Description

Technical Field

[0001] The present invention relates to an electronic device, in particular to a device for interconnecting signals between an antenna and a TR module. Background Art

[0002] T / R module, also known as transmitting and receiving module / transceiver module, is used in almost all electronic systems. Whether it is a military radar system, a satellite communication system or a common wireless communication system on the ground, the T / R module is the most basic component, but it is also the main part that affects the performance of the system. Traditional T / R modules are mainly analog devices, including inverters, amplifiers, filters, phase shifters, attenuators and other types. With the evolution of digitalization of electronic systems, T / R modules have also shifted from pure analog methods to a hybrid of analog and digital and high integration.

[0003] The interconnection between the antenna and the TR module is generally achieved through the form of upper connector + KK adapter + lower connector. For different connection spacings between the upper and lower plates, it is sometimes achieved through the form of upper connector + connecting cable + lower connector. The current mainstream connection method is the form of upper connector + connecting cable + lower connector. Although the existing interconnection technology can solve the interconnection between the antenna and the TR module, it is complicated to install and cannot be an independent module. In addition, different quadrants (quadrants are similar to coordinate quadrants, which are divided according to different channels and frequencies in antennas or TR modules to distinguish different modules) are intricate, which is a great test for installation and debugging. If one channel is damaged and needs to be replaced, other channels will be affected and cannot be disassembled and replaced independently. The debugging and installation costs are high, and it is time-consuming and labor-intensive.

[0004] The present invention divides the large switching layer into five independent modules by cutting and dividing. Different modules can be installed and debugged independently, and are easy to assemble and disassemble. The antenna and the TR end can be connected and interconnected in different seasons, and the installation and interconnection are completed innovatively. Summary of the invention

[0005] In order to solve the problems existing in the background technology, the present invention aims to provide a device for interconnecting signals between antennas and TR modules, which divides the interconnection between different elephant seasons in a cake-cutting manner, which can not only effectively ensure the interconnection between antennas and TRs, but also can be independently moduled and debugged. Through reasonable partitioning and layout, the connection between different elephant seasons is independently moduled, which is not only easy to install, but also very convenient for subsequent debugging, installation and replacement of the whole machine, thereby improving efficiency.

[0045] Embodiment 2:

[0046] The overall indication is as follows Figure 1 and 2 As shown, the whole is divided into an upper elephant quarter plate 1 and a lower elephant quarter plate 3, and a middle support enclosure (support member 2, Figure 5 As shown), installation screws, etc., are divided into 5 independent modules according to the season, and are connected and fixed by an integrated fixing member 7, such as Figure 4As shown, the overall performance is reliable and the performance is superior.

[0047] The upper elephant quarter plate 1 and the lower elephant quarter plate 3 are divided into 5 independent modules by reasonably dividing the quarters and zones, and the installation holes and installation screw positions are reserved.

[0048] The upper elephant quarter plate 1 and the lower elephant quarter plate 3 are interconnected by the upper connector 5, the connecting cable 4, and the lower connector 5. In terms of structure, the upper elephant quarter plate 1 and the lower elephant quarter plate 3 are connected and fastened by the fixing connector 8 and the fastening screws, and then the positioning pins are used to position them, so as to realize the connection and fixation between the lower plate as a whole and the cavity. Figure 3 shown.

[0049] The upper elephant quarter plate 1 and the lower elephant quarter plate 3 are fixed by fixing connectors 8 and countersunk screws, and the surrounding fixing connectors 8 are supported and connected by 32 fixing connectors 8. The installation diagram is as follows: Figure 4 After assembly, the five independent modules are connected and fixed to other cavities through the fixed connector 8. The installation diagram is shown in Figure 3 shown.

[0050] The upper quarter plate 1 and the lower quarter plate 3 are supported and fixed by the support member 2. Each module can be independent and finally form a closed whole module after installation. The installation diagram is as follows: Figure 5 shown.

[0051] The upper elephant season board 1 and the lower elephant season board 3 are divided into 5 outer areas with different shapes. This layout has two effects and meanings:

[0052] (1) It is convenient to partition the whole into independent modules, which is convenient for installation and subsequent whole machine testing;

[0053] (2) The layout of the five zones is based on the overall planning of the actual and lower board interconnection. It is not fixed, but five zones are the most reasonable and easy to operate for the current solution.

[0054] Specific implementation method:

[0055] (1) The upper elephant season plate 1 and the lower elephant season plate 3 are first divided into reasonable areas according to the requirements of the elephant season and the corresponding relationship between the hole positions of the upper and lower plates. The principle is to facilitate connection. They can be independent blocks or connected into a whole through an integrated fixing member 7;

[0056] (2) After the partitioning is completed, the upper quadrant board 1 and the lower quadrant board 3 are interconnected through the upper connector 4, the cable 5, and the lower connector 4 to achieve interconnection and signal connection of different frequency bands;

[0057] (3) The upper elephant quarter plate 1 and the lower elephant quarter plate 3 are supported and fixed by the supporting member 2 and the connecting fixing member 8 respectively. The shape is similar to "cutting a cake". They are independent of each other, but can be assembled together to form a whole.

[0058] Embodiment 3:

[0059] The upper board connector 5 and the lower board connector 5 form a path through the cable 4. The connection of the upper and lower board connectors 5 and the impedance matching of the cable 4 will directly affect the performance and indicators of the module. Therefore, it is very important to match the standing wave and impedance through the simulation model. The entire link of RF transmission needs to maintain 50 ohm matching. Figure 6 Simulation model to simulate the standing wave performance of DC-40GHz, ( Figure 6 This is the simulation model of the connector used for the upper and lower boards. The main factor affecting the link performance is the size of the connector's standing wave. Therefore, it is necessary to model and simulate the connector's standing wave to ensure performance indicators.) The standing wave simulation curve is as follows Figure 7 As shown, it can be seen that the DC-40GHz standing wave is below 1.014. Figure 8 It can be seen from the impedance matching simulation curve that the connection of the entire upper and lower board connectors and the impedance matching of the cable meet the requirement of 50±2 ohms, which can meet the matching of the entire link.
