Loaded power divider

Abstract

The invention discloses a loaded power divider. The loaded power divider comprises a coupling cavity, an input terminal, an output terminal, a coupling terminal and an isolation terminal, wherein the input terminal, the output terminal, the coupling terminal and the isolation terminal are communicated with the coupling cavity; the input terminal and the isolation terminal are located at a front end face of the coupling cavity, the coupling terminal and the output terminal are located at a rear end face of the coupling cavity, the isolation terminal is located at the right side of the input terminal, and the coupling terminal is located at the right side of the output terminal; and columnar bodies are arranged in the coupling cavity, are arranged into at least three rows along the direction of the front-rear axis of the input terminal, are arranged into at least two columns along the direction vertical to the front-rear axis of the input terminal, and are connected with an upper internal wall or lower internal wall of the coupling cavity. The power divider disclosed by the invention has over 59% relative operating bandwidth and has the characteristics of simple structure, small volume and low processing difficulty. The loaded power divider can be widely applied to the military and civilian fields of antenna arrays, phased-array radar, power synthesis, missile guidance, communications and the like.

Description

technical field [0001] The invention relates to a power divider. Specifically, it relates to a broadband two-way power splitter loaded with multiple columns, that is, a loaded power splitter. 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. Among them, due to the low isolation between the two output terminals of the first two devices, the mismatch of any output port will seriously affect the amplitude and ph...
