Description

Radio frequency connector, server testing equipment, and server testing method

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on June 14, 2023, with application number 202310700506.2, and application name “RF Connector, Server Test Equipment and Server Test Method”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of signal testing, and in particular to a radio frequency connector, a server testing device, and a server testing method. Background Art

[0004] High-speed signal testing requires various SMA (Small A Type) RF connectors. These connectors are screwed into the test board's PCB through mounting holes. The board typically contains numerous SMA connectors, each connected to a different signal under test. In actual use, some SMA connectors are connected to the test instrument via cable connectors, while others are typically terminated with 50-ohm loads to prevent signal reflections and crosstalk, which can interfere with test results.

[0005] The 50Ω load and cable connector are both male, while the SMA RF connector is female. The middle contact probe transmits the signal, while the outer shell is grounded. The male and female connectors are screwed together, and the male pins insert into the female holes to establish a signal connection.

[0006] While this method can shield unused SMA RF connectors, the 50Ω loads used are typically expensive, leading to higher testing costs. Furthermore, the large number of unused SMA RF connectors during testing necessitates the installation of numerous 50Ω loads. These loads also need to be swapped when changing test signals, creating a significant workload. Furthermore, repeated installation of 50Ω loads can cause wear and tear on both the SMA RF connectors and the 50Ω loads themselves, increasing the risk of damage.

At this time, the shaft can contact the probe and thus be conductive to the cable. The above-mentioned setting method allows the load to be directly integrated and installed in the RF connector or integrated on the test board, so there is no need to set up a separate load element. Compared with a separate load element, the cost of integrated setting of the load is greatly reduced, which is conducive to reducing the test cost. At the same time, since the load does not need to be operated during use, it is only necessary to plug and unplug the cable connector to the RF connector normally, which greatly reduces the manual workload and is conducive to improving test efficiency.

DETAILED DESCRIPTION

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0039] In order to solve the problem of high cost in signal testing in related technologies, the embodiments of the present application provide a radio frequency connector, a server testing device, and a server testing method.

[0040] A radio frequency connector as shown in Figures 1 to 6 includes a housing 10, a shaft 20, a first connector 30 and a second connector 40. The shaft 20 is arranged in the housing 10, and the shaft 20 has a docking hole 21 for docking with an external component; one of the first connector 30 and the second connector 40 is electrically conductive with the shaft 20, and the other of the first connector 30 and the second connector 40 is electrically conductive with the load 60. The second connector 40 is movably arranged and has a conductive state in contact with the first connector 30 and a separated state separated from the first connector 30. The second connector 40 has a driving end located in the docking hole 21. When the driving end is not subjected to force, the second connector 40 is in the conductive state, and the shaft 20 is electrically connected to the load 60; when an external component applies force to the driving end, the second connector 40 is in the separated state, and the shaft 20 is electrically disconnected from the load 60.

[0041] In this embodiment, a first connector 30 and a second connector 40 are provided. One of the first connector 30 and the second connector 40 is electrically conductive with the shaft 20, and the other of the first connector 30 and the second connector 40 is electrically conductive with the load 60. The first connector 30 and the second connector 40 do not maintain contact and conduction, but can switch between a conductive and a disconnected relationship. When the RF connector is not connected to an external component, namely the cable connector 70, the second connector 40 and the first connector 30 are in a conductive state. At this time, the shaft 20 is electrically conductive with the load 60 through the first connector 30, the second connector 40, and the load 60, thereby achieving conduction between the RF connector and the load 60. When the RF connector is connected to the cable connector 70, the probe of the cable connector 70 is inserted into the docking hole 21. When the probe is inserted into the docking hole 21, it drives the driving end to move, thereby driving the second connector 40 to move. The second connector 40 switches from a conductive state to a disconnected state, the first connector 30 and the second connector 40 are separated and electrically disconnected, and the shaft 20 and the load 60 are no longer conductive. At this time, the shaft 20 can contact the probe and thus conduct electricity with the cable. The above-mentioned setting method allows the load 60 to be directly integrated and installed in the RF connector or on the test board, so that there is no need to set up a separate load 60 component. Compared with a separate load 60 component, the cost of integrating the load 60 is greatly reduced, which is conducive to reducing testing costs. At the same time, since the load 60 does not need to be operated during use, it is only necessary to plug and unplug the cable connector 70 normally, which greatly reduces the manual workload and is conducive to improving testing efficiency. In addition, since the load 60 does not need to be plugged and unplugged, it is conducive to extending the service life of the load 60.

[0042] This embodiment is described by taking the RF connector used in server test equipment as an example, and the load 60 adopts a 50-ohm load 60. Of course, the RF connector can also be used in other test equipment, or other equipment and components that require the installation of RF connectors. At the same time, this embodiment is described by taking the first connector 30 and the shaft 20 as always in contact and conductive, and the second connector 40 as always conductive with the load 60 as an example. Of course, the above two can also be interchanged, that is, the first connector 30 is conductive with the load 60, and the second connector 40 is conductive with the shaft 20. In addition, the conduction and disconnection mentioned in this embodiment are in the electrical sense, that is, the two parts that are conductive can directly or indirectly transmit signals, and the two parts that are disconnected cannot transmit signals.

[0043] As shown in Figures 3 to 5, in this embodiment, the second connecting member 40 adopts a movement mode of axial movement along the shaft body 20. The second connecting member 40 includes a docking portion 41 and a driving portion 42, wherein the docking portion 41 is mainly used to dock with the first connecting member 30, and plays the role of conducting the shaft body 20 and the load 60. Therefore, the first connecting member 30 and the docking portion 41 are both conductors. At the same time, there is a constant conduction relationship between the docking portion 41 and the load 60. In this way, when the second connecting member 40 switches between the conducting state and the separated state, the docking portion 41 can switch between the state of contact and conduction with the first connecting member 30 and the state of separation from the first connecting member 30, thereby realizing the conduction and disconnection between the first connecting member 30 and the second connecting member 40. The driving portion 42 cooperates with the cable connector 70. The driving portion 42 and the docking portion 41 are directly or indirectly connected together, so that the second connector 40 moves as a whole. The driving portion 42 is located in the docking hole 21, and the end of the driving portion 42 facing the opening side of the docking hole 21 serves as the driving end. In this way, when the cable connector 70 is inserted into the docking hole 21, its probe can be pressed against the end face of the driving end of the driving portion 42. As the cable connector 70 is inserted, the probe squeezes the driving end to move the driving portion 42, which also causes the docking portion 41 to move and separate from the first connector 30, thereby achieving the effect of switching the second connector 40 from a conductive state to a separated state.

[0044] Preferably, the docking portion 41 is further away from the opening of the docking hole 21 than the first connector 30, as shown in Figures 1 and 5. This arrangement is based on the fact that when the cable connector 70 is inserted into the RF connector, the force exerted by the probe on the driver 42 is primarily a pushing force. Therefore, the first connector 30 is positioned between the docking portion 41 and the opening of the docking hole 21. Thus, when the probe is inserted into the docking hole 21, it can directly push the driver end, causing the driver end to move toward the docking hole 21, thereby causing the docking portion 41 to move toward the docking hole 21 and separate from the first connector 30.

[0045] Of course, the docking portion 41 can also be set on the side close to the opening side of the docking hole 21. At this time, the probe directly pushes the driving portion 42 to achieve the separation of the docking portion 41 and the first connecting member 30, and other structures need to be additionally set, such as U-shaped ribs. The U-shaped ribs themselves have certain movement capabilities. One end of the U-shaped ribs is exposed at the docking hole 21, and the other end is in contact with the second connecting member 40. At this time, the probe directly pushes one end of the U-shaped ribs to move in the direction of extending into the docking hole 21. Since the U-shaped ribs move along the extension direction of their own structure, the other end of the U-shaped ribs moves in the direction of extending out of the docking hole 21, thereby driving the second connecting member 40 to move, so that the docking portion 41 is separated from the first connecting member 30.

[0046] In this embodiment, both the first connector 30 and the second connector 40 have an annular structure, and the annular structure is arranged on the outer peripheral side of the shaft body 20. In order to ensure reliable cooperation between the first connector 30 and the docking portion 41, in this embodiment, both the docking portion 41 and the first connector 30 are arranged in an annular shape, that is, the first connector 30 as a whole is an annular structure, and the docking portion 41 of the second connector 40 is an annular structure, and both are arranged on the outer peripheral side of the shaft body 20. Of course, the first connector 30 and the docking portion 41 can also adopt other shapes. For example, the first connector 30 and the docking portion 41 are embedded in the housing 10 with a block structure, wherein the first connector 30 can be in contact with the shaft body 20, while the docking portion 41 does not contact the shaft body 20, and so on. The embodiments are not limited to the embodiments of this embodiment.

[0047] At the same time, considering that the first connecting member 30 needs to maintain contact with the shaft body 20, while the docking portion 41 cannot be in direct contact with the shaft body 20, the inner diameter of the first connecting member 30 in this embodiment is approximately the same as the outer diameter of the shaft body 20, while the inner diameter of the docking portion 41 is larger than the outer diameter of the shaft body 20, so that the inner diameter of the first connecting member 30 is smaller than the inner diameter of the docking portion 41. In this way, the first connecting member 30 naturally maintains a constant contact and conductive relationship with the shaft body 20, while the docking portion 41 and the shaft body 20 always maintain a non-direct contact relationship. At the same time, because the driving portion 42 needs to move within the docking hole 21, the diameter of the driving portion 42 needs to be slightly smaller than the diameter of the docking hole 21 to ensure smooth movement. Of course, the specific matching method is not limited to the above-mentioned method of this embodiment. When its setting method changes, its matching relationship can also be changed accordingly, as long as the above-mentioned effect can be achieved.

[0048] In actual processing, the first connecting member 30 and the docking portion 41 can both be embedded in the housing 10, with the first connecting member 30 being fixedly embedded and the second connecting member 40 being movably embedded. Of course, a portion of the first connecting member 30 can also be embedded in the shaft body 20, or other processing methods can be used. The specific processing method can be one-piece molding or subsequent assembly, or the housing 10 can be divided into multiple parts, and the parts can be spliced ​​to form the entire housing 10. In this case, when the parts of the housing 10 are spliced, the first connecting member 30 and the second connecting member 40 can be installed in the housing 10, thereby achieving component assembly.

[0049] It should be noted that the housing 10 is a non-conductor, and the docking portion 41 cannot achieve electrical conduction between the housing 10 and the shaft 20 .

[0050] As shown in FIG4 , in this embodiment, the second connector 40 further includes a connecting portion 43, which serves to connect the docking portion 41 and the driving portion 42. That is, the driving portion 42 and the docking portion 41 are connected via the connecting portion 43, thereby forming the second connector 40 as a whole. Since the driving portion 42 will contact the probe of the cable connector 70, and the docking portion 41 is a conductor, in order to prevent the probe from being electrically connected to the docking portion 41 and the load 60 through the driving portion 42 and the connecting portion 43, at least one of the connecting portion 43 and the driving portion 42 can be configured as a non-conductor, thereby achieving electrical disconnection between the probe and the docking portion 41. Considering that both the connecting portion 43 and the driving portion 42 may contact the shaft 20, in this embodiment, it is preferred that both the connecting portion 43 and the driving portion 42 are non-conductors.

[0051] Since docking hole 21 is generally a cylindrical hole of a certain length, the driving portion 42 of this embodiment adopts a cylindrical shape that matches the shape of docking hole 21. This allows the driving portion 42 to move only axially within docking hole 21, ensuring stable and reliable movement. The driving portion 42 is located at the axis of the annular docking portion 41, and the axes of the driving portion 42 and docking portion 41 coincide with each other. The connecting portion 43 is arranged radially to connect the driving portion 42 and docking portion 41.

[0052] It should be noted that the axial length of the driving part 42 can be set as needed. When the second connecting member 40 is in the on state, the driving end of the driving part 42 can extend out of the docking hole 21 or not. As long as the probe of the cable connector 70 is inserted into the docking hole 21, it can push the driving part 42 to move, so that the second connecting member 40 is switched to the separated state.

[0053] Considering that the driving portion 42 is within the docking hole 21, while the docking portion 41 is located outside the shaft body 20, the connecting portion 43 needs to be inserted into the shaft body 20. Therefore, in this embodiment, an escape channel is radially opened on the shaft body 20 for circumventing the connecting portion 43. The connecting portion 43 is inserted into the escape channel, thereby achieving connection with the inner driving portion 42 and the outer docking portion 41. At the same time, considering that the second connecting member 40 has axial movement, the escape channel not only radially penetrates the shaft body 20 but also extends axially for a certain length, thereby providing sufficient space for the movement of the connecting portion 43 and ensuring the axial movement of the second connecting member 40.

[0054] Optionally, the number of connecting parts 43 can be set as needed, and one or more can be set. In this embodiment, four connecting parts 43 are provided, and the four connecting parts 43 are arranged at equal intervals along the circumference of the docking part 41, thereby ensuring the stability of the synchronous movement between the docking part 41 and the driving part 42.

[0055] Accordingly, when there are multiple connecting parts 43, the number of avoidance channels can also be increased accordingly. Preferably, the connecting parts 43 and the avoidance channels are arranged in a one-to-one correspondence, so as to ensure that each connecting part 43 can reliably move axially. Of course, multiple avoidance channels can also be connected to form a large channel, and multiple connecting parts 43 can be simultaneously passed through the large channel. However, it should be noted that in order to ensure the integrity of the shaft body 20, the large channel cannot cover all cross sections of the shaft body 20. Alternatively, the shaft body 20 can be divided into two axial segments, and the two segments are connected together by ribs to form a whole. In this case, a channel for the connecting part 43 to pass through and move is naturally formed between the two segments.

[0056] As shown in Figures 2 and 6, in this embodiment, the movement of the second connector 40 from the conductive state to the disconnected state is achieved by the push of the cable connector 70, while the movement from the disconnected state to the conductive state is achieved by the reset member 50. Specifically, the RF connector also includes a reset member 50, which can be a spring or other component. One end of the reset member 50 is connected to the side of the docking portion 41 of the second connector 40 away from the first connector 30, and the other end of the reset member 50 can be connected to the housing 10 or to the ground portion on the test board. Since the housing 10 of this embodiment is entirely non-conductive, the reset member 50 of this embodiment is in contact with the ground portion on the test board, and one end of the load 60 is also in contact with the ground portion, thereby achieving the grounding requirement. The reset member 50 can drive the second connecting member 40 to move toward the conductive state, so that the second connecting member 40 always has a tendency to move to the conductive state. When the cable connector 70 is not connected to the RF connector or is unplugged from the RF connector, the second connecting member 40 is switched from the separated state to the conductive state under the action of the reset member 50, thereby realizing automatic conduction between the RF connector and the load 60 when not in use, while ensuring the reliability of maintaining conduction between the shaft body 20 and the load 60.

[0057] As shown in FIG2 , in this embodiment, considering that the second connector 40 is movable, it may be inconvenient to directly connect it to the load 60. Therefore, in this embodiment, the reset member 50 is also configured as a conductor, and the reset member 50 is directly electrically connected to the load 60. The reset member 50 is also connected to the docking portion 41, thereby achieving electrical connection between the docking portion 41 and the load 60 through the reset member 50. Of course, in addition to the reset member 50, other components can also be used to achieve electrical connection between the load 60 and the docking portion 41, or a structure can be provided to achieve a stable and reliable connection between the docking portion 41 and the load 60.

[0058] Optionally, the specific number of reset members 50 can be set as needed, and one or more reset members can be provided. In this embodiment, two reset members 50 are provided, and the two reset members 50 are located on opposite sides of the second connecting member 40 in the circumferential direction. This ensures that the reset members 50 apply force evenly to the docking portion 41, avoiding situations such as unsmooth movement or even jamming caused by force on one side of the docking portion 41. Four reset members 50 can also be provided. Similar to the connecting portion 43, four reset members 50 are arranged at equal intervals around the docking portion 41 in the circumferential direction.

[0059] In this embodiment, the housing 10 includes a central main body portion and connecting portions located on both sides of the main body portion. A receiving cavity is defined in the central portion of the main body portion, and the shaft body 20 is disposed within the receiving cavity. The receiving cavity in this embodiment includes a first section and a second section connected in sequence, wherein the first section is free of components and is used to connect to the cable connector 70, while the second section accommodates the shaft body 20, i.e., the shaft body 20 is located in the second section, and the connecting hole 21 of the shaft body 20 is connected to the first section. In this way, when the cable connector 70 is inserted into the receiving cavity, the probe passes through the first section and is inserted into the connecting hole 21, and the end of the cable connector 70 is inserted into the first section, thereby playing a positioning and guiding role, ensuring stable connection between the RF connector and the cable connector 70.

[0060] The connecting portion is provided on the side of the main body. In this embodiment, two connecting portions are provided, located on either side of the main body. The main body serves as the primary mounting and housing portion of the housing 10, while the connecting portion connects the housing 10 to the test board. Specifically, in this embodiment, mounting holes are provided on the connecting portion, which mate with vias on the test board. Bolts and other components are used to secure the connecting portion to the test board, thereby securing the RF connector to the test board and achieving installation of the RF connector. Of course, the specific structure of the housing 10 is not limited to the above-described structure of this embodiment and can be adjusted and modified as needed.

[0061] Optionally, the inner sidewall of the first section and / or the outer sidewall of the first section have a connection structure for docking with an external component. In this embodiment, external threads are provided on the outer sidewalls of the first section and the second section. The external threads serve as a connection structure, thereby being able to mate with the internal threads on the cable connector 70. When in use, the operator simply screws the cable connector 70 into the RF connector via the threaded structure. During this process, the probe can push the drive unit 42, causing the second connector 40 to switch to a separated state, thereby disconnecting the load 60 from the shaft body 20 and connecting the probe to the shaft body 20.

[0062] Optionally, in this embodiment, a non-equal diameter arrangement is adopted between the first and second sections. That is, the diameters of the first and second sections are not equal. More specifically, the diameter of the first section is larger than that of the second section. In this way, on the one hand, the larger diameter of the first section enables better docking and guiding with the cable connector 70. On the other hand, the thicker thickness of the second section provides space for embedding the first connector 30, the second connector 40, etc., reducing the impact of the arrangement of the first connector 30 and the second connector 40 on the overall size of the component, which is conducive to miniaturization. At the same time, a step structure is naturally formed between the first and second sections. The step structure can limit the position of the cable connector 70 when it is plugged into the RF connector. When the end of the cable connector 70 hits the step structure, it indicates that the cable connector 70 is docked in place and the cable connector 70 cannot be screwed in further, thereby avoiding problems such as over-docking and inability to be removed, thereby ensuring reliability of use.

[0063] In order to ensure reliable cooperation between the shaft body 20 and the probe, this embodiment provides a spring clip on the inner wall of the docking hole 21. The spring clip is a conductor and can adopt a petal structure. The petal structure is combined with the elasticity of the spring clip itself, so that when the probe is inserted into the docking hole 21, the petal structure can clamp the probe, thereby ensuring contact between the probe and the spring clip. In this way, conduction is achieved through the spring clip and the shaft body 20, thereby ensuring the reliability of contact and conduction.

[0064] This embodiment also provides a server testing method, which uses the above-mentioned RF connector. The server testing method includes: when the external component is not plugged in, the second connecting component 40 is in a conductive state, the second connecting component 40 is in contact with the first connecting component 30, and conduction is achieved between the shaft 20 and the load 60; when the external component is plugged in, the external component applies force to the driving end and drives the second connecting component 40 to switch to a separated state, the second connecting component 40 is separated from the first connecting component 30, and the shaft 20 and the load 60 are disconnected.

[0065] In this embodiment, the server testing method further includes: when the external component is plugged in, the external component contacts the docking portion 41 and pushes the docking portion 41 to drive the driving portion 42 to move, and the driving portion 42 is separated from the first connecting member 30.

[0066] In this embodiment, the server testing method further includes: when the external component is unplugged after plugging, the reset member 50 drives the second connecting member 40 to move to the conductive state, the second connecting member 40 contacts the first connecting member 30 again, and the shaft 20 and the load 60 are connected again.

[0067] The server testing method of this embodiment, that is, the specific matching process of the RF connector and the cable connector 70 is as follows:

[0068] For an unused RF connector, the cable connector 70 is not inserted into the RF connector, and the second connector 40 is kept in a conductive state driven by the reset member 50. At this time, the docking portion 41 is in contact with the first connector 30 and conductive, and the shaft 20 is conductive with the load 60 through the first connector 30, the docking portion 41, and the reset member 50.

[0069] For the RF connector that needs to be used, the cable connector 70 is inserted into the RF connector, and the probe of the cable connector 70 is inserted into the docking hole 21. The probe pushes the driving end of the driving part 42 to switch the second connecting part 40 to the separated state. At this time, the docking part 41 is separated from the first connecting part 30, and the two are no longer conductive, so that there is no conductivity between the shaft body 20 and the load 60. The shaft body 20 is conductive through the cable connected to the probe and the cable connector 70, which can realize signal transmission. At the same time, the reset part 50 is compressed during the movement of the second connecting part 40, so that the reset part 50 stores elastic force for subsequent reset. After the cable connector 70 is inserted, it is rotated and tightened on the RF connector through the threaded structure, thereby achieving a stable connection with the RF connector.

[0070] When the cable connector 70 is unplugged after use, the cable connector 70 is rotated in the opposite direction and unscrewed from the RF connector. During the process of the probe withdrawing from the docking hole 21, the reset member 50 acts on the second connector 40, causing the second connector 40 to move along with the probe until it switches to the conductive state. At this time, the docking portion 41 of the second connector 40 abuts against the first connector 30, causing the shaft 20 to be re-connected to the load 60 through the first connector 30, the docking portion 41, and the reset member 50, and the probe withdraws from the docking hole 21, so that it is no longer conductive to the RF connector.

[0071] Since multiple RF connectors are installed on the test board at the same time during actual use, some of the RF connectors will be used and need to be docked with the cable connector 70, while the remaining RF connectors will not be used and will not be docked with the cable connector 70. As a result, the above-mentioned two situations of using RF connectors and not using RF connectors will appear on the same test board at the same time.

[0072] It should be noted that, in the above embodiments, a plurality refers to at least two.

[0073] From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:

[0074] The technical solution of this embodiment is to provide a first connector 30 and a second connector 40, one of the first connector 30 and the second connector 40 is electrically connected to the shaft 20, and the other of the first connector 30 and the second connector 40 is electrically connected to the load 60, and the first connector 30 and the second connector 40 are not kept in contact and conductive, but can be switched between a conductive and disconnected relationship. When the RF connector is not connected to an external component, that is, a cable connector 70, the second connector 40 and the first connector 30 are in a conductive state. At this time, the shaft 20 is electrically connected to the load 60 through the first connector 30 and the second connector 40. The two connectors 40 are electrically conductive with the load 60, thereby achieving electrical connection between the RF connector and the load 60. When the RF connector is docked with the cable connector 70, the probe of the cable connector 70 is inserted into the docking hole 21. When the probe is inserted into the docking hole 21, it drives the driving end to move, thereby driving the second connector 40 to move, causing the second connector 40 to switch from the conductive state to the disconnected state. The first connector 30 and the second connector 40 are separated and electrically disconnected, and the shaft 20 and the load 60 are no longer conductive. At this time, the shaft 20 can contact the probe and achieve electrical connection with the cable. The above-mentioned configuration allows the load 60 to be directly integrated into the RF connector or integrated into the test board, thereby eliminating the need for a separate load 60 component. Compared with a separate load 60 component, the cost of integrating the load 60 is greatly reduced, thereby reducing testing costs. At the same time, since the load 60 does not need to be operated during use, only the cable connector 70 needs to be normally plugged and unplugged into the RF connector, which greatly reduces manual labor and improves testing efficiency. In addition, the load 60 does not need to be plugged and unplugged, which helps extend the service life of the load 60.

[0075] The RF connector of this embodiment automatically terminates with an internal 50-ohm load when not in the test connection state. In the test connection state, the 50-ohm load is automatically disconnected and the test state is entered, eliminating the need for manual disassembly and assembly of the 50-ohm load. This can provide the following benefits:

[0076] 1. For connector manufacturers, the new SMA RF connector combines the SMA itself and the 50 ohm load into one, saving materials.

[0077] 2. For test manufacturers, it saves the need to purchase a large number of 50-ohm load components, greatly reducing test costs.

[0078] 3. Eliminate the need for manual installation and removal of 50 ohm loads on the test board.

[0079] 4. During the test, you only need to replace the connection between the measured signal and the cable connector, and there is no need to replace the 50-ohm load connection, which reduces the chance of damage to the SMA RF connector.
