The arbitrary multi-channel power distributor / synthesizer comprises a coaxial input waveguide, N transition waveguide structures and N standard rectangular waveguides, wherein a working mode of the coaxial input waveguide is the TE01 mode, one end of the coaxial input waveguide serves as an input / output port, the N transition waveguide structures are arranged at the other end of the coaxial input waveguide at equal intervals along the side wall, and the other end of eachtransition waveguide structure is connected with the corresponding standard rectangular waveguide to form N output / input ports. According to the arbitrary multi-channel power distributor / synthesizer,the coaxial waveguide is adopted as the input waveguide, equal-amplitude power division and high power synthesis efficiency of multiple paths of signals are achieved, meanwhile, reactance matching isformed between the coaxial waveguide and the rectangular waveguide through the transition waveguide structure, and the working bandwidth of the multi-path power divider / synthesizer is effectively broadened; in addition, the structure is simple, the number of components is small, integrity is good, and machining is easy.

Generally, there are two main ways to obtain high power of microwave and millimeter waves: vacuum electronic power devices and solid-state power devices; electric vacuum devices include traditional klystrons and traveling wave tube power amplifiers. It is difficult to produce in batches, and the working voltage is high, the volume is large, the reliability is low, the life is short, and the linearity is low, which limits the application of electric vacuum devices in the field of microwave and millimeter waves; the solid-state power amplifier has the advantages of small size and light weight , low working voltage and good reliability, but as the frequency rises to the millimeter-wave frequency band, the size of the solid-state chip becomes smaller, and the output power of a single chip is limited due to factors such as semiconductor physical characteristics, processing technology, impedance matching, and chip heat dissipation. , cannot meet the requirements of high power system

[0003] In practical applications, although electric vacuum devices can provide high power, due to the excessive power of a single tube, power distribution is required, which affects the integration of vacuum devices; on the contrary, solid-state devices, the output power provided by a single chip is limited and requires power combining.
