the voltage of the microstrip line for the grounded end, and determine whether the voltage is zero, so as to adjust the length of the microstrip line when the voltage is non-zero. In the application process of the radio frequency power detection circuit, compared with the process of acquiring and analyzing the voltage of the microstrip line for the grounding end in real time, the method can reduce the energy consumption of the radio frequency power detection circuit and reduce the data processing capacity of the detection module by acquiring the voltage of the microstrip line for the grounding end after detecting the temperature change so as to determine whether the length of the microstrip line needs to be readjusted.
It can be seen that in this example, by adjusting the length of the microstrip line by detecting a temperature change during use, the influence of the change of factors such as a filling medium, etc. on the radio frequency power detection due to the temperature change can be avoided, thereby improving the effectiveness and reliability of the radio frequency power detection for a long time.
