欠点を、有していた。Structure of a conventional example and its problems FIG. 1 shows a conventional example. The strip line 1 has a strip center conductor 2 on one side and a conductor substrate 3 on the other side, and a slot 4 is formed in the conductor substrate 3 at a position perpendicular to the strip center conductor 2. be. This slot-strip coupling circuit is generally well known and allows smooth coupling of electromagnetic fields. However, the coupling of the electromagnetic field is limited to the slot 4 when the strip line 1 is open.
The strip center conductor 2 is open in terms of direct current. Therefore, for example, when mounting the mixer diode 5 on the strip line 1 as shown in FIG. 2, it is necessary to provide a separate DC path circuit. The disadvantage is that the circuit is complicated because it requires several filter circuits.

ある。In this way, the electric field E is smoothly coupled from the s11nod electric field to the strinoso electric field. Therefore, even when the diode 5 is made 71 tangent, there is no need for a DC path or a choke circuit, the circuit becomes simple, and the circuit characteristics are not affected by the addition of a choke circuit or the like, resulting in good characteristics.

を接続できる。It is fixed by this strip. With this configuration, the coupling between the waveguide mode and the slot mode is electromagnetically smooth, as is well known in the past, as shown in Figure 7, which shows a part of the electric field IJ. Ru. Further, the electric field of the strip line 1 is distributed from the center conductor 2 toward the conductive substrate 3, and the electric field in the slot circuit is distributed between both ends of the slot 7, so that the electromagnetic coupling is smooth. A mixer diode can be connected to this strip line 1 as in FIG. 4.
したがって、導波管モードはスロットモードに結合し、
さらにスロワ１〜モードはス１−リップモードに結合す

能となる。Therefore, the waveguide mode couples to the slot mode,
Furthermore, since the thrower 1~ mode is coupled to the slip 1-slip mode, conversion coupling between the striso 1 line and the waveguide becomes possible.

線路は不平淳１形、平衡形のいずれにも使用できる。With this configuration, the conversion between a waveguide and a strip line, which was conventionally done via a coaxial line, can be done in 71 seconds.
Since no coaxial connectors or coaxial cables are used, conversion loss is small, and the entire circuit is small, lightweight, inexpensive, and easy to assemble. Therefore, when installing a mixer path on the strip line in a microwave receiver, the RF input signal from the receiving antenna is guided through a 2fJ wave tube, coupled to the strip line, and frequency converted there. The distance from the line to the mixer circuit is short, there is less signal loss, and the S/N of the receiver can be improved, and most of the signal processing circuits are constructed using strip lines. This has the effect of making the DC bus circuit unreliable when mounting a quiode. Note that the strip line can be used in either unbalanced type or balanced type.
