VHDL/FPGA/Verilog 小数分频技术解决了锁相环频率合成器中的频率分辨率和转换时间的矛盾, 但是却引入了严重的相位噪声, 传统的相位补偿方法由于对Aö D 等数字器件的要求很高并具有滞后性实现难度较大。$2 调制器
小数分频技术解决了锁相环频率合成器中的频率分辨率和转换时间的矛盾, 但是却引入了严重的相位噪声,
传统的相位补偿方法由于对A&ouml D 等数字器件的要求很高并具有滞后性实现难度较大。$2 调制器对噪声具有整形的功
能, 因而将多阶的$2 调制器用于小数分频合成器中可以很好地解决他的相位噪声的问题, 大大促进了小数分频技 ...
无线通信 折叠PIFA天线在蓝牙的应用
蓝牙是一种支持设备短距离通信(一般是10 m之内)的无线电技术，能在包括移动电话、PDA、无线耳机、笔记本电脑等众多设备之间进行无线信息交换，工作频段是工业、科研、医疗(2.4～2.483 GHz)全球通信自由频段，目前已经广泛应用在移动通信设备中。天线是蓝牙无线系统中用来传送电磁波的重要器件，目前尚无法整合 ...

书籍 Radio System Design for Telecommunication
This book provides the essential design techniques for radio systems that
operate at frequencies of 3 MHz to 100 GHz and which will be employed in
the telecommunication service. We may also call these wireless systems,
wireless being synonymous with radio, Telecommunications is a vibrant indus-
try, ...
书籍 Radio Wave Propagation
One of the prerequisites for the development of telecommunication services is the
understanding of the propagation of the waves, either acoustic, electromagnetic,
radio or light waves, which are used for the transmission of information.
In this work, we shall limit ourselves to the study of radio wa ...
书籍 Advanced+Chipless+RFID
The author’s group has developed various chipless RFID tags and reader architectures
at 2.45, 4–8, 24, and 60 GHz. These results were published extensively in the form of
books, book chapters, refereed conference and journal articles, and finally, as patent
applications. However, there is still ro ...
技术资料 射频测试电缆的关键参数选择
射频测试线缆是每一个射频微波工程师都要接触的东西，很多人在选择一条射频测试线缆时，只提出需要用到多少GHz频率，要什么接头。但其实除了这两点，线缆还有很多其他 更关键的参数，比如插损、相位稳定度、幅度稳定度等指标，这些指标可能会直接影响产品指标的测试结果。 ...
