Description

Technical Field

[0001] The utility model belongs to the field of radio frequency technology, and particularly relates to a radio frequency module. Background Art

[0002] RF modules usually need to be equipped with a shielding cover to improve their ability to resist external interference. The height of the shielding cover and the distance between the components on the RF module and the shielding cover will affect the resistance, capacitance and inductance characteristics inside the components, thereby affecting the performance of the components and the performance of the RF module.

[0003] The existing shielding covers are divided into one-piece shielding covers and two-piece shielding covers. During the RF testing process of the RF module, since both the one-piece shielding cover and the two-piece shielding cover are integrated shielding covers and the height of a single shielding cover is fixed, if it is found that the RF performance of the RF module is affected by the shielding cover, it is difficult to locate the affected components.

[0027] 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 of 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.

[0028] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0030] like Figure 1 and Figure 2As shown, the RF module provided in the embodiment of the utility model includes a RF module 1 and a shielding cover 2. The RF module 1 is provided with components 11. The shielding cover 2 is installed on the RF module 1 and can shield the components 11. Specifically, the shielding cover 2 is welded to the contact surface of GND 12 on the RF module 1 to achieve grounding.

[0031] The shielding cover 2 can be deformed so that a position on the shielding cover 2 opposite to the component 11 along the height direction is moved closer to or farther away from the component 11 , so as to adjust the distance between the shielding cover 2 and the component 11 along the height direction.

[0032] The RF module provided by the embodiment of the utility model deforms the shielding cover 2 so that the position on the shielding cover 2 that is opposite to the component 11 along the height direction is closer to or farther away from the component 11, thereby adjusting the distance between the shielding cover 2 and the component 11 along the height direction. When performing RF testing, if it is found that the RF performance of the RF module is affected by the shielding cover 2, pressure can be applied to the shielding cover 2 to move away from the component 11, so that the shielding cover 2 is deformed and the position on the shielding cover 2 that is opposite to the component 11 along the height direction is away from the component 11, thereby increasing the distance between the shielding cover 2 and the component 11 along the height direction. At this time, if it is found that the RF performance is restored, the component 11 below this position is the originally affected component 11.

[0033] In the embodiment of the utility model, "RF performance recovery" means that after the shielding cover 2 is away from the component 11, when the RF module is tested again, the result of the re-RF test shows that the RF performance is no longer affected by the shielding cover 2, that is, the result of the re-RF test shows that the RF indicators of the RF module meet the preset standards. In one embodiment, the shielding cover 2 is made of copper foil to ensure the deformation of the shielding cover 2.

[0034] In one embodiment, when the position of the shielding cover 2 opposite to the component 11 along the height direction is close to the component 11 , the distance between the shielding cover 2 and the component 11 along the height direction is reduced.

[0035] When the position of the shielding cover 2 opposite to the component 11 along the height direction is away from the component 11 , the distance between the shielding cover 2 and the component 11 along the height direction increases.

[0036] When the distance between the shielding cover 2 and the component 11 along the height direction increases, if it is found that the radio frequency performance is restored at this time, the component 11 below this position is the affected component 11.

[0037] In one embodiment, if Figure 1 and Figure 2 As shown, the shielding cover 2 may be deformed as a whole, that is, not only the position of the shielding cover 2 that is opposite to the component 11 along the height direction is deformed, but also the position of the shielding cover 2 that is not opposite to the component 11 along the height direction is deformed. Alternatively, the shielding cover 2 may be partially deformed, that is, the position of the shielding cover 2 that is opposite to the component 11 along the height direction is deformed, or the position of the shielding cover 2 that is not opposite to the component 11 along the height direction is deformed.

[0038] Specifically, the shielding cover 2 may include a first shielding area 21 and a second shielding area 22, wherein the first shielding area 21 is arranged opposite to the component 11 in the height direction, the second shielding area 22 is arranged around the first shielding area 21, and the second shielding area 22 is connected between the first shielding area 21 and the RF module 1. The first shielding area 21 and / or the second shielding area 22 may be deformed so that the first shielding area 21 is close to or away from the component 11. It can be understood that when both the first shielding area 21 and the second shielding area 22 are deformed, the shielding cover 2 is deformed as a whole. When the first shielding area 21 or the second shielding area 22 is deformed, that is, when one of the first shielding area 21 and the second shielding area 22 is deformed, the shielding cover 2 is partially deformed.

[0039] Further, the first shielding area 21 may be convexly deformed in a direction away from the component 11, so that the first shielding area 21 is away from the component 11. Alternatively, the first shielding area 21 may be concavely deformed in a direction close to the component 11, so that the first shielding area 21 is close to the component 11.

[0040] The second shielding area 22 may be stretched and deformed in a direction away from the component 11, so that the first shielding area 21 is away from the component. Alternatively, the second shielding area 22 may be bent and deformed in a direction close to the component, so that the first shielding area 21 is close to the component.

[0041] In one embodiment, the region on the shielding cover 2 where deformation occurs (the first shielding region 21 and / or the second shielding region 22 ) may be formed with wrinkles to increase the deformation amount of the shielding cover.

[0042] In one embodiment, there are multiple components 11 and multiple shielding covers 2, and the multiple shielding covers 2 are arranged one-to-one with the multiple components 11. At this time, if it is found that the RF performance of the RF module is affected by the shielding cover 2, the shielding covers 2 are deformed in turn to find the affected components.

[0043] In one embodiment, a plurality of components 11 are provided, and at least one shielding cover 2 is provided. Each shielding cover 2 is provided corresponding to one or more components 11 , and each component 11 is provided corresponding to only one shielding cover 2 .

[0044] Specifically, "at least one shielding cover 2 is provided, and each shielding cover 2 is respectively provided corresponding to one or more components 11" includes three situations: the first is that the shielding cover 2 is provided with one, in this case, a single shielding cover 2 corresponds to a plurality of components 11, and a single shielding cover 2 can shield all of the plurality of components 11, and the affected components can be found by adjusting the height of the position on the shielding cover 2 relative to each component 11 respectively; the second is that a plurality of shielding covers 2 are provided, and each shielding cover 2 is provided corresponding to a plurality of components 11, in this case, the position on each shielding cover 2 relative to each corresponding component 11 can be deformed to be close to or away from the component 11; the third (such as Figure 1 and Figure 2 As shown in the figure, there are multiple shielding covers 2, some of the shielding covers 2 are arranged in a one-to-one correspondence with some of the components 11, and among the remaining shielding covers 2 and the remaining components 11, each shielding cover 2 is arranged in correspondence with multiple components 11, and the position of each shielding cover 2 relative to each component 11 can be deformed to approach or move away from the component 11.

[0045] The fewer the number of components 11 corresponding to a single shielding cover 2 is, the easier it is to find the affected components 11 .

[0046] The present invention is described below with reference to specific embodiments:

[0047] like Figure 1 and Figure 2In the illustrated embodiment, the RF module 1 is provided with three components 11, which are respectively marked as a first component 11a, a second component 11b, and a third component 11c. Two shielding covers 2 are provided, which are respectively marked as a first shielding cover 2a and a second shielding cover 2b. The first shielding cover 2a is used to shield the first component 11a, and the second shielding cover 2b is used to shield the second component 11b and the third component 11c. It should be noted that Figure 1 and Figure 2 The dotted line with an arrow in the figure represents the signal radiation path of the corresponding component 11.

[0048] When it is found that the RF performance of the RF module is affected by the shielding cover 2, such as Figure 2 As shown, the first shielding area 21 of the first shielding cover 2a is deformed in a direction away from the first component 11a to increase the distance between the first shielding cover 2a and the first component 11a along the height direction. If the RF performance is found to be restored at this time, the first component 11a is the originally affected component 11.

[0049] Furthermore, the position relative to the second component 11b in the first shielding area 21 of the second shielding cover 2b is deformed in a direction away from the second component 11b to increase the distance between the second shielding cover 2b and the second component 11b along the height direction. If it is found that the RF performance remains unchanged at this time, it can be known that the second component 11b is not affected.

[0050] The position opposite to the third component 11c in the first shielding area 21 of the second shielding cover 2b is deformed in a direction away from the third component 11c to increase the distance between the second shielding cover 2b and the third component 11c along the height direction. If the RF performance is found to be restored at this time, the third component 11c is the originally affected component 11.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
