摘要
天线调配网络由阻抗匹配网络、滤波网络和防雷组件组成,常见的阻抗匹配网络有τ型、T型和π型三种。天调网络直接关系到高频信号能否获得最大功率输出,同时对发射机也起一定的保护作用。
Antenna matching network of medium-wave consists of matching network,filtering network and lightning protection circuit.The matching network has three types.The high-frequency signal could get the maximum output power connection with antenna matching network.The antenna matching network can protect the transmitter.
