基于CC1020的高灵敏度低空探空接收机设计

Design of low-altitude sounding receiver for high sensitivity based on the CC1020

针对当前低空探空接收机存在灵敏度低、便携性差、高功耗等多方面的缺点,本文介绍了一种新型接收机:以CC1020为核心收发芯片,可提高接收灵敏度至-118dBm,并采用C8051F320为控制芯片,完成数据处理、USB通信及供电。大大提高了系统的便携性及数据可靠性。文中对该接收机的工作原理和方式进行了分析,给出了设计思路和硬件电路。

In view of the disadvantage of current low-altitude sounding receiver, which is low sensitivity, poor portability,and high power consumption and so on. The paper introduces a new type of receiver that the core transceiver chip based on CC1020, enhanced the receiving sensitivity to-118 dBm; the MCU C8051F320 is used as the controlling chips to complete the data processing USB communication and power supply; the system power is supplied from the USB, to improve the portability and the reliability greatly, the paper makes an analysis of working principle and method, giving the design ideas and hardware circuit.
