Intermediate lead-out scalable power combining method and system

Abstract

The invention discloses an intermediate lead-out scalable power combining method and system. The system comprises a number of power amplification modules, an E-plane T-type waveguide power combiner, a90-degree curved waveguide and a dual directional coupler. The power amplification modules are symmetrically distributed on both sides of the dual directional coupler. The dual directional coupler extends to both sides through the E-plane T-type waveguide power combiner, and each side is bent to a designated side through the 90-degree curved waveguide. The dual directional coupler is connected with a power amplification module through each input port of the E-plane T-type waveguide power combiner to form a scalable spatial symmetrical structure. Power combined signals generated by all power amplification modules are led out from the intermediate position.

Description

technical field [0001] The present disclosure relates to a method and system for mid-drop scalable power combining. Background technique [0002] Power distribution / synthesizers usually adopt a design method combining single-channel power amplification and multi-channel power distribution / combination technology to obtain high-power output signals. The power distribution / combination technology similar to the present invention mainly includes planar circuit power distribution / combination technology and waveguide-based spatial power distribution / combination technology. The planar circuit power distribution / combination technology mostly adopts the structure of multi-stage Wilkinson power divider cascading. As the number of power distribution / combination channels increases, the number of power divider stages increases, and the microstrip circuit loss also increases. The increase, resulting in a decline in the synthesis efficiency. Moreover, this solution has limited power capac...

Problems solved by technology

[0005] This technology adopts a binary power distribution / combination technology based on the E-plane T-shaped waveguide power division structure. As the number of power distribution / combination channels increases, the number of synthesis stages and synthesis paths will increase accordingly, so that the power The transmission loss of the distribution / combiner increases and the synthesis efficiency decreases. Therefore, in the microwave and millimeter wave frequency bands, this technology is usually applied to the power synthesis of signals within 8 channels. When the number of synthesis channels is more than 8 channels, this technology is usually not used.

[0006] This technology uses a plane-expanded power distribution / combination technology, which cannot make full use of the space volume, and the more the number of synthesis channels, the lower the space utilization rate, which is not conducive to the miniaturization and integration of the entire power distribution / combiner change
