The first pin can be electrically connected to a power supply pin of the radio frequency chip 102, and the second pin can be grounded. The circuit in which the radio frequency chip 102 is located can be decoupled through the capacitor 103.

[0028] It can be understood that the capacitor 103 can be a multilayer ceramic capacitor (MLCC). The first pin and the second pin of the capacitor 103 can be fixed on the substrate 101 by welding, and the pad connected with the first pin can be electrically connected to the power supply pin of the radio frequency chip 102 by a connecting wire or an engraved circuit, so as to realize the electrical connection between the first pin and the power supply pin of the radio frequency chip 102.

[0029] It can be understood that the electronic device 100 can further include a plurality of signal lines, a plurality of connection terminals and other electronic components, and the embodiments of the present application do not limit the same.

[0030] Please refer to Figure 3 In some embodiments, the substrate 101 can include a base 10, a first connection part 20 and a second connection part 30. The base 10 can be a hard plate made of insulating material. The first connection part 20 and the second connection part 30 are located on the same surface of the base 10. The first connection part 20 and the second connection part 30 can both be made of metal conductive material and are fixedly connected with the substrate 101. The first connection part 20 is arranged apart from the radio frequency chip 102 and is electrically connected with the power supply pin of the radio frequency chip 102. The first pin of the capacitor 103 can be fixedly connected and electrically connected with the first connection part 20.

For example, as shown in the drawing, Figure 3 ​As shown in FIG. 6, when the two sides of the first connecting portion 20 in the first direction are not provided with electronic components and solder pads, the plurality of second connecting portions 30 can be arranged on the two sides of the first connecting portion 20 in the first direction and on the side away from the radio frequency chip 102 in the second direction, and the connecting lines of the plurality of second connecting portions 30 can be semicircular arcs. For example, as shown in FIG. 7, when one side of the first connecting portion 20 in the first direction is not provided with electronic components or solder pads, the plurality of second connecting portions 30 can be arranged on the side of the first connecting portion 20 in the first direction which is not provided with electronic components and solder pads, and on the side away from the radio frequency chip 102 in the second direction, so that the second connecting member 31 can be a quarter of a circular ring, and the first connecting portion 20 is arranged at the center of the circular ring. Figure 4 As shown in FIG. 7, when one side of the first connecting portion 20 in the first direction is not provided with electronic components or solder pads, the plurality of second connecting portions 30 can be arranged on the side of the first connecting portion 20 in the first direction which is not provided with electronic components and solder pads, and on the side away from the radio frequency chip 102 in the second direction, so that the second connecting member 31 can be a quarter of a circular ring, and the first connecting portion 20 is arranged at the center of the circular ring.

[0040] Please refer to FIGS. 6 and 7 Figure 5 and Figure 6 In some embodiments, among the plurality of second connecting portions 30, two adjacent second connecting portions 30 are fixedly connected to each other and cover each other. The plurality of second connecting portions 30 cooperatively form a continuous second connecting member 31.

[0041] In the embodiments of the present application, the shape of the second connecting member 31 formed by the plurality of second connecting portions 30 is not specifically limited. For example, as shown in FIG. 6, when the two sides of the first connecting portion 20 in the first direction are not provided with electronic components and solder pads, the plurality of second connecting portions 30 can be arranged on the two sides of the first connecting portion 20 in the first direction and on the side away from the radio frequency chip 102 in the second direction, so that the second connecting member 31 can be a semicircular ring, and the first connecting portion 20 is arranged at the center of the circular ring. For example, as shown in FIG. 7, when one side of the first connecting portion 20 in the first direction is not provided with electronic components or solder pads, the plurality of second connecting portions 30 can be arranged on the side of the first connecting portion 20 in the first direction which is not provided with electronic components and solder pads, and on the side away from the radio frequency chip 102 in the second direction, so that the second connecting member 31 can be a quarter of a circular ring, and the first connecting portion 20 is arranged at the center of the circular ring. Figure 5 Figure 6 As shown in FIG. 7, when one side of the first connecting portion 20 in the first direction is not provided with electronic components or solder pads, the plurality of second connecting portions 30 can be arranged on the side of the first connecting portion 20 in the first direction which is not provided with electronic components and solder pads, and on the side away from the radio frequency chip 102 in the second direction, so that the second connecting member 31 can be a quarter of a circular ring, and the first connecting portion 20 is arranged at the center of the circular ring.

[0042] In some embodiments, on the side of the substrate 10 provided with the first connecting portion 20 and the second connecting portion 30, the area of the substrate 10 which is not covered by the first connecting portion 20, the second connecting portion 30 and other solder pads and engraved circuits forms an isolation member 40. The isolation member 40 can extend between the first connecting portion 20 and the radio frequency chip 102, between the first connecting portion 20 and each second connecting portion 30, and between the radio frequency chip 102 and each second connecting portion 30, so as to achieve the spaced arrangement of the first connecting portion 20, the second connecting portion 30 and the radio frequency chip 102.

[0043] ​It can be understood that the isolation piece 40 is made of insulating material, and the isolation piece 40 can form a solder mask on the circuit board.

[0044] In the embodiments of the present application, the shape of the first connecting portion 20 is not specifically limited. For example, the first connecting portion 20 can be circular. For another example, the first connecting portion 20 can be rectangular, and the first connecting portion 20 can extend along the first direction or the second direction, or can extend along a direction that forms an acute angle with the first direction and the second direction. In this way, when installing the capacitor 103, the worker can move the capacitor 103 while rotating the capacitor 103, so that the first pin of the capacitor 103 moves on the first connecting portion 20, so as to install the capacitor 103 to a position where the capacitor 103 is less interfered by signals.

[0045] Similarly, in the embodiments of the present application, the shape of the second connecting portion 30 when the plurality of second connecting portions 30 are arranged at intervals is not specifically limited. For example, the second connecting portion 30 can be circular. For another example, the second connecting portion 30 can be rectangular, and the second connecting portion 30 can extend along the first direction or the second direction, or can extend along a direction that forms an acute angle with the first direction and the second direction.

The first connecting portion 20, the second connecting portion 30, the radio frequency chip 102 and the capacitor 103 can be arranged on each substrate 101.

[0047] Through the substrate 101 and the electronic device 100 provided by the embodiments of the present application, when installing the capacitor 103, the worker can adjust the connection position of the second pin of the capacitor 103 without changing the position of the first pin of the capacitor 103, so as to reduce the signal interference received by the capacitor 103, and further reduce the signal interference received by the radio frequency chip 102. The working effect of the radio frequency chip 102 can be improved, and the working effect of the electronic device 100 can be improved.
