Port Functions
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| GND | Ground | Ground is provided through the backside of the die. The backside must be connected to a DC/RF ground with high thermal and electrical conductivity. |  |
| RF In | Input | This pad is the RF input of the device. This pad is DC open and matched to 50 Ω at frequency range 10 - 25 GHz. |  |
| RF Out | Output | This is the RF output of the device. This pad is DC open and matched to 50 Ω at frequency range 20 – 50 GHz. | |
| VDA | Positive bias | Drain bias for the input amplifier. This pad must be connected to a positive power supply. Set this voltage to +5V for normal operation. |  |
| VDB | Positive bias | Drain bias for the output amplifier. This pad must be connected to a positive power supply. Set this voltage to +5V for normal operation. | |
| VG1A | Negative bias | Gate control for the input amplifier. This pad must be connected to a negative power supply. Set this voltage to -0.15V for normal operation. |  |
| VG1B | Negative bias | Gate control for the output amplifier. This pad must be connected to a negative power supply. Set this voltage to -0.15V for normal operation. | |
