APPLICATIONS INFORMATION

EVALUATION BOARD

The ADL6012-EVALZ is a fully populated, 4-layer, Rogers 4003A

and FR4-based evaluation board. For normal operation, the

board requires a 3.3 V to 5 V power supply. Connect the power

supply to the VPOS and GND test loops. Apply the RF input to

RFIN at the 1.85 mm connector. The differential envelope

output signal is ac-coupled and is available on the connectors

labelled VENV+ and VENV−. The dc envelope output voltage

and the output common-mode voltage can be measured at the

test points labeled VENV+_TP and VENV-TP. The output

common-mode voltage can be set externally by the VOCM turret.

See the ADL6012-EVALZ user guide for additional information

on the eval board.
