Description

Technical Field

[0001] The utility model relates to the technical field of attenuators, in particular to a high-frequency and high-power integrated attenuator. Background Art

[0002] An attenuator generally attenuates a large voltage signal to a certain proportional multiple (generally refers to power attenuation) to achieve a safe or ideal level value, which facilitates testing. It is especially widely used in RF and microwave. Its main purpose is to adjust the size of the signal in the circuit; when in the comparison circuit, the attenuation value of the network under test can be directly read; to improve impedance matching, when some circuits require a relatively stable load impedance, an attenuator can be inserted between the circuit and the actual load impedance to buffer the impedance changes.

[0003] In the prior art, with the continuous development of electronic technology and the diversification of electronic products, the frequency and power indicators of attenuators are required to be higher and higher, while the power of existing coaxial attenuators is not easy to adjust according to needs, so we have launched a high-frequency and high-power integrated attenuator. Utility Model Content

[0004] The purpose of the utility model is to provide a high-frequency and high-power integrated attenuator, which can not only adjust the power of the attenuator according to needs, but also significantly improve the power and frequency of the attenuator, thereby greatly improving the power bearing capacity of the attenuator to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-frequency and high-power integrated attenuator comprises a shell, an input end and an output end, wherein the input end is fixedly arranged at one end of the shell, the output end is fixedly arranged at the other end of the shell, connecting rods are fixedly arranged at opposite ends of the input end and the output end, opposite ends of the two connecting rods penetrate into the shell, a plurality of connecting blocks are arranged between the two connecting rods, the two connecting blocks located at the outermost sides are fixedly connected to the corresponding connecting rods, an integrated attenuation mechanism is arranged between the two adjacent connecting blocks, and the integrated attenuation mechanism can perform multi-section attenuation to improve the power bearing capacity of the attenuator.

[0007] Preferably, the integrated attenuation mechanism includes an adapter column, which is arranged between two adjacent connecting blocks, a connecting resistor rod is provided between the connecting block and the adapter column, and the side walls of the connecting block and the adapter column are both provided with a first mounting groove matching the connecting resistor rod.

[0008] Preferably, ground resistance rods are provided on both upper and lower sides of the adapter column, and second installation grooves matching with the ground resistance rods are provided on both upper and lower sides of the adapter column and the inner side wall of the shell.

[0009] Preferably, the groove walls of the first mounting groove and the second mounting groove are evenly provided with a plurality of limiting protrusions.

[0010] Preferably, a tightening sheet is fixedly provided at the bottom of each of the first mounting groove and the second mounting groove.

[0011] Preferably, the abutting sheet is an elastic metal sheet.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The high-frequency and high-power integrated attenuator is provided with an output end, a connecting rod, a transfer column, a ground resistance rod, a connecting block, an input end, a connecting resistance rod, a shell, a limiting protrusion, and a tightening sheet. The ground resistance rod adopts two parallel connections to form a symmetrical structure, which evenly distributes the heat dissipation and does not cause local overheating. When a large power is input, multiple sections of attenuation can be added, and each section of attenuation evenly distributes the power, which can greatly improve the power bearing capacity of the attenuator. Under the condition that the input and output standing waves of each section are good, the indicators of the input and output standing waves of the multi-section attenuation series are almost the same as the standing waves of the single-section attenuation. The attenuation accuracy of the attenuator is matched. The attenuation curve trend of the small attenuation value is a negative slope curve, and the trend of the attenuation curve of the large attenuation value is a positive slope. The superposition of these two can weaken each other's trend, so that the attenuation value of the entire attenuator tends to be gentle, further ensuring the attenuation index of the attenuator. Not only can the power of the attenuator be adjusted according to needs, but also the power and frequency of the attenuator can be significantly improved, which greatly improves the power bearing capacity of the attenuator.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 to Figure 2 , the utility model provides a technical solution:

[0019] A high-frequency and high-power integrated attenuator comprises a shell 8, an input terminal 6 and an output terminal 1, wherein the input terminal 6 is fixedly arranged at one end of the shell 8, and the output terminal 1 is fixedly arranged at the other end of the shell 8. Connecting rods 2 are fixedly arranged at opposite ends of the input terminal 6 and the output terminal 1, and opposite ends of the two connecting rods 2 penetrate into the shell 8. A plurality of connecting blocks 5 are arranged between the two connecting rods 2, and the two outermost connecting blocks 5 are fixedly connected to the corresponding connecting rods 2. An integrated attenuation mechanism is arranged between two adjacent connecting blocks 5, and the integrated attenuation mechanism can perform multi-section attenuation to improve the power bearing capacity of the attenuator.

[0020] The integrated attenuation mechanism includes an adapter column 3, which is arranged between two adjacent connecting blocks 5. A connecting resistor rod 7 is arranged between the connecting block 5 and the adapter column 3, and the side walls of the connecting block 5 and the adapter column 3 are both provided with a first mounting groove that matches the connecting resistor rod 7.

[0021] The upper and lower sides of the adapter column 3 are both provided with ground resistance rods 4 , and the upper and lower sides of the adapter column 3 and the inner side wall of the shell 8 are both provided with second installation grooves matched with the ground resistance rods 4 .

[0022] A plurality of limiting protrusions 9 are evenly arranged on the groove walls of the first installation groove and the second installation groove, and the limiting protrusions 9 can clamp the resistor rod.

[0023] A clamping sheet 10 is fixedly disposed at the bottom of the first installation slot and the second installation slot. The clamping sheet 10 is an elastic metal sheet and is convenient for clamping the resistor rod.

[0024] When in use, two ground resistance rods 4 are connected in parallel to form a symmetrical structure, which evenly distributes heat dissipation and does not cause local overheating. When high power is input, multiple attenuation sections can be added, and each attenuation section evenly distributes power, which can greatly improve the power bearing capacity of the attenuator. Under the condition that the input and output standing waves of each section are guaranteed to be good, the indicators of the input and output standing waves of the multi-section attenuation series are almost the same as the standing waves of the single-section attenuation. The attenuation accuracy of the attenuator is matched, and the attenuation curve trend of the small attenuation value is a negative slope curve, and the trend of the attenuation curve of the large attenuation value is a positive slope. These two superpositions can weaken each other's trends, making the attenuation value of the entire attenuator tend to be gentle, further ensuring the attenuation index of the attenuator.
