Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The embodiment of the application mainly aims at the problem that in the prior art, when the performance of the radio frequency front end of a terminal is tested by using the same antenna, the result accuracy and reliability of the radio frequency front end performance of the terminal determined by testing are low due to the fact that the performance of the antenna for testing is greatly different from the actual performance of the antenna of the terminal to be tested, and the speed measuring system for the performance of the radio frequency front end of the terminal is provided. The speed measuring system is provided with the adjusting component for performing attenuation processing on the antenna signals of all frequencies according to the antenna performance of the terminal to be tested, so that the difference between the antenna signals acquired by the radio frequency front end of the terminal and the antenna signals acquired in actual use is reduced, and the accuracy and reliability of the test result are improved.
For more clearly explaining the scheme provided by the present application, a wireless communication module of a terminal is described below with reference to fig. 1 by taking a mobile phone as an example.
Fig. 1 is a general architecture diagram of a wireless communication module of a terminal. As shown in fig. 1, the wireless communication module is composed of a chip platform, a radio frequency front end and an antenna 3.
Wherein, the chip platform includes baseband chip, radio frequency chip and power management chip etc. and the radio frequency front end includes: surface AcoustIC Wave (SAW) Filter, Duplexer (Duplexer), Low Pass Filter (LPF), Power Amplifier (PA), Switch (Switch), and the like.
The test system in the embodiment of the application is that according to the antenna performance in the wireless communication module of the terminal, the adjusting component is arranged in the radio frequency front end test system to process the antenna signal, so that the antenna signal acquired by the radio frequency front end is the same as the antenna signal acquired by the radio frequency front end in actual use during testing, and the accuracy and reliability of the test result are improved.
The following describes a method, device and system for testing a terminal radio frequency front end according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 2 is a schematic structural diagram of a terminal rf front end test system according to an embodiment of the present application.
As shown in fig. 2, the terminal rf front end test system includes: the antenna comprises an antenna body 1, a regulating component 2 and a power divider 3 which are connected in sequence.
The adjusting component 2 is used for processing antenna signals according to the antenna performance of the terminal to be tested (40, 41, 42 and 43); and each output end of the power divider 3 is respectively connected with the radio frequency front ends of the terminals to be tested 40, 41, 42 and 43.
It should be noted that the number of the terminals to be tested may be arbitrarily set according to the number of the output ends of the power divider, and in this embodiment, 4 terminals are taken as an example for schematic description.
The adjustment unit 2 is configured to process the antenna signal, and is configured to adjust insertion loss of the antenna signal, performance of each path, and the like.
Specifically, although the antenna performance of different terminals to be tested cannot be completely consistent, for the rf front end test, the difference of the antenna performance between the terminals is negligible. Therefore, in the embodiment of the present application, only the parameters of the adjusting component 2 need to be set according to the antenna performance of any one terminal to be tested, for example, the adjusting component is set according to the antenna performance of the terminal to be tested 40, so that the rf front-end performance of the terminal and the difference between the performance of the rf front-end of other terminals and the rf front-end performance of the terminal can be accurately measured.
During concrete implementation, in order to carry out complete test on the performance of the radio frequency front end of the terminal, the test system provided by the embodiment needs to accurately simulate the performance of the terminal antenna in all frequency bands during actual use, that is, the pass band width of the adjusting component 2 in the application needs to include the communication frequency band width of the terminal to be tested.
For example, if the communication frequency bandwidth of the terminal to be tested is (500 megahertz (MHz) -2.7GHz), the passband width of the adjusting component 2 includes 500MHz-2.7GHz, for example, the passband width of the adjusting component is 500MHz-2.7GHz, or 450MHz-2.71GHz, and the like, so that the performance of the radio frequency front end can be comprehensively and accurately tested by using the testing system.
The adjusting component in the terminal radio frequency front end testing system provided by the embodiment of the application can adjust the performance of each path of the antenna signal or adjust the insertion loss and the like of the antenna signal according to the antenna performance of the terminal to be tested, so that the processed antenna signal is the same as or similar to the antenna signal when the terminal actually works, and the accuracy and the reliability of the radio frequency front end testing are improved.
Furthermore, the frequency range covered by the terminal is generally wide, different frequency ranges correspond to different types of sub-antennas, and the various sub-antennas have different attenuation values due to different lines, efficiencies and insertion losses. Therefore, in this embodiment, as shown in fig. 2, the adjusting assembly 2 may be composed of N adjusting units (20, 21 … … 2N) connected in parallel, where each adjusting unit is used for performing attenuation processing on signals with different frequencies, and N is a positive integer greater than 1.
For example, if the adjusting assembly 2 includes 3 adjusting units 20, 21 and 22 connected in parallel, the communication band of the handset is (500MHz-2.7 GHz). Then, when the terminal to be tested is a mobile phone, the 3 adjusting units 20, 21, and 22 need to process signals of different frequency bands within 500MHz-2.7GHz, respectively, and then combine the processed signals of each frequency band into one path, and output the path to the terminal to be tested through the common divider, so that the signal obtained by the radio frequency front end of the terminal is the same as the antenna signal obtained by the radio frequency front end when the terminal is actually used.
Specifically, fig. 3 is a schematic structural diagram of the adjustment assembly. As shown in fig. 3, each of the adjusting units may be composed of a band pass filter (201, 211, 221, … … 2N1) and an attenuator (202, 212, 222, … … 2N2) connected in series.
It can be understood that, in the embodiment of the present application, the passband range of the bandpass filter in the ith adjusting unit is different from that of the bandpass filter in the jth adjusting unit, where i and j are positive integers greater than or equal to 1 and less than or equal to N, respectively, and i ≠ j.
That is, the band pass filters (201, 211, 221, … … 2N1) differ in the frequency of the signal allowed to pass through. For example, the frequency of the signal allowed to pass through by the band pass filter 201 is 500MHz-10KHz, the frequency of the signal allowed to pass through by the band pass filter 202 is 10KHz-100KHz, and the like, it is only necessary to ensure the sum of the frequency bands that all the band pass filters can pass through, and the communication frequency range covered by the terminal to be tested can be covered.
Furthermore, the attenuation multiples of the attenuators (202, 212, 222, … … 2N2) in each adjusting unit may be the same or different, and the attenuation of each frequency band may be set according to the actual operation of the antenna of the terminal to be tested.
It can be understood that, in the present embodiment, in the adjusting assembly 2, the greater the number of the adjusting units, the smaller the frequency range corresponding to each adjusting unit is, the higher the performance precision and accuracy of the processed antenna are, but the more complex the structure is, the higher the cost is. Therefore, during specific work, a certain number of adjusting units can be selected according to the requirements of the terminal to be tested, and then the parameters of each adjusting unit are set to meet the testing requirements.
In a preferred implementation form of the present application, in order to reduce the influence of the performance of the antenna body on the test result, the antenna body in the embodiment of the present application is as shown in fig. 4, and an omnidirectional antenna may be selected.
Fig. 4 is a terminal rf front end test system according to another embodiment of the present application.
As shown in fig. 4, the antenna body 1 in the test system is an omnidirectional antenna.
Specifically, because the omnidirectional antenna can receive signals from all angles and transmit signals to all angles, the antenna body can acquire antenna signals of all frequency bands, and complete antenna signals to be processed can be provided for the adjusting component 2, so that performance test can be performed on the radio frequency front end of the terminal in all communication frequency band ranges of the terminal.
In addition, in order to reduce the influence of the communication line on the test, in the embodiment of the present application, the antenna body 1, the adjusting component 2, and the power divider 3 may be connected through a cable 5 and a radio frequency coaxial connector 6, respectively.
The terminal radio frequency front end test system provided by the embodiment of the application, through adding the adjusting component in the test system, and the adjusting component comprises a plurality of adjusting units capable of processing the antenna signals of different frequency bands, so that the insertion loss and the access performance of the antenna signals of each frequency band can be adjusted, and the accuracy and the reliability of the radio frequency front end test are improved.
Through the analysis, the terminal radio frequency front end testing system provided by the embodiment can set the parameters of the adjusting component according to the antenna performance of the terminal to be tested in actual use, so that the antenna signal acquired by the terminal radio frequency front end is the same as the antenna signal in actual use, and the accuracy and reliability of the terminal radio frequency front end testing are improved.
During specific implementation, the parameters of the adjusting assembly can be manually tested by a tester, or in order to reduce testing errors caused by difference of manual operation and improve testing efficiency, the parameters of the adjusting assembly can also be implemented in a program control mode, and accordingly the application also provides a terminal radio frequency front end testing method.

As shown in fig. 5, the method for testing the rf front end of the terminal includes:
The terminal radio frequency front end testing method provided in this embodiment may be configured in the terminal radio frequency front end testing device provided in this embodiment, so as to configure the parameter of the adjusting component.
During specific implementation, the terminal radio frequency front-end test equipment can determine the antenna performance of the terminal to be tested in various ways. For example, according to the result of the antenna performance test system, the antenna performance of the terminal to be tested is determined; or, the antenna performance of the terminal to be tested is determined according to design parameters and the like during terminal design, which is not limited in this embodiment.
Further, it can be known from the above analysis that the antenna performance of the terminal to be tested in this embodiment refers to the antenna performance of any terminal to be tested.
Correspondingly, in a possible implementation form of the present application, during actual testing, a fixed terminal may also be used as a reference terminal, and the terminal is used as a reference for testing the radio frequency front ends of all other terminals. That is, the parameters of the adjusting component are not changed after being set according to the antenna performance of the reference terminal, and then the terminal is used as a reference when the radio frequency front end of any terminal is tested, so that the performance difference of the radio frequency front end among the terminals can be determined.
According to the terminal radio frequency front end testing method provided by the embodiment of the application, the antenna performance of the terminal to be tested is determined, and then the radio frequency front end of the terminal to be tested is tested after the parameters of the adjusting component in the testing system are configured according to the antenna performance of the terminal to be tested. Because the parameters of the adjusting component in the test system are matched with the antenna performance of the terminal, the antenna signal acquired by the radio frequency front end during the test is consistent with the antenna signal acquired during the actual work, and the accuracy and the reliability of the test result are improved.
