ADL5531-EVALZ is a 4-layer, FR4-based evaluation board. For normal operation it requires a single 5 V/100 mA power supply. The 5 V power supply should be connected to the test loops labeled VPOS and GND. Alternatively, the power supply connections may be made via the two pin header, W-1. The RF input is applied to the SMA connector labeled RFIN. The RF output is available at the SMA connector labeled RFOUT.
