般に1/4波長線路で構成されている。 FIG. 2 is a sectional view thereof. As shown in these figures, the input terminal 1 is connected to one end of the strip line via a capacitor 6, and the other end is connected to one end of the coplanar line formed on the bottom surface of the substrate 4 via a through hole 9. It is connected. Also,
The other end of the coplanar line has two diodes 7
and 8 to one end of the slot line 5 formed on the bottom surface of the substrate. Furthermore, the other end of the slot line 5 is connected to the output terminal 2 via a through hole 10. In this way, the capacitor 6 is placed on the board surface (top surface) where the strip line is located.

However, since the double-sided mounting method requires parts to be installed and mechanisms inspected independently on each side, the number of manufacturing steps is greater than that of the single-sided mounting method, and there are also various restrictions on mounting the board on the device. This is disadvantageous, such as the space occupancy rate worsening. Furthermore, since a coplanar line is used, there is a limit to miniaturization.
