Abstract

The invention provides a power division network with high power capacity. The network adopts an air strip line structure, the air strip line structure comprises an upper cover plate, a central conductor layer and a lower cover plate, and the upper cover plate and the lower cover plate are made of metal materials and are used as the ground of an air strip line. The central conductor layer is located between the upper cover plate and the lower cover plate, the distance between the central conductor layer and the upper cover plate is equal to that between the central conductor layer and the lowercover plate, and media at the two sides are both air. The central conductor layer is a metal sheet, an outer shell is a structural member of the air strip line, and all parts are connected and fixed.The central conductor layer is not in contact with the outer shell, and connectors are welded on each port of the central conductor layer and is used for signal transmission. According to the power division network, the structure of a the short-circuit branch line with the length being one fourth of the wavelength is additionally arranged in an air strip line power divider, so that the capabilityof a planar transmission line power divider for withstanding higher power is greatly improved.

Description

technical field [0001] The invention relates to the field of microwave feeding networks, and designs a power division network with high power capacity based on air striplines, which can realize low loss, high power capacity and easy integration characteristics at the same time. Background technique [0002] Increasing the transmission power of the system can significantly increase the range of radar and improve the interference effect in electronic countermeasures. Therefore, higher power microwave systems have broad application prospects in radar, electronic countermeasures and other fields. As the peak power continues to increase, the system's requirements for the performance of the subsequent transmission and launch systems are also gradually increasing. As an important component of the transmission and transmission system, the power distribution network can withstand high power directly determines whether the high-power system can achieve efficient energy transmission. ...
