作为功率传输的"纽带",天馈线系统是整个中波发射系统中重要的一环,而中波天线调配网络系统的带宽是衡量天馈系统的重要指标之一.带宽能够影响到很多指标,同时也有很多因素会影响带宽.基于此,重点介绍如何在设计中波天线调配网络中利用埃尔米特对称、边频电抗中和术、低Q值和多级匹配等技术实现宽带化.
Research on Wideband of Medium Wave Sky Modulation Network
As the "link" of power transmission, the antenna feeder system is an important link in the whole medium wave transmission system, and the bandwidth of the medium wave antenna deployment network system is one of the important indexes to measure the antenna feeder system. Bandwidth can affect many indicators, and there are many factors that can affect bandwidth. Based on this, this paper focuses on how to use Hermite symmetry, side frequency reactance neutralization, low Q value and multistage matching to realize broadband in the design of medium wave antenna allocation network.
