Abstract

The invention belongs to the technical field of microwave communication, and particularly relates to a 32-channel waveguide E-plane power divider. The 32-channel waveguide E-plane power divider comprises two groups of 16-channel sub-power dividers which are in left and right mirror distribution, wherein each 16-channel sub-power divider comprises a first waveguide E-plane power divider and a second waveguide E-plane power divider; each first waveguide E-plane power divider is provided with a first E-plane waveguide directional coupler; a second E-plane waveguide directional coupler is arranged between each first waveguide E-plane power divider and the corresponding second waveguide E-plane power divider; a third E-plane waveguide directional coupler is connected with each first E-plane waveguide directional coupler and the corresponding second E-plane waveguide directional coupler; each E-plane waveguide directional coupler comprises a first rectangular waveguide and a second rectangular waveguide of an E-plane coupling structure; and each second rectangular waveguide is provided with a ladder stage for achieving a broadband phase compensation function. The 32-channel waveguide E-plane power divider has the advantages of a high broadband, a high power dividing ratio, a small amplitude fluctuation and good phase consistency; and the amplitude consistency and the phase consistency of an existing 32-channel power divider can be effectively improved.

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...
