PRODUCT DESCRIPTION The AD810 is a composite and HDTV compatible, current feedback, video operational amplifier, ideal for use in systems such as multimedia, digital tape recorders and video cameras. The 0.1 dB flatness specification at bandwidth of 30 MHz (G = +2) and the different ...

transimpedance linearization circuitry. This allows it to drive video loads with excellent differential gain and phase perfor mance on only 50 mW of power. The AD8001 is a current feedback amplifier and features gain flatness of 0.1 dB to 100 MHz while offering differential gain and ph ...

Optical communication technology has been extensively developed over the last 50 years, since the proposed idea by Kao and Hockham [1]. However, only during the last 15 years have the concepts of communication foundation, that is, the modulation and demodulation techniques, been applied. This is pos ...

LTE-Advanced becomes a truly global standard for 4G cellular communications. Relay, as one of the key technologies of LTE-Advanced, can significantly extend the coverage, and improve the system throughput. LTE-A standards and tech- nologies were described in several recent books where the limited pa ...

PLL(Phase Locked Loop)： 为锁相回路或锁相环，用来统一整合时钟信号，使高频器件正常工作，如内存的存取资料等。PLL用于振荡器中的反馈技术。 许多电子设备要正常工作，通常需要外部的输入信号与内部的振荡信号同步。一般的晶振由于工艺与成本原因，做不到很高的频率，而在需要高频应用时，由相应的器件VCO，实现转成高频 ...
