| Abstract: |
| This paper presents the result research of the application of a high performance DDS chip(AD9852). The DDS chip chosen for the frequency synthesizer is AD9852 recently made by AD Inc..The broad band spurious precedes 60dBc and the time of frequency agile is less than 200 ns. Based on the research result, the application of AD9852 in the frequency synthesizer and waveform synthesis frequency hopping communication systems is investigated. |
