Wideband frequency synthesizers are used in many different applications, such as radars, telecommunications and others. Radar parameters are dependent on the synthesizers phase noise. A general flow-chart of a hybrid frequency synthesizer based on direct digital and direct analog synthesis methods that uses a high-speed digital-to-analog converter (DAC) in special operating modes to increase the operating frequency is presented in this paper. The noise characteristics of a hybrid synthesizer with a DAC operating in two modes are simulated.
