Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of radio frequency devices, and specifically relates to a radio frequency direct sampling device with a wide frequency band and high bandwidth. Background Art
[0002] A direct RF acquisition device directly inputs RF signals into an analog-to-digital converter for digitization, eliminating the need for traditional down-conversion. Traditionally, RF signals are amplified and filtered by an RF front-end module before being converted to an intermediate frequency (IF). Direct RF acquisition simplifies this process, avoiding signal loss and interference associated with multiple frequency conversions.
[0003] Generally speaking, RF direct sampling devices need to work within a certain temperature range to ensure their performance and stability. In some special application scenarios, such as high or low temperature environments, RF direct sampling devices may need to use special materials and designs to meet working requirements. For example, in a low temperature environment, it is necessary to consider the low temperature performance of the material and the insulation measures of the device. For many RF direct sampling devices, their conventional operating temperature range may be between -20°C and 80°C, but for extreme areas, such as areas with a temperature of -40°C, RF direct sampling devices need to take some insulation measures to enable them to operate normally. This application develops a RF direct sampling device with a cold-resistant structure for extremely cold areas. Utility Model Content

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places in this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.
[0032] Furthermore, this utility is described in detail with reference to schematic diagrams. For ease of explanation, the cross-sectional views of the device structures will be partially enlarged and not to scale when describing the embodiments of this utility. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of this utility. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.
[0033] Please see the attached Figure 1-3 As shown, the present invention provides a wide-band and high-bandwidth RF direct sampling device, comprising an upper shell 1 and a lower shell 2 that are relatively covered;
[0034] The upper shell 1 includes an upper display panel 101. An extension panel 102 is provided at the inner side of the bottom of the upper display panel 101. The extension panel 102 forms a step surface with the bottom of the upper display panel 101. An inner ring panel 104 is provided on the inner side of the upper shell 1. There is a gap between the upper display panel 101 and the inner ring panel 104. A heater 4 is provided in the gap.
[0035] Specifically, the lower shell 2 includes a lower display panel 201 . Two extended panels 202 are provided on the outer sides of the top of the lower display panel 201 . The two extended panels 202 form a step with the top of the lower display panel 201 .
[0036] More specifically, the ends of the first extension plate 102 and the second extension plate 202 abut against corresponding step surfaces, so that a closed space is formed in the housing.
[0037] See also Figure 3 The outer wall of the first extension plate 102 is provided with an inwardly concave recess 103 , and the inner wall of the second extension plate 202 is provided with an outwardly convex protrusion 203 , which is adapted to be clamped in the inner part of the recess 103 .
[0038] According to the above structure, when the upper shell 1 and the lower shell 2 are installed together, the first extension plate 102 of the upper shell 1 abuts against the step surface of the second extension plate 202, and correspondingly, the second extension plate 202 of the lower shell 2 abuts against the step surface of the first extension plate 102 of the upper shell 1, forming a relatively closed space inside the shell, and the first extension plate 102 maintains a detachable fixed structure with the second extension plate 202 through the cooperation of the recess 103 and the protrusion 203, thereby blocking external water vapor from invading the interior of the shell. In extremely cold weather, it can slow down the erosion of internal equipment by cold water vapor.
[0039] See also Figure 4 The bottom side of the lower display plate 201 extends upward to form a boss 204 , and the boss 204 is in close contact with the bottom of the inner ring plate 104 .
[0040] Furthermore, the boss 204 at the bottom of the lower display plate 201 has a supporting and fixing effect on the inner ring plate 104. When the upper shell 1 and the lower shell 2 are covered, the boss 204 can limit the inner ring plate 104 so that the end portion will not be tilted.
[0041] Please see the attached Figure 1-5 A rubber sheet 3 is provided between the first extension plate 102 and the second extension plate 202. Both ends of the rubber sheet 3 are embedded in the interior of the first extension plate 102. The inner surface of the rubber sheet 3 is tightly attached to the outer wall of the first extension plate 102, and the rubber sheet 3 is also provided with an inner groove 301 that matches the recess 103.
[0042] Furthermore, the provision of the rubber sheet 3 can increase the installation friction between the first extension plate 102 and the second extension plate 202, so that they will not fall out easily. At the same time, the waterproof property of the rubber can further block the intrusion of water vapor and reduce the probability of internal water vapor condensation due to low temperature.
[0043] Please see the attached Figure 6 The heater 4 includes a heat conducting plate body 401 , on which circulation pipes 402 are evenly spaced. The circulation pipes 402 are filled with heat conducting liquid. The inner surface of the heat conducting plate body 401 is provided with protruding fins 403 .
[0044] More specifically, the heat-conducting liquid in the circulation pipe 402 is circulated internally by a built-in electric water pump to transport the heat-conducting liquid, and the internal electrical appliances are equipped with temperature sensors to monitor the temperature of the internal electrical appliances at all times, thereby keeping the electrical components inside the device working at a suitable temperature. When the temperature sensor detects that the temperature inside the shell exceeds thirty degrees, the master control chip controls the electric water pump to stop the heat cycle and continue to work using the self-heat of the internal electrical parts. When the temperature sensor detects that the temperature inside the shell is lower than ten degrees, the master control chip controls the electric water pump to continue the heat cycle.
[0045] Based on the above, the circulation pipe 402 and the protruding fins 403 are both tightly attached to the side wall of the inner ring plate 104, which can diffuse heat energy faster, so that the inside of the shell can maintain normal temperature and reduce the impact of extreme weather on the internal electrical circuits.
[0046] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
