摘　　要：使用分立元件搭建的新型超高频读写器方案设计灵活,相比于一些读写器使用集成芯片,这种方法可以大大缩减设计成本,且其性能毫不逊色于市面上大多数读写器。读写器系统包括了软件和硬件两部分,在这里重点讲述其硬件电路的设计并同时介绍软件系统的实现。系统的硬件主要包含了基带信号的处理部分和射频前端,在处理器上配套运行的软件系统主要包括了协议处理、编解码、硬件系统的控制以及与上位机的通信。A design of UHF RFID （Radio-frequency Identification） Reader is detailed which uses discrete components for lower cost compared to using a reader IC. A reader system often comprises hardware and software as we all know. In this paper, we emphasize on the design of hardware and present you the architecture of software. The part of hardware design mainly consists of digital processing part, RF transmission and receiver. For the hardware,a matched software is designed which consists of protocol processing, the whole system control and communication with a computer, and is running on a MPU （Micro Processing Unit） chip.
