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 is chosen, depending on the local
oscillator frequency required. While the use of the integrated
synthesizer may come at the expense of slightly degraded noise
performance from the ADL5370, it can be a cheaper alternative
to a separate PLL and VCO solution. Table 5 shows the options
available.

TRANSMIT DAC OPTIONS
The
AD9779
recommended in the previous sections of this data
sheet is by no means the only DAC that can be used to drive the
ADL5370. There are other appropriate DACs, depending on the
level of performance required. Table 6 lists the dual Tx-DACs
offered by Analog Devices.

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