[First Embodiment]
The filter according to the first embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing a filter according to the present embodiment. FIG. 2A is a plan view showing a filter according to the present embodiment. FIG. 2B is a cross-sectional view showing a filter according to the present embodiment. 1 to 2B show an example in which three resonators 11A to 11C are provided.

As shown in FIGS. 1 to 2B, the filter 10 according to the present embodiment is provided with the dielectric substrate 14. The dielectric substrate 14 is formed in a rectangular parallelepiped shape, for example, but is not limited thereto. The dielectric substrate 14 is formed by laminating a plurality of ceramic sheets (dielectric ceramic sheets).

The dielectric substrate 14 has two main surfaces 14a and 14b and four side surfaces 14c to 14f. The direction along the normal direction of the side surfaces 14c and 14d, more specifically, the normal direction of the side surfaces 14c and 14d is defined as the X direction. The direction along the normal direction of the side surface 14e and the side surface 14f, more specifically, the normal direction of the side surface 14e and 14f is defined as the Y direction. The direction along the normal direction of one main surface (first main surface) 14a and the other main surface (second main surface) 14b of the dielectric substrate 14, more specifically, the normals of the main surfaces 14a and 14b. The direction is the Z direction.

A first main surface side shielding conductor (lower shielding conductor, shielding conductor) 12A is formed on the main surface 14a side of the dielectric substrate 14, that is, on the lower side of the dielectric substrate 14 in FIG. A second main surface side shielding conductor (upper shielding conductor, shielding conductor) 12B is formed on the main surface 14b side of the dielectric substrate 14, that is, on the upper side of the dielectric substrate 14 in FIG.

Input / output terminals 22A are formed on the side surface 14c of the dielectric substrate 14. Input / output terminals 22B are formed on the side surface 14d of the dielectric substrate 14. The input / output terminal 22A is coupled to the second main surface side shielding conductor 12B via the connection line 32a. Further, the input / output terminal 22B is coupled to the second main surface side shielding conductor 12B via the connection line 32b.

A shielding conductor 12Ca is formed on the side surface 14e of the dielectric substrate 14. A shielding conductor 12Cb is formed on the side surface 14f of the dielectric substrate 14. The shielding conductors 12Ca and 12Cb are formed in a plate shape.

Capacitor electrodes (first capacitor electrodes, first strip lines) 18A to 18C facing the first main surface side shielding conductor 12A are formed in the dielectric substrate 14. In FIG. 1, the capacitor electrodes 18A to 18C are shown as squares, but the shape of the capacitor electrodes 18A to 18C is not limited to a square. For example, the shape of the capacitor electrodes 18A to 18C may be rectangular. Reference numeral 18 is used when describing the capacitor electrodes in general, and reference numerals 18A to 18C are used when describing the individual capacitor electrodes.

A via electrode portion 20A, a via electrode portion 20B, and a via electrode portion 20C are further formed in the dielectric substrate 14. Reference numeral 20 is used when describing the via electrode portion in general, and reference numerals 20A to 20C are used when describing the individual via electrode portions.

The via electrode portion 20 is composed of a plurality of via electrodes 24. The via electrode 24 is embedded in each via hole formed in the dielectric substrate 14. When viewed from above, the plurality of via electrodes 24 constituting the via electrode portion 20 are arranged along a virtual ring 26, more specifically, a virtual circle. Since the via electrode portion 20 is configured by arranging the plurality of via electrodes 24 along the virtual ring 26, the via electrode portion 20 is a large-diameter via electrode corresponding to the virtual ring 26. Can behave like this. Since the via electrode portion 20 is composed of a plurality of via electrodes 24 having a relatively small diameter, the manufacturing process can be simplified. Further, since the via electrode portion 20 is composed of a plurality of via electrodes 24 having a relatively small diameter, the variation in the diameter of the via electrode portion 20 can be reduced. Further, since the via electrode portion 20 is formed by a plurality of via electrodes 24 having a relatively small diameter, less material such as silver to be embedded in the via can be used, and cost reduction can be realized.

One end, that is, the lower end of the via electrode portion 20, is connected to the capacitor electrode 18. The other end, that is, the upper end of the via electrode portion 20, is connected to the second main surface side shielding conductor 12B. As described above, the via electrode portion 20 is formed from the capacitor electrode 18 to the second main surface side shielding conductor 12B.

The structure 16A is composed of the capacitor electrode 18A and the via electrode portion 20A. The structure 16B is composed of the capacitor electrode 18B and the via electrode portion 20B. The structure 16C is composed of the capacitor electrode 18C and the via electrode portion 20C. Reference numerals 16 are used when describing the structures in general, and reference numerals 16A to 16C are used when describing the individual structures. A pattern (not shown) may be appropriately provided between the respective structures 16.

The filter 10 is provided with a plurality of resonators including the structures 16A to 16C, that is, a resonator 11A, a resonator 11B, and a resonator 11C. Reference numerals 11 will be used when the resonators in general will be described, and reference numerals 11A to 11C will be used when the individual resonators will be described.

The resonator 11A and the resonator 11C are arranged so as to be adjacent to each other. The resonator 11C and the resonator 11B are arranged so as to be adjacent to each other. Each of the plurality of resonators 11 is provided with one via electrode portion 20.

As shown in FIG. 2A, the via electrode portion 20A, the via electrode portion 20B, and the via electrode portion 20C are displaced from each other in the X direction. The position of the center P3 of the via electrode portion 20C in the X direction is between the position of the center P1 of the via electrode portion 20A in the X direction and the position of the center P2 of the via electrode portion 20B in the X direction. The position of the center P1 of the via electrode portion 20A in the Y direction is equivalent to the position of the center P2 of the via electrode portion 20B in the Y direction. The via electrode portion 20C is displaced in the Y direction with respect to the via electrode portion 20A and the via electrode portion 20B. The via electrode portion 20A and the via electrode portion 20B are located on the side surface 14e side. The via electrode portion 20C is located on the side surface 14f side.

As described above, in the present embodiment, the position of the center P1 of the via electrode portion 20A and the position of the center P3 of the via electrode portion 20C are not only shifted from each other in the X direction but also shifted from each other in the Y direction. ing. Therefore, according to the present embodiment, the distance between the via electrode portions 20A and 20C can be increased without increasing the distance between the via electrode portions 20A and 20C in the X direction. Further, according to the present embodiment, the position of the center P2 of the via electrode portion 20B and the position of the center P3 of the via electrode portion 20C are not only shifted from each other in the X direction but also shifted from each other in the Y direction. ing. Therefore, according to the present embodiment, the distance between the via electrode portions 20B and 20C can be increased without increasing the distance between the via electrode portions 20B and 20C in the X direction. Therefore, according to the present embodiment, the degree of coupling between the adjacent resonators 11A to 11C can be reduced without increasing the distance between the adjacent resonators 11A to 11C in the X direction. Therefore, according to the present embodiment, it is possible to obtain a filter 10 having good characteristics while keeping the size of the filter 10 small.

FIG. 3 is a perspective view showing a filter according to the present embodiment. FIG. 4 is a plan view showing a filter according to the present embodiment. 3 and 4 show an example in which four resonators 11A to 11D are provided.

A capacitor electrode 18D facing the first main surface side shielding conductor 12A is further formed in the dielectric substrate 14. A via electrode portion 20D is further formed in the dielectric substrate 14. The structure 16D is composed of the capacitor electrode 18D and the via electrode portion 20D. The filter 10 is further provided with a resonator 11D including a structure 16D.

The resonator 11A and the resonator 11C are arranged so as to be adjacent to each other. The resonator 11C and the resonator 11D are arranged so as to be adjacent to each other. The resonator 11D and the resonator 11B are arranged so as to be adjacent to each other.

As shown in FIG. 4, the via electrode portion 20A, the via electrode portion 20B, the via electrode portion 20C, and the via electrode portion 20D are displaced from each other in the X direction. The position of the center P3 of the via electrode portion 20C in the X direction is between the position of the center P1 of the via electrode portion 20A in the X direction and the position of the center P4 of the via electrode portion 20D in the X direction. The position of the center P4 of the via electrode portion 20D in the X direction is between the position of the center P3 of the via electrode portion 20C in the X direction and the position of the center P2 of the via electrode portion 20B in the X direction. The position of the center P1 of the via electrode portion 20A in the Y direction is equivalent to the position of the center P2 of the via electrode portion 20B in the Y direction. The position of the center P3 of the via electrode portion 20C in the Y direction is equivalent to the position of the center P4 of the via electrode portion 20D in the Y direction. The via electrode portion 20C and the via electrode portion 20D are displaced in the Y direction with respect to the via electrode portion 20A and the via electrode portion 20B. The via electrode portion 20A and the via electrode portion 20B are located on the side surface 14e side. The via electrode portion 20C and the via electrode portion 20D are located on the side surface 14f side.

As described above, according to the present embodiment, the position of the center P1 of the via electrode portion 20A and the position of the center P3 of the via electrode portion 20C are not only shifted from each other in the X direction but also from each other in the Y direction. It is staggered. Therefore, according to the present embodiment, the distance between the via electrode portions 20A and 20C can be increased without increasing the distance between the via electrode portions 20A and 20C in the X direction. Further, according to the present embodiment, the position of the center P2 of the via electrode portion 20B and the position of the center P4 of the via electrode portion 20D are not only shifted from each other in the X direction but also shifted from each other in the Y direction. ing. Therefore, according to the present embodiment, the distance between the via electrode portions 20B and 20D can be increased without increasing the distance between the via electrode portions 20B and 20D in the X direction. Therefore, according to the present embodiment, the degree of coupling between the resonators 11A to 11D adjacent to each other can be reduced without increasing the distance between the resonators 11A to 11D adjacent to each other in the X direction. Therefore, according to the present embodiment, it is possible to reduce the degree of coupling between the resonators 11A to 11D adjacent to each other while keeping the size of the filter 10 small, and it is possible to obtain the filter 10 having good characteristics.

Each resonator 11 provided in the filter 10 is considered to behave like a coaxial resonator. 5A and 5B are diagrams showing an example of a model of a coaxial resonator. FIG. 5A is a perspective view, and FIG. 5B is a plan view. In the models shown in FIGS. 5A and 5B, the coaxial resonator 30A is composed of the cylindrical inner conductor 28A and the cylindrical outer conductor 28B. The outer conductor 28B is formed around the inner conductor 28A with the central axis of the inner conductor 28A as the center. The diameter of the inner conductor 28A is DA, and the diameter of the outer conductor 28B is DB.

A general coaxial resonator is a columnar coaxial resonator as shown in FIGS. 5A and 5B. However, it is easier to think of the resonator 11 provided in the filter 10 as a model of a square columnar coaxial resonator than as a model of a columnar coaxial resonator. 5C and 5D are diagrams showing other examples of coaxial resonator models. A model of a square columnar coaxial resonator is shown in FIGS. 5C and 5D. FIG. 5C is a perspective view, and FIG. 5D is a plan view. In the models shown in FIGS. 5C and 5D, the coaxial resonator 30B is composed of the cylindrical inner conductor 28A and the square tubular outer conductor 28C. The outer conductor 28C is formed around the inner conductor 28A with the central axis of the inner conductor 28A as the center. The diameter of the inner conductor 28A is DA, and the diameter of the outer conductor 28C is DB.

FIG. 6 is a graph showing the simulation result of the Q value of the coaxial resonator. FIG. 6 shows the Q value of the cylindrical coaxial resonator 30A and the Q value of the square columnar coaxial resonator 30B. The horizontal axis shows the diameter ratio (DA / DB), and the vertical axis shows the Q value. When performing the simulation, the outer diameter DB was set to 2 mm. As can be seen from FIG. 6, the Q value peaks when the diameter ratio is about 0.3. The Q value of the square columnar coaxial resonator 30B is higher than the Q value of the columnar coaxial resonator 30A because the outer conductor 28C of the square columnar coaxial resonator 30B is outside the columnar coaxial resonator 30A. It is considered that the loss is small because the cross-sectional area is larger than that of the conductor 28B.

As described above, in the present embodiment, the via electrode portion 20 is composed of a plurality of via electrodes 24 arranged in a ring shape. The via electrode portion 20 corresponds to the internal conductor of the coaxial resonator. 7A and 7B are diagrams showing still another example of the coaxial resonator model. 7A and 7B show a model of a coaxial resonator in which an internal conductor is composed of a plurality of via electrodes arranged in an annular shape. FIG. 7A is a perspective view, and FIG. 7B is a plan view. In the models shown in FIGS. 7A and 7B, the coaxial resonator 30C is composed of the inner conductor 28D and the square tubular outer conductor 28C. The inner conductor 28D is composed of a plurality of via electrodes 24 arranged along a virtual ring 26. The outer conductor 28C is formed around the inner conductor 28D with the central axis of the inner conductor 28D as the center. The diameter of the inner conductor 28D is DA, and the diameter of the outer conductor 28C is DB. The diameter of the virtual ring 26 corresponds to the diameter DA of the inner conductor 28D.

FIG. 8 is a graph showing the simulation result of the Q value of the coaxial resonator. FIG. 8 shows the Q value of the coaxial resonator 30B described above and the Q value of the coaxial resonator 30C described above. The horizontal axis shows the diameter ratio (DA / DB), and the vertical axis shows the Q value. When performing the simulation, the outer diameter DB was set to 2 mm, and the diameter of the via electrode 24 was set to 100 μm. As can be seen from FIG. 8, the Q value becomes sufficiently high in the range of the diameter ratio of 0.2 to 0.4.

FIG. 9 is a graph showing the simulation result of the Q value of the coaxial resonator. FIG. 9 shows the relationship between the diameter of the outer conductor 28C and the Q value. As can be seen from FIG. 9, the Q value increases as the distance between the inner conductor 28D and the outer conductor 28C increases.

FIG. 10 is a plan view showing an example of the layout of the resonator. FIG. 10 shows an example of a layout in which four resonators 11A to 11D are arranged. Although the case where four resonators 11A to 11D are arranged will be described here as an example, the number of resonators 11 is not limited to four. The number of resonators 11 may be three or five or more.

In the layout shown in FIG. 10, the dimension of one square is 640 μm, but the size is not limited to this. In the layout shown in FIG. 10, the dimension of the filter 10 in the X direction is 4.48 mm, and the dimension of the filter 10 in the Y direction is 3.2 mm, but the present invention is not limited to this. In such a layout, the diameter ratio (DA / DB) is 0.33. As described above with reference to FIG. 8, the Q value becomes sufficiently high in the range of the diameter ratio of 0.2 to 0.4. Therefore, if the layout is as shown in FIG. 10, it is possible to obtain a filter 10 having a good Q value.

FIG. 11 is a graph showing the characteristics of the filter according to the present embodiment. The horizontal axis shows the frequency, the left vertical axis shows the attenuation loss or the reflection loss, and the right vertical axis shows the insertion loss. The solid line shows the case of the embodiment, that is, the present embodiment, and the broken line shows the case of the comparative example. In the comparative example, four resonators were arranged along the longitudinal direction of the filter, and two via electrodes were provided for each resonator.

As can be seen from FIG. 11, the amount of attenuation in the attenuation band of the filter according to the embodiment and the amount of attenuation in the attenuation band of the filter according to the comparative example are equivalent. Further, the reflection loss in the pass band of the filter according to the example and the reflection loss in the pass band of the filter according to the comparative example are equivalent. The insertion loss in the pass band of the filter according to the embodiment is 1.5 dB, and the insertion loss in the pass band of the filter according to the comparative example is 1.9 dB. That is, the insertion loss in the pass band of the filter according to the embodiment is smaller than the insertion loss in the pass band of the filter according to the comparative example. The margin from the passband end of the frequency at which the insertion loss is 3 dB was 52 MHz in the comparative example, but 68 MHz in the example. From these facts, it can be seen that in the present embodiment, the insertion loss can be significantly improved as compared with the comparative example. As described above, according to the present embodiment, the filter 10 having good characteristics can be obtained.

FIG. 12 is a diagram showing an example of setting the dimensions. As described above, the Q value becomes sufficiently high in the range of the diameter ratio (DA / DB) of 0.2 to 0.4. When the distance DC1 between the shielding conductors 12Ca and 12Cb and the via electrode portion 20 is 0.75DA to 2DA, the diameter ratio (DA / DB) is 0.2 to 0.4. When the distance DC2 between the via electrode portions 20 adjacent to each other is 0.75DA to 2DA, the diameter ratio (DA / DB) is 0.2 to 0.4. The distance DC1 is not the distance between the shielding conductors 12Ca and 12Cb and the center of the via electrode portion 20, but the distance between the shielding conductors 12Ca and 12Cb and the outer edge of the via electrode portion 20, that is, the virtual ring 26. Is. Further, the distance DC2 is not the distance between the centers of the via electrode portions 20 adjacent to each other, but the distance between the outer edges of the via electrode portions 20 adjacent to each other, that is, the distance between the virtual rings 26. As described above, in the present embodiment, for example, the ratio of the distance DC1 between the shielding conductor 12Ca and the via electrode portion 20 to the diameter DA of the virtual ring 26 is set to 0.75 to 2. Further, in the present embodiment, for example, the ratio of the distance DC2 between the via electrode portions 20 adjacent to each other to the diameter DA of the virtual ring 26 is set to 0.75 to 2.

As described above, in the present embodiment, the via electrode portion 20A provided in the resonator 11A and the via electrode portion 20B provided in the resonator 11B are displaced from each other in the X direction. Further, in the present embodiment, the via electrode portion 20C provided in the resonator 11C is displaced in the Y direction with respect to the via electrode portion 20A and the via electrode portion 20B. Therefore, according to the present embodiment, the distance between the via electrode portions 20A and 20C can be increased without increasing the distance between the via electrode portions 20A and 20C in the X direction. Further, according to the present embodiment, the distance between the via electrode portions 20B and 20C can be increased without increasing the distance between the via electrode portions 20B and 20C in the X direction. Therefore, according to the present embodiment, the degree of coupling between the resonators 11A to 11C adjacent to each other can be reduced without increasing the distance between the resonators 11A to 11C adjacent to each other in the X direction. Therefore, according to the present embodiment, it is possible to obtain a filter 10 having good characteristics while keeping the size of the filter 10 small.
