FIELD: SHF equipment. ^ SUBSTANCE: invention is deigned for distribution of input signal with preset ratio of powers, it can be used in various radio engineering devices to form amplitude-phase distribution in transceiving phased arrays. Given microstrip divider with unequal division of power has input arm for supply of SHF energy to which first and second quarter-wavelength sections intercoupled by means of resistor and connected through first and second quarter-wavelength transformers to first and second outputs of divider. Divider is supplemented with quarter-wavelength stub connected to third output of divider, on one hand, and to matched load, on the other hand. This stub is coupled electromagnetically through gap to one of quarter-wavelength transformer. Value of gap is chosen from condition of obtainment of required power division ratio and of obtainment of wave resistance of formed coupled lines equal to wave resistance chosen for coupling of quarter-wavelength transformer. ^ EFFECT: realization of three-channel power divider with unequal division, without any substantial increase of dimensions as compared with double channel divider, potential for realization of larger power difference across outputs of divider. ^ 1 dwg |
