Abstract

Abstract: 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.

Key words: DFH, frequency synthesizer, DDS, DSP
