Abstract

The invention discloses an H-plane waveguide power divider. The H-plane waveguide power divider comprises a coupling cavity, an input port, an isolation port B, an isolation port C, an isolation port A, an output port A and an output port B, wherein the input port, the isolation port B, the isolation port C, the isolation port A, the output port A and the output port B are communicated with the coupling cavity; and the input port is located at a front end face of the coupling cavity, the isolation port A is located at a rear end face of the coupling cavity, the front end face and the rear end face are two mutually-symmetrical opposite faces of the coupling cavity, the isolation port B and the isolation port C are respectively located at the two sides of the input port, and the output port A and the output port B are respectively located at the two sides of the isolation port A. The H-plane waveguide power divider further has the characteristics of simple structure, small volume and low processing difficulty. The H-plane waveguide 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 splitter, in particular to a two-way power splitter with an equal-phase H-plane waveguide. 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 phase accuracy of power distribution. There is ...
