[0051] In addition, the accompanying drawings are only schematic illustrations of the embodiments of the present application and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and their repeated descriptions will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0052] In a first aspect, this exemplary embodiment provides an antenna integrated T / R component testing device 100. Figures 1 to 3 As shown, including:

[0053] Base 110,

[0054] A shielding member 120, which is disposed on the base 110, and a guide groove 121 is disposed on one side of the shielding member 120, and the guide groove 121 is used to place the T / R assembly 170, and a support member 130 is connected to the groove wall of the guide groove 121, and an auxiliary test radiator 140 adapted to the T / R assembly 170 is disposed on the other side of the shielding member 120;

[0057] The embodiment of the present application provides an antenna-integrated T / R component testing device 100, by setting a guide groove 121 and a support member 130 on one side of the shielding member 120, and setting an auxiliary test radiator 140 on the other side of the shielding member 120, the guide groove 121 is used to place the T / R component radiator 172, and the indicators of the T / R component 170 are measured by the measuring component 150, and are regulated by the control component 160, thereby realizing batch testing of the T / R component 170 and improving the stability and accuracy of the test results.

[0058] In one embodiment, the antenna-integrated T / R component test device 100 simulates a small darkroom effect, that is, the shielding member 120 can preferably be a shielding box, which is a metal cavity filled with a load absorbing material (LAM), so that electromagnetic interference and spatial coupling can be shielded, the absorbing effect is improved, and the stability of the test effect is improved. The setting of the shielding member 120 can not only shield the external interference signal of the antenna-integrated T / R component test device 100, but also prevent the test signal transmitted in the antenna-integrated T / R component test device 100 from generating a "multipath effect" due to reflection.

[0059] In one embodiment, a T / R assembly 170 is designed to include a T / R assembly body 171 and a T / R assembly radiator 172 .

[0060] When testing, the T / R assembly body 171 is placed on the support 130 .

[0061] The T / R assembly radiator 172 is matched and connected with the T / R assembly body 171 . When testing, the T / R assembly radiator 172 is placed in the guide groove 121 .

[0062] Furthermore, if Figure 4 As shown, the specific structure of the support member 130 is designed. The support member 130 includes: a support plate 131, a support frame 132 and a fastener 133.

[0063] One end of the support plate 131 is connected to the groove wall of the guide groove 121 , and a T / R assembly body 171 is placed on the support plate 131 .

[0064] The support frame 132 is disposed below the support plate 131 , one end of the support frame 132 is fastened to the shielding member 120 , and the other end of the support frame 132 is fastened to the support plate 131 .

[0065] The fastener 133 is disposed on the support plate 131 , and is used to lock and fix the T / R assembly 170 during testing.

[0069] A through hole is provided on the support plate 131 , so that the vertical block 1333 passes through the through hole, and the two exposed ends are respectively connected to the first horizontal block 1332 provided on the upper surface of the support plate 131 and the second horizontal block 1334 provided on the lower surface of the support plate 131 .

[0073] The auxiliary test radiator 140 is the same as the T / R component radiator 172, and its external part is led out by an SMA connector, which can simulate the electromagnetic environment inside the antenna integrated T / R component test device 100. Through the electromagnetic simulation experiment, the optimal relative distance between the auxiliary test radiator 140 and the T / R component radiator 172 can be determined, so that the loss of the electromagnetic signal in the antenna integrated T / R component test device 100 can be reduced, making the test results more accurate and improving the accuracy of the test results. The electromagnetic loss of the antenna integrated T / R component test device 100 within the working frequency band of the T / R component 170 is controlled within 15dB, that is, not more than 15dB.

[0075] The display control component 162 in this embodiment can provide control codes and generate control signals required by the T / R component 170. The T / R component 170 switches the transceiver state of the work in turn, and transmits the electromagnetic signal to the measuring component 150 through the antenna integrated T / R component testing device 100. After the measuring component 150 calibrates the loss value of the electromagnetic signal of the antenna integrated T / R component testing device 100, the collected electromagnetic signal can be displayed and stored.

[0076] In one embodiment, the measurement component 150 includes at least a vector network measuring instrument and a switch matrix; the first end of the vector network measuring instrument is connected to the T / R component 170; the second end of the vector network measuring instrument is connected to one end of the switch matrix, and the other end of the switch matrix is ​​connected to the auxiliary test radiator 140; the third end of the vector network measuring instrument is connected to the display and control computer 1621.
