中文摘要： 在现代军事和民用通信系统中，多工器是实现多部收发信机共用一部天线的关键部件，对于减少天线数量和提高通信质量具有重要意义。传统的微波多工器往往体积庞大、通道数紧张、调谐速度慢，工作模式简单、设计周期漫长，成为制约微波系统通道扩展和布局简化的瓶颈。随着通信系统的日趋复杂和软件无线电的日益发展，亟需研究多工器的尺寸紧缩与自适应跳频技术。本项目采用广义空间映射法与参数提取技术，深入研究微波多工器的电路综合理论和结构设计方法，力图解决多工器的机辅设计与调试、小型化和快速跳频问题，主要研究内容包括：（1）微波多工器的广义空间映射法与电路综合理论；（2）微波多工器的参数提取和机辅调试技术；（3）基于多模、多频、多层和有耗技术的小型化多工器；（4）基于可重构和电调技术的跳频微波多工器。

英文摘要： In the modern military and commercial communication systems, multiplexer is a key component which realizes that an antenna can be used by two or more transmitters or receivers, it is significant to reduce the number of antennas and improve the communication quality. Conventional microwave multiplexer has many disadvantages, such as huge volume, limited channels, slow tuning rate, single operating mode and long design period, which restricts the channel extending and arrangement simplification of microwave system. Since the communication has become complicated and software defined radio has achieved great development, it’s urgent to investigate the size-reducing and adaptive frequency-hopping technology of multiplexer. In this project, we have a deep research in the circuit synthesis theory and structure design method of microwave multiplexer, making use of the generalized space mapping method and parameter-extracting technology, which can resolve the computer-aided design and tuning，miniaturized and fast frequency-hopping problem of multiplexer,it mainly includes: (1) Generalized space-mapping method and circuit synthesis theory for microwave multiplexer;(2)Parameter extraction and computer-aided tuning technology for microwave multiplexer;(3) Miniaturized multiplexer based on multi-mode, multi-band, multi-laye
