Description

Technical Field

[0001] The invention relates to the technical field of radio frequency microwave communications, and in particular to a sector-shaped vertically fed phase shifter testing device. Background Art

[0002] With the rapid development of communication technology, phased array technology has become an important technical means for high-speed data transmission and long-distance communication in mobile communication, satellite communication, and early warning detection. The phased array system is composed of many antenna arrays and transceiver components. Each sub-array antenna has a corresponding transceiver component that is connected and can be controlled. In the transceiver component, the phase shifter plays a very important role. It is a key circuit that affects the quality of beamforming and steering capability. In FMCW radar, the phase difference between the transmitted and received signals in the transceiver component can be used to calculate the distance of the target. At the same time, by transmitting two linear frequency hopping pulses with different intervals, and then according to the received target phase difference change, the target speed can be calculated. In addition, the phase difference between the echo signals received by multiple antennas can be used to determine the target direction and realize radar angle measurement. The main function of the phase shifter is to adjust the phase of the signal. The phase shifter realizes the movement of the signal by adjusting the wave phase, ensuring that it plays a specific role in various application scenarios. In the radar communication system, it is used to adjust the phase of the transmitted signal to improve the performance and accuracy of the radar. In the guidance system, by adjusting the phase, it can help the missile adjust its flight direction, landing point, and improve flight stability.

[0003] Phase shifter circuit is an irreplaceable and important device in the fields of mobile communication, satellite communication, early warning detection, etc. Its main device parameter indicators include insertion loss, parasitic amplitude modulation, phase shift accuracy, port standing wave, etc. Since the phase shifter circuit has many control bits and many combination states, the test power supply and control are relatively cumbersome. Therefore, the test and verification of phase shifter circuit indicators have become an urgent problem to be solved.

[0004] Conventional phase shifting structures are single in form and are usually fixed by screws in communication system design. They lack flexibility and are rarely used in intelligent test systems. Moreover, when testing the phase shifter alone, conventional testing methods are limited by the structural form. When a specific low-frequency connector is selected for feeding testing, it is extremely inconvenient to repeatedly remove and take it out. When insulator feeding is selected, the distribution of the feeding pins may be irregular due to the internal circuit layout, and non-standard sockets need to be customized to connect with them, which increases product costs. Furthermore, this method is easily affected by the length of the insulator pins during installation and positioning, which can easily cause certain deviations during positioning, and cannot be quickly plugged in and installed, and manual intervention and calibration are required. Furthermore, in the process of repeated calibration and installation, the gold plating layer on the surface of the insulator will be damaged to a certain extent, seriously affecting the electrical performance indicators of the phase shifter. In addition, when the wire harness is directly welded on the insulator for feeding control, solder will remain on the surface of the insulator, affecting the appearance of the product and causing many complaints from customers.

[0005] Therefore, when the phase shifter is used in the intelligent automatic test turntable equipment, it is of great significance to have the characteristics of rotation and precise positioning, and the novel structure also appropriately interprets this characteristic. Based on the above, inventing a phase shifter and its separate test device that can be used in the intelligent automatic test turntable equipment to achieve precise transfer positioning and novel structure is a topic worth studying for product design engineers.

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] A phase shifter test device with vertical fan-shaped feed, such as Figure 8 As shown, it includes a support plate mechanism, a mounting platform mechanism, a contact plate mechanism, a cone disk mechanism, a processor unit and an ejector mechanism. The contact plate mechanism is connected to the processor unit. The mounting platform mechanism is provided with a concave platform for installing the support plate mechanism and the cone disk mechanism. The inner wall of the concave platform of the mounting platform mechanism is provided with fan-shaped notched surfaces. The contact plate mechanism is fixedly installed on the notched surface of the inner wall of the concave platform of the mounting platform mechanism. The support plate mechanism is fixedly connected to the mounting platform mechanism. The cone disk mechanism is connected to the mounting platform mechanism. The ejector mechanism is installed in the support plate mechanism. The cone disk mechanism is controlled to push the ejector mechanism during the descending process of the mounting platform mechanism, so that the feeding contact pin of the phase shifter is attached to the contact plate mechanism to realize feed-through for phase shifter testing.

[0045] The phase shifter is provided with a radio frequency connector for transmitting the phase shift signal, such as Fig.12 As shown, the bottom end of the phase shifter is provided with vertically distributed feeding pins, the inner side of the phase shifter is provided with an internal gear structure, and the side wall of the phase shifter is provided with a groove for structural limitation and guiding transportation. Optionally, the structural shape of the phase shifter is fan-shaped, the feeding pins are vertically distributed on the fan-shaped circumference of the phase shifter, and the side wall of the phase shifter is provided with a semicircular groove.

[0046] For example, the phase shifter is provided with an RF connector for phase shift signal transmission. The RF input end can be set at one end of the phase shifter, and the RF output end can be set at the other end of the phase shifter. The RF connector is installed perpendicular to the sector surface of the phase shifter to realize the input and output of the phase shift signal. The semicircular groove on the side wall of the phase shifter is used to achieve structural limitation and guide transportation when testing with the automatic test turntable equipment, ensuring that it can only move smoothly on the plane of the turntable test equipment, thereby realizing precise transportation positioning and completing automated testing.

[0047] like Figure 1 , 6As shown, the side wall of the support plate mechanism is provided with a first countersunk hole for installing the ejector mechanism. The number of the first countersunk holes can be set according to the actual use situation, and the first countersunk holes of the support plate mechanism used for installing the ejector mechanism are all within the protection scope of this application. Optionally, the structural shape of the support plate mechanism is fan-shaped, and the number and position of the countersunk holes of the support plate mechanism are adapted to the feeding contact pins of the phase shifter. In order to further improve the fixing of the ejector mechanism in the first countersunk hole of the support plate mechanism, an ejector fixing hole is set at the corresponding place of the first countersunk hole of the support plate mechanism, which is used to fix the ejector mechanism in the first countersunk hole of the support plate mechanism by screws. Optionally, the support plate mechanism is provided with a second countersunk hole for fixing the support plate mechanism on the mounting platform mechanism, so as to realize the fixed connection between the support plate mechanism and the mounting platform mechanism. Optionally, in order to further improve the fixing of the phase shifter on the support plate mechanism, the support plate mechanism is provided with a phase shifter fixing hole for fixing the phase shifter on the support plate mechanism to avoid the phase shifter from moving during the test, causing errors in the phase shifter test to affect the test accuracy.

[0048] like Figure 4 As shown, the bottom end of the cone-disk mechanism is provided with a connecting component for realizing spiral lifting on the mounting platform mechanism, and the side wall of the cone-disk mechanism is conical. The conical side wall of the cone-disk mechanism is used to make the feeding contact pin of the phase shifter fit to the U-shaped strip line of the contact plate to realize feed-through when the cone-disk mechanism pushes the ejector mechanism during the descent of the mounting platform mechanism. Optionally, a rotary handle component is provided at the top end of the cone-disk mechanism to facilitate spiral lifting of the cone-disk mechanism on the mounting platform mechanism by operating the rotary handle component. The number and position of the rotary handle components can be set according to actual usage.

[0049] For example, the bottom end of the cone-disk mechanism is provided with a connecting component for realizing spiral lifting on the mounting platform mechanism, and the connecting component of the cone-disk mechanism is provided with an external thread that can be screwed on the mounting platform structure, thereby realizing the spiral lifting function of the cone-disk mechanism on the mounting platform structure. The side wall of the cone-disk mechanism is conical, and the slope and length of the conical surface of the side wall of the cone-disk mechanism can be set according to the actual use situation, so that when the cone-disk mechanism pushes the ejector mechanism during the descent of the mounting platform structure, the feeding contact pin of the phase shifter can be effectively attached to the U-shaped belt line of the contact plate mechanism to realize feed-through. The axial movement stroke of the ejector mechanism is generally based on the length of the feeding contact pin of the phase shifter and its own yield strength, and is confirmed by finite element simulation to ensure that this stroke will not cause the feeding contact pin to deform. The top of the cone-disk structure can be provided with two rotary handle components, which is convenient for the operator to control the lifting and lowering of the cone-disk structure when rotating it.

[0050] like Figure 2As shown, the mounting platform mechanism is provided with a recessed platform for mounting the support plate mechanism and the cone disk mechanism, and the inner wall of the recessed platform of the mounting platform mechanism is provided with fan-shaped notched surfaces. The support plate mechanism can be fixed to the mounting platform mechanism by means of the support plate threaded holes provided on the mounting platform mechanism, and the mounting platform mechanism is provided with cone disk threaded holes adapted to the connecting parts of the cone disk mechanism, so as to realize the spiral lifting and lowering of the cone disk mechanism on the mounting platform mechanism, wherein, during the descending process of the mounting platform structure, the conical side wall of the cone disk mechanism pushes the ejector mechanism so that the feeding contact pin of the phase shifter can be effectively attached to the U-shaped strip line of the contact plate mechanism to realize feed-through. The notched surface of the inner wall of the recessed platform of the mounting platform mechanism can be electrochemically plated to meet the process requirements of the sintered mounting contact plate mechanism and ensure good conductive grounding characteristics.

[0051] like Figure 3 As shown, the contact plate mechanism can use a conventional FR4 board, the back of the contact plate mechanism is all bright copper, and the front of the contact plate mechanism is provided with a U-shaped strip line, the width of which is determined based on the outer diameter of the feeding contact pin of the phase shifter of the vertical sector feed to meet the contact reliability requirements. By welding the high-temperature wire, the U-shaped strip line is welded to the processor unit, so as to realize the feed-through of the feeding contact pin and the processor unit to complete the test function. The outer contour of the contact plate structure is adapted to the inner wall defect of the concave platform of the mounting platform mechanism. Corresponding pads are set at corresponding positions on the inner edge of the sector of the processor unit, corresponding to the U-shaped strip line, and a low-frequency connector is installed on the processor unit for applying circuit control. For example, the contact plate mechanism is installed on the inner wall defect of the concave platform of the mounting platform mechanism. Since there is an isolation boss between each contact plate, good feeding control independence is guaranteed, and no electrical interference will occur. While the processor unit is mounted on the mounting platform, the U-shaped strip line of the contact plate is welded to the corresponding pad of the processor unit using a high-temperature wire to realize feed-through.

[0052] like Figure 5 As shown, the ejector mechanism includes an ejector component, an elastic component, a column component, a dielectric column component and a terminal component. The column component is a hollow structure. The ejector component is provided with a stopper. One end of the column component is provided with an ejector hole. The other end of the column component is connected to the terminal component. The terminal component is provided with an ejector hole. One end of the ejector component is connected to the dielectric column component. The length of the elastic component and the position of the stopper, and the length of the hollow structure of the column component can be set according to actual use. Optionally, the elastic component can be a spring component, which is not specifically limited in this application.

[0053] For example, the hollow structure column cavity of the column component is a stepped flat-bottomed light hole, the other end of the column component is provided with an internal thread for connecting with the end head, the end head component is provided with an external thread, and the end head component is provided with an ejector hole, through which the ejector component can pass. The outer diameter of the column component is adapted to the large aperture size of the first countersunk hole of the support plate mechanism, so that the ejector mechanism can be installed in the first countersunk hole of the support plate mechanism. The ejector component is provided with a limiter for limiting the spring. Preferably, the other end of the ejector component is spherical to ensure smooth contact with the conical side wall of the cone disk mechanism. One end of the ejector component is connected to the dielectric column component, and the dielectric column component can be made of polytetrafluoroethylene and has a certain plasticity. The specific assembly method of the ejector mechanism is: first install the spring component on the ejector component and install it in the column cavity of the column component, screw it through the end head component, and install the dielectric column component at one end of the ejector component emerging from the other end of the column cavity of the column component.

[0054] When using, if Fig. 9 As shown, the cone disk mechanism is spirally lifted and lowered on the mounting platform mechanism by operating the rotary handle component. During the descent of the mounting platform structure, the cone disk mechanism pushes the ejector mechanism through the conical side wall of the cone disk mechanism, so that the feeding contact pin of the phase shifter can effectively fit onto the U-shaped strip line of the contact plate mechanism to achieve feed-through. The processor unit is respectively connected to the RF input port and the RF output port of the phase shifter to test the indicators. The results are shown in FIG. Fig.10 , Fig.11 After the test is completed, the cone disk mechanism is raised on the mounting platform structure by operating the rotary handle component. Due to the action of the elastic component of the ejector mechanism, the dielectric column component on the ejector mechanism moves in a fan-shaped axial convergence shape, so that the feeding contact pin of the fan-shaped vertically fed phase shifter is separated from the contact plate mechanism, and the fan-shaped vertically fed phase shifter can be removed, completing the entire phase shifter test process.

[0055] For example, to test the phase shifter parameter indicators, set the frequency to 6 GHz and the cutoff frequency to 18 GHz, set the input power to -30 dBm, and obtain the phase shifter RF signals with different phases (-5.625°, -11.25°, -22.5°, -45°, -90°, -180°) for testing, and obtain the insertion loss-frequency curve and the phase shift degree-frequency curve (such as Fig.10 , Fig.11 As shown in the figure, within the basic phase range of -5.625°, -11.25°, -22.5°, -45°, -90°, and -180°, if the insertion loss is less than 14dB, the phase shifter test result is determined to meet the test condition requirements.
