The Development Of Ultra-wideband Microwave Power Splitter

Power divider is the indispensable component of microwave equipments such as phased-array radar, multi-channel relay communication system. Broadband power divider such as a phased-array radar's microwave equipment, key parts of its size and weight are subject to strict limitations. Therefore, the development of small size, light weight, low cost and good performance of the broadband power divider is not only the practical engineering needs, but also because of phased array radar in spaceborne and airborne systems are an increasingly wide range of applications,Makes this study is particularly necessary and urgent. Therefore, this paper's work has great practical significance.This paper mainly for ultra-wideband microwave divider summary of the development process. The main thesis is as follows:1. Introduced the ultra-wideband microwave power divider background to the project; right at home and abroad ultra-wideband microwave power divider developments are briefly reviewed, and briefly introduced the topic of research content and technology indicators;2. Described the basic theory of microwave power divider, including the Wilkinson power divider theoretical analysis, the choice of circuit structure, etc.;3. For the two kinds of ultra-wideband microwave divider structure, and given their design process simulation, simulation curves and design layout;4. Pairs of ultra-wideband microwave divider developed in the structure and process has been improved, given two kinds of ultra-wideband microwave divider final research results;5. Compare the developing product with foreign products and have a conclusion of the developing task.
