QM2010-6000

USB RF Synthesizer Module

25 MHz – 6 GHz output

Figures 1 and 2 illustrate the performance difference between integer and fractional mode when tuning to 3
GHz with a 50 MHz reference. In order to tune to 3 GHz with a 50 MHz reference, the user can either operate
in integer mode with a reference divider of 1, or in fractional mode. Figure 1 depicts the phase noise
differences between 3 GHz in fractional mode vs. integer mode with a reference divider of 2, whereas Figure 2
shows the spurious content difference in a 50 MHz span between the two modes of operation.
