EVALUATION BOARD
A populated, RoHS-compliant ADL5385 evaluation board is available. The ADL5385 has an exposed paddle underneath the package,
which is soldered to the board. The evaluation board is designed without any components on the underside so that heat can be applied to
the underside for easy removal and replacement of the ADL5385.

Function
Power Supply and Ground Clip Leads.
Device Enable. Set SW21 to the OFF position to power down the device; set SW21 to the ON
position to enable the device. Part can be driven from an external enable control source via the
test point or the SMA connector. R21 provides a 50 Ω termination for any 50 Ω driving source.
Baseband Input Filters. These components can be used to implement a low-pass filter for the
baseband signals.
