ADRF5031 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS Figure 3. Pin Configuration (Top View) Table 6. Pin Function Descriptions Pin No. Mnemonic Description
1, 2, 4, 5, 6, 7, 9, 10, 13, 16, 17, 19, 20 GND Ground. The GND pins must be connected to the RF and /DC ground of the PCB. 3 RFC RF Common Port. The RFC pin is DC-coupled to 0 V. No DC-blocking capacitor is necessary when the RF line potential is equal to 0 V DC. See Figure 4 for the interface schematic. 8 RF1 RF Port 1. The RF1 pin is DC-coupled to 0 V. No DC-blocking capacitor is necessary when the RF line potential is equal to 0 V DC. See Figure 4 for the interface schematic. 11 VDD Positive Supply Voltage. See Figure 6 for the interface schematic. 12 CTRL Control Input Voltage. See Figure 5 for the interface schematic. 14 EN Enable Input Voltage. See Table 7 for the truth table. See Figure 5 for the interface schematic. 15 VSS Negative Supply Voltage. See Figure 7 for the interface schematic. 18 RF2 RF Port 2. The RF2 pin is DC-coupled to 0 V. No DC-blocking capacitor is necessary when the RF line potential is equal to 0 V DC. See Figure 4 for the interface schematic EPAD Exposed Pad. The exposed pad must be connected to the RF and DC ground of the PCB.
