摘　　要：在现代电子战中,接收机的工作环境往往比较恶劣,由各种模拟器件的温度漂移特性而导致接收机性能指标下降的现象普遍存在,对接收机进行温度补偿是必要的。文中介绍一种温度传感器DS1621芯片,具有较小的体积和较高的温度测量精度,基于I2C总线数据传输机制,在某型号信道化接收机温度补偿系统中得到的较好的应用,并给出了部分VHDL程序代码和实验结果。In modem electronic warfare, the receiver usually needs to work in bad environments, degraded performance of EW receiver caused by the temperature drifting of the analog devices is common. This paper introduces a thermometer and thermostat DS1621 which has small volume, high measurement accuracy and is supported by I2C bus transmission protocol. It worked well in the temperature compensation system of a channelized receiver. Parts of VHDL code program and experimental results are given.
