The invention provides an ultra-
wide band multi-path coaxial power distribution synthesis
structure based on a high-
odor oval function curve. A coaxial gradual change
structure based on the high-
odor oval function curve is adopted, an input
signal enters a high-
odor oval function curve coaxial gradual change structure from an input end coaxial connector, and is distributed onto a
circular disc in a uniform-amplitude and same-phase way, multi-path coaxial probes in uniform distribution are led out from the edge of the
circular disc to be coupled onto a plurality of independent
amplifier assemblies corresponding to the multi-path coaxial probes for respectively carrying out power amplification, each
coaxial probe adopts a step cylinder structure with the wider upper part and the narrower lower part, the amplified multi-path
signal is synthesized and output through a structure completely identical to a power splitter structure. The ultra-
wide band multi-path coaxial power distribution synthesis structure has the advantages that the difficult problem of high-power synthesis of the ultra-wide
frequency band is solved, the high-odor oval function curve coaxial gradual change structure is adopted, in addition, the step
coupling probe conversion is carried out, the
signal energy high-efficiency distribution and synthesis of the ultra-wide
frequency band are realized, the structure is compact and symmetrical, the heat
radiation performance is good, the high-degree
modular design is adopted, the
processing and the
assembly are simple, and the reliability is high.
