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 | RF | Pin 11 is DC open and AC matched to 50 Ohms from 18 to 55 GHz. Blocking capacitor is optional. |  |
| Pin 16 | Positive DC Supply Vd | Pins 16 provides +2.5V to +4V DC voltage to the amplifier’s third stage. Negative voltage must be supplied to Pin 5 before turning on the positive supply voltage. |  |
| Pin 17 | Positive DC Supply Vd | Pins 17 provides +2.5V to +4V DC voltage to the amplifier’s second stage. Negative voltage must be supplied to Pin 5 before turning on the positive supply voltage. | |
| Pin 18 | Positive DC Supply Vd | Pins 18 provides +2.5V to +4V DC voltage to the amplifier’s first stage. Negative voltage must be supplied to Pin 5 before turning on the positive supply voltage. | |
| Pin 2 | LO | Pin 2 is the input of the integrated LO driver amplifier and is matched to 50 ohms. It is internally DC blocked. | |
| Pin 5 | Negative DC Supply Vg | Pin 5 requires -0.4V to -0.6V of DC voltage. This must be turned on before turning on the positive supply voltage to Pin 5. |  |
| Pin 8 | IF | Pin 8 is DC coupled to the diodes. Blocking capacitor is optional. |  |
