摘要
调频广播发射技术的核心载体源自广播发射机,其中国内又主要以中波发射机为主。因此,研究中波广播发射机的故障是确保广播发射工作有序开展的先决条件,具有重要的现实意义。本文以国内广播电台应用广泛的DAM-50KW中波广播发射机为例,对维护功放模块的损坏问题和解决检测方法展开分析和总结。
FM radio emission technology is the core of the carrier from the radio transmitter,of which the main medium wave transmitter.Therefore,research on medium wave radio transmitter failure is ensuring that radio emission is a prerequisite for the orderly conduct of the work of, has the important practical significance. This article to domestic radio applications to a wide range of DAM-50 KW medium wave radio transmitter, for example,on maintenance of power amplifier module damage problems and solving method for the detection of expansion analysis and summary.
