DF100 kW PSM型短波发射机高频干扰问题的分析与处理

Analysis and Treatment of High Frequency Interference of DF100 kW PSM Shortwave Transmitter

作为传统的传媒平台,现阶段广播行业在大众的日常生活中依然占据非常关键的位置,并扮演着重要的角色。作为国内短波广播场景应用较多的机型之一,DF100 kW PSM短波发射机的不断发展进步对整个广播事业而言是十分关键和重要的。但由于该发射机长期工作在较高频段范围,导致极易产生大量高频高能量的电磁辐射干扰,对整个发射机的正常工作和性能发挥造成了严重的影响。从不同的方面对高频干扰产生的原因进行了分析,并有针对性地提出了相应的抗干扰策略。

As a traditional media platform,the broadcasting industry still plays an important role in the daily life of the public.As one of the models which are widely used in domestic short wave broadcasting scene,the continuous development and progress of DF100 kW PSM short wave transmitter is very critical and important for the whole broadcasting industry.But because the transmitter works in a higher frequency range for a long time,it is easy to produce a lot of high frequency and high energy electromagnetic radiation interference,which has a serious impact on the normal work and performance of the whole transmitter.This paper analyzes the causes of high frequency interference from different aspects,and puts forward the corresponding antiinterference strategies,which has strong reference significance.
