Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a radio frequency switch testing device. Background Art

[0002] RF switches are common devices for switching different signal paths. Since RF switches have capacitors at both the front and back ends, they cannot be tested by a multimeter in a conduction or short-circuit manner. They are usually measured manually, which also requires manual parameter adjustment and data recording during the test, resulting in a longer test cycle and lower efficiency.

[0003] The RF switch can also be tested by using a network analyzer to input a high-frequency signal, but since the network analyzer is expensive, the test cost is high. Utility Model Content

[0004] The utility model aims to provide a radio frequency switch testing device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a radio frequency switch testing device, comprising a base workbench, wherein a radio frequency transmitter and a signal display are respectively arranged on both sides of the top of the base workbench, and an inverter series group and a radio frequency switch are arranged in sequence between the radio frequency transmitter and the signal display, the output end of the radio frequency transmitter is connected to the input end of the inverter series resistor, and the input end and the output end of the radio frequency switch are respectively connected to the output end of the inverter series group and the input end of the signal display.

[0006] Preferably, the RF transmitter, inverter series resistor, RF switch and signal display are connected via a data line.

[0007] Preferably, the data cable is a dual-core data cable, which is arranged inside the base workbench.

[0008] Preferably, a storage battery is arranged inside the base workbench, and the storage battery is electrically connected to the radio frequency switch, the inverter series resistor, the radio frequency transmitter and the signal display.

[0009] Preferably, one core of the dual-core data line is disconnected, and the disconnected core is sequentially connected to an inverter series resistor and a radio frequency switch.

[0010] Preferably, the disconnected core of the data line is connected to the radio frequency switch via an I-PEX terminal.

[0011] Preferably, a protective layer is electroplated on the surface of the base workbench.

[0012] Beneficial effects of the utility model: The signal input by the RF transmitter in the device passes through a delay circuit composed of a series inverter group, so that the RF voltage reaches the voltage of the RF switch faster, which can improve the accuracy of the RF switch test. The RF signal is received by the signal display after passing through the RF switch, and the signal display on the display screen is used to judge whether the RF switch is good or not. The test data is more intuitive, the operation is simpler, and the test efficiency is effectively improved, saving human resources. In addition, the signal display is low in cost, which reduces the test cost compared with the network analyzer. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0017] Reference Figure 1 and Figure 2 The RF switch test device includes a base workbench 1, and the surface of the base workbench 1 is plated with a protective layer, and the protective layer is an insulating layer, an anti-oxidation layer and a corrosion-resistant layer from the outside to the inside. During the test process of the workbench, the protection of the test personnel is increased.

[0018] The two ends of the top of the base workbench 1 are respectively installed with a radio frequency transmitter 2 and a signal display 7, and an inverter series group 3 and a radio frequency switch 4 are sequentially arranged between the radio frequency transmitter 2 and the signal display 7. The output end of the radio frequency transmitter 2 is connected to the input end of the inverter series resistor 3, and the input end and the output end of the radio frequency switch 4 are respectively connected to the output end of the inverter series group 3 and the input end of the signal display 7. A storage battery is installed inside the base workbench 1, and the storage battery connects the radio frequency transmitter 2, the inverter series group 3, the signal display 7 and the radio frequency switch 4 through a data line, and provides power to the radio frequency switch 4, the inverter series group 3 and the signal display 7.

[0019] A data cable 6 is also provided inside the base workbench 2. The data cable 6 is a dual-core data cable, one core of which is directly connected to the RF transmitter 2 and the signal display 7, and the other core is connected to the inverter series resistor 3 and the RF switch 4 in sequence, wherein the RF switch 4 is connected to the core-broken data cable through an I-PEX terminal.

[0020] Since there are capacitors before and after the RF switch 4, when the RF transmitter 2 outputs RF voltage, if the screen of the signal display 5 shows a complete band, the RF switch 4 is good; if the screen of the signal display 5 does not show a complete band, the RF switch 4 has problems.

[0021] The inverter series group 3 is used as a delay circuit, which can delay the transmission of the RF voltage transmitted by the RF transmitter 2 to the RF switch, so that the RF voltage can adapt to and reach the voltage of the RF switch 4 more quickly, so as to improve the accuracy of the test of the RF switch 4. The device can simply and intuitively check the quality of the RF switch 4 by displaying and detecting the output band through the signal display instrument 7, thereby improving the efficiency of the inspection and reducing the test cost.

[0022] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
