[0070] In the prior art, external instruments such as vector network analyzers and comprehensive testers are usually used for RF debugging. Specifically, after the parameters of the vector network analyzer and the comprehensive tester are set, they are connected to the device under test for testing, and then the test results are analyzed, debugged and optimized, and the process is repeated until the debugging is completed.

[0071] However, this RF debugging process requires parameter setting of the instrument during each debugging process. The debugging steps are cumbersome and time-consuming, and there is a problem of low debugging efficiency.

[0072] Based on the above problems, an embodiment of the present application proposes a performance determination method, which obtains a target frequency band to be tested, and controls at least one first target device and at least one second target device in the device to be tested to be turned on according to the target frequency band to be tested and a pre-stored mapping relationship between the target frequency band to be tested and each device in the device to be tested, thereby sending a test signal, so that the test signal passes through each first target device and each second target device in turn, and the output power of the output signal of each first target device and each second target device is obtained, so that the loss test result of the device to be tested in the target frequency band to be tested can be determined according to the isolation of each first target device, the output power of the output signal of each first target device, the coupling degree of each second target device, and the output power of the output signal of each second target device. The loss test result of the device to be tested in the target frequency band to be tested can be directly obtained by calculation, without the need to use an instrument to perform a complete performance test, avoiding the cumbersome debugging steps caused by setting parameters of the instrument, saving manpower and material resources, and improving debugging efficiency.

[0073] It can be understood that during the RF debugging process, the performance determination method provided in the embodiment of the present application can be used to obtain the loss test results of the device under test in the target test frequency band, and based on the loss test results of the device under test in the target test frequency band, it is determined whether to perform matching adjustments on the RF module, thereby achieving RF debugging of the RF module.

[0074] First, an illustrative description is given of the radio frequency module involved in the performance determination method provided in the embodiment of the present application.

[0075] RF module refers to an independent modular device that integrates RF front-end circuits, modems, antenna interfaces and other functions, and is mainly used to process the transmission and reception of radio frequency signals. RF modules usually include RF transceivers, power amplifiers, filters, mixers, frequency synthesizers and other components, and can achieve wireless communication in different frequency bands.

The RF module can operate in frequency division duplexing mode (FDD) and time division duplexing mode (TDD), realizing the reception, transmission, and processing of RF signals.

[0077] It can be understood that the structure in the RF module can be adjusted according to the actual application situation. This application only takes the RF module including a transceiver, a power amplifier, a duplexer, a transmit and receive switch, a filter, a switch and a coupler as an example for explanation.

[0078] The performance determination method provided in the embodiments of the present application is described in detail below in combination with multiple embodiments.

[0080] S201: Obtain a target frequency band to be measured.

[0081] Optionally, the target frequency band to be tested of the RF module may be acquired first, wherein the target frequency band to be tested is used to indicate the working mode of the RF module and the devices working in the RF module in this mode when determining the loss of the RF module.

[0082] Exemplarily, the target frequency band to be measured may be frequency band 1.

[0083] S202 . Control at least one first target device and at least one second target device in the device under test to be turned on according to the target frequency band to be tested and a pre-stored mapping relationship between the target frequency band to be tested and each device in the device under test.

[0084] Optionally, after obtaining the target frequency band to be tested, the devices working in the device to be tested are different under different frequency bands to be tested. Therefore, according to the target frequency band to be tested and the pre-stored mapping relationship between the target frequency band to be tested and the devices in the device to be tested, the devices in the device to be tested that work under the target frequency band to be tested can be determined, and the working devices can be controlled to be turned on.

[0085] The first target device and the second target device are both devices operating in the target frequency band to be tested. The first target device may be a device that affects the degree of signal isolation in the radio frequency module, and the second target device may be a device that affects the energy transmission ratio in the radio frequency module.

[0086] For example, continue to refer to Figure 1 As shown, when the target frequency band to be measured is frequency band 1, the first target device may be a duplexer and a switch, and the second target device may be a coupler.

[0087] S203 , sending a test signal so that the test signal passes through each first target device and each second target device in sequence, and obtaining output power of output signals of each first target device and each second target device.

[0088] Optionally, after determining the first target device and the second target device, a test signal can be sent so that the test signal passes through the first target device and the second target device in sequence, thereby causing the first target device and the second target device to generate output signals, and the output power of the output signals of each first target device and each second target device is obtained.

[0089] For example, continue to refer to Figure 1 As shown, when the first target device is a duplexer and a switch, and the second target device is a coupler, the test signal passes through the duplexer, the switch, and the coupler in sequence, and the output power of the output signals of the duplexer, the switch, and the coupler is obtained.

[0090] S204, determining a loss test result of the device under test in a target test frequency band according to the isolation of each first target device, the output power of the output signal of each first target device, the coupling degree of each second target device, and the output power of the output signal of each second target device.

[0091] Optionally, after obtaining the output power of the output signals of each first target device and each second target device, the loss test result of the device under test in the target test frequency band can be calculated based on the isolation of each first target device, the output power of the output signal of each first target device, the coupling degree of each second target device, and the output power of the output signal of each second target device.

[0092] Exemplarily, the loss test result of the device under test in the target test frequency band can be calculated based on the isolation of the duplexer and the output power of the output signal, the isolation of the switch and the output power of the output signal, and the coupling of the coupler and the output power of the output signal.

[0093] In this embodiment, by acquiring the target frequency band to be tested, and according to the target frequency band to be tested and the pre-stored mapping relationship between the target frequency band to be tested and each device in the device to be tested, at least one first target device and at least one second target device in the device to be tested are controlled to be turned on, thereby sending a test signal, so that the test signal passes through each first target device and each second target device in turn, and the output power of the output signal of each first target device and each second target device is obtained, so that the loss test result of the device to be tested in the target frequency band to be tested can be determined according to the isolation of each first target device, the output power of the output signal of each first target device, the coupling degree of each second target device and the output power of the output signal of each second target device, and the loss test result of the device to be tested in the target frequency band to be tested can be directly obtained through the isolation, coupling degree and output power of the device itself, without the need to use the instrument to perform a complete performance test, avoiding the cumbersome debugging steps caused by setting the parameters of the instrument, saving manpower and material resources, and improving the debugging efficiency.

[0094] In one possible implementation, Figure 3 Another flow chart of the performance determination method provided in the embodiment of the present application is shown in FIG. Figure 3 As shown, the method also includes:

[0095] S301 : Determine whether each first target device in the device under test is faulty according to the output power of the output signal of each first target device and the historical output power of each first target device.

[0096] Optionally, the output power of the output signal of each first target device and the historical output power of each first target device may be compared to determine whether each first target device in the device under test is faulty.

[0097] Exemplarily, the output power of the output signal of each first target device can be compared with the historical output power threshold of each first target device. If the output power of the output signal of each first target device exceeds the historical output power threshold of each first target device, it is determined that each first target device in the device under test is faulty.

[0098] Exemplarily, a historical output power variance condition of each first target device can be obtained based on the historical output power of each first target device, and the output power of the output signal of each first target device can be compared with the historical output power variance condition of each first target device. If the output power of the output signal of each first target device does not meet the historical output power variance condition of each first target device, it is determined that each first target device in the device under test is faulty.

[0099] By determining whether each first target device in the device under test is faulty based on the output power of the output signal of each first target device and the historical output power of each first target device, it is possible to more accurately judge whether the current output power abnormality is a fluctuation within the normal range or a fault caused by device aging, damage, etc.

[0101] Optionally, the output power of the output signal of each second target device and the historical output power of each second target device may be compared to determine whether each second target device in the device under test is faulty.

[0102] Exemplarily, the output power of the output signal of each second target device can be compared with the historical output power threshold of each second target device. If the output power of the output signal of each second target device exceeds the historical output power threshold of each second target device, it is determined that each second target device in the device under test is faulty.

[0103] Exemplarily, a historical output power variance condition of each second target device can be obtained based on the historical output power of each second target device, and the output power of the output signal of each second target device can be compared with the historical output power variance condition of each second target device. If the output power of the output signal of each second target device does not meet the historical output power variance condition of each second target device, it is determined that each second target device in the device under test is faulty.

[0104] By determining whether each second target device in the device under test is faulty based on the output power of the output signal of each second target device and the historical output power of each second target device, it is possible to more accurately judge whether the current output power abnormality is a fluctuation within the normal range or a fault caused by device aging, damage, etc.

[0105] In one possible implementation, Figure 4 A schematic diagram of a flow chart of controlling at least one first target device and at least one second target device in a device under test to be turned on in a performance determination method provided in an embodiment of the present application, referring to Figure 4 As shown, the above S202 controls at least one first target device and at least one second target device in the device under test to be turned on according to the target frequency band to be tested and the pre-stored mapping relationship between the target frequency band to be tested and each device in the device under test, including:

[0106] S401 : Determine a plurality of to-be-selected components corresponding to the target to-be-tested frequency band according to a target to-be-tested frequency band and a pre-stored mapping relationship between the target to-be-tested frequency band and each component in the device to be tested.

[0107] Optionally, after obtaining the target frequency band to be tested, the candidate device corresponding to the target frequency band to be tested may be searched from the pre-stored mapping relationship between the target frequency band to be tested and each device in the device to be tested to obtain multiple candidate devices corresponding to the target frequency band to be tested.

[0108] For example, continue to refer to Figure 1 As shown, when the target frequency band to be tested is frequency band 2, the components to be selected can be found from the pre-stored mapping relationship between the target frequency band to be tested and each component in the device to be tested: a transmitting and receiving switch, a filter, a switch and a coupler.

[0109] S402 , determining at least one first target device and at least one second target device according to the type of each to-be-selected device, and controlling each first target device and each second target device to be turned on.

[0110] Optionally, at least one first target device and at least one second target device can be determined according to the type of each selected device, and each first target device and each second target device can be controlled to be turned on. The type of the selected device refers to whether the device under test is a device that affects the degree of signal isolation in the RF module or a device that affects the energy transmission ratio in the RF module.

[0111] For example, continue to refer to Figure 1 As shown, when the target frequency band to be measured is frequency band 2, it can be determined that the first target device is a transmitting and receiving switch, a filter and a switch, and the second target device is a coupler, and the transmitting and receiving switch, the filter, the switch and the coupler are controlled to be turned on.

[0112] It can be understood that the number of the first target device and the number of the second target device can be multiple, and the embodiment of the present application only takes one as an example.

[0113] In a possible implementation, the number of the first target devices is multiple, the number of the second target device is one, Figure 5 A schematic diagram of a flow chart for determining the loss test result of the device under test in the target frequency band to be tested in the performance determination method provided in the embodiment of the present application, referring to Figure 5 As shown, the above S204 determines the loss test result of the device under test in the target frequency band to be tested according to the isolation of each first target device, the output power of the output signal of each first target device, the coupling degree of each second target device, and the output power of the output signal of each second target device, including:

[0114] S501 : Obtain the isolation of each first target device and the output power of the output signal.

[0115] Optionally, the isolation of each first target device and the output power of the output signal are obtained.

[0120] In one possible implementation, Figure 6 A schematic diagram of a flow chart for calculating the loss test result of the device under test in the target frequency band to be tested in the performance determination method provided in the embodiment of the present application, referring to Figure 6 As shown, the above S503 calculates the loss test result of the device under test in the target frequency band to be tested according to the isolation of each first target device and the output power of the output signal and the coupling degree of the second target device and the output power of the output signal, including:

[0121] S601 : Calculate a first sum of a coupling degree of a second target device and an output power of an output signal of the second target device.
