Abstract

The invention discloses an I-type five-port E-surface power divider which comprises a coupling cavity and an input port, an isolation port B, an isolation port C, an output port A and an output port B communicated with the coupling cavity, wherein the input port (1), the isolation port A (2) and the isolation port B are located on the front end surface of the coupling cavity (6); the output port A is located on the left end surface of the coupling cavity; and the output port B (5) is located on the right end surface of the coupling cavity (6). The I-type five-port E-surface power divider disclosed by the invention has the characteristics of simple structure, small volume and low processing difficulty. An equal-amplitude equal-phase power divider covering full bandwidth of waveguide can be realized through the invention. Particularly when multiple power dividers are connected in series to form a large-scale network (10-1,000 paths), the main structure can be classified into a symmetric type and an asymmetric type; and when a symmetric structure is adopted, the major characteristic of the formed equal-amplitude equal-phase power divider is that theoretical phase difference and amplitude difference between two output ends are zero and the phase difference is far less than the phase difference of a common H-surface waveguide slot bridge.

Description

technical field [0001] The invention relates to a power splitter, in particular to a broadband five-port 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 cracked bridge, E-plane waveguide cracked 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. ...
