RADIO

无线电广播是以无线电波为传输广播节目载体的广播方式。世界公认的首次电台播音是1920年11月2日美国威斯汀豪斯公司在匹茨堡的KDKA电台播出哈定当选总统。此后,苏联、英国以及中国等许多国家纷纷建立了广播电台。

  • 射频集成电路设计John Rogers(RADIO Freq

    RADIO Frequency Integrated Circuit Design I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog integrated circuit designers in the past workedon applications at low enough frequency that microwave issues did not arise.As a consequence, they were adept at lumped parameter circuits and often notcomfortable with circuits where waves travel in space. However, in order todesign RADIO frequency (RF) communications integrated circuits (IC) in thegigahertz range, one must deal with transmission lines at chip interfaces andwhere interconnections on chip are far apart. Also, impedance matching isaddressed, which is a topic that arises most often in microwave circuits. In mycareer, there has been a gap in comprehension between analog low-frequencydesigners and microwave designers. Often, similar issues were dealt with in twodifferent languages. Although this book is more firmly based in lumped-elementanalog circuit design, it is nice to see that microwave knowledge is brought inwhere necessary.Too many analog circuit books in the past have concentrated first on thecircuit side rather than on basic theory behind their application in communications.The circuits usually used have evolved through experience, without asatisfying intellectual theme in describing them. Why a given circuit works bestcan be subtle, and often these circuits are chosen only through experience. Forthis reason, I am happy that the book begins first with topics that require anintellectual approach—noise, linearity and filtering, and technology issues. Iam particularly happy with how linearity is introduced (power series). In therest of the book it is then shown, with specific circuits and numerical examples,how linearity and noise issues arise.

  • 无线电干扰 RADIO Susceptibility

      Abstract: Engineers often wish that RADIO susceptibility (RS) or RADIO immunity could be cured with an antibiotic, a vaccine, or someform of cure-all. Unfortunately, solving the RS problem is not that easy. Indeed, the laws of physics apply. In this article we discusssources of RS. We also offer tips and hints to protect systems, power supplies, printed circuit boards (PCBs), and electroniccomponents from RADIO frequency interference.

  • GPRS(General Packet RADIO Service)是通用分组无线业务的简称。GPRS是GSM Phase2.1规范实现的内容之一

    GPRS(General Packet RADIO Service)是通用分组无线业务的简称。GPRS是GSM Phase2.1规范实现的内容之一,能提供比现有GSM网9.6kbit/s更高的数据率。GPRS采用与GSM 相同的频段、频带宽度、突发结构、无线调制标准、跳频规则以及相同的TDMA帧结构。因此,在GSM系统的基础上构建GPRS系统时,GSM系统中的绝大部分部件都不需要作硬件改动,只需作软件升级。
