DETAILED DESCRIPTION

[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0024] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0025] At present, when calibrating with the radio parameter comprehensive test platform calibration device, calibration is mostly carried out channel by channel according to the parameters. This requires multiple switching of connectors and replacement of different cables during calibration, which is inefficient. Multiple switching of connectors and cables will affect their service life. There is also the risk of incorrect connection and unreliable connection, which affects the accuracy and stability of the measurement results.

[0026] Based on this, an embodiment of the utility model provides an interface adapter for a radio parameter comprehensive calibration device. When calibrating with a radio parameter comprehensive test platform calibration device, there is no need to switch channel connectors multiple times, and the output channels are not on the same side, which can prevent signal crosstalk and wrong connection, thereby improving work efficiency, and increasing the service life of connectors and cables and measurement reliability.

[0027] Specifically, see Figures 1 to 4 As shown, the interface adapter of the radio parameter comprehensive calibration device includes a cavity 1, a high-frequency input interface 4, a low-frequency input interface 3, a low-frequency output interface 5, and a high-frequency output interface 6; wherein the cavity 1 has a first outer surface 11 and a second outer surface 12 opposite to each other, the high-frequency input interface 4 and the low-frequency input interface 3 are mounted on the first outer surface 11, and the low-frequency output interface 5 and the high-frequency output interface 6 are mounted on the second outer surface 12. A first microwave electronic switch 9 and a second microwave electronic switch 10 are provided inside the cavity 1, the high-frequency input interface 4 is electrically connected to the high-frequency output interface 6 via the first microwave electronic switch 9, and the low-frequency input interface 3 is electrically connected to the low-frequency output interface 5 via the second microwave electronic switch 10.

[0028] In this embodiment, the first outer surface 11 corresponds to the end of the calibrated platform, and the second outer surface 12 corresponds to the end of the calibration device. The high-frequency input interface 4 and the low-frequency input interface 3 installed on the first outer surface 11 are used to respectively access the high-frequency signal and the low-frequency signal output by the calibrated platform through cable connection. The low-frequency output interface 5 and the high-frequency output interface 6 installed on the second outer surface 12 are used to respectively output the high-frequency signal and the low-frequency signal received by the high-frequency input interface 4 and the low-frequency input interface 3 to the calibration device through cable connection. During implementation, since the high-frequency input interface 4, the low-frequency input interface 3 and the low-frequency output interface 5, the high-frequency output interface 6 are respectively located on the first outer surface 11 and the second outer surface 12 that are opposite to each other, the user can prevent signal crosstalk and wrong connection during operation.

[0029] It should be noted that the high-frequency input interface 4, the high-frequency output interface 6, the low-frequency input interface 3, and the low-frequency output interface 5 are embedded in the outer surface of the cavity 1, and one end of the high-frequency input interface 4, the high-frequency output interface 6, the low-frequency input interface 3, and the low-frequency output interface 5 are all located inside the cavity 1. The high-frequency input interface 4 is electrically connected to the high-frequency output interface 6 via a high-frequency cable disposed inside the cavity 1, and the low-frequency input interface 3 is electrically connected to the low-frequency output interface 5 via a low-frequency cable disposed inside the cavity 1. The first microwave electronic switch 9 and the second microwave electronic switch 10 can be assembled on the high-frequency cable and the low-frequency cable, respectively. As an example only, for example, holes can be opened on the cavity 1 corresponding to the installation of the high-frequency input interface 4, the high-frequency output interface 6, the low-frequency input interface 3, and the low-frequency output interface 5, and then they can be fixed to the set positions using screws.

[0030] When the interface adapter of the radio parameter comprehensive calibration device proposed in this embodiment is applied to the calibration device of the radio parameter comprehensive test platform, and calibration is performed according to the parameters of each channel signal, the channel connectors required to be detected by the calibrated platform and the calibration device are first connected to the high-frequency input end interface 4, the low-frequency input end interface 3 and the high-frequency output end interface 6, the low-frequency output end interface 5 respectively. In actual use, it is only necessary to control the first microwave electronic switch 9 and the second microwave electronic switch 10 to realize the conversion of the channel signal, without the need to frequently replace the channel connectors, which can improve work efficiency.

[0031] It should be noted that both the first microwave electronic switch 9 and the second microwave electronic switch 10 can be selected as multi-channel to two-channel microwave electronic switches. The microwave electronic switches can receive wireless signals. Therefore, a wireless remote control can also be configured to control the first microwave electronic switch 9 and the second microwave electronic switch 10 through the wireless remote control to achieve channel signal conversion.

[0032] In some embodiments, as Figure 1 As shown, a handle 2 is provided on the outer upper end of the cavity 1, and the provided handle 2 can facilitate carrying.

The microwave switch control interface 7 is connected to a control terminal via a cable. The control terminal can be mounted at a suitable location on the calibration device, preferably convenient for user operation. The control terminal is an existing device capable of signal control. For example, it can be a control chip mounted within a housing, with control buttons disposed on the outside of the housing. The control buttons are connected to the control chip, which is then connected to the first microwave electronic switch 9 and the second microwave electronic switch 10. The control signals inputted by the control buttons control the switching of the switching channels of the first microwave electronic switch 9 and / or the second microwave electronic switch 10.

[0036] In some embodiments, as Figure 3 As shown, a power interface 8 is provided on the second outer surface 12 , and the power interface 8 is connected to the first microwave electronic switch 9 and the second microwave electronic switch 10 . The power interface 8 is used to access a power source to provide power to the first microwave electronic switch 9 and the second microwave electronic switch 10 .

[0037] In this embodiment, considering that the interface adapter of the radio parameter comprehensive calibration device is generally used in conjunction with existing facilities and has a good power supply environment, the power supply connected to the power interface 8 can be the power grid. Of course, in some embodiments, a battery can be used to replace the power interface 8, and a corresponding battery slot is provided on the cavity 1 to install the battery, and the battery is used to power the first microwave electronic switch 9 and the second microwave electronic switch 10.

[0038] In some embodiments, the frequencies of the first microwave electronic switch 9 and the second microwave electronic switch 10 are both 10 GHz to 18 GHz.
