New Equal Phase Power Splitter

Abstract

The invention discloses a novel equiphase power divider, which comprises a coupled cavity, an input end, an output end A, an output end B and an isolation end, wherein the input end, the output end A, the output end B and the isolation end are communicated with the coupled cavity; the input end and the isolation end are located on the front end face of the coupled cavity; the output end A and the output end B are located on the rear end face of the coupled cavity; the isolation end is located at the right side of the input end; the output end B is located at the right side of the output end A; loading bodies are arranged in the coupled cavity; the loading bodies are arranged along the direction which is vertical to the forward-backward axis of the input end into at least one line; height difference or / and width difference exists / exist between the adjacent loading bodies arranged along the direction of the forward-backward axis of the input end; and the loading bodies are connected with the upper inner wall or the lower inner wall of the coupled cavity. The power divider disclosed by the invention has the advantages that phases and amplitudes are consistent, and meanwhile, has the characteristics that the structure is simple, the size is small and the processing difficulty is low. The novel equiphase power divider disclosed by the invention can be widely used for military and civil fields of antenna array and phased array radars and power synthesis, missile guidance, communication and the like.

Description

technical field [0001] The invention relates to a power divider. Specifically, it relates to a novel two-way power divider loaded with multiple loading bodies, that is, a novel equal-phase power divider. Background technique [0002] The power splitter is a common component in modern microwave communication and military electronic systems. Due to its high power capacity and low insertion loss, waveguide power splitters are widely used. The two-way waveguide power splitter can be used alone, or can be connected in series to form a multi-way power splitting network, which is used in the fields of phased array radar, antenna array, and power combination. The existing two-way waveguide power splitter mainly includes E-plane T-shaped branch, H-plane T-shaped branch, waveguide magic T, H-plane waveguide crack bridge, etc. Due to the low isolation between the two output terminals of the left two devices, the mismatch of any output port will seriously affect the amplitude and pha...
