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

FIELD: antenna equipment.

SUBSTANCE: invention relates to microwave engineering and can be widely used in active phased antenna array systems, radio transmitting devices and systems using microwave power. Disclosed is a power divider comprising an input arm connected through quarter-wave transmission line segments to output arms, between which there are ballast resistors, made in the form of transmission line segments with losses and connected to a star, to common point of which connected short-circuited loop with length less than quarter wavelength of central frequency of operating range, characterized in that said sections of transmission line with losses are made non-uniform in form of circle, wherein width of coupling section of each ballast resistor to corresponding output arm of power divider is equal to width of connecting section of transmission line with wave resistance equal to output resistance of power divider, width of coupling section of each ballast resistor with short-circuited loop is equal to width of this loop, the above sections of conjugation of ballast resistors with corresponding output arms and with short-circuited loop are located symmetrically on both ends of diameter of each ballast resistor in form of a circle.

EFFECT: increased isolation between output arms of power divider and expansion of device pass band by this parameter.
