文摘The technology or DDS-driven PLL is introduced and a new scheme of frequency synthesizerwhich is suitable for SW SFH/MFSK System is presented in this paper. Based on the spedal requirement ofSW communication, a model or the scheme is given and the results show that the frequency synthesizer hassmall frequency insteval (≤0. 1 Hz), short switch pierod(<200 ms) and high frequency stability as crystaloscillator.
