Solder the exposed pad on the underside of the ADL5725 to a low thermal and electrical impedance ground plane. This pad is

typically soldered to an exposed opening in the solder mask on
7 B) d
the evaluation board. Connect the ground vias to all other
( 6
ground layers on the evaluation board to maximize heat
URE 5 IG
dissipation from the device package.

This section provides the test results that compare the ADL5725
–5 IP T
using a differential vs. single-ended output. When using the
U P –10 IN
device as a single-ended output, use the RFOP output of the evaluation board and terminate RFON to 50 Ω. Note that the

converse can be done as well; however, doing so produces
–20
slightly different results from the plots shown in this section because there is some amplitude imbalance between the two
