1.引言 微波功率分配器和开关在微波工程上都有许多应用,但两者不能兼容。W.L.Teeter等人提出的任意分配比的功率分配器,无论是在性能上,还是在结构上都比早期工程上应用的有很大的提高。但仍然不能实现不同状态下功率分配比的快速转换。文中也未给出完整的分析。本文介绍的任意功率分配比的微波开关(以下简称“开关”),与文献[1]给出的不全相同,它是分配器和开关的组合。它具有可变的任意功率分配比和在不同状态(如宽、窄波束功率分配比;发射、接收等不同状态)下快速转换的多功能组件。 “开关”是作为某种机载雷达的波束转换开关而研制的,因为原铁氧体波束转换开关,
1. Introduction Microwave power dividers and switches have many applications in microwave engineering, but the two are not compatible. The power divider of any distribution ratio proposed by W.L.Teeter et al. Is greatly improved in performance and structure compared with the earlier engineering applications. But still can not realize the rapid conversion of the power distribution ratio in different states. The article also did not give a complete analysis. This article describes the power distribution ratio of any microwave switch (hereinafter referred to as “switch”), and given in [1] the same incomplete, it is a combination of splitter and switch. It has a variable arbitrary power distribution ratio and in different states (such as wide and narrow beam power distribution ratio; transmitting, receiving and other different state) rapid conversion of multi-functional components. “Switch” is developed as a kind of airborne radar beam switch, because the original ferrite beam switch,
