Port Configuration and Functions
Port Functions
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| GND | Ground | Ground paddle and non-connected pins must be connected to a DC/RF ground potential with high thermal and electrical conductivity, and low inductance. |  |
| Pin 11 | Vd | Pin 11 is the DC bias supply for the amplifier. This pin should be connected to the same supply voltage being used to supply the pin 8 "RF Out / Vd" bias-tee. |  |
| Pin 2 | RF In / Vg | Pin 2 is the RF input of the amplifier and also provides DC bias to the amplifier. This input in internally RF matched to 50 Ohms and requires a bias-tee to a negative DC bias voltage. The bias voltage applied to this pin directly controls the drain current (Id into pin 8) of the amplifier. As the voltage on this pin becomes more negative, drain current decreases. Voltage should be applied to pin 2 before pin 11 "Vd" and pin 8 "RF Out/Vd". See the section on Sequencing Requirements for more details. Current Ig will flow out of this port. The -Vg supply should be capable of sinking current up to 30mA. |  |
| Pin 8 | RF Out / Vd | Pin 8 is the RF output and primary DC power supply of the amplifier. This pin is internally RF matched to 50 ohms and requires an external bias-tee connected to a positive DC supply voltage. Voltage should be applied to pin 2 "RF In/Vg" before applying voltage to pin 8 and pin 11. See the section on Sequencing Requirements for more details. | |
| Pins 1,3,4,5,6,7,9,10,12 | Non-connect (NC) | These pins are not internally connected to the amplifier die. It is recommended to connect these pins to ground to provide RF isolation and mechanical stability. See the recommended landing pattern for details. Datasheet performance was measured with these pins connected to GND. | - |
