EVAL_ADDIFFAMP_15 Datasheet, PDF (3/4 Pages) Analog Devices – Differential Driver Evaluation Board

When not using a transformer, bypassing the transformer is a
simple matter of shorting the appropriate jumpers. Clearly,
when using a transformer, it is a good idea to verify that the
associated jumpers are open.
SMA INPUT/OUTPUT CONNECTORS
The inputs and outputs have edge-mounted SMA connectors
for straightforward connection to coaxial cables. The recom-
mended connector type is Johnson Components™ part number
142-0701-801, or equivalent.
OTHER COMPONENTS
The components discussed in this data sheet pertain mostly to
traditional amplifier topologies. There are footprints provided
for a number of other components on the board to allow the
EVAL-ADDIFFAMP
user to be more creative than the traditional designs. Clearly, a
component labeled as a capacitor need not be a capacitor
provided it fits the user’s application circuit and to the footprint
on the board.
In application circuits where footprints for desired components
are not available on the board, the user is encouraged to find ways
to include them. For example, if an additional shunt element
were required, the user could scrape some solder mask away
from the ground plane and trace (if necessary) to make a place
for the additional part. Furthermore, 1206 elements can be
stacked on top of each other to implement a parallel circuit. An
example of this would be stacking capacitors across R17 and
R18 to realize a zero in the closed-loop transfer function. This is
one way to insert pre-emphasis in a line-driver application.
