DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0021] Example
[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a novel power synthesis coupler technical solution: including a coupler upper cavity 12 and a coupler lower cavity 11, wherein a continuous and closed coupling cavity is formed between the coupler lower cavity 11 and the coupler upper cavity 12 to ensure the continuity and stability of signal transmission. The ends of the coupler lower cavity 11 and the coupler upper cavity 12 are both provided with an outer frame 13 to enhance the overall structural strength and stability.
[0023] The top of the coupler upper cavity 12 is provided with a coupler upper plate seat 21, which is made of high thermal conductivity material to improve heat dissipation efficiency. On the upper plate seat, multiple groups of N-type connectors 23 are installed to facilitate connection with other devices or systems.
[0024] The synthesis component is located at the end of the outer frame 13. The synthesis component includes a synthesis cavity 31, which has a through opening 311, which is connected to the coupling cavity, so that the signal after coupling processing can smoothly enter the synthesis cavity for synthesis processing.
[0025] A synthesizer upper plate 32 is installed on the front of the synthesizer cavity 31, and a synthesizer cavity is separated between the upper plate and the cavity for completing the signal synthesis operation. A plurality of N-type connectors 34 are arranged on the synthesizer upper plate 32 for connecting with external devices or systems to realize signal input and output.
[0026] In order to improve the heat dissipation efficiency, heat dissipation fins 33 are installed on the opposite outer walls of the synthesizer cavity 31 and the synthesizer upper plate 32. These heat dissipation fins are made of high thermal conductivity materials and have a large surface area, which can effectively dissipate the heat generated inside to the external environment, thereby maintaining the operating temperature of the synthesizer within a suitable range.
[0027] In addition, in order to achieve precise adjustment of the amplitude and phase of the synthesized signal, a tuning column 35 is installed on each N-type connector 2 34. By adjusting the position and length of the tuning column, the transmission path and phase difference of the signal in the synthesizer can be changed, thereby achieving precise adjustment of the synthesized signal. At the same time, a tuning column connecting seat 37 that matches the tuning column is also provided on the synthesizer cavity 31 to ensure the stability and reliability of the tuning column.
[0028] In the synthesizer cavity, multiple synthesis connection blocks 36 are arranged at the edge of the through opening 311. These connection blocks are arranged in an array and are used to connect multiple signal channels to achieve signal synthesis. The design of the connection block takes into account the transmission characteristics and mechanical strength requirements of the signal to ensure the stability and reliability of the signal during the synthesis process.
[0029] The new power synthesis coupler provided by the utility model realizes the integration of signal coupling and synthesis functions by optimizing the structural design, reduces the overall volume, and is convenient for application in systems with limited space. At the same time, by adopting designs such as heat dissipation fins and adjustment columns, the overall heat dissipation efficiency and signal adjustment accuracy are improved, meeting the application requirements of high power and high performance. It has the advantages of small size, high heat dissipation efficiency, high signal adjustment accuracy, etc., and is suitable for various systems requiring high power and high performance signal processing.
[0030] The working principle and use process of the utility model: when in use, firstly, the multi-channel microwave signals to be synthesized are connected to the coupling cavity formed by the coupler upper cavity 12 and the coupler lower cavity 11 through the N-type connector 1 23. In the coupling cavity, the signal is guided by the coupler upper plate seat 21 and enters the through-port 311 of the synthesizer cavity 31. Next, the signal is connected and transmitted through the synthesis connection block 36 in the synthesizer cavity 31 to realize the synthesis of multi-channel signals. In the synthesis process, the heat dissipation fins 33 play a key role. They can effectively dissipate the heat generated inside the synthesizer to the external environment, keep the working temperature of the synthesizer within a suitable range, and avoid the internal temperature from being too high to affect the performance and service life. At the same time, by adjusting the position and length of the deployment column 35 on each N-type connector 2 34, the amplitude and phase of the synthesized signal can be accurately adjusted. This adjustment process can be flexibly operated according to actual needs to achieve the best signal synthesis effect. The synthesized and adjusted signal is output through the N-type connector 2 34 on the synthesizer upper plate 32 for use by other devices or systems.
[0031] During the entire working process, the new power synthesis coupler provided by the utility model realizes high-power and high-performance signal synthesis processing through its compact structural design, efficient heat dissipation performance and precise signal adjustment function, meeting the needs of various complex application scenarios.
