摘要
在现代社会,基于多频共馈共塔工程造价低,建设用地少的特点,在电台、广播中的应用已十分普遍。本文主要是研究分析两频共馈共塔的匹配网络并实时进行匹配网络的理论设计。整个电路全部由电抗值随频率变化的网络元件(L、C)构成,通过并串、串并电路满足网络匹配的要求,达到预期的目标。
In modern society, the application of multi frequency common feed tower with its feature of low cost and low construction land is very commonly used in radio and broadcasting station. This paper mainly studies and analyzes the matching network of two frequency common feed and common tower, and carries out the theoretical de- sign of the matching network in real time. The whole circuit is made up of network components （ L, C） which are reactance varying with frequency, and can meet the requirements of network matching through parallel and serial to parallel circuits, and then achieves the expected goal.
