Abstract: A 16-channel power combiner with W-band spatial hybrid waveguide structure is designed, which combines the advantages of waveguide radial power combiner and waveguide binary combiner, the 16-channel diverter waveguide ports are divided into two 8-channel radial composite structures which are placed symmetrically, two 8-channel radial structures are combined into a single path through a double coaxial probe power splitter, and each 8-channel radial structure, the impedance matching between the coaxial waveguide and the splitter waveguide is realized by means of trapezoidal tapered structure. The simulation results show that the total structure insertion loss is less than 0.5 dB and the return loss is better than 16 dB in the range of 88-102 GHz. The utility model has the advantages of high synthesis efficiency, low loss and compact structure.
