Description

Technical Field

[0001] This application relates to the field of amplifier technology, in particular to low-noise down-amplifiers, specifically an eight-output Ku-band high-frequency head structure. Background Technology

[0002] A low-noise block downconverter (LNB) is a low-noise downconverter amplifier consisting of a mixer and a local oscillator. LNBs are generally classified as Ku-band LNBs (3.4GHz-4.2GHz) and Ku-band LNBs (10.7GHz-12.75GHz). Because satellite signals are quite weak before reaching the antenna, and signal loss increases with higher frequencies transmitted via coaxial cable, LNBs are needed to amplify the signal while minimizing the degradation of the signal-to-noise ratio. The LNB's workflow involves first amplifying the high-frequency satellite signal, then using the local oscillator circuit, depending on the LNB type, converting the high-frequency satellite signal to an intermediate frequency (IF) of 950MHz-2150MHz for further amplification to facilitate coaxial cable transmission and demodulation by the satellite receiver.

[0003] Traditional LNBs can only connect one user at a time, which is inconvenient due to the limited number of connected users. Utility Model Content

[0004] The purpose of this application is to provide an eight-output KU-band high-frequency head structure to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this application discloses the following technical solution: an eight-output KU-band LNB structure, comprising a plastic upper cover, a plastic lower cover, a KU-band LNB assembly, a pull sleeve, and a waterproof cap; the plastic upper cover and the plastic lower cover are respectively disposed above and below the KU-band LNB assembly;

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] In this document, the term "comprising" is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0028] This embodiment discloses an eight-output KU-band LNB structure, combined with... Figure 1 and Figure 2 As shown, it includes a plastic upper cover 1, a plastic lower cover 2, a Ku-band LNB assembly 3, a pull sleeve 4, and a waterproof cap 5. The plastic upper cover 1 and the plastic lower cover 2 are respectively located above and below the Ku-band LNB assembly 3, and the plastic upper cover 1 and the plastic lower cover 2 are fastened together to cover the Ku-band LNB assembly 3.

[0029] In this embodiment, as Figure 3 As shown, the KU-band high-frequency head assembly 3 includes a waveguide body 31, a PCB board 32, a polarization probe 33, a shielding cover 34, an F-head 35, a cover plate 36, and a waveguide port 37.

[0030] The waveguide body 31 can be any of the existing technologies. It has a waveguide cavity inside and eight F-head holes are provided on the waveguide body 31. The eight F-heads 35 are installed in the F-head holes one by one. The waveguide body 31 is provided with a mounting groove, and the PCB board 32 is placed in the mounting groove. All eight F-heads 35 are connected to the PCB board 32.

[0031] One end of a pair of polarization probes 33 is soldered to the PCB board 32, and the other end extends into the waveguide cavity of the waveguide body 31.

[0032] The shielding cover 34 can be any type of metal shielding cover in the prior art. The shielding cover 34 is connected to the waveguide body 31, and the PCB board 32 is disposed between the shielding cover 34 and the waveguide body 31. Specifically, the shielding cover 34 is locked to the PCB board 32 and the waveguide body 31 by self-tapping screws 39. The PCB board 32 is also locked to the waveguide body 31 by self-tapping screws 39.

[0033] The cover plate 36 is connected to the waveguide body 31, and the shielding cover 34 and PCB board 32 are disposed between the cover plate 36 and the waveguide body 31. The cover plate 36 is made of galvanized sheet, and it is connected to the waveguide body 31 with waterproof adhesive to achieve waterproofing.

[0034] A waveguide port 37 is disposed on the waveguide body 31, and a waterproof cap 5 is fitted onto the waveguide port 37. Both the waveguide port 37 and the waterproof cap 5 are any of the prior art, and the waterproof cap 5 is used to achieve waterproof treatment of the waveguide port 37.

[0035] The pull sleeve 4 has through holes corresponding to eight F-heads 35. The eight F-heads 35 pass through the pull sleeve 4 through the through holes, and the pull sleeve 4 is slidably connected to the ends of the plastic upper cover 1 and plastic lower cover 2 near the F-heads 35, i.e. Figure 1 As shown, the pull sleeve 4 is fitted onto the output side of the entire high-frequency head structure (i.e., the side where the F-head 35 is located). It should be noted that the plastic upper cover 1 and the plastic lower cover 2 constitute the outer shell of the entire high-frequency head structure. The sliding connection between the pull sleeve 4 and the outer shell can employ any existing technology. Specifically, corresponding limiting protrusions can be provided on the connection surface between the pull sleeve 4 and the outer shell. The purpose of these protrusions is to limit the sliding distance of the pull sleeve 4 on the outer shell, preventing it from detaching from the shell. Furthermore, when waterproofing is required, such as for rain protection, the pull sleeve 4 can be pulled to cover the exposed F-head 35, thereby achieving waterproofing of the output side of the high-frequency head junction and ensuring the reliability and practicality of the high-frequency head structure.

[0036] As a preferred embodiment of this invention, in order to reduce the overall volume of the high-frequency head structure, in this embodiment, such as Figure 3As shown, the eight F-heads 35 are arranged in two rows, four on each side. The PCB board 32 has four connecting pins 38. The four F-heads 35 closest to the PCB board 32 are soldered to the PCB board 32, and the other four F-heads 35 are connected to the four connecting pins 38 one by one.

[0037] Working principle: The KU-band LNB assembly 3 receives the satellite TV signal focused by the antenna at its waveguide port 37 and transmits it to the polarization probe 33 through the waveguide cavity. The polarization probe 33 then transmits the signal to the PCB board 32, where the PCB board 32 amplifies, mixes, and performs intermediate frequency amplification on the signal before outputting it directly or via the connecting pin 38 to the F-type connector 35. The shielding cover 34 shields against external interference, and the cover plate 36 protects the PCB board 32 from dust and water. After the entire LNB structure is adjusted and the cables are connected, the pull sleeve 4 is pulled outwards to cover the F-type connector 35, thus protecting the F-type connector 35 from rain and providing waterproof protection for the waveguide port 37 via the waterproof cap 5.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
