Problems solved by technology

[0006] But the disadvantages are as follows: (1) The three-dimensional structure adopted by this technology increases the processing difficulty, and the assembly is complicated, and the production cost is high; (2) This technology uses a coaxial transmission line as the transmission medium of the multi-channel power distribution and synthesis section. As the operating frequency enters the 40GHz or higher frequency band, the loss of the coaxial transmission line becomes larger, which will seriously affect the synthesis efficiency of the synthesizer

Abstract

The present invention relates to the technical field of millimeter wave power distribution synthesis, and particularly relates to a novel composite function gradient millimeter wave waveguide power distribution synthesizer. The distribution synthesizer comprises N-level allocators and symmetrically arranged synthesizers with the same amount and connected with each other through a power amplification chip; the allocator matrices are connected with 2N-2 allocator daughters through a one-level two-way waveguide power divider; and the synthesizer matrices are connected with 2N-2 synthesizer daughters through a one-level two-way waveguide power combiner. The distribution synthesizer disclosed by the present invention is applicable to a millimeter wave band, and has advantages such as a wide wave band, a large capacity, high efficiency, lower consumption, and the like.

Description

technical field [0001] The invention relates to the technical field of millimeter-wave power distribution and synthesis, in particular to a novel composite function gradient millimeter-wave waveguide power distribution synthesizer. Background technique [0002] Power distribution synthesizers usually adopt the design method of combining single-channel power amplification and multi-channel power distribution and synthesis technology to obtain high-power output signals. Current power distribution and combination technologies mainly include planar circuit power distribution and combination technology and waveguide-based spatial power distribution and combination technology. The technical features and disadvantages are as follows: [0003] 1. The traditional planar circuit power distribution and synthesis technology mostly adopts the structure of multi-stage Wilkinson power divider cascading. As the number of power distribution and synthesis channels increases, the number of st...
