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.

Description

Technical field [0001] The invention relates to the field of microwaves, in particular to a multi-channel power distribution and synthesis structure. Background technique [0002] Microwave and millimeter wave solid-state power amplifiers, as an important part of microwave and millimeter wave radar, guidance, communication, and testing systems, have become an important research direction in the field of microwave and millimeter waves. [0003] In modern microwave and millimeter-wave solid-state power amplifiers, due to the limitations of the power amplifier chip by its own semiconductor physical characteristics, as well as heat dissipation, manufacturing process, and impedance matching issues, single-chip amplifiers often fail to meet the high-power application requirements in actual projects. Therefore, in order to meet the needs of high-power communications, testing and other systems, it is necessary to use multiple power amplification and then power synthesis to increase the out...

Problems solved by technology

This power distribution / synthesis technology is the closest realization scheme to the present invention. Its structural advantages are small size, high space utilization rate, no need for probe coupling transformation to microstrip circuit, and reduced transmission loss. The disadvantage is passive power distribution. The synthesis part and the active amplifier component part cannot be separated as independent modules, and can only be assembled and disassembled as a whole, and the processing precision is high, the assembly process is cumbersome, the structure is too closed, the heat dissipation performance is poor, and the chip is easily burned
