DF100 kW PSM短波发射机是我国短波广播事业中的重要机型,其工作载波频率在3.2~26.1 MHz。由于其在高频频率的范围内工作,且机箱中有各种变压器、电源和电路板,所以,在发射机工作的过程中会产生许多高频率的电磁辐射。主要分析了发射机在抗电磁干扰方面所采取的措施,并且将这些措施应用在其他高频设备中也具有一定的借鉴意义。

The DF100 kW PSM short wave transmitter is an important type of our shortwave broadcasting in the work, the carrier frequency in the 3.2~ 26.1 MHz. Because of its work in the range of high frequency within the chassis, and there are various transformer, power supply and a circuit board, therefore, in the process of transmitter work will produce many high frequency electromagnetic radiation. The main analysis of the transmitter is taken in the anti-electromagnetic interference measures, and these measures application also has a certain significance in other high-frequency equipment.
