摘要
文章介绍了设计全固态中波广播发射机三频共塔网络的关键部分——预调网络和阻塞网络,并结合实际介绍了江门中波台的三频共塔的设计思路,同时分析了采用带通耦合网络作为匹配网络的优越性。
This paper introduces the key elements of the design of the three frequency common tower network of all solid state medium wave broadcasting transmitter-premodulation network and blocking network,and introduces the design idea of the triple frequency common tower in this platform.At the same time,it introduces the superiority of adopting the band-pass coupled cooperative matching network.
