Abstract

The invention discloses a rectangular waveguide ladder which comprises a base, an upper cover plate, an input rectangular waveguide, an output rectangular waveguide and at least one medium transition section arranged between the input rectangular waveguide and the output rectangular waveguide, wherein the input rectangular waveguide and the output rectangular waveguide are both arranged between the base and the upper cover plate, each medium transition section is of a cylinder shape, and the upper end face of each medium changeover portion is connected with the upper cover plate and the lower end face of each medium changeover portion is connected with the base. The rectangular waveguide ladder has the advantages that problems of processing difficulty in high-frequency sections and high processing cost in the prior art are solved, and processing cost of components is reduced.

Description

technical field [0001] The invention relates to a rectangular waveguide ladder for a microwave and millimeter wave circuit, in particular to a rectangular waveguide ladder capable of connecting rectangular waveguides with different heights and widths. Background technique [0002] Due to its advantages in power capacity and transmission loss, waveguides have been widely used in the field of low-loss or high-power microwave and millimeter wave transmission. In radar systems, power combining systems and other occasions, it is often necessary to form various complex circuits by microwave and millimeter wave guides. Existing waveguide devices are generally assembled from multiple parts. Due to the different sizes of the various parts, a waveguide transition structure is used during the assembly process. At present, the most common waveguide transition structures are linear gradient, curved gradient and stepped structure. Among them, the linear gradient structure is simple and ...
