Description

technical field [0001] The invention belongs to the technical field of terahertz power synthesis, and in particular relates to a multi-layer structure terahertz radial power distribution / combination network. Background technique [0002] The wavelength of terahertz waves is shorter than that of microwave and millimeter waves, and the size of terahertz circuits is smaller. But the current terahertz system, compared with the microwave and millimeter wave system, its overall module cannot achieve the same proportional volume scaling as the wavelength. One of the reasons is the problem of circuit architecture and module assembly, too many complex and redundant waveguide flanges / The use of connectors additionally increases the module volume. [0003] For radial power synthesis, the current technology is to separately manufacture mode converters, radial power distribution / combiners and N power amplifier modules, and the input / output ports of each module are equipped with wavegui...

AI Technical Summary

Problems solved by technology

Since the number of modules is positively correlated with N, resulting in a large number of modules, the assembly is extremely cumbersome, and the volume is large and the space utilization rate is low

The above-mentioned circuit architecture suitable for microwave and millimeter wave frequency bands is not conducive to the high integration of the system and the miniaturization of modules, and it is difficult to apply to the terahertz frequency band
