现代微波通信系统通常采用由适当互连的窄带滤波器组成的滤波子系统，其目的是分离(或组合)分配在频谱(信道)的不同段中的几个RF信号。这种子系统通常被称为“多路复用器”。实际上，存在几种类型的多路复用器，它们在总体拓扑上可能会有明显的不同。这些类可以分成两个非常一般的系列：流形耦合多路复用器和星形结多路复用器。在过去一期的IEEE微波杂志中，对前一系列的设计技术进行了概述，因此本文将重点介绍星型结多路复用器。
Modern microwave communication systems generally employ filtering subsystems composed of narrowband filters suitably interconnected, whose purpose is the separation (or combination) of several RF signals allocated in different segments of the frequency spectrum (channels). Such subsystems are generally referred to as “Multiplexers.” Actually, several classes of multiplexers exist, which may differ, even noticeably, in overall topology. These classes can be grouped in two very general families: manifold-coupled multiplexers and star-junction multiplexers. In a past issue of IEEE Microwave Magazine, an overview of the design techniques for the former family was given, so this article will focus on the star-junction multiplexers.
