微波统一测控系统中频开关网络的优化设计

Optimized Design of IF Switching Matrix in Unified Microwave TT＆C System

随着新研制的微波统一测控系统的功能扩展，对高频信道和多功能数字基带设备之间的中频开关网络设计提出了更高的要求。本文首先对某船载USB系统改造中的中频开关网络设计方案进行了介绍，并分析了该方案存在的不足。在此基础上，提出了对中频开关网络进行优化设计的若干方案，优化方案将使得系统功能更强大、设备使用更方便。

With functional expansion of the new generation TT＆C equipment, design of the IF Switching Matrix between the RF channel and the multi-purpose digital baseband equipment is more and more important. This paper introduces scheme of the IF Switching Matrix in ship-borne Unified S-band （USB） systems, and furthermore, the paper presents two schemes of optimized designs. The schemes make the system function more powerful and simplify operation.
