POWER DIVIDER Russian patent published in 2019 - IPC H01P5/12 

FIELD: electrical engineering.

SUBSTANCE: invention relates to microwave engineering and can be used in systems of active phased antenna arrays, radio transmitters and other microwave devices and systems. Disclosed is power divider, comprising input arm connected via splitter from quarter-wave lengths of transmission line to output arms with connected to them star-connected ballast resistors. Said ballast resistors are made in the form of sections of transmission lines with losses in the form of a square, which is bisected by a metal-coated conducting strip with width equal to the width of a short-circuited loop connected to it, with length less than a quarter of the wavelength of the central frequency of the working range. Width of coupling section of each ballast resistor with corresponding output arm of power divider and common point of star of ballast resistors is equal to width of connecting sections of transmission line with wave resistance equal to output resistance of power divider. Sections of conjugation of ballast resistors with corresponding output arms and with common point of said star of ballast resistors are located symmetrically on opposite sides of each ballast resistor in form of a square.

EFFECT: technical result is increase in decoupling between output arms of power divider and direct transmission coefficient.
