摘要 LMDS(本地多点分配业务 )是一种微波宽带技术 ,是解决“最后一公里”问题成本较低、功能较丰富的一种。本文设计了一种可用于LMDS中的采用加方形脊T形结的微波矩形波导双工器。介绍了矩形波导E面金属膜片滤波器的设计方法 ,这种滤波器的金属膜片可通过蚀刻等方法加工 ,加工精度高 ,成本低。 Local Multipoints Distribution Services (LMDS) is the broadband wireless technology. Design of a microwave rectangular waveguide diplexer for LMDS is presented. A ridged T junction is proposed as diplexing manifold. E plane metal septum filter is utilized in the diplexer design. The filters allow low cost manufacturing by accurate and inexpensive metal etching or milling technique.
