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
ADL5375. There are other appropriate DACs, depending on the
level of performance required. Table 6 lists the dual TxDAC
offered by Analog Devices.

Figure 69. ADL5375-15 Single Carrier W-CDMA Composite and Symbol EVM
vs. LO Drive at 2140 MHz; Output Power = 10 dBm
The EVM exhibits moderate improvements with an increase in
the LO drive.
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.

All DACs listed have nominal bias levels of 0.5 V and use the
same simple DAC modulator interface that is shown in Figure 60.

Modulator
The
ADF4360-x
comes as a family of chips with nine operating
frequency ranges. Choose chips 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 ADL5375, it can be a cheaper alternative
to a separate PLL and VCO solution. Table 5 shows the options
available.
