一、概述中波发射机天馈线调配网络的设计好坏,是关系到发射设备能否可靠运行的关键。特别对于全固态发射机天馈系统在多频干扰环境下的设计是很有讲究的,特别值得推敲和研究。设计时,首先要准确的测出天线在使用频率上的特性阻抗和边带阻抗,一般边带阻抗与载波频率阻抗变化率
I. Overview The design of an antenna feeder deployment network for a medium wave transmitter is the key to the reliable operation of the transmitting equipment. Especially for all-solid-state transmitter antenna feeding system in multi-frequency interference environment is very particular about the design, in particular, worth considering and research. Design, we must first accurately measure the antenna in the use of frequency characteristic impedance and sideband impedance, the general sideband impedance and carrier frequency impedance change rate
