LO GENERATION USING PLLs
Analog Devices has a line of PLLs that can be used for
generating the LO signal. Table 4 lists the PLLs together with
their maximum frequency and phase noise performance.

The ADF4360 comes as a family of chips, with nine operating
frequency ranges. One can be chosen depending on the local
oscillator frequency required. While the use of the integrated
synthesizer might come at the expense of slightly degraded
noise performance from the ADL5385, it can be a cheaper
alternative to a separate PLL and VCO solution. Table 5 shows
the options available.

TRANSMIT DAC OPTIONS
The AD9777 recommended in the previous sections is by no
means the only DAC that can be used to drive the ADL5385.
There are other appropriate DACs depending on the level of
performance required. Table 6 lists the dual Tx-DACs that
Analog Devices offers.

All DACs listed have nominal bias levels of 0.5 V and use the
same DAC-modulator interface shown in Figure 31.
