POWER DIVIDER Russian patent published in 2013 - IPC H01P5/12 

FIELD: electrical engineering.

SUBSTANCE: device consists of input arm connected through quarter-wave sections of transmission line to output arms with ballast resistors connected in-between; the latter ones are made as star-connected sections of lossy transmission line and to the common point of these sections short-circuited and earthed at the end stub is connected with length ℓ_s1, which is lesser than a quarter of the wavelength at the centre frequency of the operation range; at that short-circuited and earthed at the end stub is connected to each output arm and length of the stub is ℓ_s2 which is also lesser than a quarter of the wavelength at the centre frequency of the operation range.

EFFECT: improvement of coupling between output arms and matching at input and output of the power divider.
