1 VG1 Supply Voltage for MMIC 1 Gates. This pin is typically −1.3 V dc. Pin 1 is connected internally to Pin 3. 2 GNDDC Power Supply Ground. 3 VG1 Supply Voltage for MMIC 1 Gates. This pin is typically −1.3 V dc. Pin 3 is connected internally to Pin 1. 4 GNDRFIN RF Input Ground. 5 RFIN RF Input. This pin is dc-coupled and matched to 50 Ω. 6 GNDRFIN RF Input Ground. 7 VG2 Supply Voltage for MMIC 2 Gates. This pin is typically −1.3 V dc. Pin 7 is connected internally to Pin 9. 8 GNDDC Power Supply Ground. 9 VG2 Supply Voltage for MMIC 2 Gates. This pin is typically −1.3 V dc. Pin 9 is connected internally to Pin 7. 10 GNDDC Power Supply Ground. 11 VDD2 Supply Voltage for MMIC 2 Drains. 12 NIC Not Internally Connected. However, this pin can be connected externally to the RF and/or dc ground. 13 GNDRFOUT RF Output Ground. 14 RFOUT RF Output. This pin is ac-coupled and matched to 50 Ω. 15 GNDRFOUT RF Output Ground. 16 GNDDC Power Supply Ground. 17 VDD1 Supply Voltage for MMIC 1 Drains. 18 NIC Not Internally Connected. However, this pin can be connected externally to the RF and/or dc ground. Package Base GND The package base must be mounted to a suitable heat sink for the RF and dc ground. It is recommended to use 0-80 socket cap screws.
