 The invention relates to a microwave technique and can be used; t1 an uncoupling source of electromagnetic oscillations and a load.

The purpose of the invention is to increase return loss and ensure the possibility of changing the direction of the valve effect.

FIG. 1 shows the construction of a ferrite resonant valve; in fig. 2 - section aa in figure 1,

Ferrite resonance contains grounded plates 1 with coaxial holes 2, through which the central conductor 3, two loops, filled in the form of the first 4 and the second 5 segments of the coaxial line, the central strip - the steep conductor 6, the middle part of which is as a part of a ring, elements 7 of a conjugate control by the electric length of the plumes, the first 8 and second 9 ferrite inserts, and also a magnetic system (not shown).

Ferrite resonant valve operates as follows.

When the SBS-C signal is applied to the valve input at the locations of the first 8 and second 9 ferrite liners, initial installation of equal electric lengths of the first 4 and second 5 segments and further concurrent control of these elements using elements 7 creates a microwave magnetic field. polarization. In this case, one component of the microwave magnetic field creates - with a current flowing through the central strip conductor 6, and the other is equal to it, but shifted in time and space by 90 - with currents flowing through the center conductor 3 of the first 4 and second 5 segments. rotation of the microwave vector magnetic field is such that such a signal will not interact with the first 8 and second 9 ferrite liners. As a result, the microwave signal goes to the output of the ferrite resonant valve with almost no losses.

As a result, when the magnetizing field is equal to the resonant, the output of the RF signal is wobbly (5 ferrite liners are in the first and second and practically does not flow to the input connector of the ferrite resonant valve. The direction effect of the valve effect can be changed by a quarter of wavelengths using elements 7 of the electric lengths of the first 4 and second 5 segments without changing the value of the magnetizing field, but only changing to the opposite direction of rotation of the microwave vector deleterious floor at the positions of the first 8 and second 9 ferrite inserts, equivalent change in the input and output resonant valve seats ferrite.

 The invention relates to a microwave technique and can be used; t1 an uncoupling source of electromagnetic oscillations and a load. The purpose of the invention is to increase return loss and ensure the possibility of changing the direction of the valve effect. FIG. 1 shows the construction of a ferrite resonant valve; in fig. 2 shows section A-A in FIG. The ferrite resonance contains grounded plates 1 with coaxial holes 2, through which the central conductor 3, two loops executed in the form of the first 4 and the second 5 segments of the coaxial line, the central conductor 6, the middle part of which is made a part of the ring, elements 7 of the conjugate control of the electric length of the plumes, the first 8 and second 9 ferrite inserts, and also the magnetic system (not shown). The ferrite resonant valve operates as follows. When the SBS-C signal is applied to the valve input at the locations of the first 8 and second 9 ferrite liners, initial installation of equal electric lengths of the first 4 and second 5 segments and further concurrent control of these elements using elements 7 creates a microwave magnetic field with a circular field. customization. In this case, one component of the microwave magnetic field is created by the current flowing through the central strip conductor 6, and the other is equal to it, but shifted 90 in time and space by currents flowing through the central conductor 3 of the first 4 and second 5 segments. rotation of the microwave vector magnetic field is such that such a signal will not interact with the first 8 and second 9 ferrite liners. As a result, the microwave signal arrives at the output of the ferrite resonant valve with almost no losses. When applying the same microwave signal to the output connector of a ferrite resonant valve, the direction of rotation of the microwave magnetic p: ol vectors at the locations of the first 8 and second 9 ferrite liners 8 and 9 and 92 is reversed. As a result, when the magnetizing field is equal to the resonant, the power of the RF signal is absorbed (first and second ferrite liners in the first and second, and practically does not reach the input connector of the ferrite resonant valve. elements 7 of the electric lengths of the first 4 and second 5 segments without changing the value of the magnetizing field. In this case, only the opposite direction of rotation of the microwave vector is changed The first floor at the locations of the first 8 and second 9 ferrite liners, which is equivalent to changing the places of entry and exit of a ferrite resonant valve. Invention A ferrite resonant valve containing two grounded plates and a central strip conductor, forming a symmetrical strip line, two loops, to one the ends of which are connected to the elements of the conjugate control of their electrical lengths, the first and second ferrite liners, transversely magnetized and installed one above the other on both sides from the central strip conductor, characterized in that, in order to increase the return loss and to enable the valve effect direction to be changed, the loops are made in the form of the first and second sections of a coaxial line of the same electrical length, formed by two coaxial holes in corresponding grounded plates, through which The entered central wire is missed; a part of the central strip conductor, as well as the first and second ferrite liners are made in the form of ring parts the same x angular dimensions of each of ferrite pads located on the inner side of the respective ground plane, wherein the central conductor, the first and second ferrite vkladshsh and middle portion of the strip conductor arranged concentrically.
