一种基于L型结构的12路多路耦合器

12 RF Channels Multicoupler Based on L Type Coupling Structure

随着军用通信系统所面临的电磁环境愈发复杂以及军事指挥与控制对多路通信的需求与日俱增,作为多路通信系统关键设备的多路耦合器需要能够支持越来越多的射频信道数目。给出了一种工作在225~400MHz之间,能够提供12路射频信道的多路耦合器,采用L型耦合网络结合小范围调谐的可调滤波器实现,具有射频信道数目多以及易于加工的优点。

With the increasing of the interference in military communication systems and the units that should be controlled, the requirements of multicoupler with more and more channels have been proposed. This paper presented a preliminary scheme of 12 channels multicoupler operating from 225MHz to 400MHz which was constituted of L type coupling net and tunable filter with small tuning range. This mukicoupler have the ad- vantages of more radio channels and easy to be fabricated.
