Conventionally, when connecting the input and output ends of the transmission line of an integrated circuit element (hereinafter referred to as MIC) of a high frequency band circuit, the first
As shown in the figure, a structure is used in which transmission lines (striplines) 11 and 12 of MICs 1 and 2 that are arranged opposite each other are connected with a gold ribbon wire 3, but the equivalent circuit of this connection is L and C as shown in the figure
It will be configured and connected. However, with this kind of connection structure, in recent years, as so-called millimeter wave MICs of 30 GHz and above have been developed and put into practical use, rapid mismatching (mismatching) occurs due to the susceptance of the connection. )
occurs. Therefore, the length of the ribbon wire for connection is made as short as possible by connecting the opposing MICs close together, but if these opposing gaps are eliminated, there is a risk of cracks occurring on the board due to thermal expansion, so it takes a considerable amount of time. Gaps are necessary.

Therefore, when multiple MICs are connected in series, the mounting case becomes large, and the inside of the sealed case becomes a kind of cavity resonator, and the resulting resonant frequency is included in the signal band, resulting in changes in characteristics. May cause deterioration. Therefore, shielding plates are installed at key points or radio wave absorbers are pasted on the case lid. Alternatively, it is possible to connect the opposite sides using a coaxial connector 4 as shown in Fig. 3 in an appropriate unit, but this connection method is not recommended because transmission loss increases and impedance matching is difficult to adjust in the millimeter wave band. is not desirable.

On the other hand, in the connection method using the gold ribbon wire, the thickness of the MIC board for millimeter waves in the ultra-high frequency band must be sufficiently small compared to the wavelength to avoid the effects of higher-order modes (for example, in the case of 50 GHz with an alumina board, The thickness is about 0.2~0.3mm). As a result, the width of the transmission line on the board becomes narrower, so the connection state of the ribbon wire becomes delicate, and changes in the connection state greatly affect the connection characteristics.

In a connection structure in which two channels are connected at high frequency at their opposing ends, a through hole is provided in the main part of the carrier in which each MIC is mounted, and the through hole is used as a waveguide, and both sides of the waveguide are connected at a predetermined wavelength. The present invention is characterized in that a waveguide short circuiter is configured to short-circuit the MIC, and the transmission line to which the MIC is to be connected is connected via the waveguide.

FIG. 4 is a perspective view of a main part of an embodiment of the MIC connection structure according to the present invention.
1' are arranged to protrude above the through hole 61 of the carrier 6 and face each other. The protruding ends 51, 51' have circuit patterns 5 as strip lines to which the MICs 5, 5' are connected, respectively.
2 and 52' are formed and function as an antenna section for transmitting data through the through hole 61. Further, the through hole 61 has a well-known size and shape of a waveguide determined for the frequency used in the MIC, and is rectangular in the figure, but may be other circular or elliptical shapes. A pair of waveguide shunts 7 have a recess 71 having a waveguide size and shape corresponding to the through hole 61 of the carrier 6, and cover both sides of the carrier 6. The depth of the recess 71 is then substantially the same as that of the protruding end 5 of the MIC.
The dimensions are such that the 1,51' portion is short-circuited to the operating frequency. The cutout 72 is the protruding end 51, 5 of the MIC.

With the above configuration in which a pair of waveguide short circuits 7, 7 are attached and fixed on both sides of the carrier 6, when a predetermined high frequency signal from one MIC 5 is transmitted to the protruding end portion 51, for example, The high frequency signal is converted from the strip line transmission mode to the waveguide mode in this part and is radiated to the short circuit 7 and the through hole 61 of the carrier 6. This conversion is performed extremely efficiently, and since the terminals are matched by the short circuit 7, the high frequency signal becomes a waveguide mode and is transmitted through the through hole 6 of the carrier 6.
propagates inside toward the other surface. The high frequency signal that has reached the protruding end 51' of the opposing MIC 5' is directed to the strip line of the MIC 5' in a completely opposite relationship to the radiation caused by the MIC 5 and the short circuit 7. The waveguide mode is converted to the strip line transmission mode and transmitted to the MIC 5. In this case as well, the conversion is efficiently performed by the other terminal 7 which short-circuits the protruding end 51'.

If the depth of the recess 71 of the short circuit 7 is not a fixed type but a well-known short plunger type in which the position of the bottom surface can be varied, it is possible to measure the optimum end-circuit matching in detail and change the frequency. can also be easily dealt with.

FIG. 5 is a side sectional view of another embodiment of the present invention, showing only the main parts. The difference between this embodiment and FIG. 4 is that in FIG. 4, one MIC 5' is disposed opposite to the other surface of the carrier 6 in the extending direction of the MIC 5.
In FIG. 5, one MIC 5' is disposed opposite to the MIC 5 with a carrier 6 interposed therebetween.

As explained above, in the present invention, since the high frequency signal of the MIC is connected via the waveguide, the conversion connection at the connection part is performed efficiently, so there is no problem with the conventional problems caused by gaps, thermal expansion, etc. It is a connection structure. In addition, finely optimized connections can be easily achieved, and by placing a radio wave absorber on the carrier surface where the MIC is not mounted, resonance phenomena can be prevented when the device is sealed in a case. Of course, it is possible to cascade a large number of connection structures as in the embodiment and configure connection portions in each direction.
