The ADL5903-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a 3.0 V to 5.0 V/15 mA power supply. The power supply must be connected to the test loops labeled VPOS and COMM. The RF input signal is applied to the SMA connector (RFIN). The output voltage is available on the SMA connector (VOUT) or on the test loop (OUT).
