Technical Field

[0001] This utility model relates to the field of microwave technology, and in particular to a microwave transmitter module.

[0002] Background technology.

[0003] In many fields such as modern communications, radar detection, and industrial microwave applications, microwave transmitters are key equipment, and their performance directly affects the operation of the entire system.

[0004] As the core component of a microwave transmitter, the microwave transmitter module carries a series of key functions such as signal generation, processing, and transmission, and is a crucial structure to ensure that the performance of the microwave transmitter can be fully utilized.

[0005] However, in complex electromagnetic environments, various sources of electromagnetic interference are ubiquitous. For example, in densely populated urban communication base station areas, signals of different frequency bands intertwine, and the chaotic electromagnetic radiation generated by a large number of electronic devices severely interferes with the transmission and processing of signals inside the microwave transmitter module. Without effective shielding measures, low-frequency magnetic fields can easily affect signal stability, leading to signal distortion; high-frequency electric fields can cause internal circuits to malfunction, greatly reducing the reliability and accuracy of the microwave transmitter. Furthermore, microwave transmitter modules need to be compatible with microwave oscillators of different specifications to meet diverse application scenarios, and traditional modules are difficult to install microwave oscillators of different lengths quickly and easily.

[0006] Therefore, a microwave transmitter module is provided to solve the problems mentioned in the background art. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a microwave transmitter module, comprising a metal housing, an inner base plate, an L-shaped plate, and fixing bolts on the base plate; a plurality of positioning holes on the upper side of the base plate; a transmitting assembly on the base plate; an antenna mounted on the right side of the metal housing; a mounting assembly on the front side of the metal housing; an inner shielding layer installed inside the metal housing; an outer shielding layer inside the inner shielding layer; heat dissipation fins mounted on the upper side of the metal housing; and a cooling fan installed inside the metal housing.

[0009] Furthermore, the transmitting assembly includes a microwave oscillator mounted on a base plate, a modulator mounted on the front side of the microwave oscillator, and an amplifier mounted on the left side of the modulator.

[0010] Furthermore, the mounting assembly includes a mounting plate disposed on the front side of the metal housing, mounting bolts are disposed inside the mounting plate, and mounting holes are provided inside the metal housing.

[0011] Furthermore, the L-shaped plate is attached to the outer side of the microwave oscillator.

[0012] Furthermore, the fixing bolt is threadedly connected to the interior of the positioning hole.

[0013] Furthermore, the mounting bolt is threaded into the interior of the mounting hole.

[0014] Furthermore, the cooling fan is located on the rear side of the mounting plate.

[0015] Furthermore, the microwave oscillator, amplifier, modulator, and antenna are electrically connected.

[0016] This utility model has the following beneficial effects: In this invention, the coordinated operation of a microwave oscillator, amplifier, modulator, and antenna realizes a complete process from signal generation, amplification, modulation to transmission, efficiently completing the wireless transmission of information and meeting the signal transmission requirements of various application scenarios such as communication and detection.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 , Figure 2 and Figure 6 An embodiment of this utility model provides a microwave transmitter module, including a metal housing 1, a base plate 2 inside the metal housing 1, a transmitting assembly 3 on the base plate 2, the transmitting assembly 3 including a microwave oscillator 31, the microwave oscillator 31 being disposed on the base plate 2, a modulator 33 being mounted on the front side of the microwave oscillator 31, an amplifier 32 being mounted on the left side of the modulator 33, an L-shaped plate 4 being attached to the outer side of the microwave oscillator 31, and the microwave oscillator 31, amplifier 32, modulator 33 and antenna 12 being electrically connected, an inner shielding layer 10 being installed inside the metal housing 1, an outer shielding layer 11 being disposed inside the inner shielding layer 10, heat dissipation fins 7 being mounted on the upper side of the metal housing 1, a cooling fan 8 being installed inside the metal housing 1, and the cooling fan 8 being disposed on the rear side of the mounting plate 93; Specifically, an initial microwave signal is generated by a microwave oscillator 31 inside the metal casing 1. This signal is then transmitted forward to an amplifier 32, which amplifies the weak signal output from the microwave oscillator 31, significantly increasing the signal strength to meet the requirements of subsequent signal transmission and processing. The amplified signal is then sent to a modulator 33, which loads the pre-prepared information to be transmitted onto the microwave signal, completing the modulation process. The modulated signal is then transmitted to the antenna 12 via a specific circuit connection. The antenna 12 undertakes the transmission task, transmitting the information-carrying microwave signal into outer space. The inner shielding layer 10 inside the housing 1 is made of a high-permeability material, such as permalloy, mainly used to shield low-frequency magnetic fields and reduce the interference of low-frequency magnetic fields on the internal signal transmission and processing of the module. The outer shielding layer 11 is made of a high-conductivity material, such as copper, used to shield high-frequency electric fields and further reduce the influence of external high-frequency electric fields on the module, ensuring that the internal components of the module work in a relatively stable electromagnetic environment. When the internal components of the module overheat due to long-term operation, the cooling fan 8 starts, and together with the heat dissipation fins 7 installed on the upper side of the metal housing 1, the heat generated during the operation of the module is quickly dissipated to the surrounding environment, ensuring that the temperature of the module is maintained within a suitable range and avoiding performance degradation or component damage due to overheating.

[0022] Reference Figure 3 , Figure 4 and Figure 5 An L-shaped plate 4 is provided on the base plate 2, and a fixing bolt 5 is provided on the L-shaped plate 4. Several positioning holes 6 are opened on the upper side of the base plate 2. The fixing bolt 5 is threaded into the interior of the positioning holes 6. An antenna 12 is installed on the right side of the metal shell 1. An installation assembly 9 is provided on the front side of the metal shell 1. The installation assembly 9 includes an installation plate 93. The installation plate 93 is located on the front side of the metal shell 1. An installation bolt 91 is provided inside the installation plate 93. An installation hole 92 is opened inside the metal shell 1. The installation bolt 91 is threaded into the interior of the installation hole 92. Specifically, when it is necessary to perform maintenance and disassembly operations on the microwave oscillator 31, firstly, use the appropriate tools to rotate the mounting bolt 91 so that the mounting bolt 91 is disengaged from the mounting hole 92, thereby allowing the mounting plate 93 to be removed. Then, remove the base plate 2 from the metal housing 1. Next, rotate the fixing bolt 5 so that the L-shaped plate 4 is disengaged from the positioning hole 6, releasing the fixing constraint on the microwave oscillator 31, and then the microwave oscillator 31 can be subjected to subsequent maintenance. When it is necessary to install microwave oscillators 31 of different lengths, the fixing bolt 5 can be turned into the designated positioning hole 6 so that the L-shaped plate 4 can accurately clamp and limit the outside of the microwave oscillator 31, ensuring that microwave oscillators 31 of different specifications can be installed stably and meeting diverse usage needs.

[0023] Working Principle: When using this device, the microwave oscillator 31 generates an initial microwave signal, which is then transmitted to the amplifier 32 in front of it. The amplifier 32 amplifies the weak signal output by the microwave oscillator 31, increasing the signal strength. The amplified signal is then transmitted to the modulator 33, which loads the information to be transmitted onto the microwave signal, and finally transmits it to the antenna 12. The antenna 12 transmits the information-carrying microwave signal into the outside space, realizing wireless information transmission. The inner shielding layer 10 inside the metal casing 1 reduces the interference of low-frequency magnetic fields on the signal transmission and processing inside the module; the outer shielding layer 11 further reduces the influence of external high-frequency electric fields on the module, ensuring the internal signal transmission and processing of the module. The components operate in a relatively stable electromagnetic environment. When the internal components overheat, the cooling fan 8 is activated, and the heat dissipation fins 7 installed on the upper side of the metal casing 1 quickly dissipate the heat generated during module operation to the surrounding environment. When the microwave oscillator 31 needs to be repaired or disassembled, the mounting bolt 91 is first rotated with a tool to disengage it from the mounting hole 92, the mounting plate 93 is then removed, and the base plate 2 is taken out. By rotating the fixing bolt 5, the L-shaped plate 4 is disengaged from the positioning hole 6, thus releasing the fixation of the microwave oscillator 31. When it is necessary to install microwave oscillators 31 of different lengths, the fixing bolt 5 is rotated into the designated positioning hole 6, so that the L-shaped plate 4 clamps and limits the outer side of the microwave oscillator 31.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 the present utility model should be included within the protection scope of the present utility model.
