随着通信事业的发展和电化教学的推广,调频广播发射机做为自办广播节目、学习外语的辅助工具进行推广。调频广播造价远远低于语音室、覆盖面大,在校园内任何地方都可以方便地学习外语,收听广播,并且投资省、见效快。我们研制生产的VDF系列调频广播发射机包括立体声,单声道各种类型,从0.1W至100W各种功率等级,具有电路先进,使用可靠、造型美观、轻便,系列化、通用化等优点,尤其在稳频技术、高频功率放大等电路上独树一枝,受到国内
With the development of communication and the popularization of electrified teaching, FM radio transmitters are promoted as auxiliary tools for broadcasting programs and learning foreign languages. FM radio costs far lower than the language lab, coverage, anywhere in the campus can easily learn foreign languages, listen to radio, and investment in the province, quick. We develop and produce VDF series of FM radio transmitters, including stereo, mono various types, from 0.1W to 100W various power levels, with advanced circuits, reliable use, handsome in appearance, light, serial, universal and so on, Especially in the frequency stabilization technology, high-frequency power amplifier and other circuits alone, by domestic
