Description of the invention

The subject of the invention is a microwave double insulator.

Hitherto known microwave double insulator consisting of a first insulator made of ferrite coupled lines, a T junction and a matching circuit, and a second identical insulator connected to the first insulator, the first and the second longitudinally facing each other.

Known microwave double insulators are characterized by a different location of the ferrite in the ferrite coupled lines, either by the opposite magnetization of the ferrite coupled lines, or by the location of each insulator on a different substrate layer, or by the location of the single insulators next to each other.

A microwave double insulator consisting of a first insulator based on ferrite coupled lines, a T-junction and a matching circuit, and a second identical insulator connected to the first insulator, the first and the second longitudinally opposite each other, according to the invention, the right line of the first insulator it is connected to the left line of the second insulator, and the matching circuit is based on lumped and planar elements or on coaxial loads. The microwave double insulator is made in the technique of microstrip lines or in the technique of slotted lines.

Thanks to this structure, the invention has the following advantages: both sections of ferrite coupled lines are magnetized in unison, and it is also possible to reduce the size of the entire double insulator, it is also possible to eliminate bends of microstrip tracks and to implement the system entirely on a dielectric substrate.

The invention is explained in more detail in an embodiment and in the drawing in which Fig. 1 shows a block diagram of a microwave double insulator, and Fig. 2 shows the measured frequency characteristics of this insulator.

P r z k ł a d I

The microwave double insulator consists of the first insulator I and the second insulator II, which are made on the basis of ferrite coupled lines, and the T 4 junction and matching circuit 3. The first insulator I and the second insulator II are arranged longitudinally opposite to each other. The right line 2 of the first insulator I is connected to the left line 1 of the second insulator II. The matching circuit 3 is realized on the basis of coaxial elements. The microwave double insulator is made in the technique of microstrip lines.

P r z x l a d II

The double microwave insulator is made as in Example 1, except that the matching circuit 3 is based on lumped and planar elements. The microwave double insulator is made in the slotted line technique.
