超小型UHF RFID读写模块的设计

Design of a miniature UHF RFID reader&writer module

采用PHYCHIPS公司的UHF频段前端收发芯片PR9000作为核心芯片,并结合电源管理模块,设计实现了一款超小型UHF RFID读写模块,在工作频率840~960 MHz范围内,接收灵敏度小于-70 dBm,发射功率-13-10dBm可调,功耗小于5 W。UHF RFID读写模块具有尺寸小、灵敏度高和低功耗的优点,可嵌入手机、打印机等移动终端,具有广泛的应用领域。

Based on the core module PR9000,which is the radio frequency transceiver chip of the company PHYCHIPS,combining the power management module,has developed a UHF RFID readerwriter module realizing miniature.Under the frequency range from 840 to 960MHz,receiveing sensitivity under-70dBm,transmit power-13 to 10dBm,which can be adjusted by software,power consumption under 5W.UHF RFID readerwrite module has the advantage of small size,high sensitivity and low power consumption,which can be embedded to mobile phone,printer,etc.has the extensive application domain.
