Abstract

The invention discloses a pi-type five-port E-surfaced power divider which comprises a coupling cavity, an input port communicated with the coupling cavity, an isolated port B, an isolated port C, an output port A and an output port B, wherein the input port is located in the front end face of the coupling cavity, the output port A and the output port B are located in the rear end face of the coupling cavity, the front end face and the rear end face are two opposite faces of the coupling cavity, the isolated port B and the isolated port C are respectively located on two sides of the input port, and the output port A and the output port B are respectively located on two sides of the axis of the coupling cavity. The pi-type five-port E-surfaced power divider is capable of covering waveguide full band width. When a plurality of pi-type five-port E-surfaced power dividers are connected in series to form a large-scale network, the main structure can be symmetrical and asymmetrical. An equiamplitude and isophase power divider with the symmetrical structure has the advantages that theoretical phase difference and amplitude difference between two output ends are zero which is far less than the phase difference of a generally used H-surfaced waveguide fissure bridge.

Description

technical field [0001] The invention relates to a power divider, in particular to a broadband five-port 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. 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 a good isolation between the...
