Problems solved by technology

However, more size parameters make the optimization process very difficult, resulting in longer simulation optimization time or failure to obtain results that meet the design requirements
When designing multiple devices with different N values ​​at the same time, it is more difficult to design and optimize, which brings difficulties to realize any N-channel power distribution / combination

Abstract

The invention discloses a design method of a multipath radial power distributor / synthesizer, and relates to the technical field of millimeter wave power distribution / synthesis. According to the radial power divider / synthesizer based on the coaxial waveguide, a function relation expression between the outer radius length b and the path number N of the coaxial waveguide in the radial power divider / synthesizer based on the coaxial waveguide is obtained through simulation and numerical analysis, so that the initial size information of the device can be directly calculated through the working wavelength lambda and the path number N of the device, the radial power divider / synthesizer meeting the requirements can be quickly and simply designed, parameters required to be optimized during device design are reduced, and the design and optimization time is efficiently saved.

Description

technical field [0001] The present invention mainly relates to the technical field of millimeter wave power distribution / synthesis, in particular to a coaxial waveguide-based TE 01 A rapid design method for modular multi-channel power divider / combiner. Background technique [0002] In the millimeter wave band, the output power of a single power amplifier chip is very limited, but in engineering practice, power output of tens of watts or even higher is often required, which usually requires the use of power combining technology to complete. On the contrary, in some practical engineering application systems that do not require too much power input, a power divider is needed to distribute the large power source into the system in proportion, so it has become a hot topic to concentrate the power synthesis and distribution functions on one device Research. When designing such devices, waveguide-based space power combining technology is often adopted because of its high combinin...
