The paper outlines design problems in cellular communication systems using fast frequency hopping. It describes some technical approaches to the problem solution. A new randomization technique reducing discrete spectral components in DDS is also offered for frequency synthesizer of the cellular system using fast frequency hopping.

Keywords: direct digital synthesizer, randomization technique, phase locked loop.
