A Wideband DDS Module for High-Speed Frequency Synthesizer 박 범 준․ 박 동 철* Beom-Jun Park․Dong-Chul Park*


In this paper, a wideband DDS module covering the frequency range from 0.5 to 1.1 GHz was designed and fabricated. The clock frequency of the DDS was selected 2.4 GHz in order for 600 MHz output bandwidth. Multiple spurious cancelling signals having same amplitude and 180 ° phase difference compared to the spurious were created at the additional path and added to the output signal within DDS for the spurious performance improvement. The fabricated DDS module showed better spurious performance than the commercia
