SOLDERING INFORMATION
The AD8349 is available in a 16-lead TSSOP package with an
exposed paddle. The exposed paddle must be soldered to the
exposed metal of a ground plane for a lowered thermal
impedance and reduced inductance to ground. This results in a
junction-to-air thermal impedance (θ
JA
) of 30°C/W. If multiple
ground planes are present, the area under the exposed paddle
should be stitched together with vias.
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.

Analog Devices also offers the ADF4360 fully integrated
synthesizer and VCO on a single chip that offers differential
outputs for driving the local oscillator input of the AD8349.
This means that the user can eliminate the use of the balun
necessary for the single-ended-to-differential conversion. The
ADF4360 comes as a family of chips with six operating
frequency ranges. One can be chosen depending on the local
oscillator frequency required. The user should be aware that
while the use of the integrated synthesizer might come at the
expense of slightly degraded noise performance from the
AD8349, it can be a much 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 of this data
sheet is by no means the only DAC that can be used to drive the
AD8349. There are other DACs that are appropriate, depending
on the level of performance required. Table 6 lists the dual Tx-
DACs that ADI offers.
