摘要
差分跳频技术以其跳速高、抗干扰能力强等特点,是今后短波跳频通信的发展方向。本文主要介绍一种差分跳频系统中的频率合成器设计方案,选用直接数字频率源DDS芯片AD9854作为核心器件,采用DSP芯片TMS320VC5402控制DDS的方式输出发射频率。实际测试结果表明:频率转换速率快,波形质量好。
With the character of anti-jamming and high speed, the differential frequency hopping is the development direction of shortwave frequency hopping communication. This paper introduces a frequency synthesizer design for DFH. The DDS chip AD9854 is adopted as the core component, the DSP chip TMS320VC5402 is adopted to control DDS chip to produce the wave of transmit frequency. The actual test results show that wave have an advantage of high conversion speed and good waveform.
