Pin No. Mnemonic Description
1 RF4
RF Port 4. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin.
2, 3, 5, 10,
GND
Ground. The package bottom has an exposed metal pad that must connect to the printed circuit board (PCB)
RF/dc ground. See Figure 5 for the GND interface schematic.
4 RF3 RF Port 3. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin.
6 V
DD
Supply Voltage.
7 B Logic Control Input B. See Figure 6 for the control input interface schematic. See Table 6 and the
recommended input control voltages range in Table 2.
8 A Logic Control Input A. See Figure 6 for the control input interface schematic. See Table 6 and the
recommended input control voltages range in Table 2.
9 RF2 RF Port 2. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin.
12 RF1 RF Port 1. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin.
15 RFC RF Common Port. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin.
EPAD Exposed Pad. The exposed pad must connect to RF/dc ground.
