一款Ku/Ka双频段分频器的设计

Design of a Ku/Ka Dual-band Frequency Divider

民用和军用卫星通信领域中大量使用双频段、多频段共用天线,双频段共用馈源技术具有重要的工程使用价值,其中分频器是双/多频段馈源网络系统的核心部件,主要实现分频的功能,其性能直接决定了整个馈源网络系统的性能指标。分频器可以提取公共端口上多个工作频段的信号,并将他们分别提供给相应频段的端口。本文介绍了一种比较系统的设计方法,使分频器的设计更加快速有效。

The civilian and military satellite communication use lots of the dual band/multi-band antenna, dual-band shared feed technology has important engineering value, the frequency divider is the core component in the dual / multi-band feed network system, it mainly realizes the function of frequency division, it's performance determines the performance of the feed network system. The frequency divider can extract the signals of a plurality of working frequency bands on a common port, and each of the frequency bands is provided to the corresponding frequency bands. In this paper, a design method of the system is introduced, which makes the design of frequency divider more rapid and effective.
