Abstract

The invention relates to a Ka-band low-consumption compact feed network. The network comprises a waveguide aperture converter, four E bent waveguides, an E-plane single T and two E-plane variation single T. The waveguide aperture converter is sequentially connected with the two E bent waveguides and the E-plane single T to form a 1: 2 combiner / distributor, and the waveguide aperture converter forms a waveguide input port. One ends of the other two E bent waveguides are connected with the two ends of the E-plane single T respectively, and the other ends are connected with the two E-plane variable single T respectively to form two 1: 2 combiners / distributors. The two E-plane variable single T form four output ports, and a quartered synthesizer / distributor from the waveguide aperture converter to the E-plane variation single T is formed through cascading. According to the invention, the synthesis / distribution function of the network is realized by the E-plane single T and the variation E-plane T, and the broadband characteristic of the T is realized by adjusting the matching mode.

Description

technical field [0001] The invention relates to a Ka-band low-consumption compact feeder network. It belongs to the field of microwave technology. Background technique [0002] The millimeter wave frequency band is currently the main frequency band for the development of military electronic technology, and is widely used in missile precision guidance, radar, secure communication, electronic countermeasures and testing technology. In order to obtain greater output power, it is necessary to use power synthesis technology in engineering to combine multiple active amplifiers in parallel to form an output. In the process of power combination, the combination method is an important factor to determine the high power output efficiency, combination complexity and other indicators. At present, the commonly used synthesis methods mainly include circuit synthesis of binary structure, free space power synthesis, and circuit synthesis of waveguide structure. Among them, the modeling a...
