POWER DIVIDER 3X3 FOR ONBOARD EQUIPMENT OF SPACECRAFTS Russian patent published in 2019 - IPC H01P5/18 

FIELD: physics.

SUBSTANCE: invention relates to UHF radio engineering, used, in particular, for use in onboard equipment of command-and-measurement system of spacecraft. Said technical result is achieved by using a power divider made on a dielectric substrate, on which there are three microstrip directional couplers made on connected lines, crossed once, and wherein two microstrip directional couplers have a transient attenuation of 3 dB, and a third microstrip directional coupler has a transient attenuation of 4.76 dB, wherein each of two ends of its connected lines located on one of its sides is connected respectively to the first and second identical sections of microstrip line (MSL) with one of the ends of the connected lines of microstrip directional couplers with transient attenuation of 3 dB, facing the third microstrip directional coupler, ends of other connected line segments, located on the other side of microstrip directional couplers with transient attenuation of 3 dB, are connected to each other by third section of MSL, length of which is more than total length of first and second sections of microstrip lines by value from 0.19 to 0.21 of wavelength at average frequency of operating range.

EFFECT: task of this technical solution is to increase transmission ratio by at least 1_25 dB, spacing of inputs and outputs on opposite sides of substrate, which, in turn, ensures rational arrangement of devices or elements of onboard equipment of command-and-measurement system.
