Port Configuration and Functions
Port Functions
| Port | Function | Connector Type | Description | DC Equivalent Circuit |
|---|---|---|---|---|
| GND | Ground | - | The housing or outside of the coaxial cables must be connected to a DC/RF ground potential with high thermal and electrical conductivity. |  |
| RF In | RF Input | - | The amplifier’s RF Input port is matched to 50 Ω and has built-in DC blocking capacitors. |  |
| RF Out | RF Output | - | The amplifier’s RF Output port is matched to 50 Ω and has built-in DC blocking capacitors. | |
| Vd | Positive DC Supply Vd | - | The VD pin supplies DC voltage to the drain of the amplifier IC. |  |
| Vg | Gate Bias Pin | - | VG provides bias for an internal current mirror that sets the current draw for the amplifier. Current is limited by an internal series resistor. Increasing voltage on this pin will increase gain at the expense of efficiency. |  |

Specifications
Absolute Maximum Ratings
The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If these limits are exceeded, the device may become inoperable or have a reduced lifetime. Reliability limits are individual, instantaneous catastrophic limits only. Functional operation limits are indicated below. Operation of the device at multiple absolute maximum limits or for extended periods at a single limit can cause degradation and damage to the device.
| Parameter | Maximum Rating | Unit |
|---|---|---|
| Drain Current (RF Applied) | 60 | mA |
| Drain Supply Voltage (Vd) | 8 | V |
| Maximum Operating Temperature for MTTF > 1E6 hours | 85 | °C |
| Maximum Storage Temperature | 125 | °C |
| Minimum Operating Temperature for MTTF > 1E6 hours | -40 | °C |
| Minimum Storage Temperature | -55 | °C |
| Reference Bias Current (Ig) | 15 | mA |
| Reference Bias Voltage (Vg) | 6.5 | V |
| RF Input Power | 20 | dBm |

Recommended Operating Conditions
The Recommended Operating Conditions indicate the limits, inside which the device should be operated, to guarantee the performance given in Electrical Specifications. Operating outside these limits may not necessarily cause damage to the device, but the performance may degrade outside the limits of the Electrical Specifications. For limits, above which damage may occur, see Absolute Maximum Ratings.
| Parameter | Min | Nominal | Max | Unit |
