CONTROLLED BY ELECTRIC FIELD POWER DIVIDER ON MAGNETOSTATIC WAVES WITH FILTRATION FUNCTION Russian patent published in 2019 - IPC H01P1/22 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, particularly to signal dividers. Microwave signal microwave power divider at magnetostatic waves comprises microwave-based structure based on iron-yttrium garnet (IYG) film placed on substrate, input and two output ports connected to microstrip antennas for excitation and reception of magnetostatic waves in microwave-wave structure, source of control magnetic field. Microwave guide structure is made in form of T-shaped branching, base of which is connected to microstrip antenna of input port, and side arms – with microstrip antennas of output ports. At sections between branching and microstrip antennae of output ports there are means for providing piezomagnetic interaction in film IYG, made in the form of piezoelectric film with electrodes connected to source of electric field, and control magnetic field is directed at a tangent to film IYG.

EFFECT: imparting microwave signal filtration functions to the power divider on the MSW, while providing the possibility of controlling frequency characteristics by means of magnetic and electric fields independent of the power of the input signal.
