Description

Technical Field

[0001] The utility model belongs to the field of isolators, and specifically relates to an anti-reflection ultra-wideband stripline isolator. Background Art

[0002] A stripline isolator is a device used to isolate electrical signals between different parts of a circuit. An ultra-wideband stripline isolator is a device that combines ultra-wideband communication technology and line isolation function. It can transmit ultra-wideband signals from one circuit to another while providing electrical isolation to prevent the influence of electrical interference and ground loop problems.

[0003] Ultra-wideband stripline isolators usually need to be used in combination with other electrical components. During the use process, they are inevitably interfered by signal waves from other electrical components. The reflection of signal waves will cause the performance of the isolator to decline, including problems such as increased signal attenuation, interference, and reduced signal quality, thereby affecting the stability, reliability, and performance of the isolator.

[0004] In summary, the utility model provides an anti-reflection ultra-wideband stripline isolator to solve the above problems. Content of the Utility Model

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

[0006] An anti-reflection ultra-wideband stripline isolator, including a box body. The number of the box bodies is two. An installation mechanism is arranged on the surface of the box body. A temperature compensator is arranged at the bottom of the inner cavity of the lower box body. A central waveguide is arranged between the two box bodies and above the temperature compensator. Rotating ferrites are arranged at the top and bottom of the central waveguide. A metal substrate is arranged at one end of the rotating ferrite away from the central waveguide.

[0007] The installation mechanism includes a first fixing column. The first fixing column is located around the upper box body and is fixedly connected to it. Second fixing columns are fixedly connected to the four sides of the lower box body. Protective sleeves are fixedly connected to the surfaces of the first fixing column and the second fixing column.

[0008] Further, an installation groove is opened at the bottom of the first fixing column. An installation column is fixedly connected to the top of the second fixing column. The top of the installation column extends into the inner cavity of the installation groove and is detachably connected to the inner cavity of the installation groove.

[0009] Further, a bolt is arranged at the top of the first fixing column. The bottom of the bolt extends into the inner cavity of the installation column and is threadedly connected to the inner cavity of the installation column.

[0010] Furthermore, a permanent magnet is provided at one end of the metal substrate away from the rotating ferrite. An absorbing load is provided on the front surface of the rotating ferrite. The central waveguide includes a first port and a second port. The first port is located on the left side of the central waveguide, and the second port is located on the right side of the box body.

[0011] Furthermore, the two rotating ferrites, metal substrates, permanent magnets, and absorbing loads located at the top and bottom of the central waveguide are all symmetrically distributed.

[0012] Furthermore, the periphery and bottom of the temperature compensator are fixedly connected to the inner wall of the box body.

[0013] Beneficial effects: The present utility model has the following beneficial effects:

[0014] By providing the box body, the present utility model can provide a sealed placement space for the internal components, increasing the safety of each component during use. At the same time, since the two box bodies are connected by the installation mechanism, the two box bodies can be disassembled through the installation mechanism to facilitate the maintenance or replacement of the components inside the box body. By providing the temperature compensator, it is used to adjust or offset the performance changes of the internal components of the box body under temperature changes, preventing the components from being negatively affected by the working temperature changes on their performance. By providing the central waveguide, rotating ferrite, metal substrate, permanent magnet, and absorbing load, they are used to form the isolator body. Since the isolation bandwidth exceeds one octave, and this isolator is different from the ring isolator, due to its side-guide effect, the reverse-transmitted microwave signal enters from the second port and then propagates along the edge of the central waveguide to the second port, and the signal wave is absorbed and attenuated by the absorbing load, thereby achieving the isolation of the reverse signal wave, thus preventing the situation where the reflection of the signal wave causes the performance of the isolator to decline, affecting the stability, reliability, and performance of the isolator.

[0024] The mounting mechanism 2 includes a first fixing column 201, the first fixing column 201 is located around the upper box body 1 and is fixedly connected thereto, second fixing columns 202 are fixedly connected to the periphery of the lower box body 1, and protective sleeves 203 are fixedly connected to the surfaces of the first fixing column 201 and the second fixing column 202.

[0025] As Figures 1-4As shown, the box body 1 can provide a sealed placement space for the internal components, increasing the safety of each component during use. The temperature compensator 3 is used to adjust or offset the performance changes of the internal components of the box body 1 under temperature changes, preventing the components from being negatively affected by the working temperature change on their performance. The center waveguide 4, the rotating ferrite 5, the metal substrate 6, the permanent magnet 7, and the absorbing load 8 are used to form the isolator body. Since the isolation bandwidth exceeds one octave, and this isolator is different from the ring isolator, due to its side guide effect, the backward transmitted microwave signal enters from the second port 42, and then propagates along the edge of the center waveguide 4 to the second port 42. The signal wave is absorbed and attenuated by the absorbing load, so as to achieve the isolation of the backward signal wave, thereby preventing the situation that the reflection of the signal wave causes the performance of the isolator to decline, affecting the stability, reliability, and performance of the isolator.

[0026] Embodiment 2

[0027] Referring to Figure 4 , this is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0030] As Figure 4 shown, by inserting the installation column 205 into the installation groove 204 and using bolts to fix the installation column 205 inside the installation groove 204, the two box bodies 1 can be fixed.

[0031] Embodiment 3

[0032] Referring to Figure 3 , this is the third embodiment of the present utility model, and this embodiment is based on the previous two embodiments.

[0033] In this embodiment, a permanent magnet 7 is provided at one end of the metal substrate 6 away from the rotating ferrite 5, an absorbing load 8 is provided on the front surface of the rotating ferrite 5, the center waveguide 4 includes a first port 41 and a second port 42, the first port 41 is located on the left side of the center waveguide 4, and the second port 42 is located on the right side of the box body 1.

[0035] The periphery and bottom of the temperature compensator 3 are fixedly connected to the inner wall of the box body 1.

The signal wave is absorbed and attenuated by the absorbing load, so as to achieve the isolation of the backward signal wave. The temperature compensator 3 is used to adjust or offset the performance change of the internal components of the box body 1 under temperature change, and prevent the components from being negatively affected by the working temperature change on their performance.

[0037] During use, the box body 1 can provide a sealed placement space for the internal components, improving the safety of each component during use. The temperature compensator 3 is used to adjust or offset the performance change of the internal components of the box body 1 under temperature change, and prevent the components from being negatively affected by the working temperature change on their performance. The central waveguide 4, the rotating ferrite 5, the metal substrate 6, the permanent magnet 7 and the absorbing load 8 are used to form the isolator body. Since the isolation bandwidth is more than one octave, and this isolator is different from the ring isolator because of its side-guide effect, the backward-transmitted microwave signal enters from the second port 42, and then propagates along the edge of the central waveguide 4 to the second port 42. The signal wave is absorbed and attenuated by the absorbing load, so as to achieve the isolation of the backward signal wave, thereby preventing the reflection of the signal wave from causing a decrease in the performance of the isolator, affecting the stability, reliability and performance of the isolator.
