一、引言人们对射频电弧并不陌生,并利用这个原理,成功地设计了超高频气体放电开关,用于雷达和其它设备中,然而,对电弧给无线电设备所带来的危害,只是近几年才开始比较详细的研究和探讨。随着卫星通信的迅猛发展,通信容量迅速增加,这样就要求地面发信机的工作频段向更 I. INTRODUCTION People are no strangers to radio-frequency arcs. Based on this principle, UHF gas discharge switches have been successfully designed for use in radar and other equipment. However, the harm caused by arcing to radio equipment is only near A few years before starting a more detailed study and discussion. With the rapid development of satellite communications, the rapid increase of communication capacity requires that the working frequency band of terrestrial transmitters should be more
