Research on S-band DDS/PLL Frequency Synthesizing Technology
Jin Shubo · Telecommunication Engineering · 2002
DDS is a kind of digital waveform synthesizing technology which has such good performance as short switch time, high frequency resolution and low phase noise. DDS is a good approach to be a reference of a frequency synthesizer. In this paper a DDS-driven-PLL frequency synthesizer for S-band telemetry receiver is described. The output characteristics of the DDS/PLL frequency synthesizer are also analyzed theoretically and the experiment result is presented.
