MULTIPLEXER BASED ON A RING RESONATOR Russian patent published in 2022 - IPC H01P1/218 

FIELD: radio engineering.

SUBSTANCE: invention relates to microwave radio engineering, in particular to devices on magnetostatic waves, and can be used as a multiplexer. A multiplexer based on magnetostatic waves contains waveguide microwaves from an iron-yttrium garnet film forming two linear channels and having antennas for exciting and receiving magnetostatic waves, an annular resonator, a source of a controlling magnetic field, according to the invention, waveguide microwaves are made in the form of two rectangular structures, the long side of which is oriented along the entire long side of the substrate. The excitation antenna is located at one end of the microwave, and the reception antennas are located at the other three ends of the microwave, the ring resonator is made of a film of iron-yttrium garnet in the form of a rectangular closed circuit and is located with a gap above the microwaveguides. The opposite long sides of the rectangular contour are parallel to the long sides of the microwaveguides, and the width of the circuit is equal to the distance between the outer sides of the microwaveguides. The magnetic field of the source of the control magnetic field is directed tangentially along the plane of the microwaveguides, while the gap over the microwaveguides is d = 10 microns.

EFFECT: creation of an input-output multiplexer with the ability to control the operating modes of the device by changing the configuration of the distribution of the internal magnetic field with variations in the magnitude and direction of the external magnetic field.
