A SAW filter is a component that converts an electromagnetic wave transmitted at the speed of light into a very slow acoustic wave, and extracts only a wavelength of a desired frequency from the wave. In this case, piezoelectric materials are used to convert electromagnetic waves into sound waves. When these materials are used to convert electromagnetic waves into sound waves, two types of sound waves are generated. One is called Surface Wave, and the other is called Bulk Wave. Theoretically, it doesn't matter which of these two waves you use, but the SAW filter uses surface waves. This is why SAW (Surface Acoustic Wave) is called.

In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to intention or custom of users and operators. Therefore, such a definition should be determined based on the contents described throughout the specification.

<First Embodiment>

1A and 1B correspond to a first embodiment of a reverse filter and miso-prevention saw filter package according to the present invention, and show a configuration of a saw filter package for preventing reverse-insertion and misinterpretation by varying the distance between connecting pins. Drawing.

As shown, the saw filter package according to the present invention, a digital saw filter (10) or analog saw filter (10 ') for generating a surface acoustic wave to filter the signal, the bottom of the saw filters (10, 10') And a first connection pin 11 and 11 'electrically connected to the first input terminal of the saw filter and a lower end of the saw filter 10 and 10' to be adjacent to the first connection pin. And a second connection pin 12 and 12 'electrically connected to the second input terminal of the saw filter, and disposed at a lower end of the saw filter 10 and 10' to be adjacent to the second connection pin. Third connecting pins 13 and 13 'electrically connected to the ground terminal of the filter, and are disposed at the lower ends of the saw filters 10 and 10' so as to be adjacent to the third connecting pins, and the first output of the saw filter. Fourth connecting pins 14 and 14 'electrically connected to the terminals, and adjacent to the fourth connecting pins. The Saw "is provided at the lower end of the fifth connecting pin (15, 15 electrically connected to the second output terminal of the filter Saw filter 10,10 'is configured to include a).

In this case, as shown in the drawing, the distance between the first connecting pins 11 and 11 'and the second connecting pins 12 and 12', the second connecting pins 12 and 12 'and the third connecting pin ( 13, 13 ', the gap between the third connecting pin 13, 13' and the fourth connecting pin (14, 14 '), the fourth connecting pin (14, 14') and the fifth connection The connecting pins are arranged such that any one of the gaps between the pins 15, 15 ′ is different from the remaining gaps.

For example, as shown in FIGS. 1A and 1B, in the case of the digital saw filter package, the distance b between the fourth connection pin 14 and the fifth connection pin 15 is equal to the distance between the other pins a. In the case of the analog saw filter package, the distance b between the first connection pin 11 ′ and the second connection pin 12 ′ may be narrower than the distance a between the other pins.

As a matter of course, the distance between the second connection pins 12 and 12 'and the third connection pins 13 and 13' may be adjusted, and it is obvious that not only the distance may be increased but also the distance may be increased.

In this way, if the Saw filter is inserted backwards by adjusting the spacing between the connecting pins of the Saw filter package, or if the Saw filter is inserted where the analog Saw filter is to be inserted, the spacing between the pins of the Saw filter is different so that it is not inserted. It is possible to prevent misunderstanding at the source.

Second Embodiment

2A and 2B correspond to a second embodiment of the reverse filter and miso-prevention saw filter package according to the present invention, and show a configuration of the saw filter package for preventing reverse insertion and mis-insertion by inserting a dummy pin between the connecting pins. One drawing.

Since the basic configuration of the digital or analog saw filter package shown in the drawing is the same as that described with reference to FIGS. 1A and 1A, a description thereof will be omitted herein.

As shown, the present embodiment is characterized in that the dummy pins 16 and 16 'are formed between the connection pins arranged at regular intervals.

The dummy pins 16 and 16 'are connected between the first connection pins 11 and 11' and the second connection pins 12 and 12 ', and the second connection pins 12 and 12' and the third connection. Between the pins 13 and 13 ', between the third connecting pins 13 and 13' and the fourth connecting pins 14 and 14 ', the fourth connecting pins 14 and 14' and the fifth connecting pin ( 15, 15 ').

For example, as illustrated in FIGS. 2A and 2B, in the case of the digital saw filter package, a dummy pin 16 is formed between the first connecting pin 11 and the second connecting pin 12 and the analog saw. In the case of the filter package, the dummy pin 16 ′ may be formed between the second connection pin 12 ′ and the third connection pin 13 ′.

Thus, when the saw filter is inserted backwards by forming dummy pins between the connection pins of the saw filter package or when the digital saw filter is inserted where the analog saw filter is to be inserted, the gap between the pins of the saw filter is not inserted. Inverse and misleading can be blocked at source.

Third Embodiment

3A and 3B correspond to a third embodiment of the reverse filter and miso-prevention saw filter package according to the present invention, and prevents reverse insertion and misomission by forming the thickness of one connection pin to be different from the thickness of the other connection pin. It is a figure which shows the structure of the saw filter package for doing so.

Since the basic configuration of the digital or analog saw filter package shown in the drawing is the same as that described with reference to FIGS. 1A and 1A, a description thereof will be omitted herein.

As shown, in the present embodiment, the first connecting pins 11 and 11 ', the second connecting pins 12 and 12', the third connecting pins 13 and 13 ', and the fourth connecting pins 14, 14 '), or the thickness of any one of the fifth connecting pins 15 and 15' is configured to be different from the thicknesses of the remaining pins.

For example, as illustrated in FIGS. 3A and 3B, in the case of the digital saw filter package, the thickness d of the first connection pin 10 may be formed to be thicker than the thickness c of the other connection pins. In the case of the analog saw filter package, the thickness d of the fifth connection pin 15 ′ may be formed to be thicker than the thickness c of the other connection pin. Of course, it is obvious that it is also possible to form the thickness of a specific connection pin to be thinner than the thickness of another connection pin.

As such, the thickness of one connection pin of the saw filter package is different from that of the other connection pins so that the saw filter is inserted upside down or the digital saw filter is inserted when the analog saw filter is to be inserted. As a result, inverse and incorrect insertion can be prevented.

Fourth Example

4A and 4B correspond to the fourth embodiment of the reverse filter and the miso-prevention saw filter package according to the present invention, and prevent the reverse insertion and the misunderstanding by forming the length of one connection pin to be different from the length of the other connection pin. It is a figure which shows the structure of the saw filter package for doing so.

Since the basic configuration of the digital or analog saw filter package shown in the drawing is the same as that described with reference to FIGS. 1A and 1A, a description thereof will be omitted herein.

As shown, in the present embodiment, the first connecting pins 11 and 11 ', the second connecting pins 12 and 12', the third connecting pins 13 and 13 ', and the fourth connecting pins 14, 14 '), or the length of any one of the fifth connecting pins 15 and 15' is configured to be different from the lengths of the remaining pins.

For example, as illustrated in FIGS. 4A and 4B, in the case of the digital saw filter package, the length f of the first connection pin 10 may be formed to be longer than the length e of the other connection pins. In the case of the analog saw filter package, the length f of the fifth connection pin 15 ′ may be formed to be longer than the length e of the other connection pin. Of course, it is obvious that it is also possible to form the thickness of a specific connection pin shorter than the thickness of another connection pin.

In this way, the length of one connection pin of the saw filter package is different from the length of the other connection pins so that the saw filter is inserted upside down or the digital saw filter is inserted when the analog saw filter is to be inserted. As a result, inverse and incorrect insertion can be prevented.

The above embodiments are one example for preventing inverse and misinsertion, and of course, various modifications are possible, such that the cross-sectional shape of one connection pin is different from the cross-sectional shape of another connection pin.

Although specific embodiments of the present invention have been described in detail above, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. It should be understood that the embodiments described above are exemplary in all respects and that the present invention is not limited to those described in the detailed description. The scope of the present invention is indicated by the following claims rather than the above description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents are included within the scope of the present invention.
