[0009] [1] Overview of the embodiment (1) An electronic component according to one aspect of the present disclosure comprises an element body formed by stacking a plurality of insulating layers and a plurality of conductor layers, and a plurality of terminals arranged on the element body, the electronic component comprising: a first filter circuit configured by at least one or more conductor layers of the plurality of conductor layers and processing signals of a first frequency band; a second filter circuit configured by at least one or more conductor layers of the plurality of conductor layers and processing signals of a second frequency band that is a frequency band lower than the first frequency band; and a third filter circuit configured by at least one or more conductor layers of the plurality of conductor layers and processing signals of a third frequency band that is a frequency band higher than the second frequency band, the plurality of terminals including a first terminal, one end of the first filter circuit electrically connected to the first terminal, one end of the second filter circuit and one end of the third filter circuit electrically connected to the other end of the first filter circuit, and the first filter circuit is arranged between the second filter circuit and the third filter circuit in a plan view in the stacking direction of the element body.

[0010] In an electronic component according to one aspect of the present invention, one end of the first filter circuit is electrically connected to a first terminal, and one end of the second filter circuit and one end of the third filter circuit are electrically connected to the other end of the first filter circuit. With this configuration, a first frequency band that is to be commonly processed by the two filter circuits, the second filter circuit and the third filter circuit, can be processed by the first filter circuit. In this manner, the electronic component shares the first filter circuit that processes signals in the first frequency band between the two filter circuits, the second filter circuit and the third filter circuit. This allows the electronic component to reduce the number of elements (components) to be mounted. This allows for a relatively small electronic component. Furthermore, by sharing the first filter circuit between the second filter circuit and the third filter circuit, the electronic component achieves high attenuation characteristics. Therefore, the electronic component achieves excellent characteristics.

[0011] In the electronic component, the first filter circuit is disposed between the second filter circuit and the third filter circuit in a plan view in the stacking direction of the multiple insulating layers. In this way, in the electronic component, the first filter circuit is disposed between the second filter circuit and the third filter circuit, ensuring a sufficient distance between the second filter circuit, which processes signals in the second frequency band, and the third filter circuit, which processes signals in the third frequency band. This improves the isolation between the second filter circuit and the third filter circuit in the electronic component. Therefore, the electronic component achieves excellent characteristics.

[0012] (2) In the electronic component of (1) above, when the upper limit frequency of the first frequency band is F1, the upper limit frequency of the second frequency band is F2, and the lower limit frequency of the third frequency band is F3, the relationship F1 > F3 > F2 may be satisfied.

[0013] (3) In the electronic component of (1) or (2), the second filter circuit may be arranged at one end of the element body in one direction in a plan view in the stacking direction, the third filter circuit may be arranged at the other end of the element body in the one direction in a plan view in the stacking direction, and the first filter circuit, the second filter circuit, and the third filter circuit may be arranged side by side in one direction. This configuration allows a sufficient distance to be secured between the second filter circuit and the third filter circuit.

[0014] (4) In the electronic component of (3), the plurality of terminals may include a second terminal and a third terminal, the other end of the second filter circuit electrically connected to the second terminal, the other end of the third filter circuit electrically connected to the third terminal, the second terminal being disposed at one end of the element body in one direction, and the third terminal being disposed at the other end of the element body in the one direction. If the second terminal and the third terminal were disposed adjacent to each other, signal propagation (leakage) may occur between the second terminal and the third terminal. In the electronic component, the second terminal is disposed at one end of the element body in the one direction, and the third terminal is disposed at the other end of the element body in the one direction, thereby preventing signal propagation between the second terminal and the third terminal. Therefore, the electronic component further improves isolation between the second filter circuit and the third filter circuit.

[0015] (5) In the electronic component of (4), the plurality of terminals may include a fourth terminal connected to ground, and the fourth terminal may be disposed on the element body between the second terminal and the third terminal in one direction. In this configuration, the third terminal connected to ground is disposed between the second terminal and the third terminal, thereby reducing signal propagation between the second terminal and the third terminal. Therefore, in the electronic component, isolation between the second filter circuit and the third filter circuit is further improved.

[0016] (6) In the electronic component of (4) or (5) above, the first terminal may be arranged at one end of the element body in another direction perpendicular to the one direction, and the second terminal and the third terminal may be arranged at the other end of the element body in the other direction. The first terminal is a terminal (common port) common to the first filter circuit, the second filter circuit, and the third filter circuit. In the electronic component, the first terminal is arranged apart from the second terminal and the third terminal, thereby reducing signal propagation between the second terminal and the third terminal. Therefore, in the electronic component, isolation between the second filter circuit and the third filter circuit is further improved.

[0017] (7) In the electronic component of (6), the first filter circuit may have a first inductor including a first winding portion formed using a conductor pattern arranged on one or more of the plurality of conductor layers, and the first winding portion may be arranged between an area in which the second filter circuit is arranged and an area in which the third filter circuit is arranged in a plan view in the stacking direction. In this configuration, the first winding portion of the first filter circuit is arranged between the second filter circuit and the third filter circuit, thereby ensuring a distance between the second filter circuit and the third filter circuit. This further improves isolation between the second filter circuit and the third filter circuit in the electronic component.

[0018] (8) In any one of the electronic components described in (1) to (7), in a plan view in the stacking direction, the area of ​​the first region in which the first filter circuit is disposed may be smaller than the area of ​​the second region in which the second filter circuit is disposed and the area of ​​the third region in which the third filter circuit is disposed. The upper limit value of the first frequency band processed by the first filter circuit shared by the second filter circuit and the third filter circuit may be higher than the frequencies of the second frequency band processed by the second filter circuit and the third frequency band processed by the third filter circuit. In this case, the length of the conductors constituting the first filter circuit in the electronic component can be short, and the number of elements can be reduced. As a result, in the electronic component, the area of ​​the first region in which the first filter circuit is disposed can be smaller than the area of ​​the second region in which the second filter circuit is disposed and the area of ​​the third region in which the third filter circuit is disposed. This makes it possible to realize a relatively small electronic component.

[0019] (9) In the electronic component of (8) above, the area of ​​the second region may be equal to or greater than the area of ​​the third region.

[0020] (10) In the electronic component of (5), the plurality of terminals may include a fifth terminal and a sixth terminal, each connected to ground, the first filter circuit being connected to the fourth terminal, the second filter circuit being connected to the fifth terminal, and the third filter circuit being connected to the sixth terminal, and the fourth terminal, the fifth terminal, and the sixth terminal may not be electrically connected to each other within the element body. In this configuration, the fourth terminal, the fifth terminal, and the sixth terminal are each electrically independently connected to ground. This improves isolation between the first filter circuit, the second filter circuit, and the third filter circuit in the electronic component.

[0021] (11) In the electronic component of (7), the second filter circuit may include a second inductor including a second winding portion formed using a conductor pattern arranged on one or more of the plurality of conductor layers, and the third filter circuit may include a third inductor including a third winding portion formed using a conductor pattern arranged on one or more of the plurality of conductor layers, wherein the second inductor is arranged adjacent to the first inductor in one direction, the third inductor is arranged adjacent to the first inductor in the other direction, and the central axes of the first inductor, the second inductor, and the third inductor may be offset from each other in another direction orthogonal to the one direction in a plan view in the stacking direction. With this configuration, it is possible to adjust the degree of coupling between the first inductor, the second inductor, and the third inductor.

[0022] (12) In the electronic component of (11) above, the area of ​​the first winding portion of the first inductor may be smaller than the area of ​​the second winding portion of the second inductor and the area of ​​the third winding portion of the third inductor.

[0023] (13) In the electronic component of (11) or (12) above, one end of the first inductor may be electrically connected to the first terminal, and the first winding portion of the first inductor may have a first connection portion electrically connected to the second inductor and a second connection portion electrically connected to the third inductor, and in the first winding portion, the first connection portion may be disposed between the one end of the first inductor and the second connection portion.

The substrate 2 has, as its outer surfaces, a pair of opposing end faces 2 a, 2 b, a pair of opposing main faces 2 c, 2 d, and a pair of opposing side faces 2 e, 2 f.

[0027] The opposing direction in which the pair of end faces 2a, 2b face each other is the first direction (one direction) D1. The opposing direction in which the pair of main faces 2c, 2d face each other is the second direction D2. The opposing direction in which the pair of side faces 2e, 2f face each other is the third direction (other direction) D3. In this embodiment, the first direction D1 is the longitudinal direction of the substrate 2. The second direction D2 is the height direction of the substrate 2 and is perpendicular to the first direction D1. The third direction D3 is the width direction of the substrate 2 and is perpendicular to the first direction D1 and the second direction D2.

[0028] The pair of end faces 2a, 2b extend in the second direction D2 to connect the pair of main faces 2c, 2d. The pair of end faces 2a, 2b also extend in the third direction D3. The pair of side faces 2e, 2f extend in the second direction D2 to connect the pair of main faces 2c, 2d. The pair of side faces 2e, 2f also extend in the first direction D1.

Examples of such materials include, but are not limited to, silicon single crystal, alumina, sapphire, aluminum nitride, MgO single crystal, and SrTiO ３ Single crystal, surface-oxidized silicon, glass, quartz, ferrite, etc. can be used.

[0030] The insulator 3 has a rectangular parallelepiped shape. The insulator 3 has, as its outer surfaces, a pair of end faces 3a, 3b facing each other, a pair of main faces 3c, 3d facing each other, and a pair of side faces 3e, 3f facing each other. The pair of end faces 3a, 3b face each other in a first direction D1. The pair of main faces 3c, 3d face each other in a second direction D2.

The dimension of the insulator 3 in the first direction D1 is equal to the dimension of the substrate 2 in the first direction D1. The dimension of the insulator 3 in the third direction D3 is equal to the dimension of the substrate 2 in the third direction D3.

[0032] In this embodiment, "equivalent" does not only mean equal, but also may mean values ​​that include slight differences or manufacturing errors within a preset range. For example, if multiple values ​​are within a range of ±5% of the average value of the multiple values, the multiple values ​​are defined as equivalent.

[0033] The insulator 3 is configured by stacking multiple insulator layers (not shown). The insulator layers are made of an organic insulating material such as polyimide. The insulator layers are stacked in the second direction D2. That is, the second direction D2 is the stacking direction. In an actual insulator 3, the multiple insulator layers are integrated to the extent that the boundaries between the layers are not visible.

[0034] The substrate 2 and the insulator 3 are integrally formed. The substrate 2 and the insulator 3 are disposed such that the main surface 2c and the main surface 3d face each other.

When the fifth terminal electrode 8 functions as an input terminal, the third terminal electrode 6 may function as an output terminal that outputs a signal of a specific frequency band among signals input from the fifth terminal electrode 8. In this case, the frequency band of the signal output from the first terminal electrode 4 may be a higher frequency band than the frequency band of the signal output from the third terminal electrode 6.

In this embodiment, the area of ​​the second region A2 of the second filter circuit FC2 is equal to or larger than the area of ​​the third region A3 of the third filter circuit FC3. That is, in this embodiment, the electronic component 1 satisfies the relationship: area of ​​the first region A1 < area of ​​the third region A3 ≦ area of ​​the second region A2.

[0088] The area of ​​the first region A1 in which the first filter circuit FC1 is disposed is the area of ​​the region in which the physical conductor patterns that realize the first filter circuit FC1 are disposed. Specifically, the area of ​​the first region A1 is the total area of ​​the conductor patterns that make up the inductor L1, capacitor C1, capacitor C2, and capacitor C3. The area of ​​the second region A2 in which the second filter circuit FC2 is disposed is the area of ​​the region in which the physical conductor patterns that realize the second filter circuit FC2 are disposed.

The area of ​​the third region A3 in which the third filter circuit FC3 is disposed is the area of ​​the region in which the physical conductor patterns that realize the third filter circuit FC3 are disposed. Specifically, the area of ​​the third region A3 is the total area of ​​the conductor patterns that make up the inductor L4, inductor L5, capacitor C8, capacitor C9, capacitor C10, capacitor C11, capacitor C12, and capacitor C13.

[0089] In the electronic component 1, the area of ​​the winding portion W1 of the inductor L1 is smaller than the areas of the winding portions W2 and W3 of the inductors L2 and L3 and the areas of the winding portions W4 and W5 of the inductors L4 and L5 (W1 < W2, W3, W4, W5). The area of ​​the winding portion W1 is the area of ​​a region where a physical conductor pattern that realizes the winding portion W1 is arranged. Specifically, the area of ​​the winding portion W1 may be, for example, the total area of ​​the conductor patterns that make up the inductor L1 when viewed from the second direction D2. The area of ​​the winding portion W2 is the area of ​​a region where a physical conductor pattern that realizes the winding portion W2 is arranged. Specifically, the area of ​​the winding portion W2 may be, for example, the total area of ​​the conductor patterns that make up the inductor L2 when viewed from the second direction D2. The area of ​​the winding portion W3 is the area of ​​a region where a physical conductor pattern that realizes the winding portion W3 is arranged. Specifically, the area of ​​the winding portion W3 may be, for example, the total area of ​​the conductor patterns that make up the inductor L3 when viewed from the second direction D2.

[0090] The area of ​​the winding portion W4 is the area of ​​a region where the physical conductor patterns that realize the winding portion W4 are arranged. Specifically, the area of ​​the winding portion W4 may be, for example, the total area of ​​the conductor patterns that make up the inductor L4 when viewed from the second direction D2. The area of ​​the winding portion W5 is the area of ​​a region where the physical conductor patterns that realize the winding portion W5 are arranged. Specifically, for example, the area of ​​the winding portion W5 may be, for example, the total area of ​​the conductor patterns that make up the inductor L5 when viewed from the second direction D2.

[0091] In the electronic component 1, the central axis (coil axis) AX1 of the inductor L1, the central axis AX2 of the inductor L2, the central axis AX3 of the inductor L3, the central axis AX4 of the inductor L4, and the central axis AX5 of the inductor L5 are aligned along the second direction D2. In the electronic component 1, in a plan view in the second direction D2, the central axis AX1 of the inductor L1, the central axis AX2 of the inductor L2, the central axis AX3 of the inductor L3, the central axis AX4 of the inductor L4, and the central axis AX5 of the inductor L5 are offset from one another in the third direction D3. In this embodiment, the central axis AX2 of the inductor L2, the central axis AX3 of the inductor L3, the central axis AX4 of the inductor L4, and the central axis AX5 of the inductor L5 are offset toward the side surface 3 f of the insulator 3 with respect to the central axis AX1 of the inductor L1.

[0092] As described above, in the electronic component 1 according to this embodiment, one end of the first filter circuit FC1 is electrically connected to the fifth terminal electrode 8, and one end of the second filter circuit FC2 and one end of the third filter circuit FC3 are electrically connected to the other end of the first filter circuit FC1. With this configuration, a first frequency band that is to be commonly processed by the two filter circuits, the second filter circuit FC2 and the third filter circuit FC3, can be processed by the first filter circuit FC1. In this manner, in the electronic component 1, the first filter circuit FC1 that processes signals in the first frequency band is shared by the two filter circuits, the second filter circuit FC2 and the third filter circuit FC3. This allows the electronic component 1 to reduce the number of elements (components) to be mounted. This allows for a relatively small electronic component 1 to be realized. Furthermore, by sharing the first filter circuit FC1 between the second filter circuit FC2 and the third filter circuit FC3, the electronic component 1 achieves high attenuation characteristics. Therefore, the electronic component 1 achieves excellent characteristics.

[0093] In the electronic component 1, the first filter circuit FC1 is disposed between the second filter circuit FC2 and the third filter circuit FC3 in a plan view in the second direction D2. In this way, in the electronic component 1, the first filter circuit FC1 is disposed between the second filter circuit FC2 and the third filter circuit FC3, ensuring a sufficient distance between the second filter circuit FC2, which processes signals in the second frequency band, and the third filter circuit FC3, which processes signals in the third frequency band. This improves the isolation between the second filter circuit FC2 and the third filter circuit FC3 in the electronic component 1. Therefore, the electronic component 1 exhibits favorable characteristics.

[0094] In the electronic component 1 according to this embodiment, the second filter circuit FC2 is disposed on the end face 3b side of the insulator 3 in plan view in the second direction D2, and the third filter circuit FC3 is disposed on the end face 3a side of the insulator 3 in plan view in the second direction D2. The first filter circuit FC1, the second filter circuit FC2, and the third filter circuit FC3 are disposed side by side in the first direction D1. This configuration ensures a sufficient distance between the second filter circuit FC2 and the third filter circuit FC3.

[0095] In the electronic component 1 according to this embodiment, the second filter circuit FC2 is electrically connected to the third terminal electrode 6, and the third filter circuit FC3 is electrically connected to the first terminal electrode 4. The third terminal electrode 6 is disposed on the end face 3b side of the insulator 3, and the first terminal electrode 4 is disposed on the end face 3a side of the insulator 3. If the first terminal electrode 4 and the third terminal electrode 6 were disposed adjacent to each other, signal propagation (leakage) might occur between the first terminal electrode 4 and the third terminal electrode 6. In the electronic component 1, the first terminal electrode 4 is disposed on the end face 3a side of the insulator 3, and the third terminal electrode 6 is disposed on the end face 3b side of the insulator 3, so signal propagation between the first terminal electrode 4 and the third terminal electrode 6 can be prevented. Therefore, in the electronic component 1, isolation between the second filter circuit FC2 and the third filter circuit FC3 is further improved.

[0096] In the electronic component 1 according to this embodiment, the second terminal electrode 5 connected to ground is disposed in the insulator 3 between the first terminal electrode 4 and the third terminal electrode 6 in the first direction D1. In this configuration, the second terminal electrode 5 connected to ground is disposed between the first terminal electrode 4 and the third terminal electrode 6, which further reduces signal propagation between the first terminal electrode 4 and the third terminal electrode 6. Therefore, in the electronic component 1, the isolation between the second filter circuit FC2 and the third filter circuit FC3 is further improved.

[0097] In the electronic component 1 according to this embodiment, the fifth terminal electrode 8 is disposed on the side surface 3 f of the insulator 3, and the first terminal electrode 4 and the third terminal electrode 6 are disposed on the side surface 3 e of the insulator 3. The fifth terminal electrode 8 is a terminal electrode (common port P1) shared by the first filter circuit FC1, the second filter circuit FC2, and the third filter circuit FC3. In the electronic component 1, the fifth terminal electrode 8 is disposed at a distance from the first terminal electrode 4 and the third terminal electrode 6, which further reduces signal propagation between the first terminal electrode 4 and the third terminal electrode 6. Therefore, in the electronic component 1, the isolation between the second filter circuit FC2 and the third filter circuit FC3 is further improved.

[0098] In the electronic component 1 according to this embodiment, the first filter circuit FC1 includes an inductor L1 formed by a winding portion W1. The winding portion W1 is disposed between the second region A2, in which the second filter circuit FC2 is disposed, and the third region A3, in which the third filter circuit FC3 is disposed, in a plan view in the second direction D2. In this configuration, the winding portion W1 of the first filter circuit FC1 is disposed between the second filter circuit FC2 and the third filter circuit FC3, ensuring a sufficient distance between the second filter circuit FC2 and the third filter circuit FC3. This improves isolation between the second filter circuit FC2 and the third filter circuit FC3 in the electronic component 1.

[0099] In the electronic component 1 according to this embodiment, in a plan view in the second direction D2, the area of ​​the first region A1 in which the first filter circuit FC1 is disposed is smaller than the area of ​​the second region A2 in which the second filter circuit FC2 is disposed and the area of ​​the third region A3 in which the third filter circuit FC3 is disposed. The upper limit value of the first frequency band processed by the first filter circuit FC1, which is shared by the second filter circuit FC2 and the third filter circuit FC3, is higher than the frequencies of the second frequency band processed by the second filter circuit FC2 and the third frequency band processed by the third filter circuit FC3. In this case, the length of the conductors constituting the first filter circuit FC1 can be shortened, and the number of elements can be reduced. As a result, the area of ​​the first region A1 in which the first filter circuit FC1 is disposed can be smaller than the area of ​​the second region A2 in which the second filter circuit FC2 is disposed and the area of ​​the third region A3 in which the third filter circuit FC3 is disposed. This allows the electronic component 1 to be relatively small.

[0100] In the electronic component 1 according to this embodiment, the first filter circuit FC1 is connected to the second terminal electrode 5, the second filter circuit FC2 is connected to the sixth terminal electrode 9, and the third filter circuit FC3 is connected to the fourth terminal electrode 7. The second terminal electrode 5, the fourth terminal electrode 7, and the sixth terminal electrode 9 are not electrically connected to one another within the insulator 3.
