FIELD: radio engineering, communication.
SUBSTANCE: directional coupler on magnetostatic waves contains a microwave-supported structure of an iron-yttrium garnet (YIG) film, antennas for exciting magnetostatic waves, placed on a gallium-gadolinium garnet substrate, and a layer of piezoelectric material equipped with metal electrodes for supplying an electrical voltage surface of the microwave-wave structure with the possibility of a piezomagnetic interaction, with the microwave-water structure being formed by three parallel microwave ovens of equal width, each of which has a rectangular shape and is installed with a gap with respect to each other to provide a mode of multimode communication, and the antennas are located at the ends of the microwave guides in such a way that the input antenna is located at one end of the median waveguide, one output antenna is located at the opposite end of the median waveguide, and the other two are located at adjacent ends of the peripheral waveguides.
EFFECT: creation of a three-channel microwave power coupler with control of the frequency range of the branch and the bandwidth.
