First embodiment
Referring to Fig. 1, the matching process of radio frequency chip provided in this embodiment, includes the following steps.
Step S101 obtains the mapping relations between the classification information of radio frequency chip and radio-frequency match parameter.
The classification information of radio frequency chip can be one in the such multiple numbers of classification 1, classification 2, classification 3 ...,
Each classification information corresponds to the index of one or more radio frequency chip.This index can be set according to actual needs.
For example, each classification information is according to following index: the receiving sensitivity of such as radio frequency chip, frequency error, phase error peak
Value, phase error are effectively, radio frequency power output, modulation spectrum and switch frequency spectrum, at least one index in stray radiation carry out
Obtained from classification.
For example, classification information is obtained according to the radio frequency power output of radio frequency chip.When in view of mobile communication networking
Far and near efficiency must be controlled the transmission power of mobile station (dynamic adjusts), during with base station communication to protect
It demonstrate,proves communication quality certain between mobile station and base station and generates apparent interference without regard to other mobile stations, mainly survey
Whether the radio frequency power output of examination mobile station meets power requirement as defined in ETSI on every level-one level of power control.Example
Such as, for GSM900Mz frequency range, the error such as table 1 of each power control level corresponding nominal power and permission.
Table 1
It is, nominal power and error are obtained according to test, under the requirement for meeting specification, it is understood that there may be in table 1
The 5th grade to the 19th grade as different grades of radio frequency chip, according to this for according to classify to radio frequency chip when, both
15 classifications are segmented into, and can will be divided into a classification similar in grade, for example, by the 5th~the 10th ranking score in table 1
For classification 1, the 11st grade to the 16th grade is divided into classification 2, the 17th grade~the 19th grade is divided into classification 3 etc., in short, can
Same category is divided into so that index is located at the radio frequency chip in identical preset range.
In addition, other than only considering radio frequency power output, it is also contemplated that one in other indexs such as receiving sensitivity
It is a or multiple, for example, being classified according to two selected indexs to radio frequency chip, or according to three selected indexs pair
Radio frequency chip is classified etc..
In short, radio frequency chip can classify according to one or multiple indexs, in this way, for each radio frequency core
For piece, all there is unique classification information.
The radio frequency chip of each classification can use identical radio-frequency match parameter.In the present embodiment, radio frequency

It is mutually adapted, obtains a kind of working condition of maximum power output.For the circuit of different characteristics, matching condition is different
's.In pure resistor element circuit, when load resistance be equal to driving source internal resistance when, then output power be maximum, this working condition at
For matching, otherwise become mismatch.Such as the radio frequency chip of classification 1, all have identical impedance matching, and the radio frequency core of classification 2
Piece, it may have identical impedance matching, to form a pair between the classification information of radio frequency chip and radio-frequency match parameter
The mapping relations answered.In other embodiments, radio-frequency match parameter may also mean that the match parameter of other non-power class.
Step S102 identifies the classification information of current radio frequency chip.
Current radio frequency chip to be debugged is first tested, is then classified to some classification, that is, assign one
Classification information.For example, the nominal power and error of current radio frequency chip are 23 ± 3, correspond to classification 1, classification 1 is current radio frequency
The classification information of chip.
Step S103 is that current radio frequency chip configures radio-frequency match parameter according to mapping relations.
It in the present embodiment, can direct root since the radio frequency chip of known class 1 corresponds to one group of impedance matching
The radio frequency that current radio frequency chip should configure is obtained according to the mapping relations of classification information and classification information and radio-frequency match parameter
Match parameter, to obtain peak power output.
In other embodiments, classification 1 can also correspond to the match parameter of other properties, such as to obtain optimal signal strong
Degree etc..
In conclusion since the matching process of radio frequency chip provided in this embodiment is by classifying to radio frequency chip,
And the radio-frequency match parameter that the radio frequency chip of each classification all has the characteristic for being directed to the category and is arranged therefore can be right
Most suitable match parameter is arranged in each radio frequency chip, perform to the performance of each radio frequency chip can most preferably, reaches radio frequency
The purpose of chip performance consistency.

In the present embodiment, can be obtained by step S201~S203 radio frequency chip classification and radio-frequency match parameter it
Between mapping relations.
Specifically, in test phase, the index of a large amount of radio frequency chips is measured, for example, by changing each radio frequency chip
Output end loads to measure the index of radio frequency chip, is measured by way of load balance factor (loadpull).Then, according to
Measurement result classifies multiple radio frequency chips, and the detailed process of classification may refer to the related description in first embodiment,
Details are not described herein again.
Further, the radio frequency chip of each classification is debugged, the purpose of debugging, which may is that, keeps the radio frequency chip of the category equal
Peak power output can be obtained；Then, radio-frequency match parameter corresponding with the radio frequency chip of each classification is obtained.
It might be possible that having got in debugging and having met default capabilities level (such as peak power output)
Radio-frequency match parameter more than one set, but multiple groups, then need to select wherein one group as radio frequency corresponding with classification information
With parameter.This group of radio-frequency match parameter of selection can be in addition to output power is maximum, also take into account other factors, such as
The intensity of output signal is stronger, and transmission performance is more stable etc..Specific selection gist can be set according to actual needs.
To sum up, the matching process of radio frequency chip provided in this embodiment, by being carried out first to a large amount of radio frequency chip in advance
