[0002] Ku-band (KU) power amplifier modules operate in the Ku-band (12-18GHz) and their main function is to amplify weak input radio frequency signals to the required power level. They are widely used in satellite communications, radar systems, and wireless communications. Their core features include high gain, high efficiency, wide bandwidth, and high linearity, which reduce distortion during signal amplification and ensure communication quality. They typically employ advanced devices such as gallium nitride (GaN) to enhance performance and can adapt to the power requirements of different scenarios, such as uplink signal amplification in satellite ground stations and detection signal transmission in radar systems, providing stable high-power signal output support for various electronic systems.

[0003] However, the current KU power amplifier modules have the following defects: First, the output gain is fixed, making it difficult to adapt to the signal requirements of different scenarios and unable to be flexibly adjusted to match the transmission distance or strong and weak signal environment; Second, the protection and heat dissipation design is insufficient, making them easy to be damaged by external impacts, and the heat dissipation effect is poor, affecting stability and lifespan. In response to this technical problem, this application proposes a KU power amplifier module with an adjustment structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a KU power amplifier module with an adjustable structure. This module aims to adjust the output gain of the power amplifier module to adapt to the signal requirements of different scenarios, protect the power amplifier module from damage caused by external impacts, and provide heat dissipation for the power amplifier module.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A KU power amplifier module with an adjustable structure includes a base, on which the power amplifier module is mounted. A groove is formed on the right side of the power amplifier module, and an adjustment component is disposed inside the groove. The output gain of the power amplifier module is adjusted by the adjustment component. A first protective shell is fixedly connected to the top side of the base, and a second protective shell is connected to the top side of the first protective shell via a fixing component to fix the second protective shell onto the first protective shell. A through slot is formed in the middle of the base, and a heat dissipation component is disposed inside the through slot to provide heat dissipation for the power amplifier module.

[0007] Furthermore, a probe is fixedly connected to the left side of the slider, and a ceramic patch attenuator is fixedly connected inside the groove. The end of the probe and the right side of the ceramic patch attenuator are attached to each other.

[0008] Furthermore, a cable is fixedly connected to the right side of the slider, and a knob is rotatably connected to the front side of the power amplifier module via a damping shaft, with the front end of the threaded rod fixedly connected inside the knob.

[0009] Furthermore, the fixing assembly includes four metal plates fixedly connected to the front and rear sides of the first protective shell, with a buckle plate connecting two adjacent metal plates via a torsion spring, and two fixing plates fixedly connected to the front and rear sides of the second protective shell.

[0010] Furthermore, a fixing rod is inserted into the top side of the buckle plate, and the fixing rod passes through the middle of the fixing plate.

[0011] Furthermore, the heat dissipation assembly includes honeycomb-shaped heat dissipation fins fixedly connected inside the through slot, and thermally conductive silicone is fixedly connected to the top side of the honeycomb-shaped heat dissipation fins.

[0017] 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.

[0018] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a KU power amplifier module with an adjustable structure, including a base 1. A power amplifier module 11 is mounted on the top side of the base 1. A groove is formed on the right side of the power amplifier module 11. A first protective shell 2 is fixedly connected to the top side of the base 1, and a second protective shell 6 is connected to the top side of the first protective shell 2. The first and second protective shells 2 form a closed space to protect the power amplifier module 11 from damage caused by impacts from external objects. A through groove is formed in the middle of the base 1. Figure 4 and Figure 6A slider 13 is slidably connected inside the groove, and a threaded rod 12 is rotatably connected inside the groove. The slider 13 is threaded onto the outer wall of the threaded rod 12. A probe 16 is fixedly connected to the left side of the slider 13. A ceramic patch attenuator 17 is fixedly connected inside the groove, and the end of the probe 16 is in contact with the right side of the ceramic patch attenuator 17. A cable 4 is fixedly connected to the right side of the slider 13. A knob 3 is rotatably connected to the front of the power amplifier module 11 via a damping shaft. The front end of the threaded rod 12 is fixedly connected inside the knob 3. Rotating the knob 3 causes the threaded rod 12 to rotate, which in turn drives the slider 13 to slide, allowing the slider 13 to move along the surface of the ceramic patch attenuator 17 with the probe 16. The principle is as follows: When slider 13 slides, probe 16 contacts different positions of ceramic patch attenuator 17, thereby changing the length of ceramic patch attenuator 17 connected to the circuit. The longer the connection length, the greater the attenuation of the signal, and the lower the output gain of power amplifier module 11; the shorter the connection length, the smaller the attenuation, and the higher the output gain. For example: Assuming the initial gain of the module is 40dB: When it is necessary to reduce the gain by 5dB, the operator drives slider 13 to slide backward by 3.3mm. At this time, probe 16 of slider 13 contacts a 3.3mm section of ceramic patch attenuator 17. This section of ceramic patch attenuator 17 will attenuate the input signal by 5dB, and the module output gain becomes 35dB. If slider 13 is further slid to the 6.7mm position, the length of the connected ceramic patch attenuator 17 increases, the signal attenuation increases to 10dB, and the output gain of power amplifier module 11 drops to 30dB. When slider 13 slides to its maximum travel of 10mm, the entire effective area of ​​ceramic patch attenuator 17 is connected to the circuit, the attenuation reaches 15dB, and the output gain of power amplifier module 11 drops to the minimum value of 25dB.

[0019] Reference Figure 1 , Figure 2 and Figure 5Four metal plates 7 are fixedly connected to the front and rear sides of the first protective shell 2. A buckle plate 8 is connected between two adjacent metal plates 7 by a torsion spring. Two fixing plates 9 are fixedly connected to the front and rear sides of the second protective shell 6. A fixing rod 10 is inserted into the top side of the buckle plate 8 and passes through the middle of the fixing plate 9. By rotating the buckle plate 8, its top side is rotated to the top side of the fixing plate 9. Then, the fixing rod 10 is inserted into the bottom side of the buckle plate 8 and the fixing plate 9 to fix the buckle plate 8 to the fixing plate 9, thereby fixing the second protective shell 6 to the first protective shell 2. A honeycomb heat dissipation fin 15 is fixedly connected inside the through groove. A thermally conductive silicone 14 is fixedly connected to the top side of the honeycomb heat dissipation fin 15. The thermally conductive silicone 14 conducts the heat of the power amplifier module 11 to the honeycomb heat dissipation fin 15, thereby dissipating the heat through the honeycomb heat dissipation fin 15, thus providing a heat dissipation effect for the power amplifier module 11. At the same time, holes can be opened on the outer walls of the first protective shell 2 and the second protective shell 6 as needed to further improve the heat dissipation effect. Rubber strips 5 are fixedly connected to the right side of both the first protective shell 2 and the second protective shell 6. The two rubber strips 5 are in contact with each other. The working principle of the rubber strips 5 is as follows: when the slider 13 moves to a certain position, the rubber strip 5 will be stretched open by the cable 4 due to its own elasticity, so that the slider 13 can move normally. When the slider 13 moves to another position, the rubber strip 5 will automatically close due to its own elasticity. The above action is repeated at other positions, thus providing protection for the threaded rod 12 and preventing dirt from affecting it.

[0020] Working principle: First, install the power amplifier module 11 onto the base 1 and ensure it adheres to the thermally conductive silicone 14. Then, place the second protective shell 6 onto the first protective shell 2. Next, rotate the latching plate 8 so that its top side is aligned with the top side of the fixing plate 9. Then, insert the fixing rod 10 into the bottom side of the latching plate 8 and the fixing plate 9 to fix the latching plate 8 onto the fixing plate 9, thereby fixing the second protective shell 6 onto the first protective shell 2. Then, adjust the output gain of the power amplifier module 11 as needed. When adjustment is required, rotate the knob 3 to adjust the threaded rod. Rotation of 12 causes the threaded rod 12 to drive the slider 13 to slide, causing the slider 13 to move along the surface of the ceramic patch attenuator 17 with the probe 16, thereby adjusting the output gain of the power amplifier module 11. The specific adjustment principle has been explained above and will not be repeated here. During the operation of the power amplifier module 11, the heat of the power amplifier module 11 is conducted to the honeycomb heat dissipation fins 15 through the thermally conductive silicone 14, and the heat is dissipated through the honeycomb heat dissipation fins 15, thereby providing a heat dissipation effect for the power amplifier module 11.

[0021] 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.
