摘　　要：文章结合模式匹配法和多模导纳矩阵理论,对波导型双工器进行分析设计,开发了一种快速精确的波导型双工器的设计程序,给出双工器设计中需要注意的关键技术问题。设计制作了含有弯波导结构的Ku波段双工器,理论与实测曲线吻合良好,为设计波导双工器提供了一种思路。Mode matching method and muhimode admittance matrix theory adopted, waveguide diplexer is designed and analyzed. Some key design problems are discussed, and a fast and rigorous procedure is put forward. A Ku band waveguide diplexer including waveguide bends is designed and fabricated, of which the theoretical results well agree with the experimental results. The method in this paper is effective and useful for the design of waveguide diplexers.
