Abstract

The invention belongs to the technical field of microwave communication, and in particular relates to a 32-way waveguide E-plane power divider. The present invention includes two sets of sixteen-way sub-power splitters distributed in left and right mirror images; each sixteen-way sub-power splitter includes a first waveguide E-plane power splitter and a second waveguide E-plane power splitter; the first waveguide E-plane power splitter The first E-plane waveguide directional coupler is set at the power divider, and the second E-plane waveguide directional coupler is set between the first waveguide E-plane power divider and the second waveguide E-plane power divider; the third E-plane waveguide directional coupler Connect the first E-plane waveguide directional coupler and the second E-plane waveguide directional coupler; each E-plane waveguide directional coupler includes a first rectangular waveguide and a second rectangular waveguide with an E-plane coupling structure, and the second rectangular waveguide is provided with It is used to realize the step section of broadband phase compensation function. The invention has the advantages of high broadband, high power split ratio, small amplitude fluctuation and good phase consistency, and can effectively improve the amplitude consistency and phase consistency of the current 32-way power splitter.

Description

technical field [0001] The invention belongs to the technical field of microwave communication, and in particular relates to a 32-way waveguide E-plane power divider. Background technique [0002] The power divider is an antenna feeder device widely used in modern communications. Traditional power dividers include Wilkinson, E-plane waveguide, H-plane waveguide, etc. The Wilkinson power splitter has a low profile and has the advantage of miniaturization, but the low power capacity and large dielectric loss of the microstrip transmission line limit its application in high-power requirements. The waveguide power splitter is favored for its excellent characteristics such as low loss, high power capacity and wide transmission bandwidth, and is widely used in high-power systems such as radar and satellite. In the waveguide power divider: the H-plane power divider is distributed by the wide side of the waveguide, and the lateral size is relatively large, so it has the defect that...
