Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a system for adjusting transmission power of a mobile terminal according to an embodiment of the present application. The system comprises a mobile terminal 1 and a test instrument 2, wherein the mobile terminal 1 comprises a baseband chip 11, a transceiver 12, a radio frequency amplifier 13, a coupler 14 and an antenna 15. The base band chip 11 is connected with the transceiver 12, the transceiver 12 is connected with the radio frequency amplifier 13, when the working mode of the mobile terminal 1 is a radiation mode, the radio frequency amplifier 13 is connected with the antenna 15, the coupler 14 is connected between the radio frequency amplifier 13 and the antenna 15, and the coupler 14 is also connected with the base band chip 11; when the operation mode of the mobile terminal 1 is the conduction mode, the radio frequency amplifier 13 is connected with the test instrument 2, the coupler 14 is connected between the radio frequency amplifier 13 and the test instrument 2, and the coupler 14 is further connected with the baseband chip 11.
As shown in fig. 2, fig. 2 is a schematic flowchart of a method for adjusting a transmission power of a mobile terminal according to an embodiment of the present application. The method for adjusting the transmitting power of the mobile terminal can be applied to the mobile terminal, and the specific flow of the method for adjusting the transmitting power of the mobile terminal can be as follows:
201. and acquiring the load impedance of the radio frequency amplifier.
In the embodiment of the application, when the radio frequency amplifier is connected with the antenna, the radio frequency amplifier is disconnected from the test instrument, and the antenna is used as the load of the radio frequency amplifier, that is, the load impedance of the radio frequency amplifier is the impedance of the antenna. The impedance of the antenna is not the standard 50 ohms but has a certain gap around 50 ohms from 50 ohms. As shown in fig. 3, it can be seen from the smith impedance characteristic diagram that when the rf amplifier operates in a certain frequency band, the impedance curve a of the rf amplifier is circular around the standard point O (50ohm), and is relatively divergent, i.e. has a certain distance from the standard point.
When the radio frequency amplifier is connected with the test instrument, the radio frequency amplifier is disconnected from the antenna, and the test instrument can set standard impedance, namely the impedance set by the test instrument is 50 ohms, namely the load impedance of the radio frequency amplifier is 50 ohms. As shown in fig. 4, it can be seen from the smith impedance characteristic diagram that when the rf amplifier operates in a certain frequency band, the load impedance curve B of the rf amplifier is tightly converged around the standard point O (50 ohm).
Therefore, when the rf amplifier is connected to an antenna or a test instrument, the load impedance of the rf amplifier is different. In addition, because the load impedance of the radio frequency amplifier when the radio frequency amplifier works in a certain frequency band is in a curve shape, and the curve cannot be directly obtained in practical application, the working frequency band of the radio frequency amplifier can be dispersed into a plurality of frequency points, and the load impedance of the radio frequency amplifier can be obtained by obtaining the load impedance of each frequency point.
Specifically, the obtaining the load impedance of the radio frequency amplifier in step 201 includes:
and acquiring the load impedance of the radio frequency amplifier at each frequency point of the working frequency band through the coupler.
It should be noted that the coupler is connected between the rf amplifier and the antenna or the test instrument, and the load impedance of the rf amplifier can be mapped to another branch through the coupler, that is, the coupler feeds back the load impedance of the rf amplifier to the baseband chip, so as to avoid impedance offset and energy loss caused by the direct connection of the baseband chip to the feeder.
202. And determining the working mode of the mobile terminal according to the load impedance of the radio frequency amplifier.
In the embodiment of the present application, since the load impedance of the rf amplifier when the rf amplifier is connected to the antenna surrounds 50 ohms and has a certain difference (larger difference) from 50 ohms, and the load impedance of the rf amplifier when the rf amplifier is connected to the testing apparatus 2 is tightly converged around 50 ohms (smaller difference), the baseband chip can preset a range to distinguish two connection modes, thereby distinguishing the working modes of the mobile terminal.
Specifically, the determining the operation mode of the mobile terminal according to the load impedance of the radio frequency amplifier in step 202 includes:
detecting whether the load impedance of the radio frequency amplifier is within a preset range;
if so, determining that the working mode of the mobile terminal is a conduction mode;
and if not, determining that the working mode of the mobile terminal is a radiation mode.
It should be noted that, if the baseband chip detects that the load impedance of the radio frequency amplifier is within the preset range, it indicates that the load impedance of the radio frequency amplifier is tightly converged around 50 ohms, the radio frequency amplifier is connected with a test instrument, and the working mode of the mobile terminal is a conduction mode; if the baseband chip detects that the load impedance of the radio frequency amplifier is outside the preset range, it indicates that the load impedance of the radio frequency amplifier has a certain difference from 50 ohms, the radio frequency amplifier is connected with the antenna, and the working mode of the mobile terminal is a radiation mode.
The load impedance includes a resistance and a reactance, the preset range may be a preset resistance range, and the baseband chip may determine whether the load impedance is within the preset range by detecting whether the resistance in the load impedance is within the preset resistance range (e.g., 50 +/-5% ohm). In addition, since the load impedance corresponds to the reflection coefficient and the VSWR (Voltage Standing Wave Ratio), the preset range may be a preset reflection coefficient range or a preset VSWR range, and the baseband chip may further determine whether the load impedance is within the preset range by detecting whether the reflection coefficient or the VSWR is within the preset reflection coefficient range or the preset VSWR range.
In addition, the load impedances of the radio frequency amplifiers at different frequency points are different, so that in order to avoid detecting the load impedance of the radio frequency amplifier at each frequency point of the working frequency band and improve the detection efficiency, the load impedance of the radio frequency amplifier at a part of frequency points of the working frequency band can be selected for detection. Meanwhile, because the load impedance curve is an arc curve, in order to avoid misjudgment caused by the fact that the load impedance of the radio frequency amplifier at a certain frequency point is just 50 ohms, the load impedance of the radio frequency amplifier at three frequency points of the working frequency band can be selected for detection.
Specifically, the detecting whether the load impedance of the radio frequency amplifier is within a preset range includes:
detecting whether load impedances of the radio frequency amplifier at three frequency points are all located in a preset range, wherein the three frequency points are a highest frequency point, a lowest frequency point and an intermediate frequency point of the working frequency band;
if yes, judging that the load impedance of the radio frequency amplifier is within a preset range;
and if not, judging that the load impedance of the radio frequency amplifier is out of a preset range.
It should be noted that the highest frequency point is a frequency point with the largest frequency in the operating frequency band, the lowest frequency point is a frequency point with the smallest frequency in the operating frequency band, and the middle frequency point is a frequency point with a middle frequency in the operating frequency band.
When the radio frequency amplifier is connected with the test instrument, the load impedance of the radio frequency amplifier at each frequency point of the working frequency range is within the preset range, so that the baseband chip can detect that the load impedance of the radio frequency amplifier at three frequency points is within the preset range, and the load impedance of the radio frequency amplifier is determined to be within the preset range. When the radio frequency amplifier is connected with the antenna, the load impedance of each frequency point of the radio frequency amplifier in the working frequency band is located outside the preset range, or only the load impedance of a specific frequency point is located within the preset range, so that the baseband chip can detect that the load impedance of the radio frequency amplifier at three frequency points is located outside the preset range, or the load impedance of a part of frequency points is located within the preset range, and the load impedance of another part of frequency points is located outside the preset range, namely the baseband chip detects that the load impedance of at least one frequency point of the radio frequency amplifier is located outside the load impedance, and thus the load impedance of the radio frequency amplifier is determined to be located outside the preset range.
203. And adjusting the transmitting power of the mobile terminal according to the working mode.
In the embodiment of the application, after the baseband chip determines the working mode of the mobile terminal, the transmitting power of the mobile terminal can be adjusted according to the requirements of different working modes.
Specifically, the adjusting the transmission power of the mobile terminal according to the working mode in step 203 specifically includes:
if the working mode of the mobile terminal is a conduction mode, adjusting the transmitting power of the mobile terminal to be low power;
and if the working mode of the mobile terminal is a radiation mode, adjusting the transmitting power of the mobile terminal to be high power.
It should be noted that, when the mobile terminal is in the conducting mode, the baseband chip needs to adjust the power parameter down to enable the rf amplifier to transmit low power, so that the rf signal indicator does not fail, i.e., the production process is not affected by the test failure, and thus the production efficiency is not affected. When the mobile terminal is in a radiation mode, the power parameter needs to be increased by the baseband chip, so that the radio frequency amplifier transmits high power, the power radiated by the radio frequency amplifier is higher than a normal value, the radiation signal intensity of the mobile terminal can be improved, and the transmission performance is enhanced.
Therefore, the method for adjusting the transmitting power of the mobile terminal can obtain the load impedance of the radio frequency amplifier, determine the working mode of the mobile terminal according to the load impedance of the radio frequency amplifier, and adjust the transmitting power of the mobile terminal according to the working mode of the mobile terminal so as to meet power requirements in different working modes, so that the intensity of a radiation signal is improved while the production efficiency is not influenced; the method can be comprehensively applied to various mobile terminals and is not limited by conduction tests.
According to the method described in the above embodiments, the present embodiment will be further described from the perspective of an adjusting device for the transmission power of a mobile terminal, which may be integrated in the mobile terminal, which may include a mobile phone, a tablet computer, and the like.
