Embodiment Construction

[0023] The technical solutions of the invention will be described in detail below with reference to the accompanying drawings.

[0024] As shown in Figure 1, the multi-channel waveguide power combiner based on the E-surface porous expansion coupling structure is composed of multiple parallel rectangular waveguides and a porous coupling structure between the rectangular waveguides. Among them, one rectangular waveguide in the center is used as the main waveguide, and the other multiple rectangular waveguides are coupled waveguides. The long side of the coupled waveguide is parallel to the long side of the main waveguide, and the multiple coupled waveguides are arranged symmetrically about the center plane of the main waveguide. The rectangular waveguides are connected through a plurality of coupling apertures for power distribution. In this embodiment, adjacent rectangular waveguides are connected through five coupling apertures, wherein, looking from the input port port1 to th...

Abstract

The invention discloses a multipath waveguide power combiner based on an E-surface porous expansion coupling structure, and belongs to the technical field of microwave elements. The waveguide power combiner is composed of multiple paths of parallel waveguides and coupling structures among the waveguides. The multiple paths of parallel waveguides are arranged in parallel, the main path waveguide is in the middle, a port on one side of the main path waveguide is an input port, a port on the same side of each path of coupling waveguide and the input port is connected with a matched load, the other rectangular waveguides are symmetrically arranged along the two sides of the main path waveguide, and ports on the other sides of all the waveguides form power distribution or power synthesis ports. The waveguide power combiner is simple in structure and easy to process, has good passband characteristics, reflection characteristics and transmission characteristics, and is suitable for being used in a power combining and amplifying structure. The waveguide power device is subjected to two-stage cascade connection to form a two-dimensional waveguide power synthesis network, so that the combining efficiency is greatly improved.
