Problems solved by technology

However, in fact, due to the hardware differences of the devices, the same set of matches has inconsistent performance on different radio frequency chips and motherboards, that is, some performances are slightly better, and some performances are slightly worse. It is impossible to make each motherboard the performance of the optimal

[0021] see figure 1 The method for matching a radio frequency chip provided in this embodiment includes the following steps.

[0022] Step S101 , acquiring a mapping relationship between category information of radio frequency chips and radio frequency matching parameters.

[0023] The category information of the radio frequency chip can be one of multiple numbers such as category 1, category 2, category 3..., and each category information corresponds to the index of one or more radio frequency chips. This indicator can be set according to actual needs. For example, each category of information is classified according to at least one of the following indicators: for example, receiving sensitivity of the radio frequency chip, frequency error, peak phase error, effective phase error, radio frequency output power, modulation spectrum and switching spectrum, and stray radiation. owned.

[0024] For example, the category information is obtained according to the radio frequency o...

[0039] see figure 2 The method for matching a radio frequency chip provided in this embodiment includes the following steps.

[0040] Step S201, measure the indexes of multiple radio frequency chips.

[0041] Step S202, classify the multiple radio frequency chips according to the measured indicators of the multiple radio frequency chips, and obtain category information.

[0042] Step S203, acquiring radio frequency matching parameters corresponding to the category information.

[0043] In this embodiment, the mapping relationship between the type of the radio frequency chip and the radio frequency matching parameter can be obtained through steps S201-S203.

[0044] Specifically, in the test phase, the indexes of a large number of radio frequency chips are measured, for example, the indexes of the radio frequency chips are measured by changing the output load of each radio frequency chip, and the measurement is performed in a load pull (load pull) manner. Then, the plurality ...

[0050] see image 3 On the basis of the second embodiment, the radio frequency chip matching method provided in this embodiment further includes step S301 of constructing a correspondence relationship database based on the correspondence relationship between indicators and category information of a plurality of radio frequency chips. For example, an index of nominal power and an error of 23±3 corresponds to category 1; an index of nominal power and an error of 5±5 corresponds to category 3, and so on.

[0051] Then, in the step of identifying the category information of the current chip, it may further include:

[0052] Step S302, measure the index of the current radio frequency chip.

[0053] Step S303, searching the corresponding relationship database for category information corresponding to the index of the current radio frequency chip.

[0054] Through the above steps, you can quickly find the category information corresponding to the indicators of the current RF chip. ...

Abstract

The invention provides a radio frequency chip matching method, comprising the following steps: obtaining a mapping relationship between the class information of the radio frequency chip and the radiofrequency matching parameters; identifying category information of the current radio frequency chip; configuring radio frequency matching parameters for the current radio frequency chip according to the mapping relationship. According to the invention, radio frequency chips are classified, and then the radio frequency matching parameters adapted to the radio frequency chips are configured for theradio frequency chips under different classifications, so that the performance of all the radio frequency chips is consistent, and the transmission performance of the mobile terminal in wireless transmission is improved.

Description

technical field [0001] The present application relates to the technical field of electronic communication, in particular to a matching method and device for a radio frequency chip. Background technique [0002] With the continuous development and wide application of electronics and communication technology, modern electronic and communication equipment is increasingly becoming an indispensable part of people's daily life. As an important part of wireless communication, radio frequency chips are widely used in mobile communication systems, broadcasting , TV, computer, remote control and many other electronic devices are getting more and more attention. [0003] The impedance matching of radio frequency chips is generally debugged during the development of mobile phone projects. After a set of matching is debugged, if the test performance can reach the basic performance, all subsequent radio frequency chips will use the same set of matching. However, in fact, due to the hardw...
