[0030] The following describes in detail the debugging method, debugging device, electronic device and readable storage medium provided in the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] In some embodiments of the present application, a debugging method is provided for a radio frequency component, the radio frequency component includes a power amplifier and an adjustment component, the adjustment component includes a first state and a second state, when the adjustment component is in the first state, the load impedance of the power amplifier is the first impedance, when the adjustment component is in the second state, the load impedance of the power amplifier is the second impedance, and the second impedance is greater than the first impedance;

[0032] Figure 1 A flow chart of a debugging method according to an embodiment of the present application is shown. Figure 1 As shown, the debugging method includes:

[0033] Step 102, when the first output power of the radio frequency component is within the first power range, controlling the regulating component to switch to the second state;

[0034] Step 104: When the adjustment component is in the second state, the operating parameters of the radio frequency component are adjusted.

[0035] In an embodiment of the present application, the RF component can specifically be an antenna component of a mobile communication device such as a mobile phone. The RF component includes a power amplifier, specifically an envelope tracking RF power amplifier ET-PA, and also includes an adjustment component that can dynamically adjust the load impedance of the envelope tracking RF power amplifier ET-PA.

[0036] Wherein, when the adjustment component is in the first state, the load impedance of the envelope tracking RF power amplifier ET-PA is a first impedance, and the first impedance may be an impedance of 50 ohms. When the adjustment component is in the second state, the load impedance of the envelope tracking RF power amplifier ET-PA is a second impedance, and the second impedance is greater than the first impedance, and the second impedance may be, for example, 100 ohms, 150 ohms, 200 ohms, or 300 ohms.

[0037] Specifically, the reason why the overall efficiency of the RF components using ET-PA is reduced in the medium power output scenario is that the efficiency of the ET-PA power modulator decreases. The power modulator efficiency of the power amplifier is proportional to the output collector voltage Vcc, so as long as the power supply demand of the power amplifier with a high collector voltage Vcc can be maintained, the efficiency of the ET power modulator can be guaranteed. In the medium power mode, the high collector voltage Vcc of the power amplifier will lead to the deterioration of the back-off efficiency of the power amplifier.

[0038] The formula for determining the fallback efficiency is as follows:

[0039]

[0040] Among them, η ET-PAM is the back-off efficiency of the power amplifier, I RFis the RF output current, V RF is the RF output voltage, I CC is the supply current supplied by the ET power modulator to the power amplifier, V CC It is the supply voltage supplied by the ET power modulator to the power amplifier.

[0041] in, It is related to the process and static operating point of the power amplifier device. It is a fixed value in a fixed operating mode. Therefore, increasing the back-off efficiency is essentially to increase V RF .

[0042] The power formula of RF components is as follows:

[0043]

[0044] Among them, P RF is the RF power, V RF is the RF output voltage, and R0 is the load impedance of the power amplifier.

[0045] From the above formula, we can know that at the RF power P RF When the load impedance R0 of the power amplifier is fixed, increasing the V RF , thereby increasing the back-off efficiency of the power amplifier.

[0046] Therefore, the embodiment of the present application adjusts the load impedance of the power amplifier by changing the state of the adjustment component. When the RF component operates in a high output power state, the adjustment component is in a first state, and the load impedance of the power amplifier is the first impedance, such as 50 ohms.

[0047] When the RF component operates in a medium output power state, the regulating component is switched to a second state, and the load impedance of the power amplifier is increased to a second impedance, such as 100 ohms, 150 ohms, 200 ohms or 300 ohms.

[0048] When the mobile communication device is working, it is necessary to adjust the working parameters of the RF component when it is powered on for the first time. Therefore, the present application specifically controls the switching state of the adjustment component according to the output power scenario of the RF component.

[0049] Specifically, when the mobile communication device is powered on for the first time, or when a commissioning signal is received, the output power scenario of the RF component is first determined. If the first output power of the RF component is within a first power range, such as within a range of 10 dBm to 18 dBm, it is determined that the RF component is in a medium power output scenario, and the control adjustment component is in a second state, at which time the load impedance of the power amplifier is a second impedance of high impedance.

[0050] In this state, the operating parameters of the RF components are adjusted to ensure that the operating parameters match the power scenario of the RF components and the load impedance of the power amplifier, thereby meeting the requirements of the ET RF performance and the power consumption performance of the overall system.

[0051] The embodiment of the present application changes the load impedance of the ET-PA by setting an adjustment component. When the RF component operates at medium and low output power, the load impedance of the ET-PA is increased by changing the state of the adjustment component, which can effectively improve the conversion efficiency of the ET-PA, while improving the efficiency of the ET power modulator and the PA back-off efficiency, thereby expanding the application of the ET-PA system in medium-power scenarios, which is beneficial to improving the communication endurance of mobile communication equipment.

[0052] In some embodiments of the present application, the debugging method further includes:

[0053] When the first output power is within the second power range, the control regulating component is switched to the first state;

[0054] When the adjustment component is in the first state, adjusting the working parameters of the radio frequency component;

[0055] The first power range is greater than or equal to 10 dBm and less than 18 dBm; the second power range is greater than or equal to 18 dBm.

[0056] In an embodiment of the present application, if the first output power of the RF component is within the second power range, the power scenario of the RF component is determined to be a high-power scenario. In the high-power scenario, the performance of the ET-PA is in a high-performance range, so there is no need to increase the load impedance of the power amplifier.

[0057] At this time, the control adjustment component switches to the first state. At this time, the load impedance of the power amplifier is the first impedance of the conventional impedance, such as 50 ohms. When the load impedance of the power amplifier is at the first impedance, the working parameters of the RF component are adjusted to ensure that the working parameters match the power scenario of the RF component and the load impedance of the power amplifier, thereby meeting the requirements of the ET RF performance and the power consumption performance of the overall system.

[0058] The first power range is the power range corresponding to the high power scenario of the RF component, specifically, the first power range is 10dBm to 18dBm. The second power range is the power range corresponding to the medium power scenario of the RF component, specifically, the second power range is greater than or equal to 18dBm. In some embodiments, the second power range can be set to be greater than or equal to 18dBm and less than or equal to 26dBm.

[0059] The embodiment of the present application adjusts the load impedance of the power amplifier according to the output power scenario of the RF component, and adjusts the working parameters of the RF component in the corresponding output power scenario, thereby meeting the ET RF performance and power consumption performance requirements.

[0060] In some embodiments of the present application, the operating parameters of the radio frequency component are adjusted, including:

[0061] Performing a first adjustment on the power amplifier to obtain a first parameter corresponding to the first output power, the first parameter including: a delay parameter, an input power of the power amplifier, a second output power of the power amplifier, and a gain compression parameter;

[0062] A second adjustment is performed on the power amplifier to obtain a second parameter corresponding to the first parameter, and the second parameter is used to calibrate the first parameter.

[0063] In the embodiment of the present application, the first tuning is specifically ET CHAR Tunning, and ET CHAR Tunning is specifically a tuning step for determining the ET CHAR parameter within the corresponding power range, that is, the first parameter. Among them, the first parameter is specifically a static parameter, and the first parameter (ET CHAR parameter) specifically includes a delay parameter (Delay), an input power and a second output power (Pin Pout) of the power amplifier, and a gain compression parameter (Gain Compress).

[0064] The second tuning is specifically ET CAL Tunning. ET CAL Tunning is specifically a parameter for dynamically calibrating the device error of the RF component within the corresponding power range, that is, the second parameter is determined to perform a tuning step. The second parameter can correct the first parameter according to the device error during the operation of the RF component to eliminate the impact of the error.

[0065] Specifically, when performing the first adjustment, the power scenario of the RF component is determined. When the first output power of the RF component is in the first range, that is, the medium power scenario, the state of the adjustment component is set to the second state state2, and the adjustment state is Load Tunner State0. At this time, the load impedance of the power amplifier is in a high impedance state, that is, the second impedance.

[0066] When the first output power of the RF component is in the second range, that is, in a high power scenario, the state of the adjustment component is set to the first state state1, and the tuning state is Load Tunner State1. At this time, the load impedance of the power amplifier is the first impedance, such as 50 ohms.

[0067] When performing the second tuning, similarly, when the first output power of the RF component is within the first range, the state of the adjustment component is set to the second state state2, and the tuning state is Load Tunner State0. When the first output power of the RF component is within the second range, the state of the adjustment component is set to the first state state1, and the tuning state is Load Tunner State1.

[0068] By adjusting the working parameters of the RF component according to the power scenario of the RF component, the ET RF performance and power consumption performance requirements of the RF component can be met, and the energy efficiency of the mobile communication device using the RF component can be improved.

[0069] In some embodiments of the present application, after adjusting the working parameters of the radio frequency component, the adjustment method further includes:

[0070] The radio frequency performance and power consumption performance of the radio frequency component are verified according to the first parameter and the second parameter.

[0071] In an embodiment of the present application, after adjusting and obtaining the first parameter of the static parameter and the second parameter of the dynamic calibration parameter, the system verifies the ET RF performance and power consumption performance of the RF component when operating according to the first parameter and the second parameter under the corresponding power scenario.

[0072] If the first parameter and the second parameter do not meet the required ET RF performance or power consumption performance, the adjustment component can be adjusted to change the size of the second impedance when the adjustment component is in the second state, and the first adjustment and second adjustment steps can be repeated.

[0073] If the first parameter and the second parameter meet the requirements of the ET radio frequency performance or power consumption performance, the radio frequency component of the mobile communication device is controlled to operate according to the first parameter and the second parameter.

[0074] The embodiment of the present application adjusts the load impedance of the power amplifier through an adjustment component according to the first output power of the RF component, and adjusts the first parameter and the second parameter of the RF component during operation according to the adjusted load impedance for the first output power, thereby improving the ET RF performance and power consumption performance of the RF component.

[0075] The debugging method provided in the embodiment of the present application can be executed by a debugging device. In the embodiment of the present application, a method for debugging performed by a debugging device is taken as an example to illustrate the debugging device provided in the embodiment of the present application.

[0097] In some embodiments of the present application, Figure 4 A structural block diagram of a radio frequency component according to an embodiment of the present application is shown. Figure 4 As shown, the electronic device 300 further includes:

[0098] The radio frequency component 306 includes:

[0099] Power amplifier 308;

[0100] An adjustment component 310, the adjustment component 310 includes a first state and a second state;

[0101] When the regulating component 310 is in the first state, the load impedance of the power amplifier 308 is the first impedance. When the regulating component 310 is in the second state, the load impedance of the power amplifier 308 is the second impedance, which is greater than the first impedance.

[0102] The RF component 306 can specifically be an antenna component of a mobile communication device such as a mobile phone. The RF component 306 includes a power amplifier 308, specifically an envelope tracking RF power amplifier ET-PA, and also includes an adjustment component 310, which can dynamically adjust the load impedance of the envelope tracking RF power amplifier ET-PA.

[0103] When the adjustment component 310 is in the first state, the load impedance of the envelope tracking RF power amplifier ET-PA is a first impedance, which may be an impedance of 50 ohms. When the adjustment component 310 is in the second state, the load impedance of the envelope tracking RF power amplifier ET-PA is a second impedance, which is greater than the first impedance, and the second impedance may be, for example, 100 ohms, 150 ohms, 200 ohms, or 300 ohms.

[0104] The load impedance of the power amplifier 308 is adjusted by changing the state of the adjustment component 310. When the RF component 306 operates in a high output power state, the adjustment component 310 is in a first state, and the load impedance of the power amplifier 308 is a first impedance, such as 50 ohms.

[0105] When the RF component 306 operates in the medium output power state, the regulating component 310 is switched to the second state. At this time, the load impedance of the power amplifier 308 is increased to a second impedance, such as 100 ohms, 150 ohms, 200 ohms or 300 ohms.

[0106] In the embodiment of the present application, the load impedance of the ET-PA is changed by setting the adjustment component 310. When the RF component 306 operates at medium or low output power, the load impedance of the ET-PA is increased by changing the state of the adjustment component 310, which can effectively improve the conversion efficiency of the ET-PA, and at the same time improve the efficiency of the ET power modulator and the PA back-off efficiency, thereby expanding the application of the ET-PA system in medium-power scenarios, which is beneficial to improving the communication endurance of mobile communication equipment.

[0107] In some embodiments of the present application, Figure 5 One of the circuit diagrams of the radio frequency component according to the embodiment of the present application is shown, as shown in FIG. Figure 5 As shown, the RF component 306 also includes:

[0108] Antenna unit 3062;

[0109] Modem 3064;

[0110] Double-pole double-throw switch 3066 , the modem 3064 is connected to the antenna unit 3062 via the double-pole double-throw switch 3066 , and the adjustment component 310 is arranged between the double-pole double-throw switch 3066 and the modem 3064 .

[0111] In the embodiment of the present application, the adjustment component 310 is specifically a passive load tuning structure, and the adjustment component 310 can realize a reconfigurable impedance characteristic for the load of the power amplifier 308 .

[0112] Exemplarily, the regulating component 310 may include a switch component, a bypass circuit and an impedance circuit, wherein a resistor is connected in series in the impedance circuit. When the regulating component is in a first state, the switch component is connected to the bypass circuit, and the impedance of the power amplifier 308 is a first impedance, such as 50 ohms. When the regulating component is in a second state, the switch component is connected to the impedance circuit, thereby increasing the load impedance of the power amplifier 308.

[0113] This application uses a passive load tuning structure to increase the PA load impedance to high impedance in medium output power scenarios, while improving the ET power modulator efficiency and PA back-off efficiency, expanding the application of the ET-PA system in medium power scenarios and improving the battery life experience of mobile communication devices.

[0114] In some embodiments of the present application, Figure 6 FIG2 shows a second circuit diagram of a radio frequency component according to an embodiment of the present application. Figure 7 A system schematic diagram of a power amplifier circuit according to an embodiment of the present application is shown. Figure 6 and Figure 7 As shown, the power amplifier 308 includes a first power amplifier 3082 and a second power amplifier 3084;

[0115] The RF component 306 also includes:

[0116] Antenna unit 3062;

[0117] Modem 3064;

[0118] A single-pole double-throw switch 3068, wherein the modem 3064 is connected to the antenna unit 3062 via the single-pole double-throw switch 3068, and the adjustment component is disposed between the single-pole double-throw switch 3068 and the antenna unit 3062;

[0119] When the regulating component 310 is in the first state, the second power amplifier 3084 is in the on state, and when the regulating component 310 is in the second state, the second power amplifier 3084 is in the off state.

[0120] In the embodiment of the present application, the power amplifier 308 supports dual transmission, and specifically includes a first power amplifier 3082 and a second power amplifier 3084. In a single transmission scenario, the first power amplifier 3082 is a main power amplifier, and the second power amplifier does not perform transmission work at this time.

[0121] The load impedance control of the power amplifier 308 is performed using auxiliary active devices, such as Figure 6As shown, when the second power amplifier 3084 is in the on state, the load impedance of the first power amplifier 3082 is the first impedance, and when the second power amplifier 3084 is in the off state, the load impedance of the first power amplifier 3082 is the second impedance.

[0122] like Figure 7 As shown, when the second power amplifier 3084 is in the on state, Zp can present a high impedance after passing through the Impedance Inverter. At this time, Zc can present the required second impedance after combining Zp, Global Matching and Impedance Inverter.

[0123] When the second power amplifier 3084 is in the off state, Zp will present a characteristic impedance first impedance after passing through the Impedance Inverter. At this time, Zc combined with Zp, Global Matching and Impedance Inverter will present the first impedance.

[0124] The present application dynamically adjusts the load impedance of the first power amplifier 3082 by multiplexing the second power amplifier 3084 when multiplexing in a single PA output scenario. Specifically, the common end impedance of the first power amplifier 3082 is pulled to a high impedance state by the load of the second power amplifier 3084, thereby increasing the load impedance of the power amplifier 308.
