Fractional-N PLL with Integrated VCO
25 - 3000 MHz
HMC830LP6GE Application Information
Large bandwidth (25 MHz to 3000 MHz), industry leading phase noise and spurious performance, excellent noise floor
(<-170 dBc/Hz), coupled with a high level of integration make the HMC830LP6GE ideal for a variety of applications; as
an RF or IF stage LO, a clock source for high-frequency data-converters, or a tunable reference source for extremely
low spurious applications (< -100 dBc/Hz spurs).

Using the HMC830LP6GE with a tunable reference as shown in Figure 25, it is possible to drastically improve spurious
emissions performance across all frequencies. Example shown in Figure 21 graph shows that it is possible to have
spurious emissions < -100 dBc/Hz across all frequencies. For more information about spurious emissions, how they
are related to the reference frequency, and how to tune the reference frequency for optimal spurious performance
please see the “Spurious Performance” section of Hittite PLL w/ Integraged VCOs Operating Guide. Note that at very
low output frequencies < 100 MHz, harmonics increase due to small internal AC coupling. Applications which are
sensitive to harmonics may require external low pass filtering.
