The debugging method, the debugging apparatus, the electronic device, and the readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.
In some embodiments of the present application, a tuning method is provided for a radio frequency component, where the radio frequency component includes a power amplifier and a tuning component, the tuning component includes a first state and a second state, where a load impedance of the power amplifier is a first impedance when the tuning component is in the first state, and where the tuning component is in the second state, a load impedance of the power amplifier is a second impedance, and the second impedance is greater than the first impedance;
fig. 1 shows a flowchart of a debugging method according to an embodiment of the present application, and as shown in fig. 1, the debugging method includes:
and 104, under the condition that the adjusting assembly is in the second state, adjusting and measuring the working parameters of the radio frequency assembly.
In this embodiment, the radio frequency component may specifically be an antenna component of a mobile communication device such as a mobile phone, where the radio frequency component includes a power amplifier, specifically, an envelope tracking radio frequency power amplifier ET-PA, and further includes an adjusting component, and the adjusting component is capable of dynamically adjusting a load impedance of the envelope tracking radio frequency power amplifier ET-PA.
Wherein, when the adjusting 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 an impedance of 50 ohms. When the adjusting 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 greater than the first impedance, and the second impedance may be, for example, 100 ohms, 150 ohms, 200 ohms, or 300 ohms.
In particular, in a medium power output scene, the radio frequency component applying the ET-PA has reduced overall efficiency due to the reduced efficiency of the power modulator of the ET-PA. The efficiency of the power supply modulator of the power amplifier is in direct proportion to the output collector voltage Vcc, so that the efficiency of the ET power supply modulator can be ensured as long as the power supply requirement of the power amplifier on the high collector voltage Vcc can be maintained. In the medium power mode, the high collector voltage Vcc of the power amplifier will cause the deterioration of the back-off efficiency of the power amplifier.
The determination formula of the rollback efficiency is as follows:
wherein eta is ET-PAM Is the back-off efficiency of the power amplifier, I RF Is a radio frequency output current, V RF Is a radio frequency output voltage, I CC Supply current, V, supplied to the power amplifier by the ET power modulator CC Is the supply voltage supplied by the ET supply modulator to the power amplifier.
Wherein,
in relation to the process and quiescent operating point of the devices of the power amplifier, which are constant in a fixed operating mode, the increase in back-off efficiency is therefore substantially an increase in V RF 。
The power formula of the radio frequency components is as follows:
wherein, P RF Is radio frequency power, V RF Is the radio frequency output voltage, R 0 Is the load impedance of the power amplifier.
From the above formula, at the radio frequency power P RF Under the fixed condition, the load impedance R of the power amplifier is increased 0 Can effectively lift V RF And thus increased back-off efficiency of the power amplifier.
Therefore, the present embodiment adjusts the load impedance of the power amplifier by changing the state of the adjusting component, and when the radio frequency component operates in a high output power state, the adjusting component is in a first state, where the load impedance of the power amplifier is a first impedance, such as 50 ohms.
When the radio frequency component operates in the medium output power state, the adjusting component is switched to a second state, where the load impedance of the power amplifier is raised to a second impedance, such as 100 ohms, 150 ohms, 200 ohms, or 300 ohms.
