Asking scope to be less than or equal to-36dBc, the claimed range of nonlinear indicator value ACLR UTRA2 is less than or equal to-39dBc,
The index of ACLR is relaxed 3dBc, then the index critical range of ACLR UTRA1 is less than or equal to-33dBc, ACLR UTRA2
Index critical range be less than or equal to-36dBc.Nonlinear indicator value, in index critical range, illustrates nonlinear indicator
Value difference is the most below standard, may be such that nonlinear indicator value is up to standard by the voltage value of regulation power amplifier.Non-thread
Property desired value in index critical range regulate supply voltage can not realize the up to standard of nonlinear indicator value.Therefore, according to
It is up to standard that index critical range can realize nonlinear indicator value in the way of whether accurately determining by regulation voltage value.
Step 104, regulates the voltage value of the power amplifier of described terminal mainboard.
Can describe how to regulate voltage value in detail by three embodiments.
Embodiment one, according to pre-fixed step size, regulates described voltage value successively, until described nonlinear indicator value is in institute
Till when described voltage value in the range of stating index request or after regulation is not in predetermined voltage range.
After voltage value being adjusted, if the nonlinear indicator value of terminal mainboard is in index request scope every time
In, illustrate to achieve the up to standard of nonlinear indicator value by the way of regulation voltage value, then terminate regulation, if after Tiao Jie
Voltage value, not in predetermined voltage range, illustrates nonlinear indicator value to be made to reach by the way of regulation supply voltage
Mark, then terminate regulation.It addition, voltage value is adjusted according to pre-fixed step size, can realize non-linear quickly and accurately
Desired value up to standard.
Such as, predetermined voltage range is greater than or equal to 3.8V and less than or equal to 4.2V, the power supply electricity of power amplifier
Pressure value is 4.1V, and pre-fixed step size is 0.1V, then for the first time by voltage value regulation to 4.2V, first time regulation voltage value
After, nonlinear indicator value does not has up to standard, and voltage value is regulated to 4.3V by second time, and now voltage value is not being preset
In voltage range, then terminate the regulation of voltage value.
Embodiment two, selects magnitude of voltage in multiple preset voltage value successively, and described voltage value is adjusted to choosing
The magnitude of voltage selected, until described nonlinear indicator value or has selected the plurality of predeterminated voltage in the range of described index request
Till value.
By pre-setting multiple magnitude of voltage, voltage value is adjusted by the magnitude of voltage according to pre-setting, often
Secondary voltage value is adjusted after, if the nonlinear indicator value of terminal mainboard is in the range of index request, illustrate by adjust
The mode of joint voltage value achieves the up to standard of nonlinear indicator value, then terminate regulation, if having selected multiple preset voltage value
And unrealized nonlinear indicator value is up to standard, illustrate nonlinear indicator value to be made up to standard by the way of regulation supply voltage,
Then terminate regulation.
Such as, pre-set 3 magnitudes of voltage, be V_BIAS1, V_BIAS2, V_BIAS3 respectively, for the first time by supply voltage
Value is adjusted to V_BIAS1, if nonlinear indicator value is not in the range of index request after Tiao Jie, then carries out second according to V_BIAS2
Secondary regulation, will be adjusted to V_BIAS2 by voltage value, if after Tiao Jie, nonlinear indicator value is not in the range of index request, then
Carry out third time according to V_BIAS3 to regulate, V_BIAS3 will be adjusted to by voltage value, if nonlinear indicator value is not after Tiao Jie
In the range of index request, then terminate the regulation of voltage value.
Embodiment three, selects any voltage value in multiple preset voltage value, voltage value is adjusted to any voltage
Value, if after voltage value regulation, nonlinear indicator value is not in the range of index request and in index critical range, according in advance
Fixed step size regulates voltage value successively, and such as, pre-fixed step size is 0.1, then voltage value is stepped up 0.1, if power supply
After voltage-regulation, nonlinear indicator value is not in the range of index request, and the nonlinear indicator value of relatively nearest twice, if recently
Nonlinear indicator once improves (nonlinear indicator is closer to index request scope), then continue regulation voltage value, if
The last nonlinear indicator does not improves (nonlinear indicator divergence indicator claimed range), then be gradually lowered according to pre-fixed step size
Voltage value, the most pre-fixed step size is 0.1V, if nonlinear indicator value is improved after voltage value regulation, then continues to reduce
Voltage value, if nonlinear indicator value is not improved after voltage value regulation, then terminates to regulate voltage value.
Preferably, also include: when often regulating the most described voltage value, according to the described voltage value after regulation
The transmitting power of described terminal mainboard is calibrated.
After the voltage value of power amplifier is adjusted, by the transmitting power of terminal mainboard is carried out school
Standard, it is achieved thereby that the change of the nonlinear indicator value of terminal mainboard.
Amendment V_Bias file, calibrates launching power, and the voltage value of the power amplifier of regulation could be given birth to
Effect.
Preferably, also comprising determining that the regulative mode regulating described voltage value, described regulative mode includes increasing electricity
The mode of pressure or the mode of reduction voltage, with by described regulative mode, regulate described voltage value.
Owing to the terminal mainboard of batch production produces according to reference terminal mainboard, reference terminal mainboard and batch
The Changing Pattern of the terminal mainboard produced is identical, therefore, it can the Changing Pattern according to reference terminal mainboard and determines increase
Or reduce the voltage value of power amplifier, such that it is able to rapidly adjust voltage value, and then improve regulation confession
The efficiency of piezoelectric voltage value.
Can also often regulate a voltage value and determine that next time regulates the regulative mode of supply voltage, wherein, often regulate
After supply voltage, obtain the supply voltage the first nonlinear indicator value before regulation, and supply voltage is after adjustment
Second nonlinear indicator value, the condition met according to the first nonlinear indicator value and the second nonlinear indicator value, determine power supply electricity
The regulative mode of pressure value.
Specifically, the first nonlinear indicator value and the second nonlinear indicator value are compared, if the second nonlinear indicator
Value makes moderate progress than the first nonlinear indicator value (the i.e. second nonlinear indicator is closer to index request scope), then adjust according to current
The regulative mode of joint supply voltage proceeds regulation, if the second nonlinear indicator value is not improved than the first nonlinear indicator value
(the i.e. second nonlinear indicator divergence indicator claimed range), then according to the side contrary with the regulative mode of current regulation supply voltage
Formula is adjusted.Such as, current regulative mode is the mode increasing voltage, then just adjust according to the mode reducing voltage next time
Joint.
Step 106, terminates the regulation of described voltage value.
In technique scheme, in the case of terminal mainboard occurs that when carrying out volume production nonlinear indicator value is critical, by
Voltage value in regulation power amplifier can affect nonlinear indicator value, therefore, it can by regulation power amplifier
Voltage value regulates nonlinear indicator value, so that the nonlinear indicator value of terminal mainboard is up to standard, thus improves terminal mainboard
First-pass yield and reduce false failure rate, and then improve the production efficiency of terminal, reduce the production cost of terminal.
Fig. 2 shows the flow process signal of the parameter adjusting method of terminal mainboard according to another embodiment of the invention
Figure.
As in figure 2 it is shown, the parameter adjusting method of terminal mainboard according to another embodiment of the invention, including:
Step 202, reference conditions set.
Arranging predetermined voltage range, such as, preset voltage value scope is 3.8V～4.2V, many in the range of preset voltage value
Individual V_BIAS value: 3.8V, 3.9V, 4V, 4.1V, 4.2V.The index request scope of LTE B38: the claimed range of ACLR UTRA1
The claimed range being less than or equal to-36dBc, ACLR UTRA2 is less than or equal to-39dBc, the index of ACLR is relaxed
3dBc, then the index critical range of ACLR UTRA1 is less than or equal to the index critical range of-33dBc, ACLR UTRA2 and is
Less than or equal to-36dBc.
The change of the voltage value of the power amplifier according to reference terminal (such as, surveying JINJI) is higher or inclined
Low, record offset signal frequency range nonlinear indicator value farther out and the quality of the nearer nonlinear indicator value of offset signal frequency range.
Step 204, tests nonlinear indicator value, and record.Comprehensive test instrument can be used to test nonlinear indicator value.
Step 206, it is judged that whether nonlinear indicator value is in the range of index request, when judging that nonlinear indicator value is in index
In claimed range, illustrate that this terminal mainboard is up to standard, then terminate this flow process, when judging that nonlinear indicator value is not at index request model
In enclosing, illustrate that this terminal mainboard is the most up to standard, then enter step 208 and determine whether.
Step 208, it is judged that whether nonlinear indicator value is in index critical range, critical in index in nonlinear indicator value
In the range of time, enter step 210, when nonlinear indicator value is not in index critical range, then terminate this flow process.
Such as, nonlinear indicator value ACLR1=-34dBc of the terminal mainboard of test batch production, ACLR2=-54dBc.
ACLR1 is not in the range of index request, but in index critical range.
Step 210, the voltage value of regulation PA (Power Amplifier, power amplifier).
The quiescent point of PA has voltage V_BIAS and electric current I_CQ, and general electric current Accommodation is inconspicuous.But voltage
V_BIAS is relatively big for the impact of the nonlinear indicator value of terminal mainboard, and have certain rule.
For same model mobile phone, trend has concordance.
Such as: reference terminal mainboard is set with three V_BIAS, and these three V_BIAS are respectively V_BIAS1 > V_BIAS2
>V_BIAS3。
During V_BIAS1 than V_BIAS2 time offset signal frequency range nonlinear indicator value ACLR1 farther out reduce, nearer is non-
Linear index value ACLR2 increases.
During V_BIAS3 than V_BIAS2 time offset signal frequency range nonlinear indicator value ACLR1 farther out increase, nearer is non-
Linear index value ACLR2 reduces.
This situation reason is that V_BIAS1 is on the low side, and offset signal frequency range nonlinear indicator power saturation point farther out is than deviation
The quiescent point of the nonlinear indicator that signal frequency range is nearer is more preferable.V_BIAS3 is the most contrary.
The V_BIAS of different terminals mainboard has certain deviation, a possible same type mobile phone wherein V_ than other
BIAS is little higher.This is that PA discordance causes.If the surplus of all mobile phone nonlinear indicator values is inadequate, and index
Critical, can be solved by fine setting V_BIAS.
Therefore, the Changing Pattern according to the terminal mainboard of reference terminal mainboard batch production is as follows: increase power amplifier
Voltage value in the case of, ACLR1 reduce, ACLR2 increase.The power supply of the power amplifier of this terminal mainboard can be increased
Magnitude of voltage, reduces the ACLR1 of the terminal mainboard mass-produced.
Step 212, it is judged that the power supply whether in predetermined voltage range, after judging regulation of the voltage value after regulation
When magnitude of voltage is in predetermined voltage range, entering step 214, the voltage value after judging regulation is not at predetermined voltage range
Time interior, enter step 216.
Step 214, calibrates.Specifically, one can be selected in the multiple V_BIAS values in the range of preset voltage value
Individual V_BIAS value, and calibrate launching power according to the V_BIAS value selected.Can also be according to the power amplification after regulation
The voltage value of device is calibrated launching power, and reenters step 206, it is judged that the nonlinear indicator value after change is
No up to standard.Such as, after the calibration, the ACLR1=-35.2dBc again measured, ACLR2=-52.3dBc.
Step 216, records whether PASS.Record is combined and is surveyed whether index passes through test, if by, enter next process,
If not by test, then judging that terminal mainboard is as bad plate.
Fig. 3 shows the structural representation of the parameter adjustment system of terminal mainboard according to an embodiment of the invention.
As it is shown on figure 3, the parameter adjustment system 300 of terminal mainboard according to an embodiment of the invention, including: judge

The voltage value of the power amplifier of mainboard；Described regulation unit 304 is additionally operable to, if described nonlinear indicator value is not described
In index critical range, then terminate the regulation of described voltage value.
Can describe how to regulate voltage value in detail by three embodiments.

In, illustrate to achieve the up to standard of nonlinear indicator value by the way of regulation voltage value, then terminate regulation, if after Tiao Jie
Voltage value, not in predetermined voltage range, illustrates nonlinear indicator value to be made to reach by the way of regulation supply voltage
Mark, then terminate regulation.It addition, voltage value is adjusted according to pre-fixed step size, can realize non-linear quickly and accurately
