Abstract:Broadcast transmitter is at the core position in broadcast transmission,and plays an important role in broadcast transmission,then the medium wave broadcast transmitter is of the uppermost priority. In view of this,based on the working principle of the power amplifier module,this paper analyzes the fault types of the power amplifier module of the medium wave broadcast transmitter easily occurred in operation,and deeply analyzes the causes of this phenomenon. At the same time,combined with the author’s many years of work experience,it discusses the corresponding fault resolution measures,aims at to improve the use efficiency of the power amplifier module of the medium wave broadcast transmitter,so as to better serves the broadcasting.

Keywords:broadcast transmitter;medium wave transmitter;power amplifier module
