Data Sheet
EVALUATION BOARD
Populated RoHS-compliant evaluation boards are available
for evaluation of the ADL5375. The
exposed paddle on the underside. This exposed paddle should
be soldered to the board for good thermal and electrical grounding.
The evaluation board is designed to minimize LO feedthrough
to RFOUT through PCB by placing LO block on the underside.
And it can be configured to allow differential LO driving through
balun or direct interfacing to the PLL evaluation board. It also
reserves component pads in its LO path to accommodate a
harmonic filter. One side placement of baseband inputs is to
interface directly to DAC evaluation board. The
evaluation board also includes an RF driver amplifier. The
modulator output can be measured directly at the MOD_OUT
SMA connector. Alternatively, by removing R1, and installing a

0 Ω resistor in the R2 pad, the modulator’s output can be fed to
the RF driver amplifier.
The evaluation board ships, installed with an
amplifier (400 MHz to 2700 MHz RF driver amplifier). This
device requires external matching components (C100 and C101)
and is tuned by default for operation from 1805 MHz to 2170 MHz.
For details on tuning component values for other frequencies,
please refer to the ADL5320 data sheet (the driver amplifier section
of the
Evaluation Board). For higher frequency operation, the ADL5320
should be replaced by the ADL5321, which is specified to operate
from 2.3 GHz to 4 GHz. If a broadband matched device is desired,
the
can be used.
