1 VDD_PA Drain Bias Voltage. See Table 2. 2 VBIAS Current Mirror Bias Resistor Pin. Use this pin to set the current to the internal resistor by the external resistor. See Figure 9 for the interface schematic. 3, 5, 8, 10 to 12, 14, 17, 19 to GND RF and DC Ground. See Figure 6 for the interface schematic. 22, 24 to 26, 28 4 RFIN RF Input. These pins are dc-coupled and matched to 50 Ω. A dc blocking capacitor is required if the RF line potential is not equal to 0 V dc. 6, 7 VA, VB Control Input. See Table 2, Table 4, and Table 5. See Figure 8 and Figure 7 for the interface schematics. 9, 13 OUT_B, These pins are dc-coupled and matched to 50 Ω. A dc blocking capacitor is required if the RF IN_B line potential is not equal to 0 V dc. 15 VSS_SW Negative Bias Voltage. See Table 2. 16 VDD_SW Positive Bias Voltage. See Table 2. 18 RFOUT RF Output. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required if the RF line potential is not equal to 0 V dc. 23, 27 IN_A, These pins are dc-coupled and matched to 50 Ω. A dc blocking capacitor is required if the RF OUT_A line potential is not equal to 0 V dc. EPAD Exposed Pad. The exposed pad must be connected to RF and dc ground.
