浅析DX数字调幅发射机射频功放模块

摘要

Currently digital all solid state am medium wave transmitter in gradually replaced electron tube transmitter, Chongqing Radio launch pad that build a station introduced American Harris DX-10 and DX-50 type all solid state digital MW Transmitter, in use process, often appear some problems, are summarized experience in maintenance, the failure rate of higher RF power ampliifer module principle are introduced in detail, and gives examples of maintenance.%目前数字化全固态调幅中波发射机在逐渐取代电子管发射机，重庆广播发射台建台时引进了美国哈里斯的DX-10和DX-50型全固态数字中波发射机，在使用过程中，经常出现一些问题，现在总结维修经验，对故障率较高的射频功放模块的原理进行详细介绍，并给出了维修实例。
