The ADRF5021-EVALZ is a fully populated, 4-layer, RO4003 based evaluation board. Two power supply of +3.3 V and -2.5 V should be applied to the VDD and VSS test points respectively while ground reference is connected to the GND test point.

Two control voltages of 0/+3.3 V that select the switch state are applied to the EN and CTRL test points. The RF input signal can be applied to the end-launch, 2.4 mm RF connector labeled RFC and the RF output signals can be measured on the end-launch, 2.4 mm RF connectors labeled RF1 and RF2.
