Embodiment

The utility model detailed structure, application principle, effect and effect with reference to accompanying drawing 1-4, are explained through following execution mode.

The utility model divides input port to connect outside input source by three merits of broadband three power splitters; Two merits that its three output ports connect three broadband two power splitters are respectively divided input port; Each output port of back three connects two merits of another one broadband two power splitters respectively and divides input port, becomes the structure that goes out into 12.

Aforementioned broadband three power splitters divide input port, three merits to divide isolation resistance, three three merits to divide propagation and transformation section, output armatine, output port second and output port third to constitute by three merits; Wherein three merits divide input port, three merits to divide propagation and transformation section, output armatine, output port second and output port third to be the microband printing line; Three merits are divided between input port and three output ports respectively has one three merit to divide the propagation and transformation section; Wherein up and down two three merits to divide the propagation and transformation section to be sinusoidal rectangle wavy, and waveform is relative; It is wavy that middle one three merit divides the propagation and transformation section to be end to end S shape; Article three, to divide the corner cut crest of propagation and transformation section and corner cut trough be transformer section to three merits; Two three merits are divided three intersegmental close section middle parts of propagation and transformation to be provided with three merits and are divided the impedance conversion node up and down, and divide isolation resistance to connect through three three merits respectively.

Aforesaid broadband two power splitters divide input port, two merits to divide isolation resistance, two two merits to divide propagation and transformation section, output port one and output port two to constitute by two merits; Wherein to divide input port, two merits to divide propagation and transformation section, output port one and output port be the microband printing line to two merits; Two merits divide input port and output port one, two of output ports respectively to have one to be two wavy merits of sinusoidal rectangle and to divide the propagation and transformation section; Article two, two merits divide the waveform of propagation and transformation section relative; Its corner cut crest and corner cut trough are that two merits are divided transformer section; Three close section middle parts between the two are provided with two merits and divide the impedance conversion node, and divide isolation resistance to connect through three two merits respectively.
