This paper defines well known and new versions of the design of power dividers/combiners whose decoupling resistors work in double-pole mode and which, instead of classical Wilkinson splitters, have low real loss at high enough divisible power level. Along with the known Gysel circuit, some new circuit versions of the Microstrip Power Dividers design are described, based on this circuit: broadband dividers and power dividers with unequal division between their output channels. Calculation and experiment results of the dividers of Gysel type having different power level at output channels equal to 3 dB and 11 dB, are presented. Antiphased decoupled power dividers and some new variants of broadband dividers are examined. This paper also offers new branch divider circuits of enhanced power. The main feature of their topology is that they have a matching segment at the input, and a wide segment in the centre of the topology. The paper presents amplitude-phase characteristics of both the in-phase and antiphased dividers into two channels, and the divider having a division factor of 3 dB. Calculation data of a 16 channel in-phase microstrip power divider made on a base plate of 2 mm thick, having dielectric conductivity equal to 9.8, are presented. P1-17-100-1 resistors of 50 are used in the circuit as decoupling resistors.
