嵌入式综合 CC1110:RF 片上系统解决方案
The CC1101 is a low-cost sub- 1 GHztransceiver designed for very low-powerwireless applications. The circuit is mainlyintended for the ISM (Industrial, Scientific andMedical) and SRD (Short Range Device)frequency bands at 315, 433, 868, and 915MHz, but can easily be programmed foroperation at other ...
嵌入式综合 lpc2292/lpc2294 pdf datasheet
The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum ...
无线通信 RF Power Amplifiers for Wireless Communications, Second Edition
When I started writing the first edition of RF Power Amplifiers for Wireless Communications,some time back in 1997, it seemed that I was roaming a largely uninhabitedlandscape. For reasons still not clear to me there were few, if any, otherbooks dedicated to the subject of RF power amplifiers. Rig ...

无线通信 MAX7060的ASK_FSK的ISM射频发射机
Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry ca ...
无线通信 ZigBee无线传感网络的路由协议研究
 为满足无线网络技术具有低功耗、节点体积小、网络容量大、网络传输可靠等技术要求,设计了一种以MSP430单片机和CC2420射频收发器组成的无线传感节点。通过分析其节点组成,提出了ZigBee技术中的几种网络拓扑形式,并研究了ZigBee路由算法。针对不同的传输要求形式选用不同的网络拓扑形式可以尽大可能地减少系统成本。 ...
无线通信 UHF读写器设计中的FM0解码技术
 
 针对UHF读写器设计中,在符合EPC Gen2标准的情况下,对标签返回的高速数据进行正确解码以达到正确读取标签的要求,提出了一种新的在ARM平台下采用边沿捕获统计定时器数判断数据的方法,并对FM0编码进行解码。与传统的使用定时器定时采样高低电平的FM0解码方法相比,该解码方法可以减少定时器定时误差累积的影 ...
无线通信 错误观念妨碍电量计在无线手机中的应用
Abstract: Most hand-held products lack accurate battery-charge monitors ("fuel gauges") because of the misconception that an accurate fuel gauge is difficult to achieve. This article debunks the myths and discusses how to accurately monitor charge at all temperatures, charge and discharge rates, and ...
