一、引言随着科学技术的进步,固态化功率器件臼趋成熟, 越来越多的固态化发射机取代了传统的电子管发射机,设备的可靠性得到很大地提高。维护人员的注意力应及早从熟悉的电子管发射机转换到固态发射机上来,否则,遇到发射机故障,只能依赖厂家提供含有中间利润的零配件和人员往返差旅费的昂贵维修服务。 I. INTRODUCTION With the progress of science and technology, the solid state power device mortar become more mature, more and more solid state transmitter replaces the traditional tube transmitter, the reliability of the device has been greatly improved. Maintenance personnel should be diverted from familiar tube transmitters to solid-state transmitters as early as possible, otherwise transmitter malfunctions can only be relied on for manufacturers to provide expensive repair services with spare parts and personnel for intermediate travel and travel expenses.
