Problems solved by technology
Especially in the miniaturization design of multi-channel power division network, the phase compensation circuit will greatly increase the device size and design difficulty
At the same time, the working bandwidth of the H-plane waveguide crack bridge is relatively narrow
The E-plane waveguide ring bridge (RingHybrid or Rat-RaceHybrid) and the H-plane waveguide ring bridge are also limited due to their relatively large volume and narrow operating bandwidth, especially in the miniaturization design of the multi-channel power distribution network. Bridges are rarely used

The invention discloses an H-plane cross-shaped power splitter, which includes a coupling cavity, an input end connected to the coupling cavity, an output end A, an output end B and a matching end. The device can have a left-right symmetrical structure, and the angles between the input end, output end A, output end B and the matching end at the center of the interface with the coupling cavity and the upper end surface of the coupling cavity are all less than or equal to 30 degrees. Wherein, the width of the input terminal, the output terminal A and the output terminal B is greater than its height, and the height of the matching terminal is greater than its width. The maximum dimension of the coupling cavity in a certain direction on the upper end face of the coupling cavity is smaller than 3 / 4 of the free space wavelength corresponding to the highest operating frequency of the H-plane cross-shaped power divider. The invention has the characteristics of simple and compact structure, broadband, low processing and debugging cost, good isolation between output terminals, high amplitude and phase precision between output terminals, etc. Used in military and civilian fields such as radar, missile guidance, and communications.
Description
technical field [0001] The invention relates to a power divider, in particular to a compact broadband waveguide power divider with good amplitude and phase consistency. 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-branch, H-plane T-branch, waveguide magic T, H-plane waveguide crack bridge, E-plane waveguide ring bridge (RingHybrid or Rat-RaceHybrid) and H-plane Waveguide ring bridge, etc. Among them, due to the low isolation between the two output terminals of the first two devices, the mismatch of...
