带信号导件的微波频段合路器

Microwave frequency band combiner with signal conductors

Abstract

The utility model discloses a microwave frequency band combiner with signal conductors, which comprises two waveguide cavities, a coupling board connected with the two waveguide cavities, and the signal conductors which are respectively sheathed on the same ends of the upper waveguide cavity and the lower waveguide cavity and are used for transferring the signal direction, wherein the coupling board is provided with two coupling slot holes which are symmetrical on the longitudinal axis of the coupling board and are used for coupling signals between the two waveguide cavities, the top wall of each waveguide cavity is respectively provided with a matcher used for finishing the signal matching of the waveguide cavities, the matchers of the two waveguide cavities are symmetrical on the coupling board, each signal conductor is a hollow piece, and the inner cavity of each signal conductor is provided with a step-shaped wall surface. In the microwave frequency band combiner with the signal conductors, as the coupling slot holes, the step-shaped matchers in the waveguide cavities, the steps in the inner cavities of the signal conductors and the like are integrally designed, and the combiner can be more flexibly and conveniently adjusted. The utility model has the absolute advantages in bandwidth and coupling energy, thus greatly improving the property.
