All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.

It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The tuning method, the tuning device, the electronic equipment and the readable storage medium provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
In some embodiments of the present application, a tuning method is provided for a radio frequency assembly, where the radio frequency assembly includes a power amplifier and a tuning assembly, the tuning assembly includes a first state and a second state, where a load impedance of the power amplifier is a first impedance when the tuning assembly is in the first state, and where the load impedance of the power amplifier is a second impedance when the tuning assembly is in the second state, the second impedance being greater than the first impedance;
fig. 1 shows a flowchart of a tuning method according to an embodiment of the present application, and as shown in fig. 1, the tuning method includes:
Step 102, under the condition that the first output power of the radio frequency component is in a first power range, controlling the adjusting component to be switched into a second state;
Step 104, under the condition that the adjusting component is in the second state, the working parameters of the radio frequency component are adjusted and measured.
In the embodiment of the application, the radio frequency component can be an antenna component of mobile communication equipment such as a mobile phone and the like, and comprises a power amplifier, particularly an envelope tracking radio frequency power amplifier ET-PA, and an adjusting component which can dynamically adjust the load impedance of the envelope tracking radio frequency power amplifier ET-PA.
Wherein when the regulation component is in the first state, the load impedance of the envelope tracking radio frequency power amplifier ET-PA is a first impedance, which may be a 50 ohm impedance. When the regulating component is in the second state, the load impedance of the envelope tracking radio frequency power amplifier ET-PA is a second impedance, which is larger than the first impedance, and the second impedance may be, for example, 100 ohms, 150 ohms, 200 ohms, 300 ohms, or the like.
In particular, the reason why the overall efficiency of the radio frequency component to which the ET-PA is applied is reduced in the middle power output scenario is that the power supply modulator of the ET-PA is reduced in efficiency. The efficiency of the power modulator of the power amplifier is in a direct proportion relation with the output collector voltage Vcc, so that the efficiency of the ET power modulator can be ensured as long as the power supply requirement of the power amplifier for high collector voltage Vcc can be maintained. In the mid-power mode, the high collector voltage Vcc of the power amplifier may in turn cause deterioration of the back-off efficiency of the power amplifier.
The rollback efficiency is determined as follows:
Where η ET-PAM is the back-off efficiency of the power amplifier, I RF is the radio frequency output current, V RF is the radio frequency output voltage, I CC is the supply current of the ET power modulator to the power amplifier, and V CC is the supply voltage of the ET power modulator to the power amplifier.
Wherein, In relation to the process and static operating point of the device of the power amplifier, it is constant in a fixed operating mode, so increasing the back-off efficiency is essentially increasing V RF.
The power formula of the radio frequency component is as follows:
Where P RF is the radio frequency power, V RF is the radio frequency output voltage, and R 0 is the load impedance of the power amplifier.
As can be seen from the above formula, under the condition that the radio frequency power P RF is fixed, increasing the load impedance R 0 of the power amplifier can effectively increase V RF, thereby increasing the back-off efficiency of the power amplifier.
Therefore, the embodiment of the application adjusts the load impedance of the power amplifier by changing the state of the adjusting component, when the radio frequency component operates in a high output power state, the adjusting component is in the first state, and the load impedance of the power amplifier is the first impedance, such as 50 ohms.
When the radio frequency component is operated in a state of outputting power, the regulating component is switched to a second state, and the load impedance of the power amplifier is raised to a second impedance, such as 100 ohms, 150 ohms, 200 ohms or 300 ohms.
When the mobile communication equipment works, the working parameters of the radio frequency component need to be adjusted and measured at the first power-on, so the application aims at the output power scene of the radio frequency component to control and adjust the switching state of the component in a targeted way.
Specifically, when the mobile communication device is powered on for the first time or receives the modulation signal, the output power scene of the radio frequency component is judged first. If the first output power of the radio frequency component is in the first power range, such as the range of 10dBm to 18dBm, the radio frequency component is determined to be in a medium power output scene, and the control adjusting component is controlled to be in a second state, wherein the load impedance of the power amplifier is a high-impedance second impedance.
In this state, the working parameters of the radio frequency component are adjusted and measured, so that the matching of the working parameters with the power scene of the radio frequency component and the load impedance of the power amplifier is ensured, and the requirements of the ET radio frequency performance and the power consumption performance of the whole system are met.
According to the embodiment of the application, the load impedance of the ET-PA is changed by setting the adjusting component, when the radio frequency component operates at medium and low output power, the state of the adjusting component is changed to raise the load impedance of the ET-PA, so that the conversion efficiency of the ET-PA can be effectively improved, and meanwhile, the efficiency of an ET power supply modulator and the back-off efficiency of the PA are improved, thereby expanding the application of an ET-PA system in a medium power scene and being beneficial to improving the communication endurance of mobile communication equipment.

In the embodiment of the application, if the first output power of the radio frequency component is in the second power range, the power scene of the radio frequency component is determined to be a high power scene, and the performance of the ET-PA is in a high performance interval in the high power scene, so that the load impedance of the power amplifier does not need to be increased.
At this time, the adjusting component is controlled to switch to the first state, at this time, the load impedance of the power amplifier is the first impedance of the conventional impedance, for example, 50 ohms, and when the load impedance of the power amplifier is in the first impedance, the working parameter of the radio frequency component is adjusted and measured, so as to ensure that the working parameter is matched with the power scene of the radio frequency component and the load impedance of the power amplifier, thereby meeting the requirements of the ET radio frequency performance and the power consumption performance of the whole system.
The first power range is a power range corresponding to a high power scene of the radio frequency component, and specifically, the first power range is 10dBm to 18dBm. The second power range is a power range corresponding to a mid-power scenario of the radio frequency component, specifically the second power range is greater than or equal to 18dBm, and in some embodiments, the second power range may be set to greater than or equal to 18dBm and less than or equal to 26dBm.
According to the embodiment of the application, the load impedance of the power amplifier is adjusted according to the output power scene of the radio frequency component, and the working parameters of the radio frequency component in the corresponding output power scene are adjusted, so that the ET radio frequency performance and power consumption performance requirements are met.

Specifically, when the first adjustment is performed, the power scenario of the radio frequency component is determined, and when the first output power of the radio frequency component is in the first range, that is, in the middle power scenario, the state of the adjustment component is set to be the second state2, the adjustment state is Load Tunner State0, and at this time, the load impedance of the power amplifier is in the high impedance state, that is, the second impedance.
When the first output power of the radio frequency component is in the second range, that is, in a high power scenario, the state of the adjusting component is set to be the first state1, the adjusting state is Load Tunner State1, and the load impedance of the power amplifier is the first impedance, for example, 50 ohms.

When the first output power of the radio frequency component is in the second range, the state of the adjusting component is set to be a first state1, and the adjusting state is Load Tunner State.
By adjusting and measuring the working parameters of the radio frequency component according to the power scene of the radio frequency component, the requirements of the radio frequency performance and the power consumption performance of the radio frequency component ET can be met, and the energy consumption efficiency of the mobile communication equipment applying the radio frequency component is improved.

If the first parameter and the second parameter do not meet the required ET radio frequency performance or power consumption performance, the adjusting component can be adjusted, so that the magnitude of the second impedance is changed when the adjusting component is in the second state, and the steps of the first adjusting and the second adjusting are repeated.
