MULTI-CHANNEL WAVEGUIDE POWER DIVIDER Russian patent published in 2009 - IPC H01P5/12 

FIELD: physics.

SUBSTANCE: invention is related to electronic equipment, in particular, to multi-channel waveguide power dividers, and may be used in creation of multi-channel superheterodyne receivers mostly of millimeter wave length range and in SHF metering equipment. Multi-channel waveguide divider comprises main wave guide and two rows of branched waveguide channels in its opposite narrow walls arranged in the form of rectangular wave guides sections shortened at the ends, longitudinal axes of which are parallel to longitudinal axis of the main wave guide. In common part of narrow walls of main and every section of rectangular wave guide there is communication element in the form of rectangular slot. Lengths of slots in branched channels are different and are determined by specified ratio. In E-planes of the first and second row rectangular wave guides sections there are dielectric substrates installed, in every of which within the limits of every section of rectangular wave guide there are slot and coplanar lines arranged as orthogonal to each other, one or two ends of which are outputs of power divider. Coplanar line in every section of rectangular wave guide may be shortened at one end and is a matched line of transmission in direction of its both ends.

EFFECT: provision of even division of power in branched channels in specified frequency band, higher manufacturability of divider manufacture, in convenience and simplicity of divider arranging in composition of complex systems, and also in possibility to double number of divider outlets without increase of its weight and dimensions.
